I want send message to edit window, activated and begin input text.
invoke SendMessage,[hwnd_EditWin], WM_LBUTTONDOWN,1,0

But I see only caret in edit window and text not input.
When I click mouse to edit window, then text begin input from keyboard.

I try this, but not help:
invoke SetActiveWindow,[hwnd_EditWin]
invoke EnableWindow,[hwnd_EditWin],1
invoke SetFocus,[hwnd_EditWin]
