The other keys are identical,even though traditionally the names of
special keys are printed on them in English. This is because Belgium
is predominantly bilingual (French-Dutch) and officially trilingual (a
third language,German,is spoken in the East Cantons).

所以MAJ印刷为SHIFT.例如,在Office中,带有SHIFT的快捷方式显示为SHIFT.在Infragistics控件中,它们显示为MAJ.这让我们的客户感到沮丧.

因此,在与Infragistics讨论后,他们声称这是一个Windows Api调用,它返回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调用不会返回SHIFT,如果它是正常的,那么Office如何才能正确显示它？

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
}

如果是Shiftkey,则扫描码为2752512(2a),并返回MAJ.

那么,我的问题是什么？

>为了“nl-BE”文化而归还MAJ是否正常？或者它是user32.dll中的错误？
>如果Office能够做到正确,那么Infragistics是否也能做到正确呢？
> Infragistics是否使用正确的user32.dll api调用？

为了完整性,我将粘贴Utilities类的完整代码.从Form下一次调用完成：

systemLocalizedString = Utilities.GetLocalizedShortcutString(shortcut);

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文件中没有找到MAJ,只有Shift(例如2a Shift).那么为什么user32.dll会返回MAJ？甚至更奇怪的是,当我复制.klc文件并将其安装为新键盘时,突然user32.dll确实为新安装的键盘返回Shift(虽然它是一个精确的副本).
