“Hiding” System Cursor

Question

• I\'ve trie

Answer 1

I found a good workaround for hiding system cursor temporarily that doesn't involve screwing around with setsystemcursor().

SetSystemCursor() is dangerous, because if the app crashes or otherwise throws a bug, the cursor will be changed permanently until the next reboot.

Instead, I implemented a transparent window over the whole desktop, and that window hides the cursor when needed. The method to use is ShowCursor from Win32.

The transparent window can be something like this: http://www.codeproject.com/Articles/12597/OSD-window-with-animation-effect-in-C

[DllImport("user32.dll")]
static extern int ShowCursor(bool bShow);

ShowCursor(false);

Answer 2

One application can't affect another applications cursor. You'd have to write a mouse driver of some sort in order to do this.
