构建一个VISIO插件，通过创建矩形并在其中包含文本来显示有关形状选择的相关数据

Question

Visio.Page visioPage = this.Application.ActivePage;
//Create a rectangle
Visio.Shape details = visioPage.DrawRectangle(45, 45, 45, 45);
Visio.Selection selection = Window.Selection;
            foreach (dynamic item in selection)
            {
                Visio.Shape shp = item as Visio.Shape;
                if (shp != null)
                {  
                   //Dropping Rectangle on to the page
                   visioPage.Drop(details, 50, 50);
                }
 }

尝试上面的代码在Application_SelectionChanged事件内的visio上创建一个矩形。但是，无法在Visio上看到矩形。请指出这里的错误或任何有关相同的指针。

Answer 1

您的矩形似乎没有宽度和高度。可能这是原因吗？ DrawRectangle接受x1，y1，x2，y2坐标。

Answer 2

缺少Visio模板。

 Visio.Documents visioDocs = this.Application.Documents;
    // Get Basic Shapes Stencil
     Visio.Document visioStencil = visioDocs.OpenEx("Basic Shapes.vss",
                (short)Microsoft.Office.Interop.Visio.VisOpenSaveArgs.visOpenDocked);
    //Get Rectangle Shape
    Visio.Master visioRectMaster = visioStencil.Masters.get_ItemU(@"Rectangle");
    // Add Shape to Page
    Visio.Shape visioRectShape = visioPage.Drop(visioRectMaster, rectX, rectY);
    visioRectShape.NameU = "ShapeName";
