MVC3: Guid Data Type

This base class offers most of the mechanics to host the runtime, however no software particular implementation for rendering. There are rendering capabilities but they only call the engine immediately and provide no caching – there's no context to determine the method to cache and reuse templates. The key methods are Start and Stop and their major purpose is to begin a brand new AppDomain and shut it down when requested. The RenderTemplateFromAssembly technique mainly requires the namespace and sophistication to instantate and creates an occasion of the category using InstantiateTemplateClass(). It then invokes the method with InvokeTemplateInstance(). In the default mode instantiation units the Engine and HostContainer so the template can name again into the template engine, and the context is about when the template methodology is invoked. Examining the code above you probably can see that we're first checking to see if an image was uploaded. If not, we're returning a WrappedJsonResult reporting the error to the calling script. If a file was there we generate a file name, save it to the server, and return the information again to the script. I should notice that within the event of an error, it might not be necessary to return ImagePath and in the occasion of a succesful save you wouldn't must return Message. I've included it in both return values for completeness and so the javascript can assume that it is all the time there. This is the core Razor hosting which supplies the fundamentals of loading a template, compiling it into an meeting and executing it. This is pretty easy, however without a host container that can cache assemblies based mostly on some criteria templates are recompiled and re-created every time which is inefficient .

The base engine wrapper implementation additionally helps hosting the Razor runtime in a separate AppDomain for safety and the ability to unload it on demand. To hold issues simple we're simply going to do every thing in our controller methodology. We're additionally not going to do any validation, we're going to assume that each file uploaded is a jpg and we'll return the trail to the picture in addition to a standing message. To show what to do in the occasion of an error, we may even return some status info in our JSON result. The beauty of dynamics in .NET and JSON allows us to do a lot of nice stuff. For now, let's go forward and create a controller method. But the facility of default mannequin binding extends past the flat data model of a easy input type or record of data. Using a couple of straightforward coding methods, developers can use ASP.NET to create varieties and acquire data for hierarchical entity relationships. RenderTemplate() is pretty excessive degree and it handles loading of the runtime, compiling into an meeting and rendering of the template. If you need extra management you can use the lower stage methods to regulate every step of the way in which which is important for the HostContainers I'll discuss later. Basically for those situations you wish to separate out loading of the engine, compiling into an meeting and then rendering the template from the assembly. In the code above a new meeting is created for each template rendered which is inefficient and uses up resources. Depending on the dimensions of your templates and how typically you hearth them you can chew through memory in a quick time. The Razor Engine then again is pretty light weight and completely decoupled from the ASP.NET runtime and the HTTP processing.

Rather it's a pure template engine whose sole objective is to render textual content templates. It's very useful resource intensive and has potential points with versioning in various completely different variations of .NET. So we've gone from 17 traces of code to about 7-8 lines of code right here. The first thing to notice is that in MVC 3 we now have a property known as "AdditionalValues" that hangs off of the ModelMetadata property. This is routinely populated by any attributes on the property. There is no extra need for me to explicitly write Reflection code to GetCustomAttributes() after which examine to see if those attributes were current. I can just call TryGetValue() on the dictionary to see in the occasion that they were present. And there isn't any issues calling the Contains() technique on this dynamic object as a end result of at runtime the DLR has resolved that it's a generic List. As regards the listed advantages of GUIDs vs integers, properly, not a single certainly one of them is legitimate. Whenever loading a record sourced from another database all the time deprecated the first key and generate a brand new integer major key worth for that document. As regards duplication, in case you have viable algorithms in place there is no chance of duplication . As regards loading massive data set, GUID supply no profit, however in fact will critically fragment the info files. Integer data varieties are perfectly fitted to loading small or extraordinarily massive data set, that is when you understand how to put in writing first rate code. Not fairly positive how to word this question however here it goes. I am engaged on a project the place a number of client applications are accessing one data supply through a WCF service. It is most likely not relevant but the WCF service is utilizing entity framework to entry this data source. Whenever a consumer has queried a record for enhancing, I would like to preve... Data is retrieved from the DataReader into a method that returns a CatProd item which is then added to the IList collection of the CatProd type.

