ext_ConnectMode.ext_cm_UISetup, as shown in the following code. The remaining code in the OnConnection method will only execute if the following condition is true:

C#:

if(connectMode == ext_ConnectMode.ext_cm_UISetup)

VB:

If connectMode = ext_ConnectMode.ext_cm_UISetup Then

The first time the code runs, the code within the preceding if statement will execute, creating a menu item for the KeystrokeFinder Add-In in the Tools menu. Code examples that follow in this section are all contained within the preceding if statement; this is good information to know because it shows you how to navigate the VS object model to find something.

The following code uses _applicationObject to get a list of commands, which is a list of all the actions you can take with VS. As discussed earlier, _applicationObject is type DTE2 and serves as the parent object for accessing all functionality in VS.

C#:

Commands2 commands = (Commands2)_applicationObject.Commands;

VB:

Dim commands As Commands2 =

CType(_applicationObject.Commands, Commands2)

In the VS automation object model, a menu item is called a CommandBar. So, you get a reference to a CommandBars collection, again through _applicationObject, to reference the MenuBar, which is the main VS menu, assigned to menuBarCommandBar:

C#:

Microsoft.VisualStudio.CommandBars.CommandBar menuBarCommandBar = ((

Microsoft.VisualStudio.CommandBars.CommandBars) _applicationObject.CommandBars)["MenuBar"];

VB:

Dim commandBars As CommandBars = CType(_applicationObject.CommandBars, CommandBars)

Dim menuBarCommandBar As CommandBar = commandBars.Item("MenuBar")
