我想可以用API CopyFileEx()<br>BOOL CopyFileEx(<br> LPCTSTR lpExistingFileName, // name of existing file<br> LPCTSTR lpNewFileName, // name of new file<br> LPPROGRESS_ROUTINE lpProgressRoutine, // callback function<br> LPVOID lpData, // callback parameter<br> LPBOOL pbCancel, // cancel status<br> DWORD dwCopyFlags // copy options<br>);<br>
