You could use our Windows Forms component, build a diagram model (using same API as ASP.NET's Diagram class) and export it with VisioExporter. If you don't want to use the Diagram control at all, you will have to build the Visio XML yourself by its file format specification (http://msdn.microsoft.com/en-us/library/ms426602(v=office.12).aspx) or use another library.

Using the XmlDocument API you could move the XML content saved by the diagram to a child element of the Visio document after exporting:

VisioExporter vex = new VisioExporter();
vex.ExportInvisibleItems = false;
vex.ExportTablesAsGroups = true;
vex.DynamicsOff = true;
vex.Export(diagram, sfd.FileName);

var visioDoc = new XmlDocument();
visioDoc.Load(sfd.FileName);

var diagDoc = new XmlDocument();
diagram.SaveToXml(diagDoc);

var diagElement = visioDoc.ImportNode(
	diagDoc.DocumentElement, true);
visioDoc.DocumentElement.AppendChild(diagElement);
visioDoc.Save(sfd.FileName);
 

and later load like this

var visioDoc = new XmlDocument();
visioDoc.Load(fileName);
var diagElement = visioDoc.GetElementsByTagName("Diagram")[0];
var diagDoc = new XmlDocument();
diagElement = diagDoc.ImportNode(diagElement, true);
diagDoc.AppendChild(diagElement);
diagram.LoadFromXml(diagDoc); 

I hope that helps,

sfd.FileName is the file path for exported Visio file selected via Windows Forms SaveFileDialog. diagram is a Diagram instance.

It's the path for the exported Visio VDX file. Then the diagram's XML is appended to it via intermediate XmlDocument, without actually saving the diagram to a separate file.

You can use the diagramming.dll and export.visio.dll from ASP.NET version in your WinForms application if all you need is exporting to Visio, just add references to them to your project. The WinForms and ASP.NET versions include the same model and import/export assemblies, they only differ in the view-specific assemblies that build upon the respective UI platform, e.g. diagramming.winforms.dll and diagramming.webforms.dll.
