readfile()
If the return value is nonzero and the number of bytes read is zero, the file pointer was beyond the current end of the file at the time of the read operation.
When a read operation reaches the end of a file, ReadFile returns TRUE and sets *lpNumberOfBytesRead to zero. Windows CE does not support asynchronous read operations on files.
各位,madn确实也给出了错误原因,可是我不知道该如何下手解决此问题??多谢了
