Access to report file denied...

[JCruz063]

I need my website clients to be able to download a report. The report is created at run-time based on options the user selects, and displayed using a Crystal Reports viewer (duh!). I have a button that says "Download in PDF", which is supposed to export the report in PDF format to a temporary location on the server, upload it to the user, and then delete it.

The code that exports the report in PDF format to a temporary folder is the following:

[COLOR=green]// This is C# code...

// rpt is the report I created[/color]
rpt.ExportOptions.ExportFormatType =
    ExportFormatType.PortableDocFormat;
rpt.ExportOptions.ExportDestinationType = 
    ExportDestinationType.Diskfile;

DiskFileDestinationOptions dskOpt = [COLOR=blue]new[/color]
    DiskFileDestinationOptions();
[COLOR=green]// TempFldr is a directory in my web site[/color]
[b]dskOpt.DiskFileName = 
    [COLOR=blue]this[/color].MapPath("TempFldr\\MyReport.pdf");[/b]
rpt.ExportOptions.DestinationOptions =
    dskOpt;

rpt.Export();

When the code above runs, I get an error that says: "Access to report file denied. Another program may be using it."

I thought it was that ASP.NET didn't have the rights to create files, but (using IIS), I allowed all rights possible, (read, write, run scripts, etc) to all the files and folders in my web site, and I still get the same problem. Also, I changed the path where the temporary PDF is stored (see the line in bold in the code above), and I made it "C:\\MyReport" and, guess what! it works. Of course, I don't think is terribly exiting to save a temporary report to the C drive of my server so I came to you guys so you could help me save it to the \TempFldr instead.

Can anybody tell me what the source of my problem may be?

Thanks!
