Hi there,

I am trying to export a chart using the Excel11 object from C#. I can
properly open workbooks and read cells, but calling Export() on the Chart
object throws a COMException

Exception: System.Runtime.InteropServices.COMException (0x800A03EC):
Exception from HRESULT: 0x800A03EC.
at Excel._Chart.Export(String Filename, Object FilterName, Object
Interactive)
at MBCCS.LeParc.Importer.Importer.GetImageInfoFromWor ksheet(Worksheet
worksheet) in d:\source\leparc\importer\importer.cs:line 211

The line causing this is:

tempChart.Chart.Export(filename, "JPEG", Missing.Value);

The JPEG filter is registered.

I am trying to export a picture in excel. What I am doing is creating a new
chart, copying the picture to the chart, then exporting the chart. The
Excel.exe process is running under the ASPNET account.

Any ideas would be greatly appreciated.

Thanks,

Steven
