Create a New Diagram

VSTO

VSTO lets you program with Microsoft Visio files. To create a new diagram:

1. Create a Visio application object.
2. Make the application object invisible.
3. Create an empty diagram.
4. Add shapes from Visio masters (stencils).

5. Save the file as VDX.

       Visio.Application vdxApp = null;
       Visio.Document vdxDoc = null;
       try
       {
           //Create Visio Application Object
           vdxApp = Application;
   
           //Make Visio Application Invisible
           vdxApp.Visible = false;
   
           //Create a new diagram
           vdxDoc = vdxApp.Documents.Add("Drawing.vsd");
   
           //Load Visio Stencil
           Visio.Documents visioDocs = vdxApp.Documents;
           //-----------//
           Visio.Document visioStencil = visioDocs.OpenEx("sample.vss",
               (short)Microsoft.Office.Interop.Visio.VisOpenSaveArgs.visOpenHidden);
   
           //Set active page
           Visio.Page visioPage = vdxApp.ActivePage;
   
           //Add a new rectangle shape
           Visio.Master visioRectMaster = visioStencil.Masters.get_ItemU(@"Rectangle");
           Visio.Shape visioRectShape = visioPage.Drop(visioRectMaster, 4.25, 5.5);
           visioRectShape.Text = @"Rectangle text.";
   
           //Add a new star shape
           Visio.Master visioStarMaster = visioStencil.Masters.get_ItemU(@"Star 7");
           Visio.Shape visioStarShape = visioPage.Drop(visioStarMaster, 2.0, 5.5);
           visioStarShape.Text = @"Star text.";
   
           //Add a new hexagon shape
           Visio.Master visioHexagonMaster = visioStencil.Masters.get_ItemU(@"Hexagon");
           Visio.Shape visioHexagonShape = visioPage.Drop(visioHexagonMaster, 7.0, 5.5);
           visioHexagonShape.Text = @"Hexagon text.";
   
           //Save diagram as VDX
           vdxDoc.SaveAs("Drawing1.vdx");
       }
       catch (Exception ex)
       {
           Console.WriteLine(ex.Message);
       }
       finally
       {
           //Close active document and quit
           vdxDoc.Close();
           vdxApp.Quit();
       }
   

Aspose.Email

When programming with Aspose.Diagram, you do not need Microsoft Visio on the machine, and you can work independently of Microsoft Office Automation. To create a new diagram:

1. Create an empty diagram.
2. Add shapes from Visio masters (stencils).

3. Save the file as VDX.

       string visioStencil ="sample.vss";
       // Create a new diagram
       Diagram diagram = new Diagram(visioStencil);
   
       //Add a new rectangle shape
       long shapeId = diagram.AddShape(
           4.25, 5.5, 2, 1, @"Rectangle", 0);
       Shape shape = diagram.Pages[0].Shapes.GetShape(shapeId);
       shape.Text.Value.Add(new Txt(@"Rectangle text."));
   
       //Add a new star shape
       shapeId = diagram.AddShape(
           2.0, 5.5, 2, 2, @"Star 7", 0);
       shape = diagram.Pages[0].Shapes.GetShape(shapeId);
       shape.Text.Value.Add(new Txt(@"Star text."));
   
      //Add a new hexagon shape
     shapeId = diagram.AddShape(
       7.0, 5.5, 2, 2, @"Hexagon", 0);
   

   shape = diagram.Pages[0].Shapes.GetShape(shapeId);
   shape.Text.Value.Add(new Txt(@"Hexagon text."));

       //Save the new diagram
       diagram.Save("Drawing1.vdx", SaveFileFormat.VDX);
