    file saving with frog!!!

    well the problem is simple, i don't know how haha
    (i haven't got enough sleep bare with me)

    alright i understand how to open/save/edit text based files
    using C++, I have covered most basic tutorials on C++
    directx, api, mfc, anything i can get my hands on
    including networking(but that still needs work)

    the one thing that i haven't come across is how to access
    data from anouther file within the program?

    i mean data not text based accual data like stored
    variables or something from anouther file??

    if that makes sense sorry if it doesn't

    be a little more specific. what are you trying to do? save your programs state in a file and then load that up and resume you prog. with the data stored in the file? thats a pretty simple task if you alredy know how to read/write to files and if the file is laid in an orderly fassion (i.e. you wrote the file how you wanted it or it follows a strict guidline set down in its formats if so go to http://www.wotsit.org/ and look around at the different formats.

    OK, I'm only thinking that this is your problem: Saving file to specified location:
    Code:
    //Be Sure to include fstream.h!
    
    ofstream save;
    
    save.open("C:\savedfile.txt");
    save<<"Hello";
    save.close();
    Opening a file from a specified location:

    Code:
    //Be Sure to include fstream.h!
    
    ifstream open;
    
    open.open("C:\savedfile.txt");
    if(open.fail())
    {
    cout<<"file opening has failed.";
    }
    open.close();
    I'm only assuming that that was your problem...I hope it helped.

    hmm....

    ok
    i am wondering how i would save cetain information
    into a file *.whatever. things such as variables.
    then i could load these variables back into memory and
    manipulate them.
    i think it would be in binary format like a binary tree or
    something like that. i hope that is a little more clear

    Those two sentences make me think that you dont even know how to read from a file. If you do then this should be a no brainer, you wrote the file so you know how its laid out, just write some code to read in the data and assign it to your variables.

    Important : You have to specify double backslashes in order to generate one backslash.
    The string should be: "C:\\savedfile.txt"
