Dislin Visual Studio : Graphics not displayed

[Puneet Ginoria]

Hi , I have made a C program in C and i try to run it through visual
studio 2010 . It runs but shows no output. What is the problem ?

Here is the code:

#include "stdio.h"
#include "stdafx.h"
#include "stdlib.h"
#include "dislin.h"
#include <math.h>
#include <Windows.h>

int main()
{

int w = 800;
int h = 600;
int n = w*h;
unsigned char *d = (unsigned char *)malloc(n*4); // reserve place for

metafl("VIRT");
window(0,0,w,h);
winsiz(w,h);
page (w, h);
disini();
rectan(0,0,w,h);
imgmod("RGB");
imgini();
rpixls(d,0,0,w,h);
imgfin();
disfin();
getchar();
return 0;
}

Hi Puneet,

you are using the output device "VIRT" in metafl. This keyword means
that
the graphics is just created and hold in memory. If you replace "VIRT"
by
the keyword "CONS", your plot will be displayed on the screen.

Best regards,

Helmut