For occasion, we've a must current a really giant HTML-based form both online and in a WinForms WebBrowser management. We wish to leverage the same precise templates for each, with out having to have .cshtml information editable by the consumer on the filesystem within the WinForms app. Before I get into how internet hosting with Razor works, let's take a look at how you can stand up and working quickly with the wrapper lessons offered. So why might you host a template engine in your non-Web application? Template rendering is useful in lots of locations and I even have a selection of purposes that make heavy use of it. This is an older product and it's not really utilizing .NET at the moment – and that is one cause I'm looking at Razor for script hosting in the meanwhile. Microsoft's new Razor HTML Rendering Engine that is currently transport with ASP.NET MVC previews can be used exterior of ASP.NET. Razor is an alternative view engine that can be utilized instead of the ASP.NET Page engine that currently works with ASP.NET WebForms and MVC. Action method with the encoding type set to multipart/form-data for file addContent. Method of Entity Framework code-first migrations, we have populated the database with a few customers, orders, and gadgets. If you run the instance resolution the application will create the database and add the identical data (the GUID's created by your laptop for the necessary thing fields will be totally different than those shown). Many builders know that they'll create varieties on net pages with a minimal of code using ASP.NET mannequin binding.

Visual Studio's default MVC view templates will even create a regular listing, create, edit, and delete views without any extra programming. New SharePoint hybrid search choice – Hybrid search is receiving a huge update / improve later this yr. In it's current kind SharePoint hybrid search includes separate search service functions / indices for on-prem farms and Office 365 / SharePoint Online. If you question one source you presumably can federate the question to the other and get results in a separate result block. The drawback though is that configuration could be fairly advanced, search outcomes aren't built-in (in-line with each other), and you probably have a lot of servers on-prem for the search service. Additionally you will want a much smaller on-prem server footprint to assist search (the instance given was going from 10+ search servers down to 2). This is a giant win for my part and I can't want to test it out when it is launched. The HomeController uses a Dictionary to save the progresses of all tasks. The Start action provides a new entry to this dictionary and starts a new Task that simulates the lengthy running operation. The Progress action simply returns the progress for a given GUID that uniquely identifies a task. Both actions return a JSON-result to enable easily processing of the data on the shopper side. @Donnie - T4 is particular to Visual Studio so you want Visual Studio to make use of it which makes it useless for standalone applications. Also I've by no means been a fan of T4 since there's no decent editor help in VS even for it . Bottom line is if you want to generated code from inside visual studio T4 is the simplest alternative as the the setting will routinely pick up templates and convert them to output information. Once we can load templates in a distant AppDomain we are ready to add some additional performance like assembly caching based mostly on application particular options. One of my typical situations is to render templates out of a scripts folder.

So all templates reside in a folder they usually change infrequently. So a Folder based mostly host that may compile these templates once and then solely recompile them if something modifications could be best. In order to host the templates in a separate AppDomain the best factor to do is to run the entire RazorEngine in a separate AppDomain. Then all interaction occurs within the different AppDomain and no further modifications should be made. To facilitate this there is a RazorEngineFactory which has strategies that may instantiate the RazorHost in a separate AppDomain as well as in the native AppDomain. The host creates the distant occasion and then hangs on to it to keep it alive as well as providing methods to close down the AppDomain and reload the engine. The basic Razor Hosting API is pretty easy and you may host Razor with a (large-ish) handful of lines of code. The name of your file enter "imageFile" should match the parameter name of your UploadImage method. Make sure you substitute "YourController" with the name of the controller UploadImage is in. You'll additionally notice that I've positioned the iFrame off of the display quite than merely changing it is display property through CSS. Some browser versions do not all the time play good with hidden iFrames so I've simply positioned it off the web page as an alternative. We've also added an "Images" div that we'll use to shovel the photographs in after they have been uploaded.

