Send virtual keystrokes to SDL+OpenGL

SDL Development

Hi,

I have a question:

Is there any way to send virtual keystrokes to an SDL (+ OpenGL) application through Windows API? Keybd_event doesn’t work.
But one thing i’ve noticed: With the Screen Keyboard (Windows 7) I can send keystrokes. Does somebody know how the screen keyboard works?

Thank you,

Hi,

according to MSDN documentation keyb_event as been superceeded by SendInput:

http://msdn.microsoft.com/en-us/library/ms646304(VS.85).aspx
http://msdn.microsoft.com/en-us/library/ms646310(VS.85).aspx

Another way could be by using SendMessage with WM_KEYDOWN?

Please note that since Windows Vista, there are more security constraints to
whom you are allowed
to send a message. This might be the problem you are facing.

Since Windows Vista, Microsoft changed the security rules to send messages
across applications.On Thu, Jan 28, 2010 at 4:11 PM, xdstyla wrote:
