把文本放置到剪接板上：
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();
}

从剪接板上获取文本：
char * buffer;
if(OpenClipboard())
{
    buffer = (char*)GetClipboardData(CF_TEXT);
    //do something with buffer here
    //before it goes out of scope
}
CloseClipboard();
