SHIFT快捷键显示为区域性的MAJ“；nl BE”；当它应该是SHIFT(C#.NET)时

经过与Infrastics的长时间讨论，在我的区域性"nl BE"中，带有SHIFT的ShortCuts显示为MAJ。首先，文化"nl BE"和AZERTY有点奇怪。阅读http://en.wikipedia.org/wiki/AZERTY如果想了解更多。重要的报价是：

其他键是相同的，尽管传统上特殊的钥匙用英文印在上面。这是因为比利时主要是双语（法语-荷兰语）和官方三语（a第三种语言，德语，在东部各州使用）。

所以MAJ被打印为SHIFT。例如，在Office中，带有SHIFT的快捷方式显示为SHIFT。然而，在Infrastics控件中，它们显示为MAJE。这让我们的客户感到沮丧。

因此，在与Infrastics讨论后，他们声称这是一个Windows Api调用，返回的是MAJ而不是SHIFT。我从他们那里得到了一个展示行为的示例项目。所以现在我的问题是，为什么Windows Api调用不返回SHIFT，如果它是正常的，那么Office如何正确显示它？

获取密钥文本的代码是：

NativeWindowMethods.GetKeyNameText((int)scanCode, sb, 256);

和

class NativeWindowMethods
{
    #region MapVirtualKey
    [DllImport("user32.dll")]
    internal static extern int MapVirtualKey(uint uCode, uint uMapType);
    #endregion //MapVirtualKey
    #region GetKeyNameText
    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    internal static extern int GetKeyNameText(
        int lParam, 
        [MarshalAs(UnmanagedType.LPWStr), Out]System.Text.StringBuilder str, 
        int size);
    #endregion //GetKeyNameText
}

在Shiftkey的情况下，扫描代码为2752512（2a），返回MAJ。

那么，我的问题是什么？

• MAJ被退回文化"nl BE"是正常的吗？或者是user32.dll中的错误
• 如果Office做对了，难道不应该由Infrastics来做对吗
• Infrasgistics是否使用正确的user32.dll api调用

为了完整起见，我将粘贴Utilities类的完整代码。从表单完成下一次调用：

systemLocalizedString=Utilities。GetLocalizedShortcutString（快捷方式）；

使用快捷键=ShiftF12。调用后，systemLocalizedString等于"MAJ+F12"。

更新：在Hans Passant的帮助下，我下载了Microsoft Keyboard Layout Creator并导出了我当前的键盘布局。在.klc文件中找不到MAJ，只有Shift（例如2a Shift）。那么，为什么user32.dll返回MAJ呢？更奇怪的是，当我复制.klc文件并将其作为新键盘安装时，突然user32.dll会为新安装的键盘返回Shift（尽管它是一个精确的副本）。
