HOW TO：將自訂圖示加入至工具列和功能表項目

發行項
08/12/2011

這個範例會將圖示加入至 Microsoft Office Outlook 之自訂功能表上的命令列按鈕中。此圖示會包含在專案資源內。如需專案資源的詳細資訊，請參閱Adding and Editing Resources (Visual C#) 和 HOW TO：加入或移除資源。

**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，但是程式碼中將圖示加入至命令列按鈕的部分，還是可以用來將圖示加入至以上所列任何應用程式中的命令列按鈕。

若要加入自訂圖示

請將程式碼加入至 Outlook 專案的 ThisAddIn.vb 或 ThisAddIn.cs 檔，以便建立表示自訂功能表和功能表命令的 CommandBarPopup 及 CommandBarButton 控制項。這個程式碼會查看功能表是否存在。如果存在，這個程式碼就會移除功能表。然後，它會加入新的功能表。

Private MenuBar As Office.CommandBar

建立一個名為 ConvertImage 的新類別。這個類別會使用 System.Forms.Axhost，將 Image 檔轉換成可套用至功能表項目的影像類型。

<Global.System.Security.Permissions.PermissionSetAttribute _
 (Global.System.Security.Permissions.SecurityAction.Demand, Name:="FullTrust")> _
Public Class ConvertImage
    Inherits System.Windows.Forms.AxHost
    Public Sub New()
        MyBase.New("59EE46BA-677D-4d20-BF10-8D8067CB8B32")
    End Sub

    Public Shared Function Convert(ByVal Image _
        As System.Drawing.Image) As stdole.IPictureDisp
        Convert = GetIPictureFromPicture(Image)
    End Function
End Class

sealed public class ConvertImage : System.Windows.Forms.AxHost
{
    private ConvertImage()
        : base(null)
    {
    }

    public static stdole.IPictureDisp Convert
        (System.Drawing.Image image)
    {
        return (stdole.IPictureDisp)System.
            Windows.Forms.AxHost
            .GetIPictureDispFromPicture(image);
    }
}

加入方法，以便將圖示檔轉換成 Image 檔，方法是將它加入至 ImageList。這個程式碼會將 Image 檔傳送至您所建立的 ConvertImage.Convert 方法，然後將檔案傳回呼叫端。

Private Function getImage() As stdole.IPictureDisp
    Dim tempImage As stdole.IPictureDisp = Nothing
    Try
        Dim newIcon As System.Drawing.Icon = My.Resources.Icon1
        Dim newImageList As New System.Windows.Forms.ImageList
        newImageList.Images.Add(newIcon)
        tempImage = ConvertImage.Convert(newImageList.Images(0))
    Catch ex As Exception
        MsgBox(ex.Message)
    End Try
    Return tempImage
End Function

private stdole.IPictureDisp getImage()
{
    stdole.IPictureDisp tempImage = null;
    try
    {
        System.Drawing.Icon newIcon =
            Properties.Resources.Icon1;

        System.Windows.Forms.ImageList newImageList = 
            new System.Windows.Forms.ImageList();
        newImageList.Images.Add(newIcon);
        tempImage = ConvertImage.Convert(newImageList.Images[0]);
    }
    catch (Exception ex)
    {
        System.Windows.Forms.MessageBox.Show(ex.Message);
    }
    return tempImage;
}
