Simulating a Ctrl-V keystroke in Win32 (C or C++) using SendInput
This short example program simulates pressing Ctrl-V on the keyboard (the Windows shortcut for “Paste”) once every second. It’s a modified version of an earlier example I posted on keystroke simulation using the Win32 SendInput function. What’s different this time … Continue reading
How a console application can set the size of its window
This is an example of a Win32 console application that sets the size of the window it’s running in. When you run it, it sets the size of the console window to 640 x 400 pixels. It actually seems to … Continue reading
