SendMessage for keystroke is not working

[Guest poirepoisson]

Hi all

 

 

 

could you please tell me why this code does not work? It should simulate the pression of TAB and then arrow DOWN, but nothing happens. I´m sure I have the right handle to the window, because I can click with the mouse on some of its buttons.

 

 

 

SetForegroundWindow(hwndWindow);

 

SetActiveWindow(hwndWindow);

 

SetFocus(hwndWindow);

 

 

SendMessage(hwndWindow, WM_SETFOCUS, VK_TAB, 0); //tried also without

 

SendMessage(hwndWindow, WM_SETFOCUS, VK_TAB, 0); //these 2 messages

 

Sleep(500);

 

SendMessage(hwndWindow, WM_KEYDOWN, VK_TAB, 0);

 

SendMessage(hwndWindow, WM_KEYUP, VK_TAB, 0);

 

Sleep(1000);

 

SendMessage(hwndWindow, WM_KEYDOWN, VK_DOWN, 0);

 

SendMessage(hwndWindow, WM_KEYUP, VK_DOWN, 0);

 

 

 

 

Many thanks in advance
