Outlook加载项、RibbonType Microsoft.Outlook.Explorer和Microsoft.Outlook.Mail.Read

Question

我有一个Outlook2010外接程序编码在.NET 4.0/VS.NET2010，C#。该加载项扩展了功能区=>，它将具有4个RibbonButtons的RibbonTab添加到(RibbonType属性设置为) Microsoft.Outlook.Explorer和Microsoft.Outlook.Mail.Read。

现在，如果用户单击其中一个RibbonButtons，我如何确定用户是否单击了添加到Microsoft.Outlook.Explorer OR Microsoft.Outlook.Mail.Read中的按钮

Answer 1

一种选择是创建(2)个具有共享功能库的功能区。调用共享库时，可以传递单击的功能区操作的上下文。

不过，更好的选择是检查应用程序的ActiveWindow属性，以通过ThisAddin.Application.ActiveWindow()确定用户所处的上下文。

 var windowType = Globals.ThisAddin.Application.ActiveWindow();
 if (windowType is Outlook.Explorer)
 {
     Outlook.Explorer exp = type as Outlook.Explorer;
     // you have an explorer context
 }
 else if (windowType is Outlook.Inspector)
 {
     Outlook.Inspector exp = type as Outlook.Inspector;
     // you have an inspector context
 }

SilverNinja的提议给我指明了一个方向。最后，我的代码是：

                // get active Window
            object activeWindow = Globals.ThisAddIn.Application.ActiveWindow();
            if (activeWindow is Microsoft.Office.Interop.Outlook.Explorer)
            {
                // its an explorer window
                Outlook.Explorer explorer = Globals.ThisAddIn.Application.ActiveExplorer();
                Outlook.Selection selection = explorer.Selection;
                for (int i = 0; i < selection.Count; i++)
                {
                    if (selection[i + 1] is Outlook.MailItem)
                    {
                        Outlook.MailItem mailItem = selection[i + 1] as Outlook.MailItem;
                        CreateFormOrForm(mailItem);
                    }
                    else
                    {
                        Logging.Logging.Log.Debug("One or more of the selected items are not of type mail message..!");
                        System.Windows.Forms.MessageBox.Show("One or more of the selected items are not of type mail message..");
                    }
                }
            }
            if (activeWindow is Microsoft.Office.Interop.Outlook.Inspector)
            {
                // its an inspector window
                Outlook.Inspector inspector = Globals.ThisAddIn.Application.ActiveInspector();
                Outlook.MailItem mailItem = inspector.CurrentItem as Outlook.MailItem;
                CreateFormOrForm(mailItem);
            }

也许这对其他人有帮助。
