Hey all ... this has got me stumped. At some point I cut off a part of a string by placing a "\0" in it. The problem is though, that at a later point I need to add another string to this string, which isnt possible, as it will be added AFTER the "\0", so effectively the string doesnt change... How can I do this so that I DO get the new part attached to it?

Assuming these are std::strings, use erase to cut the string instead.

mystring.erase(pos);

Instead of

mystring[pos] = ''\0'';

Then you can append a new string without a problem. The problem here is that a std::string is not a 0-delimited string by nature - you inserting ''\0'' in it doesn''t really change the string (it still has the same length).

Copy the string starting at the position of ''\0'', then add one at the end of that string.
