/ to the buffer, including the null character. / the string is as long or longer than the buffer, the string is truncated and terminated with a null character. Type: LPTSTR )The buffer that will receive the text. Type: HWND )A handle to the window or control containing the text. However, GetWindowText cannot retrieve the text of a control in another / control, the text of the control is copied. / Copies the text of the specified window's title bar (if it has one) into a buffer. To retrieve the text of a possibly unresponsive control in the same process, use SendMessageTimeout with a WM_GETTEXT message instead. To retrieve the text of a control in another process, send a WM_GETTEXT message directly instead of calling GetWindowText. However, if the target window is not responding and it belongs to the calling application, GetWindowText will cause the calling application to become unresponsive. It allows applications to call GetWindowText without becoming unresponsive if the process that owns the target window is not responding. If the window does not have a caption, the return value is a null string. I had to look the function up in the header file to determine this.If the target window is owned by another process and has a caption, GetWindowText retrieves the window caption text. Replace "GetNextWindow" in your code with "GetWindow" and it will work. GetNextWindow() is just a C pre-processor macro which wraps GetWindow(). MSDN seems to think that it's a valid user32.dll function.MSDN is leaving out one crucial bit of information. It errors out on the final DLLCall() with stating that it's 'unable to use the DLL file', so I don't know.
MsgBox(0x40, "Next window handle", $HWnd)
$Response = DLLCall($DLL, "HWnd", "GetNextWindow", "HWnd", $HWnd, "Int", $GW_HWNDNEXT) $Response = DLLCall($DLL, "Int", "GetWindowText", "HWnd", $HWnd, "Str", $WinText, "Int", 80) $Response = DLLCall($DLL, "HWnd", "GetTopWindow", "HWnd", "")
Find the handle of the topmost window in the Z order
