会解析这个WM_CHAR消息，然后就会调用OnChar()函数，将发送的字符作为参数传入这个函数。
在MFC的对话框中,映射了WM_CHAR和WM_KEYDOWN消息响应函数后,还是不能响应OnKeyDown和OnChar。 (2)原因 因为MFC在进行设计的时候,这两个消息被对话框上的控件截获了,不能到达这两个消息响应函数,对于OnKeyDown来说,只要把对话框 上的控件都删除了,就可以接收到WM_KEYDOWN消息,但是还是接收不到WM_CHAR消息。
这样,程序就能正确地调用onKeyDown和onChar这两个函数了,且onKeyDown()在onCchar()之前处理的。这样就能在对话框中响应WM_CHAR、WM_KEYDOWM消息了,注意在发送WM_CHAR时,实际发送了三个消息 即WM_CHAR WM_KEYDOWM WM_KEYUP 所以,如果你有如下代码: ...

The WM_UNICHAR message is designed to send or post Unicode characters to ANSI windows. It is equivalent to the WM_CHAR message, but uses Unicode Transformation Format-32 encoding (UTF-32), whereas the WM_CHAR message uses UTF-16.备注 This member function is called by the framework to ...
