我想将拉丁语键盘翻译成另一个键盘，如维吾尔语等。有一个维吾尔语键盘，但键的编码是如此复杂，以至于普通PC用户不能轻易键入维吾尔语。
所以我的目标是为这个问题创建一个软件解决方案，例如中文输入系统。在该系统中，您可以从各种键盘输入中文字符。这是一种聪明的解决方案，所以每个人都可以毫无问题地使用它。
所以我的目标是我想编写一个Windows服务应用程序，它捕获每个KeyDown-Strike（仅字母表）并将按下的键转换为目标（Unicode）字母并再次使用此翻译的字母模拟键击。结果，目标字母表将显示在光标点中。在结束时，我的应用程序从KEYDOWN按下
中丢弃/停止原始密钥这样就不会再显示了。
例如：
0xFEBD，然后发送回光标点。到目前为止，第1步和第2步工作正常。我的问题是，在我捕获按键事件后，我无法丢弃/取消/停止此次击键的最后一次按键事件。
我不确定我的想法是否良好/有效，足以实现我的想法。现在我只是在尝试。也许你有更好的想法，你可以建议我。这是我的代码：
