楼主好人啊，厉害！
在VC里编译出现一个错误：Error spawning cl.exe
这是怎么回事？

好像是VC的设置问题。百度知道里看看：
http://zhidao.baidu.com/question/20787147.html
还有，据说就现在看来，VC6.0有些问题。我用的是VS2008.还比较好用。

在devcpp和vs2008里都试过，可以用。不过那个数据的格式比较复杂。。其实是用512*2个字节，像素是128*50。 ...

for(iVert=0;iVert<NHEIGHT;iVert++){
                     SetRect(&rectPerDot,0,0,cxPerRect-1,cxPerRect-1);
                     OffsetRect(&rectPerDot,0,iVert*cxPerRect);
                     for(i=0;i<NWIDTH;i++){
                              OffsetRect(&rectPerDot,cxPerRect,0);
                              byteColor=  ((arrMovie[curField][iVert][i/8]) & (1<<i%8)) ? 0:255;
                              hBrush=CreateSolidBrush(RGB(byteColor,byteColor,byteColor));
                              FillRect(hdc,&rectPerDot,hBrush);//do NOT need to select the brush to hdc
                              DeleteObject(hBrush);
                              if(i%8==0){
                                    MoveToEx(hdc,(1+i)*cxPerRect,0,NULL);
                                    LineTo(hdc,(1+i)*cxPerRect,cxPerRect*NHEIGHT);
                              }
                     }
            }
}
这个是画图的。
