User32 API calls in .NET
I'm currently planning out a project involving creating a shell replacement for Windows (based on Blackbox, bblean specifically). However I wish to leverage the power of .NET to do so. Many of the API calls I'll need are housed within the User32 library. I can of course use P/Invoke and create a static class to handle this for me. Ho...
User32's ShowWindow doesn't act as expected
I am using the ShowWindow method from User32 to hide a window (cmd.exe) from the user (mainly to prevent them from closing it). When the user opens the form, the process is started, and hid, then when the form is closing the process is killed. However, when the form is opened again, it doesn't hide the window (and sometimes doesn't the f...

Automated Clicking Problem
I am coding up a program for automated testing which randomly clicks an open application window using various User32.dll library calls.

Using SendMessage for Simulating User Mouse Clicks
I need to use SendMessage fro simulating user clicks in a target program as SendMessage blocks until the event that it triggers is finished processing.

How to get minimized window's RESTORED bounds?
It's easy to get the bounding rectangle for all the visible windows on a screen. It's also easy to tell if any window is iconic or not. But for minimized windows, the Top and Left is reported as -32000 from User32.GetWindowInfo.rcWindow. I've looked all through the API and can't find a call to return the bounds the window would restore...
