Afr0	Trying to save a string to a file in C++ through UDK... // SaveLib.cpp : Defines the exported functions for the DLL application. // #include "stdafx.h" #include <fstream> #include <iostream> using namespace std; extern "C" { __declspec(dllexport) unsigned int SaveGame(wchar_t* LevelName, wchar_t* SavePath) { static ofstream SaveStream(SavePath, ios::out); SaveStream << LevelName; SaveStream.close(); MessageBox(0, LevelName, SavePath, MB_OKCANCEL); return 1; } } --v This code produces the string '10396BE0' in the save file from the string 'TestLevel'. Doing SaveStream << LevelName; --v produces the string '84'. Is this the address of the pointer?! I thought derefencing the pointer would retrieve the value stored at the address?? Edit: Yes, the parameters have to be wchar_ts, because that's what UDK accepts as strings... -=-=- Afr0 Games Project Dollhouse on Github - Please fork!

Sticky	I wrote some binary input\output stuff in C++ the other day. This may help, but I'm not too sure about using C or UDK. // Reading in stuff uint8_t mNumRows; // elsewhere fFile.read((char)&mNumRows, sizeof(mNumRows)); --v // Writing out stuff uint8_t length; // elsewhere fFile.write((char)&length, sizeof(length)); --v Of course, in the actual code I'm reading and writing structs with two uint32_t's, a std::string and a uint8_t. This is also all using this code below, which isn't quite the way you're doing it. fstream fFile; fFile.open(sFilename.c_str(), std::ios::in \| std::ios::out \| std::ios::binary); --v -=-=- last.fm

Afr0	What's fFile? Is it an ofstream instance?

Sticky	Haha, just updated my post as you made your own. // class header private: std::string sFilename; std::fstream fFile; --v -=-=- last.fm

Afr0	I found the solution! I needed to declare a wofstream instead of an ofstream. -=-=- Afr0 Games Project Dollhouse on Github - Please fork!
