I'm trying to get a file uploader to work on my website. It works fine on my local pc. I listed the following code for each page below. I tried to change the path in the code by I'm not sure of the complete home directory path where my webpage is kept.


default.asp

<form name="frmSend" method="POST" enctype="multipart/form-data" action="updatedb.asp">
<input name=attach1 type=file size=35><br>
<input name=submit type=submit value="Submit">
</form>

well there you are then!


use server.mappath in the appropriate place to set the path.

next answer is, No I'm not going to scan through that code to find it [bugeyed]
