各位大侠帮帮忙！急！！！有高分！

我编写的这个程序是从一个文件中提取有用的数据，然后利用这些数据绘制一幅曲线图。我现在碰到的问题是：这些文件大概都在250KB左右，里面的数据大概有50000个字符左右。我是用INPUT函数将里面字符一个一个的提取分析判断，取出有用的保存到字符串数组中。其中有用到DO WHILE循环。我测试过如果将文件中的字符删除到只剩几十个，我编的程序可以顺利的实现所需的功能。不过执行的速度比较慢。但是如果文件太大，里面的字符太多的话。程序将没有响应。好象死机一样。请问有什么办法解决？

  1.   

    文件中的内容大概如下： " C002000000003-3275905002505100254
                                                                                                D0011BB000380038003180236
                                                                                                        D0011BB000410041003170232
                                                                                                        D0011BB000440044003250240
                                                                                                        D0011BB000470046003290243
                                                                                                        D0011BB000500049003180256
                                                                                                        D0011BB000530052003120259
                                                                                                        D0011BB000560054003140242
                                                                                                        D0011BB000590057003300246
                                                                                                        D0011BB000620060003450246
                                                                                                        D0011BB000650062003440244
    ........后面还有很多。

    doevents吧，我帮你顶。数据库怎么样？
      

  3.   

    :如果是的话，可以改为5万个字符同时读出来处理呀。会快好多倍的。同意， 不过一次读1k， 10k ，100k，，more已经没有很明显差别了读了1k数据以后接着doevent，然后分析，当然可以1k最后的末尾数字是下一个分段
    的开头，需要自己好好组合下了
