{
bool ReturnValue=false;
try
{
ExcelTempObject.ActiveWorkbook.Save();
                                     ExcelTempObject.ActiveWorkbook.Saved=true;
 ExcelTempObject.ActiveWorkbook.Close(false,null,null);
          ExcelTempObject.UserControl=false;
ExcelTempObject.Quit();
ExcelTempObject=null;
System.GC.Collect();
ReturnValue=true; }
catch(System.Exception ex)
{
ExcelTempObject.ActiveWorkbook.Saved=false;
ReturnValue=false;
_ErrorMessageString=ex.Message;
}
                           finally
                           {
