//
void dir(string strFile)
{
    WIN32_FIND_DATAA    find;
    HANDLE    hFile;

    //out_str(strFile);
    int    nCount = 0;
    
    if((hFile=FindFirstFile(strFile,&find)) != INVALID_HANDLE_VALUE)
    {
        out_str(find.cFileName);
        nCount++;
        while(FindNextFile(hFile,&find))
        {
            out_str(find.cFileName);
            nCount++;
        }
        printf("%d files found\n",nCount);
        FindClose(hFile);        // must close  the handle
