Win32's FindWindow() can find a window having the title of "Untitled - Notepad", but what if I just want to find a Notepad window but don't know whether it is "try.bat - Notepad" or some other file name on the title bar?

My application redraws the screen every time the mouse moves. I have not at all handled WM_KEYDOWN and I noticed that when I press shift or ctrl, it does not redraw on mouse mouse, nor does it seem to really do anything else. What could cause such a thing? If I press any other key like Z or X it does exactly what it should. Thanks ...

Inspired by Scripting Twitter with cURL, I'm trying to make a command line app in C, used to update my Twitter status. I'm not really sure how curl works in this case...

I'm trying to wrap my head around getting user input from a joystick/mouse, which doesn't seem all that complicated, but I've run across this simple showstopper: calling joyGetNumDevs() gives me an unresolved external symbol error.

Hi, How would one retrieve the handle of the control that currently has focus ?

I'm working on a C++ application in Visual Studio (non-MFC) and was surprised to find that I can't add a PNG image to a dialog in the designer which seems a little backward as I can in most other IDEs that I've used. So either a) there is something I'm missing or b) there is a way to do it with code. I'm hoping that it's a but b would be...

I get WM_NCCREATE, WM_NCCALCSIZE, WM_CREATE, WM_SIZE, WM_MOVE and WM_SHOWWINDOW. After that nothing except WM_DESTROY when the parent is destroyed. ...
