arguments, directories and stuff...

i have this program... like any program and i would like to make it so that when u type /h after it would go completely silent like that it would print anything on the screen(already covered the code where it doesnt print anything) but i was wondering moe about the commandline arguments and stuff...


and case two... if my program creates a file... how can i change the directory where it puts them ?

>> i was wondering moe about the commandline arguments and stuff

Code:

---

int main(int argc, char *argv[])
{
    if(argc != 0)
    {
        for(int i = argc; i > 0; i--)
        {
            if(strcmp(argv[ i ], "/h")
            {
                // Put ur dont print anything function here
            }
        }
    }
}

i THINK thats how you do it, im not 100% sure, oh and strcmp() needs the string.h file.

Before you create the file, use this function:

Code:

---

The SetCurrentDirectory function changes the current directory for the current process.

BOOL SetCurrentDirectory(

    LPCTSTR lpPathName        // address of name of new current directory
  );

---

Parameters

lpPathName

Points to a null-terminated string that specifies the path to the new current directory. This parameter may be a relative path or a fully qualified path. In either case, the fully qualified path of the specified directory is calculated and stored as the current directory.

Return Values

If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

Each process has a single current directory made up of two parts:

· A disk designator that is either a drive letter followed by a colon, or a server name and share name (\\servername\
sharename)
· A directory on the disk designator

Or, you could use the system() function with CD, ie:

system("CD path");

SetCurrentDirectory() needs windows.h and system() needs stdlib.h

> if(argc != 0)

Why do you have this check?
argc will never be zero. It will always be at least 1. The first argument is the name of the executable itself.

Quzah.

you can specifify fully qualified names, like this:
>fopen("c:\\mydir1\\mydir2\\myfile1", "w");
or
>fopen("/home/usr/bob/bobsfile", "w");

and relative like
"subdir/myfile.txt"

Remember to double up the backslashes if you are using them for DOS files.
