Examples
// Create the Design Window $Window = GUICreate("Window", "Test GUI", 640, 482, 0, 0); // Show the Design Window GUILoad( $Window ); // Create the GUI objects $b1 = GUICreate("Button", $Window, "Send", 8, 8); // Add a link GUILink($b1, "Click", 'Send();'); // Create the GUI msgFilter GUIMsgFilter($Window, 'myMsgFilter($HWND, $MSG, $WParam, $LParam);'); // Keep the GUI running as long as long as the window is open While ( GUIStatus( $Window ) ) DoEvents( ); // When you create a msgfilter 4 variables are automatically created for you // $HWND // $MSG // $WPARAM // $LPARAM // All them names should be familiar to you Function myMsgFilter($HWND, $MSG, $WParam, $LParam) { println("HWND: " . $HWND . " | MSG: " . $MSG . " | WParam: " . $WParam . " | LParam: " . $LParam); return 0; // If you return HIGHER than 0 the msgfilter will be removed } // The button click goes here this will simply just be something to test out the msgFilter Function Send() { my $Handle = GUIGetProp($Window, "Handle"); // Get the HWND of our window // Send a message to the window containing 2 unique numbers 777 and 1337 // Just to see if they appear in the filter DLLCall("user32.dll", "PostMessage", "Int32", "tItt", "Ansi", $Handle, 160, 777, 1337); }
