Question
Hi Sir,

I use Turbo C++ v4.5 on Windows Vista. The below-mentioned program always gives an error "Error directive: BGI graphics not supported under Windows.". What can I do to overcome the problem?
This is the source code:

#include <graphics.h>

#include <stdlib.h>

#include <stdio.h>

#include <conio.h>



int main(void)

{

  /* request autodetection */

  int gdriver = DETECT, gmode, errorcode;



  /* initialize graphics mode */

  initgraph(&gdriver, &gmode, "");



  /* read result of initialization */

  errorcode = graphresult();



  if (errorcode != grOk)    /* an error occurred */

  {

     printf("Graphics error: %s\n", grapherrormsg(errorcode));

     printf("Press any key to halt:");



     getch();

     exit(1);          /* return with error code */

  }



  /* draw a line */

  line(0, 0, getmaxx(), getmaxy());



  /* clean up */

  getch();

  closegraph();

  return 0;

}

Thanking you,
Yours' faithfully,
Aashish

Answer
1. Switch to a more current compiler suite and IDE - for example, CodeBlocks+MinGw

2. Use a currently supported gui library - for example, WxWidgets
