you must get the control id first. to get control id, you can use FindWindow and GetDlgCtrlID()... then: HWND hWnd = FindWindow(....); ::SendMessage( hWnd, WM_COMMAND, nButtonID, 0 );

Yeah I understood it was for example. if you have handle to that program you can use of this code for get handle to other controls on that forum and then send your message to a control.

for(CWnd* pWnd = needsto handle; pWnd;pWnd = pWnd ->GetNextWindow())
{
pWnd ->GetWindowTextW(str);
}

Send WM_COMMAND message to the parent of the button, and set the WPARAM and LPARAM as follows wparam = MAKEWPARAM( , BN_CLICKED ); lParam = (LPARAM);
