(转)Rapi 使用

{
    CFile oldFile;
    oldFile.Open(strFileNamePC, CFile::modeRead |CFile::typeBinary);
    int iLen = oldFile.GetLength();
    iLen = iLen / BUFFER_SIZE;
    BSTR bstr = strFileNamePPC.AllocSysString();
    SysFreeString(bstr);
    CeRapiInit();
    HANDLE h = CeCreateFile(bstr, GENERIC_READ | GENERIC_WRITE, 0, NULL,
        OPEN_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);
    char cTemp[BUFFER_SIZE];
    DWORD nbytes;
    int iTotBytes = 0;

        CeWriteFile(h, &cTemp, (DWORD)iReaded, &nbytes, NULL);
    CeCloseHandle(h);
