    Try reading the FAQ
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    Use system(). If I wanted to use the command "cd C:\WINDOWS" I would use system() like-
    Code:
    system("cd C:\WINDOWS\")
    and it would change the current directory to C:\WINDOWS\.

    More than how to follow a link?

    >>system("cd C:\WINDOWS\")
    Not very useful, in practical terms. It doesn't change the current working directory.
    When all else fails, read the instructions.

    cant back to c:\

    i have made a program as below:

    Code:
     /* 
    #include <stdlib.h>
    
    int main(void)
    { 
        system("cmd.exe");	
        return 0;
    }
    
    */
    the output is a comand prompt but not cmd.exe, but with the tilte testing.exe(testing, which is my project name), and i cant use system() to go back to c:/

    what should i do?

    Explain what you are trying to do, think it through thuroughly, and try again

    ok...what i am trying to do is......

    at the beginning , i wanna start a acrobat distiller with c++, but is seems too difficult for me, then i found that i can use dos command to start the distiller in the dos prompt.

    what i am trying to do is to write a program, which is used to start the distiller, and so serveral operations automatically once the program being ran.

    and first i would like to try out out to use C++ to control the dos prompt. but fail.

    for example, how to generate a dos prompt(cmd.exe) from a program?
    i cant do so in the program i have post before, is ti because i have use the win32 console application?