CodeGuru covers matters associated to Microsoft-related software growth, mobile development, database administration, and net utility programming. Cloud providers corresponding to Microsoft Azure and database choices together with SQL Server and MSSQL are also frequently coated. The errorMessage property of the TokenType class is used to move back in the login failed for a username/password error. Basically if errorMessage is "" then every thing went OK. If it incorporates the textual content "fail" then the username/password combination isn't valid so the cellphone app will show that in a message box and reset the show to allow the consumer to aim to go online again. If an exception occurred in the course of the login process this is captured by the service and put into the errorMessage property. The telephone app will check this and for now display that error message to assist in debugging. The Grid plugin can be bound to a quantity of kinds of data collections together with arrays, xml, json, tsv, csv or distant data. To data bind the Grid to a knowledge source you should set its supply property to level to an occasion of jqxDataAdapter. So it's simpler to cross the data from the host down into the template utilizing this somewhat clumsy approach of set and ahead. It's ugly, but it's something that can be hidden within the host container implementation as I've accomplished right here. The second issue is in attaching the onload occasion to the iFrame.

I actually spent hours making an attempt to use jQuery to correctly attach an event to the iFrame, using totally different permutations of both .load() and .ready(). For some reason these occasions have been at all times connected instead to the parent page and only ever fired when the father or mother web page was first ready. Because of this and a couple other small issues that are doubtless due to my limited jQuery data, I used a combine of jQuery and straight up javascript in my software. The iFrame's onload event will fire the primary time it's loaded, so I also created a boolean variable to trace whether or not it is the first load. In order to make the AJAX fashion file uploads work, we have to to publish to an iFrame. We're going to position an iFrame off the web page to cover it and then publish to it. We'll return a outcome to the web page and retrieve it with our javascript. It's essential to note that as a outcome of safety limitations, the web page being posted to should be on the same domain because the page you are posting from. Also, I will not be demonstrating any progress indicators but in production I would extremely advocate you disable the addContent from and use a progress indicator to let your customers know the file is importing. Also, this resolution shall be using a single hidden iFrame, however for multiple simultaneous uploads you can dynamically generate the iFrames and post to them. Recently I was engaged on a project that required upload of pictures. I wished to addContent the photographs AJAX style without refreshing the web page and thought jQuery would be a good fit. Using jQuery to submit normal forms is very simple, however when posting multi-part types for importing recordsdata it's not so intuitive. This is as a end result of of browser safety restrictions and sandboxing. Today I'm going to indicate you the way to faux an asynchronous upload without reloading the web page and get a end result again from the server. Many mainstream programming languages (like C and C++) deal with strings as a null terminated array of characters. The .NET Framework, nonetheless, treats strings as an immutable sequence of Unicode characters which cannot be modified after it has been created. Because strings are immutable, all operations which modify the string contents are literally creating new string cases and returning those.

The FileUpload helper gives builders a particularly fast and versatile approach to add multiple file addContent support to a form, utilizing javascript to deal with adding a quantity of file addContent controls. The GetHtml technique is used to render a file addContent control using the optionally available parameters proven above. The snippet above ends in the addContent management displayed below. In earlier version of the asp.net we have to bind controls with data supply control like SQL Data supply, Entity Data Source, Linq Data Source if we want to bind our server controls declaratively. Some developers choose to write down entire data access logic after which bind the information source with databind method. Model binding is something just like asp.net mvc binding. In earlier model of ASP.NET there is no approach to upload multiple information at same time. We want to use third get together management or we want to create customized management for that. But with asp.internet four.5 now its attainable to upload multiple file with file addContent control. For example we need to restore datbase however system doesn't enable as a end result of some one is related. There are three options in Model View Controller for passing data from controller to view. This article makes an attempt to elucidate the differences amongst ViewData, ViewBag and TempData with examples. ViewData and ViewBag are related and TempData performs additional accountability. The following are the necessary thing factors on those three objects. Saving data utilizing default binding could be a tricky course of -- the right strategy isn't well-documented.

