[RESOLVED] launching excel from asp.net app

[DirtyHowi]

i have an app that outputs a gridview to excel spreadsheet and adds a couple of rows for accounting.

i'm trying to launch the spreadsheet after its saved off, using

            excelApp.ActiveWorkbook.SaveAs(filename);
            excelApp.ActiveWorkbook.Saved = true;
            excelApp.Quit();
            var si= new ProcessStartInfo {FileName = filename, UseShellExecute = true}; //hits here and crashes
            Process.Start(si);

it hits the marked line and crashes that it cant find the file, its automatically saving it to the documents folder on my local machine, and i cant seem to get it to save elsewhere (i have a data directory in the project i use for the other file types) that i would like to save to if possible, but it seems that if you have office installed it don't like it. i could always copy the file from documents to the datastore, but that's a pain in the backside.

so how do i launch excel application using the file i just saved off to show to the bean crunchers? VB examples will work as well, i can translate
