Excel automation
Hi Zino,
I'm automating Excel from asp.net application on window2000. the application work fine on the developpement machine but not on the production server. when the runtime hit the second line of code: Dim xl As New Excel.Application Dim wb As Excel.Workbook = xl.Workbooks.Open("file.xls") it throw this error: "System.InvalidCastException: QueryInterface for interface Excel._Application failed" Excel is not designed to be run on a server in this manner. If you search the Microsoft KB for 'Excel Server' you should find some information about the (many) issues. Regards Stephen Bullen Microsoft MVP - Excel www.oaltd.co.uk |
