I'm using VS .net 2003 and OfficeXP for Excel automation.
Saving the Excel sheet results in
System.Runtime.InteropServices.COMException: HRESULT: 0x800A03EC
the command is as follow
oBook.SaveAs(TargetPath,oMissing,oMissing,oMissing ,oMissing,oMissing,Excel.XlSaveAsAccessMode.xlNoCh ange, oMissing,oMissing,oMissing,oMissing,oMissing);
