For exmaple,

chart.ChartWizard(range5, XlChartType.xl3DColumn, Missing.Value,
XlRowCol.xlRows, 0, 0, True, "Chart", _"Category Type", "Value Type")

the above code worked well in excel 2k3, but always got exception in excel
2k7.

The exception was,

Unhandled Exception: System.Runtime.InteropServices.COMException
(0x80020005): T
ype mismatch. (Exception from HRESULT: 0x80020005 (DISP_E_TYPEMISMATCH))
