Permission Problems

11/25/2005 3:06:08 PM

I'm currently developing a WebPart reading (and later hopefully writing) an Excel file (using Microsoft.Office.Interop.Excel). When testing I get the following error message:

quote:
System.Security.SecurityException: Request for the permission of type System.Security.Permissions.SecurityPermission, mscorlib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 failed. ....

This is basically the code I'm running and the error occurs when executing line 5:

1 path = "C:\\Test.xls";
2 workbook = app.Workbooks.Open(path,Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
3 sheet = (Worksheet)workbook.ActiveSheet;
4 excelCell = (Range) sheet.get_Range("B2", "B2");
5 String test =  excelCell.Value2;

Any ideas???

Hello,

If you faced that problem with a hosting company then contact them to increase your site trust level and possibly refreshing the pool after that.

What's the stack trace of the exception? Does this scenario work outside of a WebPart, or do you get the same error?
