    Need help on code to execute the program

    i need some help, iam a newbie who just start to learn c++.

    I want to write a program in c++ that would execute program files. Any files, like .doc, .jpg, or any others.

    I also want to set a timmer on when to execute each program.

    can some one help me out and show me some pointer on where to look

    Thank you very much,
    Have a happy Holiday.

    If by execute, you mean open... cause you can't execute a .doc, but you can execute the program to view a .doc

    Your best bet would be the system(file or directory) function which will open anything in the parameter with its default editor. Don't get used to this command too much, you could end up writing a security nightmare if it's used improperly.

    As for making a timer, you could look into the Sleep(seconds) function... which will halt a program and return as soon as the time elapsed.

    There are better ways of doing this program, but this is the most Quick and Dirty method. It's also the easiest to understand for a beginner.

    shellexecute is't too hard to understand,

    Code:
    #include <windows.h>  //You need shell32.lib for this one 
    
    int main(void)
    {
      char szPath[] = "C:\\WINDOWS\\desktop\\yourapp.doc"; put your filepath here
    
      HINSTANCE hRet = ShellExecute(
            HWND_DESKTOP, //Parent window 
            "open",       //Operation to perform  
            szPath,       //Path to program
            NULL,         //Parameters
            NULL,         //Default directory
            SW_SHOW);     //How to open ' this param here can be minimised, normal, maximised etc..
    
      /*
      The function returns a HINSTANCE (not really useful in this case)
      So therefore, to test its result, we cast it to a LONG.
      Any value over 32 represents success!
      */
    
      if((LONG)hRet <= 32)
      {
        MessageBox(HWND_DESKTOP,"Unable to start program","",MB_OK);
        return 1;
      }
    
      return 0;
    }

    Why'd you change the path in the string variable?

    Ah... no he's not looking for File I/O. He's looking to run a program in his program at a set time.
