Balloon Detection

Question

Using WinXP. What I need to do (pref in VB or C #) is to detect when another (closed source) program displays a balloon with a notification in the tray - and grab the details. Any help would be greatly appreciated. Thanks

Answer 1

In such situations, I used the Microsoft Spy ++ tool to capture window information, and then use pinvoke calls FindWindowto detect when that window is present.

I have not tried with a notification, but I assume that calling pinvoke in GetTextwill load the contents.

, pinvoke .net.

Edit:

, .NET. , () DLL-. Windows DLL , DLL , .NET CLR, . ( CLR , , .)

So, you have to create your hooks in your own (unmanaged) DLL. It’s possible to go from here to a managed application, for example, Michael Kennedy did it in the Code Project , but to do it correctly and handle the types of hooks that I mentioned above, you will need to use interprocess communication, a step that Michael Kennedy left. In general, for the purpose that you described, it would be easier to just build everything in your own code.
