Gewusst wie: Verfügbarmachen eines Add-Ins im Menü "Extras" (Visual Basic)

Aktualisiert: November 2007

When you create an add-in by using the Add-In Wizard and select the option to display it as a command, the command is on the Tools menu by default. If you skip this option when you create the add-in, however, you can simply run the Add-In Wizard again, check that option, and then copy your existing code to the new add-in.

If doing this is not possible, though, the following procedure accomplishes the same thing.

Hinweis:
The dialog boxes and menu commands you see might differ from those described in Help depending on your active settings or edition. These procedures were developed with the General Development Settings active. To change your settings, choose Import and ExportSettings on the Tools menu. For more information, see Visual Studio-Einstellungen.

To add a menu command to an existing add-in

1. In the Connect class of the add-in, add Implements IDTCommandTarget.

   This gives you access to the IDTCommandTarget commands interface which is necessary for creating commands.

2. In the OnConnection procedure, add the following:

   Imports System
   Imports Microsoft.VisualStudio.CommandBars
   Imports Extensibility
   Imports EnvDTE
   Imports EnvDTE80
   
   _applicationObject = CType(application, DTE2)
   _addInInstance = CType(addInInst, AddIn)
   If connectMode = ext_ConnectMode.ext_cm_UISetup Then
       Dim commands As Commands2 = CType(_applicationObject.Commands, _
         Commands2)
       Dim toolsMenuName As String
       Try
           Dim resourceManager As System.Resources.ResourceManager = _
           New System.Resources.ResourceManager _
            ("MyAddin1.CommandBar", System.Reflection.Assembly. _
            GetExecutingAssembly())
   
           Dim cultureInfo As System.Globalization.CultureInfo = New _
            System.Globalization.CultureInfo(_applicationObject. _
            LocaleID)
           toolsMenuName = resourceManager.GetString(String.Concat _
             (cultureInfo.TwoLetterISOLanguageName, "Tools"))
   
       Catch e As Exception
           toolsMenuName = "Tools"
       End Try
   
       Dim commandBars As CommandBars = _
         CType(_applicationObject.CommandBars, CommandBars)
       Dim menuBarCommandBar As CommandBar = _
         commandBars.Item("MenuBar")
   
       Dim toolsControl As CommandBarControl = _
         menuBarCommandBar.Controls.Item(toolsMenuName)
       Dim toolsPopup As CommandBarPopup = CType(toolsControl, _
         CommandBarPopup)
   
       Try
           Dim command As Command = _
             commands.AddNamedCommand2(_addInInstance, "MyAddin1", _
             "MyAddin1", "Executes the command for MyAddin1", True, _
             59, Nothing, CType(vsCommandStatus. _
             vsCommandStatusSupported, Integer) + _
             CType(vsCommandStatus.vsCommandStatusEnabled,  _
             Integer), vsCommandStyle.vsCommandStylePictAndText, _
             vsCommandControlType.vsCommandControlTypeButton)
   
          command.AddControl(toolsPopup.CommandBar, 1)
       Catch argumentException As System.ArgumentException
       End Try
   End If
   

   This code executes when the add-in is loaded ("connected") in Visual Studio. It determines if the add-in was loaded with a ext_ConnectMode value of ext_cm_UISetup. This means the add-in was started for the first time since being installed. If this is true, then a command is created for it on the Tools menu by using the AddNamedCommand method. For more information, see Gewusst wie: Hinzufügen und Ändern von Befehlen.

3. Add the following two procedures to the Connect class.

   The QueryStatus method is called when the command's availability is updated. The Exec method is called when the command is invoked.

   Public Sub QueryStatus(ByVal commandName As String,  _
     ByVal neededText As vsCommandStatusTextWanted, ByRef status As _
     vsCommandStatus, ByRef commandText As Object) Implements _
     IDTCommandTarget.QueryStatus
       If neededText = vsCommandStatusTextWanted. _
         vsCommandStatusTextWantedNone Then
           If commandName = "MyAddin1.Connect.MyAddin1" Then
               status = CType(vsCommandStatus.vsCommandStatusEnabled _
                 + vsCommandStatus.vsCommandStatusSupported, _
                 vsCommandStatus)
           Else
               status = vsCommandStatus.vsCommandStatusUnsupported
           End If
       End If
   End Sub
   
   Public Sub Exec(ByVal commandName As String, ByVal executeOption _
     As vsCommandExecOption, ByRef varIn As Object, ByRef varOut As _
     Object, ByRef handled As Boolean) Implements IDTCommandTarget.Exec
       handled = False
       If executeOption = vsCommandExecOption. _
         vsCommandExecOptionDoDefault Then
           If commandName = "MyAddin1.Connect.MyAddin1" Then
               handled = True
               Exit Sub
           End If
       End If
   End Sub
   

   Each time you implement IDTCommandTarget, you must add these two procedures. A quick way to do it is to select IDTCommandTarget in the Class Name drop-down box at the top-left corner of the editor. Select each procedure in turn from the Method Name drop-down box in the top-right corner. This creates the necessary empty procedures with the correct parameters to which you can then add code.

   The Exec procedure is called when a user clicks your menu command, so insert code there that you want to execute at that time.
