I don't know, if it is a Aspose.Cells or an IIS problem (perhaps I'm the problem ;-)). But anyway. Hope to get a solution. Here is my problem:
I have an typical IIS installation under c:\inetpub\wwwroot ... If I open a workbook located on c: (it doesn't matter if it is stored directly on c: or an underlying path of wwwroot, etc.), it works fine.
But know, I have to open a workbook from a network share linked to the webserver. I tried to solve it by passing the whole path like "Z:\Test\Test.xls". I also thought about the virtual path feature from IIS, but I could not imagine how it should work in this situation. Everytime I get the exception that file could not be found. Opening workbooks from local drive d: also doesn't work.
When I get this run, then I think, that the workbook.save thing will also work !?!
