Hi, I have tried to do it as you said and i get the following errors :-

My code below :-

-------------------------

Code:

r.c_str(); // convert string r to const char

            p.c_str(); // convert string p to const char

            s.c_str(); // convert string s to const char

            

            const char * rungame = r.c_str();

            const char * directory = p.c_str();

            const char * startf = s.c_str();

    

            



            std::cout << "atoi(r) = " << atoi(r) << endl;

            while(getline(infile,whole)){

                i++;

                std::cout << "i = " << i << endl;

                if(atoi(r)!=i)

                    continue;

                p1=whole.substr(0,whole.find(':'));  

            }  

                  

            outClientFile.seekp(0);    // Go to start of games.db file

            

                        

            std::cout << "Changing directory to  <" << p << ">" << endl; 

            chdir(p); // enter directory of path

            std::cout <<  "Executing system(" << s << ")" << endl; 

            system (s);  // execute start script



            outClientFile.close();  // close file games.db

                        

                        // Here we would check 'choice' and probably move to another functi$

            std::cout<<"\n\n";

            break;

  

            // Here we would check 'choice' and probably move to another functi$

            std::cout<<"\n\n";

            break;



  case '4': //Finished so set finished 'true' to break out of loop

            finished=true;

            std::cout<<"Exiting....\n";

            break;

  default:  //If choice !=1/2/3 then do what it says here

            break;

 

    outClientFile.close();          // close file games.db

 

            //  end functions

  }

  choice='\0'; //NULL

 }

 return 1;



 

}

There seams to be some confusion here.

Code:

r.c_str(); // convert string r to const char

p.c_str(); // convert string p to const char

s.c_str(); // convert string s to const char

The above lines don't change the types of r, p, and s. They simply return a c string version of r, p and s (a c string is a char *).

Anywhere you do something like this:
std::cout << "atoi(r) = " << atoi(r) << endl;

Needs to be changed to this:
std::cout << "atoi(r.c_str()) = " << atoi(r.c_str()) << endl;

            const char * myChar[1024] = p.c_str();

            const char * myChar[1024] = s.c_str();

I don't think this is quite what you want here.... a c_str is a "char *" not a "char **" (or a char *[]).

Code:

const char *temp = str1.c_str();

The above should work just fine. Because c_str() is returning a pointer to a constant char* you shouldn't need to worry about the size of the string... just know you shouldn't be trying to modify it in that form.

Hi,

Thankyou for your reply. I am still having problems converting std::string to const char the errors i
get are below followed with my code.

My code

------------------------------------------------

Code:

r.c_str(); // return a c string version of r

            p.c_str(); // return a c string version of p

            s.c_str(); // return a c string version of s

            while(getline(infile,whole)){

                i++;

                std::cout << "i = " << i << endl;

                if(atoi(r.c_str())!=i)

                    continue;

                p1=whole.substr(0,whole.find(':'));  

            }  

                  

            outClientFile.seekp(0);    // Go to start of games.db file

            

                        

            std::cout << "Changing directory to  <" << p << ">" << endl; 

            chdir(p); // enter directory of path

            std::cout <<  "Executing system(" << s << ")" << endl; 

            system (s);  // execute start script



            outClientFile.close();  // close file games.db

                        

                        // Here we would check 'choice' and probably move to another functi$

            std::cout<<"\n\n";

            break;

  

            // Here we would check 'choice' and probably move to another functi$

            std::cout<<"\n\n";

            break;



  case '4': //Finished so set finished 'true' to break out of loop

            finished=true;

            std::cout<<"Exiting....\n";

            break;

  default:  //If choice !=1/2/3 then do what it says here

            break;

Ok, lets go over this one more time....

If you get an error that says this:
error: cannot convert `std::string' to `const char*' then it means that somewhere in your code (AKA the line in the error message) you are passing in a std::string instead of a c_string (or const char *).

Lets break down the first one.
gamepro11.cpp:160: error: cannot convert `std::string' to `const char*' for
argument `1' to `int chdir(const char*)'

On line 160 we have the following statement:
chdir(p); // enter directory of path
Now, the error says that argument 1 of int chdir(const char*) is the problem. As we see here, p is a std::string. chdir wants a const char *. As a result this needs to be changed to chdir(p.c_str());.

As far as the cross-initialization goes... you don't need the

Code:

const char *rungame = r.c_str();

const char *path = p.c_str();

const char *starfile = s.c_str();

because you aren't using them for anything (at least not in the above code you aren't).

As far as the last type of error goes (error: jump to case label)....
I believe this is the problem:

Code:

            // Here we would check 'choice' and probably move to another functi$

            std::cout<<"\n\n";

            break;

  

            // Here we would check 'choice' and probably move to another functi$

            std::cout<<"\n\n";

            break;

You have two breaks in the same case statement (that code is right before you finish case '3'. Looks like a simple copy paste problem....

