I am designing a custom module in DotNetNuke using visual studio 2005 (VB). Users would be able to upload some files in different formats like .txt .jpeg .pdf and ... from the module and it works fine using the following code: 

FileUpload1.SaveAs(Server.MapPath("Portals\0\R226.txt"))

I also need to give them the option to open these files when they want and look at them or download them. I am using the following code which is working perfect when I run it on my local computer but when I upload the code to the server, it doesn't work. I appreciate for any recommendation. To make the code simple, I am using a specified file instead of using variables.

System.Diagnostics.Process.Start(Server.MapPath("Portals\0\R226.txt"))

it gives me the following error:

A critical error has occurred.
The system cannot find the file specified

Thanks,

Thanks Chris for replying.

I usually check it as the host user and I just checked with other users and it is the same. Since it works locally and not on the server, I think something is wrong with the path I am using however I expect that MapPath can find the right path.

Thanks again Chris,

Ali

Thanks Steve for your nice comment but My proble hasn't been solved yet.

The vb code I am using to open the file is "C:\Inetpub\wwwroot\rnlvn.com\wwwroot\DesktopModules\MyModule\MyVBCode.ascx.vb"

The file I am trying to open is "C:\Inetpub\wwwroot\rnlvn.com\wwwroot\Portals\0\R226.txt"

The line of Code I am using to open the file is: "System.Diagnostics.Process.Start(Server.MapPath("Portals\0\R226.txt")

Is there any idea why the file can not be opened and I keet getting this error that "The system cannot find the file specified" ?

Thanks
