C++ fstream: More signs readen than intended

this issue is really strange to me.. I'm creating and writing into a simple file. When I'm reading with this code:

return_chars = new char[10];

file.read(return_chars, 10);

The result simply contains 4 characters more! It's 14 signs long. This happens only when reading 10 characters and some certain other numbers (24 for example). At a length of 8 it doesn't happen. The signs it adds are always the same at 10 characters: CE=0

This is the code I use for example to show what I read from the file:

MessageBoxA(NULL, return_chars, "title", 0);

Where is the issue? o.o Lots of thanks in advance!

Just a guess from the limited information you gave, maybe the showText method doesn't handle the return_chars array correctly because it isn't a null terminated string? You could try,

return_chars = new char[11];

file.read(return_chars, 10);
return_chars[10] = '\0';

showText(return_chars);
