Reviewing OnConnection Generated Code

You know that the purpose of the OnConnection method is to help initialize the Add-In, and you’ve seen the parameters populated by VS and what each parameter means. Listing 13-2 shows the code generated by VS after the Add-In Project Wizard completes. It reflects the result of choosing to have a command bar UI, shown in Figure 13-5. Code comments were omitted to place more focus on the code itself.

Listing 13-2 The OnConnection method

C#:

public void OnConnection(

object application, ext_ConnectMode connectMode, object addInInst, ref Array custom)

{

_applicationObject = (DTE2)application; _addInInstance = (AddIn)addInInst; if(connectMode == ext_ConnectMode.ext_cm_UISetup)

{

object []contextGUIDS = new object[] { }; Commands2 commands =

(Commands2)_applicationObject.Commands; string toolsMenuName = "Tools";

Microsoft.VisualStudio.CommandBars.CommandBar menuBarCommandBar = ((

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

CommandBarControl toolsControl = menuBarCommandBar.Controls[toolsMenuName];

CommandBarPopup toolsPopup = (CommandBarPopup)toolsControl;

try

{

Command command = commands.AddNamedCommand2( _addInInstance, "KeystrokeFinder", "KeystrokeFinder",

"Executes the command for KeystrokeFinder", true, 59, ref contextGUIDS, (int)vsCommandStatus

.vsCommandStatusSupported+

(int)vsCommandStatus.vsCommandStatusEnabled,