Hi,

Thankyou for your reply i fixed the code by doing the following, and it now compiles. Thankyou all for your help :-

Code:

r.c_str(); // return a c string version of r

            p.c_str(); // return a c string version of p

            s.c_str(); // return a c string version of s

            

            {            

            const char *rungame = r.c_str();

            const char *path = p.c_str();

            const char *starfile = s.c_str();

            }

            std::cout << "atoi(r.c_str()) = " << atoi(r.c_str()) << endl;

            while(getline(infile,whole)){

                i++;

                std::cout << "i = " << i << endl;

                if(atoi(r.c_str())!=i)

                    continue;

                p1=whole.substr(0,whole.find(':'));  

            }  

                  

            outClientFile.seekp(0);    // Go to start of games.db file

            

                        

            std::cout << "Changing directory to  <" << p << ">" << endl; 

            chdir(p.c_str()); // enter directory of path

            std::cout <<  "Executing system(" << s << ")" << endl; 

            std::system(s.c_str());



            outClientFile.close();  // close file games.db

                        

                        // Here we would check 'choice' and probably move to another functi$

            std::cout<<"\n\n";

            break;

  

            // Here we would check 'choice' and probably move to another functi$

            std::cout<<"\n\n";

            break;



  case '4': //Finished so set finished 'true' to break out of loop

            finished=true;

            std::cout<<"Exiting....\n";

            break;

  default:  //If choice !=1/2/3 then do what it says here

            break;

Hi, how do i solve my problems, now i have got it to compile please?

1. I have to press enter for program to load
2. Dont ask for game name when adding game to games.db
3. When adding games to the games.db i have to press enter after each line
4. Its storing wrong information into games.db like Please enter full-path to game:;.Please enter name of startup file: e.g ./start$
5. When executing game it does :-

Run Game1. ;.Please enter name of startup file: e.g ./start.sh:Please enter name of game:
Please select game you wish to run:
atoi(r.c_str()) = 0
i = 2
Changing directory to <Please enter full-path to game:>
Executing system(Please enter name of startup file: e.g ./start.sh)
sh: Please: command not found

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

Because you have used:

Code:

using namespace std;

You can get rid of the std::'s everywhere. Doing so will make your code more readable, IMO.

Lines 17-26;
Lines 71, 77, 82, 102, 130, 159:

Because each use of cout here is to print a static string to the screen, the use of string objects is unnecessary. It will cause a (very minor) increase in memory and processor usage, but more importantly in this case, I get the impression that you've confused yourself, and it makes the code more difficult for others to read. Because you don't need to modify what the prompts are saying, I'd suggest that you get rid of the strings and replace the cout lines with (for example):

Code:

cout << "Please enter full-path to game:" << endl;

Line 30:

This is the reason that you have needed to press enter after starting the program.

Lines 73, 79, 104:

Duplicate getlines; these are the reason that you have needed to press enter again after entering something.

Lines 74, 80, 83, 106, 147, 151, 160, 162:

In each of these lines, you've used your prompt string variables, where I think you meant to use line, whole, or some other string.

<edit>
Reading your code again, it looks as though you might be thinking that this:

Code:

std::cout << r << endl;

will take input from the user and put it into r. If this is what you were thinking, remember that cout is an output stream. You need to use cin with the >> operator, or getline()/cin.getline() to get input from the user.
</edit>

Lines 143-145:

These lines are unnecessary, because you don't use the pointers that are returned. If you did need to use something.c_str() a few times, then theoretically you could gain some speed by using pointers like this, rather than calling the function a number of times. You would gain very little speed though, and I'm not sure that the pointer returned by c_str() is guaranteed to be valid after the string changes.

I hope that helps you a bit. :)

Thankyou very much LINUX QUESTIONS and Sind And Everyone Else! My program now works they way it should and works quite well :D .

Anyone want to design a gui for it please?

Thankyou

Hi,

Ok i have ran into to snags in the program what are :-

1. If a user wishes to use parameters on the same line as ./start.sh -whatever -so -so here he/she cannot do that as it tends to have a char limit?

2.After running a program/game the program does not return to the menu like :-

Run Game1. bfsmd
2. Bf1942
Please select game you wish to run:
2
atoi(r.c_str()) = 2
i = 2
i = 3
Changing directory to </home/twirl/bf1942/>
Executing system(./start.sh)
./start.sh: using dynamically linked binary

Please help so i can fix this.

Thankyou

twirl

Sounds like you'd better post the code again. :D Either that or host it somewhere and post a link.

Have a look at GTK or Qt; these are a couple of the more popular GUI libraries available. GTK has a C-style interface, whereas I believe Qt has a C++ interface (classes and so forth). I've dabbled a bit in GTK and haven't used Qt so I can't give you much more info than that.

Once again, I haven't used it but I remember reading that Glade (which uses GTK, IIRC) can be a quick-start for GUIs.

Hi,

Thankyou for your reply, here is my latest code with the problems above. Also how would i add a way so the user can delete what is stored in games.db?

2. Is it possible to add a way of showing the user what servers/games are running?

Thankyou

twirl
