" | 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() { $Handle = GUIGetProp($GUI, "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", "iIII", $Handle, 160, 777, 1337); }
