[RESOLVED] Error Reading Text File From Client PC

[ARPRINCE]

I have the code below. On my web page, I have a textbox and a
button. User enters the filename and path (ex. c:\test.txt) on the textbox and clicks on the button to process the file.

If I run it on the machine hosting the site, I have no errors.
However, when I run it on a client PC, I get an error. It's not
reading the file entered into the textbox.

Am I missing anything here? Why would it not read the text file in the client PC?

TIA
