Programmatically add shapes to a Visio document
You can add shapes to a Microsoft Office Visio document by retrieving the masters from a stencil and dropping the shapes on the active page.
For more information, see the VBA reference documentation for the Microsoft.Office.Interop.Visio.Documents.Add method, Microsoft.Office.Interop.Visio.Application.ActivePage property, and Microsoft.Office.Interop.Visio.Page.Drop method.
Add shapes to a Visio Document
To add shapes to a Visio document
With a document active, retrieve the masters from the Documents.Masters collection and drop the shapes on the active document. You can retrieve a master by using the index or master name.
The following code example creates a blank Visio document, and then opens it with the Basic Shapes stencil docked. The code then retrieves several shapes and drops them on the active page.
this.Application.Documents.Add(""); Visio.Documents visioDocs = this.Application.Documents; Visio.Document visioStencil = visioDocs.OpenEx("Basic Shapes.vss", (short)Microsoft.Office.Interop.Visio.VisOpenSaveArgs.visOpenDocked); Visio.Page visioPage = this.Application.ActivePage; Visio.Master visioRectMaster = visioStencil.Masters.get_ItemU(@"Rectangle"); Visio.Shape visioRectShape = visioPage.Drop(visioRectMaster, 4.25, 5.5); visioRectShape.Text = @"Rectangle text."; Visio.Master visioStarMaster = visioStencil.Masters.get_ItemU(@"5-Point Star 7"); Visio.Shape visioStarShape = visioPage.Drop(visioStarMaster, 2.0, 5.5); visioStarShape.Text = @"Star text."; Visio.Master visioHexagonMaster = visioStencil.Masters.get_ItemU(@"Hexagon"); Visio.Shape visioHexagonShape = visioPage.Drop(visioHexagonMaster, 7.0, 5.5); visioHexagonShape.Text = @"Hexagon text.";
