Question

背景：我正在使用C＃在VS2010中开发Outlook 2007加载项。我正在做的具体事情是将菜单项添加到与电子邮件关联的上下文菜单中。我使用以下代码执行此操作：

private void ThisAddIn_Startup(object sender, System.EventArgs e)
{
   Application.ItemContextMenuDisplay += Application_ItemContextMenuDisplay;
}

private void ThisAddIn_Shutdown(object sender, System.EventArgs e)
{
}

private void Application_ItemContextMenuDisplay(Office.CommandBar commandBar, Outlook.Selection selection)
{
   var cmdButtonCallContact = (Office.CommandBarButton)commandBar.Controls.Add(Office.MsoControlType.msoControlButton, 1, System.Reflection.Missing.Value, 6, System.Reflection.Missing.Value);

   cmdButtonCallContact.Caption = "&Foo";
   //cmdButtonCallContact.Picture = ?
   cmdButtonCallContact.Click += cmdButtonCopy_Click;
}

private void cmdButtonCopy_Click(Office.CommandBarButton ctrl, ref bool canceldefault)
{
   System.Windows.Forms.MessageBox.Show("Bar");
}

问题：似乎无法设置图片。 Msdn示例依赖于我没有的AxHost转换函数。是否有直接的方法将图像或BitMap设置为图片？

感谢。

Answer 1

如果您想要自定义图片，则必须依靠AxHost方法（ see MSDN reference ）或PictureDispConverter这是另一种方法created by Microsoft在OleCreatePictureIndirect。

如果您想使用内置图标，只需设置FaceId即可。下载Office Icons Gallery以查看Office 2007 FaceId值。

以下代码使用System.Drawing.Bitmap（存储为资源）并将其转换为可分配给Office.CommandBarButton.Picture的图像

private Office.CommandBarButton buttonOne;
void createbutton()
{
    Office.CommandBar newMenuBar = Inspector.CommandBars.Add("EAD", Office.MsoBarPosition.msoBarTop, false, true);
    buttonOne = (Office.CommandBarButton)newMenuBar.Controls.Add(Office.MsoControlType.msoControlButton, 1, missing, missing, true);buttonOne.Caption = "Ansari";
    buttonOne.Style = Office.MsoButtonStyle.msoButtonIconAndWrapCaptionBelow;                   

    buttonOne.Picture = getImage();
    //Register send event handler
    buttonOne.Click += buttonOne_Click;
    newMenuBar.Visible = true;
}
void buttonOne_Click(Office.CommandBarButton Ctrl, ref bool CancelDefault)
{
    MessageBox.Show("Hi");
}
private stdole.IPictureDisp getImage()
{
    stdole.IPictureDisp tempImage = null;
    try
    {
        System.Drawing.Bitmap 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;
}
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);
    }
}

注意：在资源中添加名称为Icon1的图像。

Answer 3

仅供参考，如果您想将任何办公室内置图片应用于您的按钮（查看here中的图片库），您只需拨打GetImageMso()方法即可。

CommandBarButton.Picture = Application.CommandBars.GetImageMso("ImageMSO", 16, 16);

这是使用FaceID属性的另一种方法。
