run a C program in visual basic

Posted 13 March 2008 - 02:33 PM

Hi folks,

I want run a c program in visual basic. How can I do this? Actually this program is for wiener filtering. I want to change the parameter of K in visual basic and want to see the different image output. For your information I use mvc++6.

Thanks in advance.

code is given for your understanding.

	float x, xi, H, K, t;
	int i,j, k;

	printf ("Image Restoration System module 5 - Weiner filter\n");

/* Try to open standard image files.  */
	if (argc < 4)
	{

		exit (0);
	}

	im1 = Input_PBM (argv[1]);
	if (im1 == 0)
	{
	  printf ("No such file as '%s'\n", argv[1]);
	  exit(1);
	}

	p = Input_PBM (argv[2]);
	if (p == 0)
	{
	  printf ("No such file as '%s'\n", argv[2]);
	  exit(1);
	}


	if (im1->info->nr != im1->info->nc)
	{
		printf ("Input image is not square. Use ALIGN.\n");
		exit(0);
	}
