Using Excel Interop via VS.NET 2005 to create and save a new Excelworksheet.. please help!
 

Guys,

Sorry for crossing multiple groups but I am at my wits end... Please
help!

Below is my code in C# (VS.NET 2005.. I have tried every combo I can
think of. Every "SaveAs"
call results in the strange HRESULT 0x800A03EC error. I have verified
that the
folder path exists and that "Everyone" has Full Control on it. I have
also
tried Missing.Value in place of nulls. :(

Thanx!

J'son

CODE:

//create initial excel sheet
GC.Collect(); //clear out any earlier instances
Excel._Application application = new Excel.Application();
application.Visible = false;

Excel._Workbook workbook = application.Workbooks.Add(Missing.Value);
Excel._Worksheet sheet = (Excel._Worksheet)workbook.ActiveSheet;

//format the titles
DataColumnCollection columns = results.Tables[0].Columns;
for (int i = 0; i < columns.Count; i++)
{
string rangeHeader = ColumnLetter(i + 1) + "1";
Excel.Range range = (Excel.Range)sheet.get_Range(rangeHeader,
rangeHeader);

range.Font.Bold = true;
range.VerticalAlignment = Excel.XlVAlign.xlVAlignCenter;
range.Value2 = columns[i].ColumnName;
range.EntireColumn.AutoFit();
}

//save the workbook for now -- ERROR HITS HERE!

application.ActiveWorkbook.SaveAs(_filePath, Excel.XlFileFormat.
xlWorkbookNormal, null, null, false, false, Excel.XlSaveAsAccessMode.
xlNoChange, false, false, null, null, null);
workbook.Close(null, null, null);
application.Quit();

Thanx!
