ahh, hmm in the file system_errors its got :_

MAIN MENU
1. AddGame
2. Options
3. RunGame
4. Exit
Please enter your choice:

and that is all

Matir · 09-11-2005, 11:22 PM

And you placed system_errors in the system() call in the code?

twirl · 09-11-2005, 11:28 PM

Hi,

no sorry i dont know how :-( sorry for being a pain

Matir · 09-11-2005, 11:33 PM

Just concatenate " > system_errors" with the s3 before passing it to system().

twirl · 09-12-2005, 12:10 AM

ok, im trying cin.getline(s3,>system_errors, 100); but that seems to be wrong? please excuse my ability to think at 6:10am in the morning.

Matir · 09-12-2005, 12:12 AM

system(s3+" > system_errors");

twirl · 09-12-2005, 12:24 AM

Ok, im getting the following compile errors my code is below also :-

gameserverpro14.cpp: In function `int main()':
gameserverpro14.cpp:82: error: invalid operands of types `char[256]' and `const
char[17]' to binary `operator+'
gameserverpro14.cpp:83: error: syntax error before `,' token

Code:

cout << "Please select game you wish to run: ";
cin.get();
system(s3+" > system_errors");
cin.getline(s3,, 100); //input goes in

Matir · 09-12-2005, 07:40 AM

whoops, my bad. I thought it was a string type. You could do something nasty like:
system ( (string(s3)+" > system_errors").c_str() );

twirl · 09-12-2005, 10:04 AM

ok ty, iv got it as below, because i cant have system above cin.getline as i get compile errors if i do.

Code:

cout << "Please select game you wish to run: ";
             cin.get();
             cin.getline(s3, 100);
             system ( (string(s3)+" > system_errors").c_str() );

twirl · 09-12-2005, 10:11 AM

Hi,

ok iv ran my program where my bf2 gameserver is and this what happened when i try and run it through the program, :-

Run Game1. Battlefield 2
Please select game you wish to run: 1
sh: line 1: 1: command not found

thankyou

Matir · 09-12-2005, 12:24 PM

Yeah, you need to put the command in there, not the number. Get the command from games.db.

twirl · 09-12-2005, 01:25 PM

ok so i need to search my file for entry #, and find the command to run or load it all in memory and use std::map or something.

The problem is i have no idea how todo either of them, as i aint even done anything with std::map yet.

thankyou

I would not use std::map. Instead, just read through the file and count your position.

twirl · 09-12-2005, 03:28 PM

Hi,

i tried changing the code to what is below but that dont seem to fix it, that does, is it because iv got it the wrong way round and it should be i-- and not i++ ?

:-

un Game1. Battlefield 2
Please select game you wish to run:
1
sh: line 1: 1: command not found

My code :-

Code:

case '3': cout<<"Run Game";
             i=0;
             infile.open ("games.db", ios::in);  
             while(getline(infile,whole)){
                 i++;
                 p2=whole.substr(whole.find(':')+1,whole.length());  
                 cout << i << ". " << p2 << endl;
             }                  
             cout << "Please select game you wish to run: " << endl;
             cin.get();
             cin.getline(s3, 100);
             i=0;
             infile.open ("games.db", ios::in);  
             while(getline(infile,whole)){
                 i++;
                 p1=whole.substr(whole.find(':')-1,whole.length());  
                 cout << i << ". " << p1 << endl;
             }              
             system ( (string(s3)+" > system_errors").c_str() );
