The Problem.

When I instantiate the UltraWingGrid.ExcelExport as shown below:

 If e.Tool.Key = "Exportar a Excel" Then

            Dim HojaExcel As New UltraGridExcelExporter

            HojaExcel.Export(Me.UltraGrid1, "c:\pais.xls")

            Process.Start("c:\pais.xls")

        End If

and run the program the following errors message displayed:

System.ArgumentException was unhandled by user code

  Message=Parameter is not valid.

  Source=System.Drawing
