Hooking up a C# event to a C++/CLI class

Some of the changes since the previous version: This has been replaced with the following C implementation: Size allows us to support both 32 and bit processes return vtblAddresses. The capture method used in Direct3D 10 and 11 is also more thread-safe allowing us to extract data from the resulting texture on a background thread. This reduces the impact to the frame rate. We are also able to copy only the region of the backbuffer that we are actually interested in — making the capture of smaller regions quicker as less data needs to be copied to system memory. This also will make capturing a sequence of frames for use in video production much easier.

March 14, 11 Comments In the previous post we looked at some basic features of WS-Federation in a. Dynamic WS-Federation configuration at runtime WS-Federation authentication events The features will be presented in a demo at the end as usual. Those settings are of course static. However, occasionally you may need to set some properties dynamically.

You might have these values stored in a database or you need to query a web service for the right configuration. You can achieve this using Global.

I worked on VSTO C# Excel I tried and searched many approaches to find a way to trigger more events. One of the important events I need is, cells formatted event .

First, delegates allow you to take the address not only of shared methods but also of instance methods. In the case of an instance function, both the function address and object instance are stored, allowing for correct invocation of virtual functions. The second special property is that delegates are combinable. When you combine two delegates which must be of the same delegate type , invoking the resulting delegate will call both delegates in order of combination.

Combining delegates that have return types is possible, but the return value of the delegate invocation will be the return value of the last function invoked. VB allows syntactic shortcuts when creating delegates. NET perspective, creating a delegate involves invoking a constructor on the delegate class that takes an object instance possibly Nothing for shared methods and the address of a method.

I believe C is adding this feature in C , but I could be wrong about that. NET style Once we have delegates, events become possible. An event raised by a class is defined by three things: The delegate type defines the signature of the event handler — in other words, the delegates define the arguments that will be passed to a method that gets called when the event occurs.

The add and remove listener methods allow other objects to start and stop listening to the event.

Methods[ edit ] Typically hooks are inserted while software is already running, but hooking is a tactic that can also be employed prior to the application being started. Both these techniques are described in greater detail below. Physical modification[ edit ] By physically modifying an executable or library before an application is running, through techniques of reverse engineering , you can also achieve hooking.

This is typically used to intercept function calls to either monitor or replace them entirely.

The only directory you can move a file to on a single key press is the Recycle Bin. So I decided to fix that by mapping F12 to a smart move feature that moves the selected files to Documents, Pictures, Music or Videos, depending on the extension. While doing that, I discovered that adding a keyboard hook to Windows Explorer is far from trivial.

There’s a good reason for that: I’m posting this to help anyone who’s trying to find out how to hook to keyboard events in Windows Explorer. The sample covers my Smart Move application, which maps F12 to this move feature. I must warn you that the project is Vista-specific. It will fail to register in XP, due to missing dependencies. I’ll provide pointers on how to alter it to work on XP and earlier where appropriate.

Disclaimer I’m not a native developer by trade. I’m a C developer, with a huge VB background.


The following procedures show how to hook up an existing method to an event by getting all the necessary types through reflection, and how to create a dynamic method using reflection emit and hook it up to an event. Note For another way to hook up an event-handling delegate, see the code example for the AddEventHandler method of the EventInfo class.

To hook up a delegate using reflection Load an assembly that contains a type that raises events. Assemblies are usually loaded with the Assembly. To keep this example simple, a derived form in the current assembly is used, so the GetExecutingAssembly method is used to load the current assembly. Assembly Get a Type object representing the type, and create an instance of the type.

Lets now look at how it works in practice. Before we start After adding k div objects After adding OnClick events to the k div objects After removing the DIVs, but not the associated events After removing the DIVs and associated events Its very easy to see how without cleaning out objects and events after use, they could easily creep up and up and ultimately have a negative impact on performance.

So, if you set it up, don’t forget to tear it down! Careful with Knockout Observables Observables are a key aspect of Knockout, giving the ability to have two way binding between form fields, data and the model data, and more. However, one has to be extremely careful only to use them where necessary. It is very easy to fall into the trap of having long linked chained observables that cascade one into the other and cause the application to slow down badly.


Do you want to capture keyboard input in anything but a visible input field in your application? You will need to use some native, unmanaged Windows methods out of the Windows User SetWindowsHookEx , whose translation to. NET managed memory land via the C language can be found at: Armed with your new low-level knowledge, add the methods you need to your application and put them to good and careful use! An instance of this type can broadcast an event containing the key pressed, every time anything is pressed on the keyboard, whether the input is done in the host application or not.

Having been quite fond of Java myself, I must admit that it was a great language. It filled a void in Internet software development that other languages left open during the late s and early s. However, we now have a new choice with C , which has its own signature and style and which is definitely not the same as Java.

