HOW TO：建立 Office 工具列

發行項
08/12/2011

這個範例會在 Microsoft Office Outlook 中建立工具列。這個含有兩個按鈕的工具列會顯示在應用程式的頂端。當您按一下按鈕時，程式碼就會顯示一則含有按鈕標題的訊息。

**適用於：**本主題中的資訊適用於下列應用程式的應用程式層級專案：InfoPath 2007、Outlook 2007、Project 2007 和 Visio 2007。如需詳細資訊，請參閱依 Office 應用程式和專案類型提供的功能。

雖然這是 Outlook 專屬範例，但是程式碼中建立工具列的部分，還是能用來建立以上所列之任何應用程式的工具列。

範例

Dim newToolBar As Office.CommandBar
Dim firstButton As Office.CommandBarButton
Dim secondButton As Office.CommandBarButton
Dim selectExplorers As Outlook.Explorers

Private Sub ThisAddIn_Startup(ByVal sender As Object, _
        ByVal e As System.EventArgs) Handles Me.Startup
    selectExplorers = Me.Application.Explorers()
    AddHandler selectExplorers.NewExplorer, AddressOf _
        Me.NewExplorer_Event
    AddToolbar()
End Sub

Private Sub NewExplorer_Event(ByVal new_Explorer _
    As Outlook.Explorer)
    new_Explorer.Activate()
    newToolBar = Nothing
    Call Me.AddToolbar()
End Sub

Private Sub AddToolbar()

    Dim button_1 As Office.CommandBarButton
    Dim button_2 As Office.CommandBarButton
    If newToolBar Is Nothing Then
        Dim cmdBars As Office.CommandBars = _
            Me.Application.ActiveExplorer().CommandBars
        newToolBar = cmdBars.Add("NewToolBar", _
            Office.MsoBarPosition.msoBarTop, False, True)
    End If
    Try
        button_1 = CType(newToolBar.Controls.Add(1),  _
            Office.CommandBarButton)
        With button_1
            .Style = Office.MsoButtonStyle.msoButtonCaption
            .Caption = "Button 1"

        newToolBar.Visible = True
    Catch ex As Exception
        MsgBox(ex.Message)
    End Try

        }
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);

}

private void ButtonClick(Office.CommandBarButton ctrl,
        ref bool cancel)
{
    MessageBox.Show("You clicked: " + ctrl.Caption);
}

穩固程式設計

請在類別層級宣告您的命令列變數，不要在呼叫變數的方法內進行宣告。如此便可確保在應用程式執行期間，命令列變數都會保留在範圍內。否則，記憶體回收會移除項目，而且您的事件處理常式不會執行。
