[2.0] Interacting with my app, other instance

[BrightSoul]

Hello,
I restricted my application to only one instance. When the app is running and the user tries to launch it again, the new instance is not created and Application.Exit() is invoked instead.

Now, here's the problem: just before invoking Application.Exit(), I want to send a string message to the main, running instance. How can I do this with some Win32 API or other managed -more elegant- way? I'd like to avoid .NET Remoting.

Thanks for helping.

VB 2005 has an inbuilt way to do this. You might like to investigate how that's done by opening the Framework assemblies involved using .NET Reflector. I have also seen numerous articles about incorporating the VB My namespace into C# applications. I'm not sure if that would completely or partly enable your using application events for this as is done in VB or not, but it's worth checking out. Failing that, this article has been around for some time and should help, if not completely solve, your problem. The code is VB but the principle is directly applicable to C#.

Yay! It works!
It took me a while to figure out how to put it all together though.

Yes, it solved my problem completely. I tried to convert that code to C# at first, but I was unsuccesful because of some compile errors I didn't know how to get around. I then compiled both the main VB.NET code and the test form into an assembly and referenced it from my application. Finally, I inherited from the test form and wrote a little extra C# code.

I'd love to, but I don't really know what classes I should start inspecting first
