Old programs from VC 6.0 (or later),in C/C++, MFC, can be upgraded to VC++ 2010 (if in Express edition then VC++ 6.0 first via VC++ 2005/2008). C and C++ are not .NET languages, thus there are no problems related to .NET classes for graphics.

You need to write it yourself, something like:


for (int i = 0x80; i !=0; i >>= 1)
{
    if (i & c)
        printf("1");
    else
        printf("0");
}

Hi I try to run my graphic program in the tourbo c++ environment (the system in my computer is windows 7):

C++

#include<graphics.h>
#include<stdio.h>
#include<math.h>
#include<conio.h>
#define pi 3.1415

int main (void)
{
int gdriver=DETECT,gmode,errorcode;
int x,y, pcolor;
double angle,sinofA;
initgraph(&gdriver,&gmode,"..//bgi");
setcolor(6);
line(0,100,200,100);
for(x=0;x<200;x++)
{
angle=((double)x/200)*(2*pi);
sinofA=sin(angle);
y=100+100*sinofA;
putpixel(x,y,9);
}
getch();
closegraph();
return 0;
}

The following Error showed:
this system does not support full screen mode.?

Solution 3

Go for DirectX using VC++ 2010. Thats the best solution for any type of graphics in Visual Studio

This is not necessarily true. Many graphics programs will work perfectly well with GDI+ or even GDI, it depends entirely on the problem to be solved.

Solution 1

If you are using old style graphics where you write direct to video then you should upgrade by looking at the Windows GDI and GDI+ libraries.

GDI is pretty straight forward once you get some experience, +5
