在ASP.NET中调用Visio2003

可以参照

ASP.NET 2.0 Visio Custom Control

主要思想如下：

        protected override void RenderContents(HtmlTextWriter writer)
        {
            try
            {
                StringBuilder sb = new StringBuilder();
                sb.Append("<object classid=clsid:279D6C9A-652E-4833-BEFC-312CA8887857 id=vviewer ");
                sb.Append("codebase=http://download.microsoft.com/download/4/5/2/452f8090-413f-408f-83c0-edd66db786ee/vviewer.exe Width = " + Width.Value.ToString() + " Height = " + Height.Value.ToString() + " > ");
                sb.Append("<param name=SRC value=" + FilePath.ToString() + "> ");
                sb.Append("<param name=HighQualityRender value=1> ");
                sb.Append("<param name=BackColor value=#000000> ");
                sb.Append("<param name=PageColor value=#000000> ");
                sb.Append("<param name=PageVisible value=1> ");
                sb.Append("<param name=AlertsEnabled value=1> ");
                sb.Append("<param name=ContextMenuEnabled value=1> ");
                sb.Append("<param name=GridVisible value=1> ");
                sb.Append("<param name=PropertyDialogEnabled value=1> ");
                sb.Append("<param name=ScrollbarsVisible value=1> ");
                sb.Append("<param name=ToolbarVisible value=1> ");
                sb.Append("<param name=CurrentPageIndex value=1> ");
                sb.Append("<param name=Zoom value=-1> ");
                sb.Append("</object>");

                writer.RenderBeginTag(HtmlTextWriterTag.Div);
                writer.Write(sb.ToString());
                writer.RenderEndTag();
            }
            catch
            {
                // with no properties set, this will render "Display Visio Control" in a
                // a box on the page
                writer.RenderBeginTag(HtmlTextWriterTag.Div);
                writer.Write("Display Visio Control");
                writer.RenderEndTag();
            }  // end try-catch
        }   // end RenderContents

客户端需要至少安装visio viewer2003
