Hi,

This morning I installed the Visio Exporter control in Delphi 2005. When calling ExportVDX(myFlowChartXCtrl, 'c:\test.vdx') an EOleException is raised stating "No such interface supported".

I checked if FcxVisioExport.vxt is in the same path as the executable, and it is.

What could be causing the problem here, and how can I fix this?

I checked the type library, and it says (amongst other things):

// PASTLWTR : 1.2
// File generated on 14.4.2006 7:05:43 from Type Library described below.

// ************************************************************************  //
// Type Lib: C:\WINDOWS\system32\FlowChartPro.dll (1)
// LIBID: {69ECBBD3-5C2A-4A84-ABEC-23937DBF1B54}
// LCID: 0


So I am using the pro version as far as I can tell. I do however have both versions installed on the same machine.

Ill try unregister the non-pro version, see if that makes a difference.

This isthe only code in VisioExporter.Export() that can throw the exception

// QI for IFlowChart interface of passed DISPATCH
hr = lpFlowChartX->QueryInterface( __uuidof(FXChart::IFlowChart),(void**) &pChart);

if FAILED(hr)
  throw _com_error(hr);

If the Delphi IDispatch wrapper for the FlowChart class does not implement the raw IFlowChart interface, the QueryInterface call above will fail. If any member of the wrapper class gives you access to the internal raw IFlowChart or IUnknown pointer, try passing it to the exporter instead of the Delphi object.

Btw, the same goes for the Visio importer, ofcourse.
