Dear Sirs,

I do not manage to use the ExportVDX method, it seems that I do not well understood what it request as first argument flowChartDoc ?!?

My following c# example throw an InvalidCastException with no explicit message...

Could someone drive me to the right path ?

FcxVisioExportLib.VisioExporter vx = new FcxVisioExportLib.VisioExporter();
vx.ExportVDX(this.axFlowChart1, @"C:\Test.vdx");

Thank you in advance for your help.

Best Regards

Hi,

The following should work; GetOcx() returns the IDispatch pointer represented by the .NET wrapper class:

vx.ExportVDX(axFlowChart1.GetOcx(), @"C:\Test.vdx");

For .NET applications better use this control, it has all FlowchartX features implemented as a pure .NET class library:

I hope that helps,
Stoyan

Hi,

Thank you very much, it works like that...

I agree with you for the .net components, but unfortunately my clients just bought the ActiveX version and they are not ready to pay for another version...

Thanks

Best Regards

Hi,

If they just bought it and don't actually need the ActiveX control, we can exchange their license for the .NET control for no additional cost, to save you from the torture that COM interop is Smiley Otherwise they can get a discount for additional licenses.

Hi Stoyan,

It would be very nice if they can change their license with the .net version...

I have some doubt about it anyway :

I already developed 70% of their application, will it have a lot of things to change from the ocx version ?

And another thing : their application will have to exchange some diagram from an external application (which is not mine) saved with the axFlowChart1.SaveToFile() and axFlowChart1.LoadFromFile() methods...

Will it still work if they are generated by an activex version and loaded with the .net version ?

Thank you.

Best Regards

Hi,

It will work only if using SavetoXml and LoadFromXml. The APIs are very different though, so I suppose you'll stick to the ActiveX control.

Hi,

Thank you for your answer...

As I have no control on the other application and that it is not exporting with xml method, like you said I am condemned to the ActiveX Control...

Thank you very much anyway...

Best Regards
