I have a little file upload page that I have been able to use to successfully upload files to the C: drive of LocalHost (my machine). I need to be able to upload to a network drive from the intranet server. On the line: dirs = Directory.GetDirectories(currentDir) I get "Access to the path "\\les-net\les\Special Projects\ATSPDF" is denied." How do I get the GetDirectories command to user my user ID and password when it tries to hit the network drive. The browser has a login where the UserID and Password are captured and stored in session variables that information is available. How do I cause GetDirectories to use that info?
If you need more information I have included the relevant HTML, VB.NET code and the Error message I get.
This is what I try:
In aspx page:
<FORM id=Form1 method=post enctype="multipart/form-data" runat="server">
<FONT face=verdana>Select File to Upload:</FONT> <INPUT
id=uploadedFile type=file name=uploadedFile runat="server">
<INPUT id=upload type=button value=Upload name=upload runat="server">
</FORM>
In code behind:
