Problem with reading large text files
Author
Hi, i have written a wrapper class for text files. It works fine for many text files i have tested for now.
But just for example, i used it to read "DDraw.h" and copy it to a new file. DDraw.h is approximately 137 KB in size, and i have compared the size of bytes in the Explorer with that returned by GetSize(), they were equal.
But reading this file and copying the content to a new file, the last 50-60 lines are not in the destination file! The memory buffer is allocated without any error.
Look at this source code, please!
Can someone give me a hint what could be wrong here?
thanks

Either the GetSize() function does not return the correct value or the code for "copying the content to a new file" is broken.
Since it is a text file, the problem might be caused by "\r\n" vs. "\n".
