push char into Windows keyboard buffer

I don't know Visual C++ so I was planning to do it with Foxpro.

How could I [rogrammatically push key into the Windows buffer (so that
another app that's in focus would get it)?

Is it as simple as calling the right Win32API? Which one?

DECLARE INTEGER SendMessage IN user32;
INTEGER hWnd,;
INTEGER Msg,;
INTEGER wParam,;
INTEGER lParam

I lack expereince with Win32API.

Msg is an integer. How to use it?

ok I found an example:

SendMessage(hWnd, WM_KEYDOWN, VK_RETURN, 0);
SendMessage(hWnd, WM_KEYUP, VK_RETURN, 0);

What is the value of constant WM_KEYDOWN, WM_KEYUP, VK_RETURN,
VK_0...VK_9, VK_A...VK_Z?

Tbanks. I had problem getting these two to work. DO you have an example?
I tried:

sendmessage(wHandle, WM_KEYDOWN, asc("A"), 1)
sendmessage(wHandle, WM_KEYUP, asc("A"), 1)

No response on the target window.

Thanks. But I really like to know more about the WM_KEYDOWN and
WM_KEYUP... -_-
