推荐答案

问题尚不清楚，但是我可以通过键号"猜测您的意思是原始键标识符(该标识符先于键被识别为状态键，字符键等)，称为"扫描代码".您可以将其作为CWnd::OnKeyDown的参数nFlags的低字节来获取；请参阅:

另请参见: http://en.wikipedia.org/wiki/Scan_code [

The question is not clear, but I can guess by "key number" you mean a raw key identifier (which comes into play before a key is recognized as a status key, character key, etc.), which is called "scan code". You can get it as lower byte of the parameter nFlags of CWnd::OnKeyDown; please see:

http://msdn.microsoft.com/en-us/library/983st27a%28v=vs.100%29.aspx[^].

See also: http://en.wikipedia.org/wiki/Scan_code[^].

You can extract scan code from nFlags like this:

byte scanCode = nFlags & 0xFF;
