hi all,
i have a XML document manage.xml as follow:

<?xml version = "1.0"?>
<MANAGE>
<USER >
<USERNAME>aa</USERNAME>
<PASSWORD>aa</PASSWORD>

</USER>
</MANAGE>

i use DOM to insert one more USER like this:
<?xml version = "1.0"?>
<MANAGE>
<USER >
<USERNAME>bb</USERNAME>
<PASSWORD>bb</PASSWORD>

</USER>
<USER >
<USERNAME>aa</USERNAME>
<PASSWORD>aa</PASSWORD>

</USER>
</MANAGE>

After that, i use Save method to save it (xmldoc.save("manage.xml") ) but i got an error : permission deny!

i want to save it to the file 'manage.xml', what can i do?

please help!
Thanks.
