Question

I am looking for a solution to programmatically hold a keyboard key down during some time (I don’t know how many time).

I think that if I send a WM_KEYDOWN message the key will be held down until WM_KEYUP is send, but I am not sure.

I would test it. But I need to go and I don’t have much time. I want to see if someone already tested this.

Here is an other question I posted, related to this one.
I want to make a virtual keyboard. Do I need to send WM_KEYDOWN to the current active window or HWND_BROADCAST?

Answer 1

No, because If you examine the messages sent when using the keyboard, you’ll see that the message are as follow:

WM_KEYDOWN
WM_KEYPRESS
WM_KEYUP

The WM_KEYPRESS message is sent every couple of ticks (depending on the keyboard configuration).
