VB/WinAPI, finding my window's taskbar button

finding my window's taskbar button

Paul Smi #1 / 3	finding my window's taskbar button Hi everyone, Does anyone know of a VB6 way of finding the top and left values of my current window's taskbar button when minimised? I've got height and width OK, and I want to write graphics to (on top of?) my taskbar button when my app is minimised. I don't mind using the API, but GetWindowPlacement returns ptMinposition x=3000, y=3000 which clearly is not the real position.

One way or another you'd have to inject code in the Shell process space, and then use the Toolbar API to get that information. Because the taskbar buttons are actually buttons in a Toolbar control. The easiest way to get code to execute in the shell process is probably to put it in an COM component, and then call the SHLoadInProc API. Then you'd have to use some IPC mechanism to get the information back to your app. The problem is that on some Windows versions (I don't know if it's the same on all), the Toolbar buttons are ownerdrawn, and you can probably not get the button text with a TB_GETBUTTONTEXT message. So I don't know how you can determine exactly which button belongs to your window. Maybe the lParam member of the TBBUTTONINFO structure contains something interesting, like the window handle.

Thanks a lot for the pointers. (I confess I don't have a clue what you're on about, but then what's the documentation for? :-) I'll starting digging in the ground you've marked out for me.
