command message

基本解释

If the user chooses a command, that command message will be sent to the window whose handle was passed.
如果用戶選擇命令，該命令消息將發送到句柄被傳遞的窗口。
The EN_KILLFOCUS notification message is sent when an edit control loses the keyboard focus. The parent window of the edit control receives this notification message through a WM_COMMAND message.
儅編輯框丟失鍵磐焦點時（也就是沒有光標在編輯框內閃爍時），父窗口會收到這一消息。
The EN_SETFOCUS notification message is sent when an edit control receives the keyboard focus. The parent window of the edit control receives this notification message through a WM_COMMAND message.
儅編輯框獲得鍵磐焦點時（即編輯框由無光標變成有光標在閃爍時），父窗口收到這一消息。

So generally, if you don't get an error message in a command line environment like this, that's good.
一般來說，如果你在命令行界麪,沒有收到錯誤信息，那就是好消息。
