限制输入内容 :

响应消息OnChar

void CEnglishEdit::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags)

{

    // TODO:  在此添加消息处理程序代码和/或调用默认值

    if ((nChar >=  && nChar <= ) ||       //+,-./ 0~9

        (nChar >= && nChar <= ) ||        //A~Z

        (nChar >= && nChar <= ) ||       //a~z

        nChar ==  || nChar ==  ||       //";\"

        nChar ==  || nChar ==   ||       //" SP"

        nChar == 01 || nChar == 03 ||       //ctrl + a c

        nChar == 24 || nChar == 22          //ctrl + x v

        )

    {

        CEdit::OnChar(nChar, nRepCnt, nFlags);

    }

    else

    {

        return;

    }

}

代码中红色部分是实现 复制粘贴全选剪切的功能;

进过实践发现重写 PreTranslateMessage()  不能实现复制粘贴剪切的功能,可以实现全选功能,根据最上边Ctrl组合键ASCII码 来添加自己需要的功能.
