The Command Prompt

[kcddoorman]

I did a little fun program in C++ for the guys at work that picks random numbers for their Nascar pool. The random numbers are printed each on a new line and it always goes over the default viewing area which is annoying to me.

Is there something like the SetWindowPos function for the command prompt?

If I could give it some coordinates to follow when executed or even have the window go full screen.

Thanks-a-bunch,
James

Just to clarify - you are trying to resize the console window that the random numbers are output to?

What is your OS?

Hazerding a guess, I'd say it is Windoze given the reference to SetWindowPos().

At the command line, type start /?. I think that is what you are looking for.

This is just a plain C++ command prompt program. Nothing special. I was just asking about the SetWindowPos because its the closest thing I could find to solve the problem. SetWindowPos works for windows applications only I think.

Found this in an old C for Dummies book from a long time ago. Works well enough but I question the randomness of the random numbers.

Here's the code.

#include <stdio.h>
#include <stdlib.h>
#include <time.h>    
 
#define DRIVERS 43    
#define PICKS 43        
#define DELAY 1000000    
 
 
int rnd(int range);
void seedrnd(void);
 
void main()
{
    int numbers[DRIVERS];    
    int i,b;
    unsigned long d;    
 
    printf("  N A S C A R  P O O L \nSRANDOM NUMBER GENERATOR\n\n");
    seedrnd();        
 
/* initialize the array */
 
    for(i=0;i<DRIVERS;i++)    
        numbers[i]=0;
 
    printf("Press Enter to pick this week's numbers:");
    getchar();
 
/* draw the numbers */
    printf("\nHere they come: \n\n\n");
    for(i=0;i<PICKS;i++)
    {
        for(d=0;d<=DELAY;d++);    
 
/* picks a random number and check to
see if it's already been picked */
 
        do
        {
            b=rnd(DRIVERS);    
        }
        while(numbers[b]);    
 
        numbers[b]=1;        
        printf("%i \n",b+1);    
    }
    printf("\n\nGood luck in the drawing!\n");
    printf("\n\nPress the enter key to exit.\n");
    getchar();
 
}
 
/* Generate a random value */
 
int rnd(int range)
{
    int r;
 
    r=rand()%range;        //spit up random num.
    return(r);
}
 
/* Seed the randomizer */
 
void seedrnd(void)
{
    srand((unsigned)time(NULL));
}

By C++ do you mean C? I've written a very similar program in C.

Is there another question here? I've looked at the start command and discovered that it only allows you to maximise the window. If you want something else, you will have to execute a .lnk file which has the appropriate properties set.
To create and set one up:

1. right click and drag your executable, then release.
2. Then rename it to what you want.
3. Right click on it and set the properties to that which you want.
4. from your app, execute the file name though the cmd programme. Don't forget to append .lnk extention to it. I.e.

   system("cmd /c myexe.lnk");

Hope this helps.

If I got you correctly, the console window isn't large enough to hold all the numbers? In that case, there is a way to change that and keep it simple.

When the console pops up, click the upper left corner and go to Properties.

Click the Layout tab

At the "screen buffer size" field, type in however many lines you want in the Height field.

Click OK and Save properties.

It gets the work done without any unnecessary coding.

I got it to work using the properties dialog for the executable. I would have thought their would be some piece of C code that would do it though.

Thank You for all your ideas.
