I need to press "ALT" and " Y" at the same time, and
I use SendMessage(frm1.hwnd, WM_KEYDOWN, &H59, 0)
,but it doesn't work. Can anyone tell me what's wrong...
Hello. I'm not sure what your usage scenario is but have you instead looked into using SendKeys? This would look something like System.Windows.Forms.SendKeys.Send(%Y). Check out the following link for more information
