Hi,

I think it is feasible to use Flowchart.NET and the Pdf/Visio exporters from a VB.NET console application. Just add references to the flowchart.net assemblies to your application. Import the MindFusion.FlowChartX namespace and create a FlowChart instance like this:

dim fc as new FlowChart()

Then you can use methods such as CreateBox and CreateArrow to generate the diagram programmatically. You might use some of the automatic layouts to arrange the diagram, and finally create a VisioExporter or PdfExporter instance and call its Export method to create the VDX/PDF file.

I hope that helps,
Stoyan
