Creating the Visio custom menus and handling the click event from C# programs.This project requires that Visio application should run and it requires a default drawing to be open.

Introduction

There are several ways to handle the menus in the Microsoft Visio application, but there are no events generated when the user clicks the menu. The best way to handle the menus and menu event handling is through CommandBars. Most of the sites I went never had a solution. Some of the forums mentioned an idea of how to implement. I needed something quicker to find a solution. Then I got through CommandBars. Hope this article will help you in all aspects in handling the menu bar.

With this article, you can not only to handle the menus in Microsoft Visio, but also the menus in some other Microsoft applications. E.g.: Microsoft Word, Microsoft Excel, Microsoft Outlook, etc.

This article concentrates more on Microsoft Visio. In this article, I will show you how to create custom menus and how to handle menu click event handlers.

This demo needs 2 components to be added: those are Microsoft Office 11.0 Object Library, Microsoft Visio 11.0 Type Library.

Code:

This demo contains CustomMenu class which will take care of setting the custom menus, and deleting a custom menu from the standard menu bar of the Visio application.

Let us start with the using declaration:

using Visio=Microsoft.Office.Interop.Visio;

The above statement includes Microsoft Visio interop services.

Secondly, private variables declaration:

private Microsoft.Office.Core.CommandBars commandBars;
private Microsoft.Office.Core.CommandBar commandBar;
private Microsoft.Office.Core.CommandBarButton commandBarButton;

The above variables are use to hold the standard CommandBars of Microsoft Visio application.

private Visio.Application visioApplication;
object visioObject = Marshal.GetActiveObject("Visio.Application");
this.visioApplication = visioObject as Visio.Application;

The above statements holds the visio application reference.

To get the built in menus from the Visio application, the following statement will work:

Visio.UIObject uiObject = this.visioApplication.BuiltInMenus;

After adding the menu to the menu bar, it should be set to standard menu bar of the Visio application with the following statement:

this.visioApplication.ActiveWindow.Document.SetCustomMenus(uiObject);

To get the standard CommandBars of the Visio application, the following statement has to be executed:

commandBars= 
  (Microsoft.Office.Core.CommandBars) this.visioApplication.CommandBars;

Note:

*This demo requires that Visio application should be run, and it requires a default drawing to be open.

Conclusion:

CommandBars can be used for a lot of things: creating menu bars, tool bars, etc. I feel CommandBar is the best way to handle Microsoft applications in your code, and you can play with the applications. I hope you can make good use of this code in your own projects.
