Hi.

I need to integrate my program into a different program created by someone else. Basically I need to draw a tiny image in the top left corner on the other application that shows some statistics from my application which will run in the background.

The target application is created in unmanaged c++. I've seen a video of this, so I know it's possible. I've tried a couple of things, one is to create a panel and simply set it's parents to the target application's window handle, however this has yielded undesired effects. I need to actually draw on the other application so that mouse events still reach the target application.

A managed solution is desirable, but I'm no stranger to platform invoke.

Any ideas?
