Disable Save Dialog in Excel.Application (Delphi)

You can try using the following code to disable the dialog when saving an xls file using Excel.Application in Delphi:

ExcelApp.DisplayAlerts := False;
ExcelApp.ActiveWorkbook.SaveAs(FileName, xlExcel8);
ExcelApp.DisplayAlerts := True;

Note that you need to set 'DisplayAlerts' to 'False' before saving the file, and then set it back to 'True' afterwards. Also, make sure that you are using the correct file format ('xlExcel8' in this example) for your xls file.