This is also a situation the place the code fails silently. Developers will see their internet pages being populated with data accurately, however the values won't show up within the model when it arrives at the controller action for HttpPost. Properties in both of these classes to supply navigation between entities. The view models serve the practical objective of the view and are uncoupled from the entity relationships of the classes and the database tables. Accordingly, when two view models are used together they replicate the connection between the view models, quite than the entities from which their data is drawn. Project Siena – Project Siena looks like a viable different for many custom development scenarios. Essentially it is an app that permits you to build different apps. If you aren't acquainted with Project Siena you actually want to see it to grasp it. No "internal" FIM in SharePoint 2016 – SharePoint 2016 won't ship with a version of the Forefront Identity Manager product included. Your choices in 2016 will be the Active Directory Import (same as 2007 and re-introduced in 2013) or "external" FIM which is put in and managed outside of SharePoint Server. @Elmar - assemblies ought to be in the host application's assembly path (ie. startup folder or privateBin folder). If essential you'll have the ability to regulate the bin path with startup/config file settings to accomodate further folders. I prefer not using the CustomContext, as it for data, however it's my current workaround. I'm not in a position to consumer partial render, as the current implementation is just file primarily based. The static CreateRazorHostInAppDomain() is the important thing technique that startup code often calls. It uses a Current singleton occasion to an instance of itself that is created cross AppDomain and is saved alive as a end result of it's static. GetRazorHostInAppDomain really creates a cross-AppDomain occasion which first creates a model new AppDomain after which masses the RazorEngine into it.

Instantiate Object Inside Of Object Unity

We are instantiating the player prefab locally first. This is necessary because we need the reference to the object's PhotonView component. If we have successfully allocated an ID for the PhotonView, we are collecting all the data we want to send to the other clients and store them in an array of objects. In this example we are sending the position and the rotation of the instantiated object and - most important - the allocated ViewID. Afterwards we are creating the RaiseEventOptions and the SendOptions. With the RaiseEventOptions we make sure, that this event is added to the room's cache and only send to the other clients, because we already have instantiated our object locally.

With the SendOptions we just define, that this event is sent reliable. Finally we are using PhotonNetwork.RaiseEvent(...) to send our custom event to the server. In this case we are using CustomManualInstantiationEventCode, which is simply a byte value representing this certain event.

If allocating an ID for the PhotonView fails, we log an error message and destroy the previously instantiated object. While relying on BinaryFormatter can be convenient, it isn't possible to just serialize a game object hierarchy using a BinaryFormatter and deserialize it later. The game object hierarchy has to be recreated manually.

Also, writing every bit of data ourselves gives us total control and understanding. Besides that, manually writing data requires less space and memory, is quicker, and makes it easier to support an evolving save file format. Sometimes, games that have already been released drastically change what's stored after an update or expansion. Some of those games can then no longer load a player's old save files. Ideally, a game remains backwards-compatible with all its save file versions.

Suppose you're making a role-playing video game and you need an easier way to assign statistics, properties, and much more to various items. While you could use Unity prefabs to do this and then change the values of each individual copy of the prefab, this is an inconvenient way to go about the task. For starters, this method uses up more of your memory, something you may need to conserve if you plan on making a large game. In addition, if you must make any changes to the in-game objects, it's simply not as efficient to do so when there are several copies of prefabs lying around. This especially becomes an issue if you have a larger team to work with, so you'll want to make things easier to change for other team members. Even if you're not in a team, this method would just be harder on you as you work.

RandomizeStats, the second method, does exactly as the name suggests. It changes the values of the Scriptable Object to a random number between 1 and 20. Later on, you will program the project to update the user interface with the new values automatically. Data in a Scriptable Object is persistent, meaning that they'll remain the same for the session up until the game is closed.

