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();
            }

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);
