我发送钥匙时遇到了一些麻烦。似乎什么时候我想发送密钥它不起作用。
我正在考虑像T这样的sending alphabetic characters从例子开始聊天，但是如果我把它写入枚举，那么每当我使用它时都没有任何反应。有任何想法吗？

您的代码没有发送击键。它正在发送一条消息，表示密钥已更改而未实际发送输入。如果目标窗口仅查看消息并忽略实际的键状态，则这可能有效。 DirectX应用程序通常会关注实际的键盘状态，并会忽略您发送的消息。
而是使用SendInput API将键注入输入流。在此级别注入的输入将通过正常输入处理并像真正的键盘输入一样工作。根据目标应用程序，您可能需要在KEYBDINPUT结构中设置扫描码，而不仅仅是虚拟键。这可能是DX应用程序。
有关更多信息，请参阅Simulating Input中的MSDN's keyboard input overview部分。
似乎这个问题提出了很多观点，所以这是我之前做过的解决方案（我收集了一个站点的输入，并将其设置为枚举以便于使用。）：
