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. SetForegroundWindow(NextHWnd) & Bring it up ShowWindow(NextHWnd,3) & Show window maximized ENDIF IF lCloseIt & Close Window.If the target window is owned by another process and has a caption, GetWindowText retrieves the window caption text. 5 *ENDIF IF cWinText $ UPPER(lpString) & Found text within Window Caption. * IF LEN(lpString) > 2 * ? lpString * WAIT '' TIMEOUT.
