Basic Visio 2003 C# Interaction, drawingControl

Question

I am dabbling in a little drawing automation with Visio 2003. However, I am having a problem taking what MSDN says and incorporating it into my code. I am probably making a very newbie mistake. However, after days of searching the internet I have yet to implement a solution.

I am trying to simply open a stencil from a tbClick. The MSDN site tells me to use DrawingControl.Src to open the stencil. However, when I apply DrawingControl to the code and compile I get this error: An object reference is required for the nonstatic field, method, or property 'VisOcx.IDrawingCopntrol.Src.get'(CS0120). Below is a snippet of code that shows the namespace resources and the function I am trying to implement.

I am open to any and all suggestions about the code as well.

//namespace
using System;
using System.Collections.Generic;
using System.Drawing;
using System.Windows.Forms;
using System.Diagnostics;   
using System.Runtime.Serialization;
using System.Runtime.InteropServices;
using Visio1 = Microsoft.Office.Interop.Visio;
using Visio2 = VisOcx;

//function
void Qed2_elevation_stencil_tbClick(object sender, EventArgs e)
  {

   try
   {
    Visio2.DrawingControl.Src = "C:\\Drawing.vsd";
   }
   catch (Exception ex)
   {
    MessageBox.Show(ex.Message);
   }

      return;
  }

Answer 1

You are trying to access the drawing control statically, when it needs to be instantiated for use. Here's a walkthrough that should help.

Answer 2

I think I am much closer to making this code work. I am now getting the error, "No overload for 'Qed2_elevation_stencil_tbClick' matches delegate 'System.EventHandler' (CSO123). Below is the updated code. Thank you in advance for anyone who is willing to help.

// 
// qed2_elevation_stencil_tb
// 
this.qed2_elevation_stencil_tb.ToolTipText = "QED2 Front Elevation";
this.qed2_elevation_stencil_tb.Click += new    
system.EventHandler(this.Qed2_elevation_stencil_tbClick);

using System;
using System.Configuration;
using System.Collections.Generic;
using System.Collections;
using System.Data;
using System.Drawing;
using System.Windows.Forms;
using System.Diagnostics;   
using System.Runtime.Serialization;
using System.Runtime.InteropServices;
using System.IO;


using Visio1 = Microsoft.Office.Interop.Visio;
using Visio2 = VisOcx;
using Visio3 = AxMicrosoft.Office.Interop.VisOcx;

public partial class MainForm : Form
{


 public MainForm()
 {
  //
  // The InitializeComponent() call is required for Windows Forms   designer support.
  //
  InitializeComponent();

  //
  // TODO: Add constructor code after the InitializeComponent() call.
  //
 }

 private Visio1.Application VisApp = null;
 private Visio1.Page   VisPage = null;  
 private Visio1.Document  VisDocument = null;
 private Visio1.Documents VisDocuments = null;
 private Visio1.Window  VisWindow = null;
 private Visio1.Document  VisStencil = null;

private void Qed2_elevation_stencil_tbClick(ref Visio1.Documents visDocuments)

 {
  string stencilPath = System.IO.Path.Combine(@"C:\\Documents and Settings\\MGPF50\\My Documents\\Visio Stencils", @"Front Elevation Stencil.vss");

        try
        {
            VisStencil = visDocuments.OpenEx(stencilPath,
                (short)Visio1.VisOpenSaveArgs.visOpenRO
                + (short)Visio1.VisOpenSaveArgs.visOpenHidden
                + (short)Visio1.VisOpenSaveArgs.visOpenMinimized
                + (short)Visio1.VisOpenSaveArgs.visOpenNoWorkspace);
        }
        catch (COMException exp)
        {
            MessageBox.Show("Error Loading Stencil: " + stencilPath + exp.Message);
            throw exp;
        }
 }
