Applies to: desktop apps only
Reverses or restores the meaning of the left and right mouse buttons.
Syntax
BOOL WINAPI SwapMouseButton( __in BOOL fSwap );
Parameters
- fSwap [in]
-
Type: BOOL
If this parameter is TRUE, the left button generates right-button messages and the right button generates left-button messages. If this parameter is FALSE, the buttons are restored to their original meanings.
Return value
Type: BOOL
If the meaning of the mouse buttons was reversed previously, before the function was called, the return value is nonzero.
If the meaning of the mouse buttons was not reversed, the return value is zero.
Remarks
Button swapping is provided as a convenience to people who use the mouse with their left hands. The SwapMouseButton function is usually called by Control Panel only. Although an application is free to call the function, the mouse is a shared resource and reversing the meaning of its buttons affects all applications.

I'm trying to run this from CMD (the command prompt)
RUNDLL32.EXE user32.dll,SwapMouseButton *
Where the asterisk is here is where the argument should go. I already ran it without an argument and it swapped my left and right mouse buttons (seems TRUE is the default entry for the boolean argument). Now I want to undo it.
However I've tried each of these for passing FALSE in the argument, and none have worked (none set my mouse buttons back to normal).

FALSE
"false"

Please help me pass the argument as needed. Thanks in advance.
