How can I open another .exe file in my DOS-program.
How can I open another .exe file in my DOS-program.
do you mean execute another exe or open it and view the content?
system("MyProgram.exe"); will execute it, also look into the various spawn and exec functions
otherwise:
This code reads the contents of a file
there are numerous other ways to read from a file but this is just one.Code:FILE *fptr; //file pointer fptr=fopen("MyFile.txt", "rb"); //open file as read binary mode while(YourMomIsFat) //usually check for eof or something { variable=fgetc(fptr); //read a byte UseVariableInSomeWay(); }
in c++
Code:#include <iostream> #include <fstream> ... ofstream fout=("c:\\whatever\\new.txt"); if (!fout.is_open()) { cerr<<"Oops, file can't be created or opened."<<endl; exit(1); } fout<<"Some Text"<<endl; fout.close(); ifstream fin=("c:\\whatever\\new.txt"); if (!fin.is_open()) { cerr<<"Oops, file can't be opened."<<endl; } fin>>someText; cout<<someText; fin.close(); ...

One line of code, the obvious best choiceCode:Open file.txt and read it.
There are standard functions in C. All compilers are supposed to have them. Same deal with C++.
well duh!!! But thats not why hes asking, you cant expect someone to know all the standard c/c++ functions and understand exactly how to use them.
Thanks people....
I use Borland 5.02

There are several functions that allow you to excecute a file and are better to use than system("whatever.exe").
Do I hear an echo in here? Also, dont trust that include file, I dont think its dos standard.
True, but I'd say that most people who have been programming for a while know a pretty good deal of them (if not all of them) and how to use those that they know of. The c standard library isn't a very big library.Originally posted by thedumbmutt

But he did ask, so that would suggest he needed some sort of help, examples are nice sometimes.
You're good at picking nicknames, I'll give you that.
