Hi everyone

Im using the trial version of Flowchart.net, im trying to export my chart to visio file (*.vdx) using the visioExporter assembly as fllowes.

FlowChart fc = (FlowChart)Session["fcx"];
VisioExporter ve = new VisioExporter();
ve.CreateVisioGroups = true;
ve.Export(fc,"chart.vdx");

But it doesn work and doesn return any exception.

Any help is appreciated.
Bye

Hi,

Do you use the WebChart library ? At this time the import/export components work only with the Windows Forms control.

... or if you use the FlowChart.NET control there, make sure the VisioExport.vxt file is in the same folder where the assemblies are.

I am also testing the Visio Exporter as well.  My application is web based, but I have finished converting all the objects from WebChart to FlowChartX.  The diagram prints nicely on the web page.  I have added an Export button to create the Visio diagram.  Here is the code that I have in the function for the button:

Private Sub btnVisio_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnVisio.Click
       fc = CType(Me.Session.Item("fcx"), MindFusion.FlowChartX.FlowChart)
       Dim VisioFile As New MindFusion.Diagramming.Export.VisioExporter
       VisioFile.ExportTablesAsGroups = True
       VisioFile.CreateVisioGroups = True
       VisioFile.Export(fc, "c:\export\test.vdx")

End Sub

I don't get any errors when I click the button, but it seems that it never creates the file.  I have put the VisioExport.vxt in the web page's bin folder (where the FlowChart.Net.dll file resides) as well as the c:\export folder.  I have also tried just using "c:\export" instead of "c:\export\test.vdx" for the vdxPathName parameter for the export function. Is there anything else that I am missing?

Does the ASP.NET process have write access to that folder ?

I did change the permissions on the c:\export folder to allow ASPNET write permissions.  Still would not work.  I then added "everyone" write permissions in the folder.  I can successfully create .svg files, but still no luck with the Visio Exporter. 

Does the VisioExporter log any kind of error message at all?

Could you also take a look at the VisioExport.vxt properties - does the aspnetwp process have read access to that file ?

The VisioExport.vxt file has the <local>\ASPNET account with Change permissions in both c:\export and the \bin folder for the web application.

Ok, our developer traced through the Export method code and found there is some problem loading the template file while running in IIS. He will fix that in awhile.

ASP.NET seems to copy the Web application assemblies to a temporary path and runs it from there, at least in debug mode, so the VisioExporter cannot find the VisioExport.vxt file. We have added a TemplatePath property which you must set to the full path of the .vxt file, and the exporter works fine when the path is set explicitly. If you need to have the fix now, let me know for which version of the .NET runtime you need the flowchart assemblies.

If I could get the fix now, I'd appreciate it.  I'm running the 1.1 framework currently.
