I've looked through the help files and several pages of these forums, but I can't find anything that works for me.

I need to save various pieces of data, mostly arrays to a file. I tried the basic commands included with DarkGDK, but they did not work for some reason. I also tried both ways shown here, but they didn't work either.

I'm at a total loss. Thanks in advance for any help.

I believe you should have a header file called fsstream. (If not you can probably get it somewhere).

That might solve your problems.

basically yes. I need to be able to write a save file including multiple variables, and then read it on a future play-through. Preferably, the data stored would not be readable in a text editor.

Also, I've played around with different include files to see what works and what doesn't, and several of the basic C++ header files stop the game from compiling successfully when included. For example, the include needed for strings. Am I doing something wrong with these that could be the source of my problem?
includes that stop the game from compiling:
#include <istream>
#include <iostream>
#include <string>

I don't seem to have that file. what does it do anyhow?

fstream.h is for reading and writing into files and it's realy easy to use. But I can't load this header file when I include the DarkGDK.h file

If someone knows how to use C++ Libraries and DarkGDK.h at the same time pls tell me

Assuming you're compiling in debug mode, try switching to release mode and see it the compile will go through.

It's a common problem when you include portions of the std library. Dark GDK doesn't have a debug version so it can't find the link.

Well, now my code compiles, but it returns a memory access violation whenever I try to read data from a file. writing works fine, but reading crashes the program. Thoughts?

If it makes a difference, the file is not read only, and I have full admin rights. (running vista)

yea the only c++ libs you can use really is
stdio (which is pre-included by default)
dark gdk refers to other libraries causing conflicts when including them.
sudjestions:
make a dll (i don't know much bout them) but i think you can treat them almost like header files. you can have it run independent of dark, you use a function called dbCallDLL (or something like that i don't remember, its in the manual)

header files i believe will conflict due to inheritance of libs (haven't tinkered with it too much so not 100% certain there is a way around it)

you can make a class object.
these don't inherit, they are almost like seperate programs called by your program. (helps if you know a bit about object oriented programming)



if you are getting a memory access violation, well did the compiler say like continue debug or break
if so hit continue

another idea would be to go to your debug or release folder and transfer the .exe to your project folder (ProjectName\projectname)
i think the directory access on dark causes conflicts with vista's defense mechanisms.

i would get an error whenever compiling because i would access a .pk3 file that was in my project directory but my exe was not running in the project directory (it was in the debug)
vista thinks that someone is trying to change data against your will and will crash your program.

i hope some of that helped
