拷贝许多文件并处理其中数据，显示进度的程序在xp下出现问题，而2000下正确。在xp中选择右键中的兼容性属性页将里面的设为与2000兼容也没有问题。诸位有遇到类似问题的吗？问题具体表现是开始时进度条，进度数据都正确，但过一会儿就进度条显示停止，进度百分数也停止，但调试跟踪这些数据都没有问题。鼠标指针变成沙漏形状。表现象死机了一样，但实际安装进度仍在进行到最后安装处理结果也正常。这是兼容性的问题吧，有哪位大侠遇到过，提提解决意见吧，这两天就要完成呢。处理过程代码是原有代码，仔细看了也没有xp不支持的。

对f1文件中的数据要分段读出处理(处理部分省略了单纯数据运算处理),每次读出一段,计算当前所写的长度,计算进度的当前值和总进度值,f1是许多个分别比较大的文件几兆到十几兆大.所有的显示是由ShowCur函数完成的,这个函数共计调用了23次.CProgressDlg是两个进度条所在窗口类
