Hi. I would like to know how to determine when the user presses, say, ''z'' *while* holding down one of the virtual keys, say Ctrl. For example // Ctrl + Z I can use either OnKeyDown(...) and/or OnChar(...) to determine *either* Ctrl or z, but not both. I am trying to implement an "undo" feature. Thanks, Kuphryn

I think you need to keep track of the state of ctrl.
There''s also a OnKeyUp - set a flag when ctrl goes down, unset it when ctrl goes up.

- The trade-off between price and quality does not exist in Japan. Rather, the idea that high quality brings on cost reduction is widely accepted.-- Tajima & Matsubara

Thanks.

I tried that, but it did not work either.

My personal solution would be to use GetAsyncKeyState with VK_CONTROL while you process the VK_Z to determine whether or not Ctrl (or shift or anything else for that matter) is being pressed simultaneously.
