Dear Mr.Rushme,
Thks for your reply, as u said, i creeated a folder called
c:\user\syed.rahim\mm.cfg, and run the following code, i want to
find the saving path of the file, i mean application storage
i.e. trace(docRoot.nativePath);
Alert.show(docRoot.nativePath);
in some case i want to use trace for debugging, like certain
function is getting fire or not? but the trace or alert is not
working, basically i want to display a message and debug..
code is:
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
applicationComplete="handleApplicationComplete(event)"
frameRate="60"
visible="false"
autoExit="true">
<mx:Style source="styles/styles.css"/>
<mx:Script>
