请分析一下为什么读文件出错

[wwangzhihang100]

blResult = mFile.Open("c:\\debug\\result.txt", CFile::readOnly|CFile::typeText);
while (mFile.ReadString(myBuffer, 1000))
{
iMvdxStart = mBuffer.Find("mvdx:") + 4;
mBuffer = mBuffer.Right(mBuffer.GetLength()-iMvdxStart);
sBuffer = mBuffer.GetBufferSetLength(mBuffer.GetLength());
p = strtok(sBuffer, ",");
mTemp = p;
}

哪里发生错误了呢？

[wzh0714]

提示什么错误？这样看这是没有错。

[idAnts]

这段代码不能执行，如文件的时候提示操作文件错误。

blResult = mFile.Open("c:\\debug\\result.txt", CFile::readOnly|CFile::typeText);
while (!mFile.EOF) // 判断文件是否结束
{
if(mFile.ReadString(myBuffer, 1000))

iMvdxStart = mBuffer.Find("mvdx:") + 4;
mBuffer = mBuffer.Right(mBuffer.GetLength()-iMvdxStart);
sBuffer = mBuffer.GetBufferSetLength(mBuffer.GetLength());
p = strtok(sBuffer, ",");
mTemp = p;

[wwangzhihang100]

还是不行。运行的时候提示我对result.txt文件操作的时候发生了一个不明的错误

[布学无数]

你确定每次读到的内容都包含"mvdx:"吗？
如果有不包含的情况，那么可能就出错了~```

[wwangzhihang100]

mFile.ReadString(myBuffer, 1000)第一次read就出错了
