See more:

After executing program it gets directly out side of project. I don't know why it happens.

C#

for (int i = 1; i != POINTS_ON_CURVE-1; i += 2)
{
  g.DrawRectangle(newpx, new Rectangle((int)p[i + 1], (int)p[i], 1, 1));
  g.Flush();
  Application.DoEvents();
}

After executing it gets off.

Plz help me.

Added from comment below:

ptList.Add(162); 
ptList.Add(127); 
ptList.Add(204); 
ptList.Add(124); 
ptList.Add(304); 
ptList.Add(207); // how many points do you need on the curve? 
const int POINTS_ON_CURVE = 1000; 
double[] ptind = new double[ptList.Count]; 
double[] p = new double[POINTS_ON_CURVE]; 
ptList.CopyTo(ptind, 0); 
bc.Bezier2D(ptind, (POINTS_ON_CURVE) / 2, p); 
//pictureBox1.Refresh(); 
// draw points 
for (int i = 1; i != POINTS_ON_CURVE - 1; i += 2) 
{ 
  g.DrawRectangle(newpx, new Rectangle((int)p[i + 1], (int)p[i], 1, 1)); 
  g.Flush(); 
  Application.DoEvents(); 
}

it is a program for drawing a curve when i go to execute it executes correctly but after drawing a curve it directly close the window

Not enough information. For a developer, there is not such things as "get out", etc.
Can you simply use the Debugger and explain what happens?
Bad question.

Solution 1

You Application.DoEvents already tells me you're doing something wrong. Is it inside OnPaint or handler of the Point event? Where did you get g? It looks like you have no idea on how to render graphics correctly and change it.

First of all, use Debugger to see what's going on.

See also my comment. I cannot help you if your explanation of the problem is so sloppy. You also don't show enough code.

ptList.Add(162);
ptList.Add(127);

ptList.Add(204);
ptList.Add(124);

ptList.Add(304);
ptList.Add(207);

// how many points do you need on the curve?
const int POINTS_ON_CURVE = 1000;

double[] ptind = new double[ptList.Count];
double[] p = new double[POINTS_ON_CURVE];
ptList.CopyTo(ptind, 0);

bc.Bezier2D(ptind, (POINTS_ON_CURVE) / 2, p);

//pictureBox1.Refresh();
// draw points
for (int i = 1; i != POINTS_ON_CURVE - 1; i += 2)
{
g.DrawRectangle(newpx, new Rectangle((int)p[i + 1], (int)p[i], 1, 1));
g.Flush();
Application.DoEvents();
}
}

I copied this comment to your original question and formatted it. You'll want to make sure I didn't mess anything up in copying.

OK, this is all wrong. Where is your Paint or OnPaint? You don't show right part. You need to separate rendering and data. Basically, rendering should be under Paint, only DrawXXX operations. If you need to change it, you need Invalidate (nothing else). If you change it on a regular basis (like in animation), you need a thread for this.
