Hi everyone,
I need to test for a Right MouseButton click in a procedure that does not
have any Mouse Events as arguments.
in order to allow or prevent editing depending on which MouseButton was
pressed.
Using the following code:
RetVal := GetKeyState(VK_RBUTTON);
The function returns -127 the first time it's called, -128 the second time,
followed by -127, -128, etc.. the return value alternates between -127
& -128 for each call. Can anyone explain this?
I can test like this:
bNoEdit := Abs(RetVal) in [127..128];
But I'm sure there is a better way...
Any ideas?
Best regards,
Dave Atkin