This is especially helpful if you're making a game that consists of multiple scenes since ordinarily old objects are deleted, and new ones are reloaded as a new scene is opened. However, Scriptable Object data is untouched in the transition between scenes. In addition, the data remains the same while working in the Unity editor until the editor itself is closed. It's always helpful to see these things in action, create a new project. This project shows off Scriptable Objects and how they can help you. The project consists of three game objects meant to represent three characters.

Each character inherits some values from a Scriptable Object. Those values are maximum health, attack, defense, speed, and a name and color for the character. A simple user interface displays these values so you can easily see the results of applying Scriptable Objects.

Now that you have an end goal, it's time to get creating. To make things easier in a situation like this, you have Scriptable Objects at your disposal. The Unity developer creates a basic template for these containers, defining what information each object should contain. Then the Scriptable Objects are created from that template, which are then used by Unity game objects.

In the above example, a single Scriptable Object can be used to define what the different properties of an item are. Then that Scriptable Object is referenced by all copies of the item. Before if you wanted to change an item's stats, you'd have to change the values of every single copy of the item. Now with Scriptable Objects, you only need to change one object and all objects getting data from that Scriptable Object change at the same time.

Our cubes are simple objects, without any custom components attached. So the only thing that's to save is the transform component. Let's create a PersistableObject component script that knows how to save and load that data.

It simply extends MonoBehaviour and has a public Save method and Load method with a GameDataWriter or GameDataReader parameter respectively. Have it save the transform position, rotation, and scale, and load them in the same order. To support saving and loading during a single play session, it would be sufficient to keep a list of transformation data in memory. Copy the position, rotation, and scale of all cubes on a save, and reset the game and spawn cubes using the remembered data on a load.

However, a true save system is able to remember the game state even after the game is terminated. This requires the game state to be persisted somewhere outside the game. The most straightforward way is to store the data in a file. To create these primitive game objects at runtime, we use the method GameObject.CreatePrimitive. This method creates the primitive object that is given as a parameter. The primitive geometric object will be created at the center of the scene.

Therefore, you need to set its position or rotation if you would like to change its transform right after the object is created. We set its parent to be the object pulling manager, and finally we store it in the bullet's array, in the bullet's list. And after we do this, we type return prefab instance. And back in the player, instead of using this instantiate method call here, we're going to use the get bullet from the object pool manager.

We have now set the entire ground work for making the object pooling to fully work. So now we need to go to the object pooling manager, and we have to make the get bullet method to work. And how we're going to do this, let's take off these two lines. We want to iterate over all of the prefab instances that we have loaded here, and we need to check if any of them are inactive, because if it is then that's the bullet that we're going to use. So to do this, we're going to type for each game object bullet in bullets.

We're simply going to check that list for all of the bullets that we have. Prefabs allow us to prepare an object for the scene and thus, we can create instances of these prefabs during runtime or directly in the editor. They are useful especially when we want to modify these objects. Just modifying the prefab properties will affect each game object that is created from this prefab. So if we go to look at the object pooling manager, we have two bullets.

If I shoot one, you see that it got active and then deactivated. But then if I click again, the bullet quickly blinks in the screen. If you go to the bullet script, you're going to see that the live timers is only set in the start method. And very important to know is the start method is only called when the object is instantiated. But since this is going to be pooled, we're going to change the start to OnEnable. There's a lot of different approaches to ensure this.

A good starting point is the Unity component system itself. Complications may appear when particular components need to communicate with other systems of the application. For this, you can use interfaces to make parts of your system more abstract and reusable. It should be exclusively its controller's responsibility. In this article, I will continue with another beginner topic. In the previous article, we talked about finding game objects at runtime.