C introduces several modern language elements that Java doesn’t even have. Furthermore, a peek under the hood will reveal semantics that differentiate C from any other language. This article explores each of these areas, supporting the perspective that C is its own language. Types C has unsigned integral types byte, ushort, uint, ulong. Furthermore, C has a decimal type that holds a floating-point number and is used primarily for financial calculations.

Now, if a C program uses these types, how can that look like Java, which doesn’t have any unsigned types or a decimal? Sure, Java has a byte type, but it’s signed, whereas the C sbyte with the letter s in front is signed and the two don’t look alike. Some of you may be thinking that it would be just as easy to use a Java double for financial calculations. However, with 28 digits of accuracy, the decimal type is not the same as a double.

Download FullCalendar from here. Download Twitter Bootstrap I am using the stable version 2. In your MVC project, add the bootstrap files to your script bundles. This is in BundleConfig. We will do our work in the default index.

How to create an event in C#. i have a class that contain status method, this method not called automatically but i have to do that every time i need to check the return of the status method what i need to do is to create an event that fires when the return value of the status method changes.

It’s already the case, I posted all the code, see my edit. Feb 1 ’12 at You either need to specify a 0 hModule and a thread inside your own process. In which case you can only observe windows in your own process. Or you specify 0 or an external thread and a non null hModule. But as I wrote, the second approach is likely impossible in. Then once an event happens, your dll gets injected into the target process and your hook method gets called.

For example, it is often a powerful time-saver to have a menu command raise the same event as a button on your form does if they expose the same functionality. To connect multiple events to a single event handler in Visual Basic Right-click the form and choose View Code. From the Class Name drop-down box, select one of the controls that you want to have the event handler handle.

How to: Subscribe to and Unsubscribe from Events (C# Programming Guide) 07/20/; 3 minutes to read Contributors. all; In this article. You subscribe to an event that is published by another class when you want to write custom code that is called when that event is raised.

A programmatic name of the event source. Remarks The script engine uses information provided by the AddEventSource method to hook up events to the named event source. It obtains event sources by calling the IVsaSite. GetEventSourceInstance method, which is implemented by the host. The AddEventSource method creates a class that handles events raised by a host-provided object.

NET script engine does not support this method. In cases where the JScript. NET engine must hook up an event, you must do so using a global item. Rather than event sources, the JScript. NET engine uses AppGlobal item types. For more information, see VsaItemType. Within the code item, you can access the event source object by name, and, once accessed, you can write event handlers against the object.

There are two groups of these hooks: Client-side hooks are triggered by operations such as committing and merging, while server-side hooks run on network operations such as receiving pushed commits. You can use these hooks for all sorts of reasons. Installing a Hook The hooks are all stored in the hooks subdirectory of the Git directory.

When you initialize a new repository with git init, Git populates the hooks directory with a bunch of example scripts, many of which are useful by themselves; but they also document the input values of each script.

Prior to that you might be familiar with the bidirectional communication channel, known as WebSockets, used very much and tons of server implementations are available on the internet. However the second server-push technology of HTML5 yet stays in the shadows. To enable efficient server-to-client streaming of event data it is basically text-based. Facebook, Twitter, stock exchange updates and and so on generated on the server.

Basically we have the following two types of components that SSE introduces: EventSource Interface Event Stream The EventSource Interface allows the client to receive push notifications from the server as DOM events and and the “event stream” data format, that is used to deliver the individual updates. Since for a long time we previously considered the HTTP protocol as a request-response model that uses bidirectional communication, in other words when you as a client sends a request to the server and waits for the response then again sends a future request.

What clear to you.? Here you see that the server cannot communicate with the client unless it’s requested, this process is also called COMET.

Open your document for example, Window1. Your document will open for editing. Make sure you are in Design view, by clicking the Design tab on the right side of the artboard.

The prepare-commit-msg hook is run before the commit message editor is fired up but after the default message is created. It lets you edit the default message before the commit author sees it. This hook takes a few parameters: the path to the file that holds the commit message so far, the type of commit, and the commit SHA-1 if this is an amended commit.

The discussion starts with an introduction to the concept of delegates and then it extends that concept to events and event handling in. Finally, I apply these concepts to GUI event handling using windows forms. Complete code is provided in each step of the discussions. Introduction Event handling is familiar to any developer who has programmed graphical user interfaces GUI. When a user interacts with a GUI control e. Events can also be generated without user interactions. Event handlers are methods in an object that are executed in response to some events occurring in the application.

To understand the event handling model of. Net framework, we need to understand the concept of delegate. Delegates in C A delegate in C allows you to pass methods of one class to objects of other classes that can call those methods. You can pass method m in Class A, wrapped in a delegate, to class B and Class B will be able to call method m in class A.
