Question

I try to use SaveAs() to save Excel spreadsheet data (with 8 sheets, some sheets with 15000 rows) but the SaveAS() never returns. If I remove some sheets it will success to save to hard disk file. Is there any way I could save the whole huge spreadsheet without hanging?

Thanks a lot.

///////// my c# code to save Excel data:
xlWorkBook.SaveAs(outFileName,
                  Excel.XlFileFormat.xlWorkbookNormal,
                  Type.Missing,
                  Type.Missing,
                  false,
                  false,
                  Excel.XlSaveAsAccessMode.xlExclusive,
                  false,
                  false,
                  Type.Missing,
                  Type.Missing,
                  Type.Missing);

xlWorkBook.Close(true, misValue, misValue);
xlApp.Quit();

Have you tried running it with xlApp.Visible = True to see if Excel is popping up any strange errors? You can also try xlApp.DisplayAlerts = false to stop any warnings/errors that might be popping up behind the running application (we’ve run into both of these problems before)