This time, I will write about how we create new game objects at runtime in Unity3D. In games, we always instantiate new game objects. These could be enemies, coins, obstacles, bullets, etc. Therefore, it is important to understand how these objects are created or in other words instantiated. Everyone dreamt about creating a shooter game once. Unity instantiate helps us to create projectiles.

It's very similar to the previous chapter, but this time let's increase the difficulty instantiating prefabs instead of cloning objects already in the scene. This is extremely useful because we don't have a bullet in the scene before the player shot. In void Update, I can simply type Instantiate, which then requires the name of the prefab I want to bring it into the game scene. I then reference the position of the transform, which will instantiate the prefab at the current position of the player, being that's the object this script is attached to. Finally I type Quaternion.identity, which is Unity's way of saying no rotation.

Naturally, you can create multiple types of Scriptable Objects for many types of objects. This example demonstrated their use via character classes, but there's also the aforementioned items example. It can even be used for much smaller objects, such as power-ups reminiscent of those found in arcade games. In using Scriptable Objects, you create a clean, easy system where you can change and load data with a few keystrokes and see the results almost instantly. Using Scriptable Objects also means fewer scripts to create, as you can use one template for multiple objects. Regardless of whether your project is big or small, or whether your team has many members or just yourself, Scriptable Objects can make everyone's development a little easier.

Now that we have a persistent object type, let's also create a PersistentStorage class to save such an object. It contains the same saving and loading logic as Game, except that it only saves and loads a single PersistableObject instance, provided via a parameter to public Save and Load methods. Make it a MonoBehaviour, so we can attach it to a game object and it can initialize its save path. Prototyping and implementation of functionality in Unity is quite easy. You can easily drag and drop any references to other objects, address every single object in the scene, and access every component it has.

However, this can also be potentially dangerous. On top of noticeable performance issues , there is also great danger in making parts of your code entirely dependent on each other. Or being dependent on other systems and scripts unique to your application, or even on the current scene, or current scenario. Try to take a more modular approach and create reusable parts which can be used in other parts of your application, or even shared across your whole application portfolio.

Build your framework and libraries on top of Unity API the same way you are building your knowledge base. In the constructor of AMyActor, we have set the default property values for the class. Note the use of the CreateDefaultSubobject function.

We can use it to create components and assign default properties to them. All the subobjects we create using this function act as a default template, so we can modify them in a subclass or Blueprint. Instead of calling destroy game object, instead of removing the bullet from the game entirely, we're going to type GameObject.SetActive false.

Otherwise the bullet would disappear after it has been instantiated. Okay, so we're going to make a new list that can store up to 20 bullets, which is good, okay. And for the getBullet, we have to worry about something, we need to store the references for the bullets, before we try to use the getBullet. So here, when we instantiate the prefabs, I'm going to type bullets.Add, in between parentheses, I'm going to pass prefabInstance, just like that, okay.

And if you go to Unity, well you're not going to see the changes yet, we're simply going to preload the bullets, they're going to be stored internally in the list, in a generic list. If we press play, and we look at the Hierarchy, you see that the ObjectPoolingManager has an arrow, because it contains several objects inside it. If you open, you're going to see the 20 bullets in there sleeping, in their dormant state. What we have to do, is we have to store all of the references for the bullets that we have here somewhere.

So here, I'm going to type private List of type GameObject and it's going to be named bullets, simple as that. Now we can loop through the list in BeginNewGame and destroy all the game objects that were instantiated. This works the same as for array, except that the length of the list is found via its Count property. Our game can spawn an arbitrary number of randomized cubes, which all get added to the scene. In order to destroy the cubes, we first need to find them.

To make this possible, we'll have Game keep track of a list of references to the objects it instantiated. You can create scenes in the Unity editor and populate them with object instances. This allows you to design fixed levels for your game.

The objects can have behavior attached to them, which can alter the state of the scene while in play mode. Often, new object instances are created during play. Bullets are fired, enemies spawn, random loot appears, and so on. It might even be possible for players to create custom levels inside the game.
