System.Runtime.InteropServices.COMException: Invalid file name. 1

Hi

We are attempting to deploy some CR XI reports on our intranet in ASPX pages using VB .NET.

We currently have a problem that when we debug the page we receive the error:

System.Runtime.InteropServices.COMException: Invalid file name.

Its driving me mad, i cannot seem to find a solution.

Any help would be much appreciated
Thanks

Hi

I am having this exact same problem with my asp.net page.

The really anoying thing for me is it works on my development server and not on my deployment server. Both servers are running the same version of windows and have the same options installed. I am hoping that in the time since you posted this you might have come accross a solution.

Also I have the crystal reports portion packaged in a dll and i can use a simple application with the exact same paramaters using the exact same function call and it will work. It is only when i go to create the report from asp.net that the problem occurs.

In case this is helpfull to any one here is the stack trace that it gives me.

[COMException (0x800001fb): Invalid file name.]

Any help would be greatly appreciated.

Thank you in advance

Hi

My problem was caused by the ASP .NET worker process not having access to the windows temp directory.

Try giving everyone full access to the windows temp directory.

Hope it helps

Thanks

Thank you very much for your prompt reply. That solved my problem. When i first got this problem i thought of permissions, but i added permissions to everywhere i thought it would need them and it still wasn't working. I would have never thought of adding to the windows temp directory for this one.

Thanks again
