$ pad = new COM("pad.application") or die("Unable to instantiate pad ");
echo "Loaded Notepad, version {$ pad ->Version}\n";
//bring it to front
$ pad ->Visible = 1;
//open an empty document
$ pad ->Documents->Add();
//do some weird stuff
$ pad ->Selection->TypeText("This is a test...");
$ pad ->Documents[1]->SaveAs("Sample test.doc");
