写文本到剪切板：

    CString source;
    //put your text in source
    if(OpenClipboard())
    {
        HGLOBAL clipbuffer;
        char * buffer;
        EmptyClipboard();
        clipbuffer = GlobalAlloc(GMEM_DDESHARE, source.GetLength()+1);
        buffer = (char*)GlobalLock(clipbuffer);
        strcpy(buffer, LPCSTR(source));
        GlobalUnlock(clipbuffer);
        SetClipboardData(CF_TEXT,clipbuffer);
        CloseClipboard();
    }
从剪切板读文本
    char * buffer;
    if(OpenClipboard())
    {

        buffer = (char*)GetClipboardData(CF_TEXT);
        //do something with buffer here
        //before it goes out of scope

    }

    CloseClipboard();
