Thanks a lot. You mentioned that picbox is actually meant to display
images. Now i'm trying to design a software a bit similar to MSPAINT.
What would you suggest for the drawing area??

I tried as you said. It created a bmp file. But when i open it there
was no image. It was just an empty bmp file :( When i tried to open it
with paint it said format not supported :(

this is my code

public void drawwire(Graphics gr)
       {
           Pen p1 = new Pen(System.Drawing.Color.Black, 6);
           Color customColor = Color.Black;
           SolidBrush b1 = new SolidBrush(customColor);
           Point begin = new Point(), end = new Point();
           for (int count1 = 1; count1 <= wire_cont; count1++)
           {
               if (modify.item == 1)
               {
                   p1.Color = Color.Black;
                   b1.Color = Color.Black;

                   if (modify.no == count1)
                   {
                       p1.Color = Color.Red;
                       b1.Color = Color.Red;
                   }
               }
               if (wire[count1] != null)
               {
                   begin = wire[count1].getBeginning();
                   end = wire[count1].getEnding();
                   gr.FillRectangle(b1, begin.X - 4, begin.Y - 4, 8,
8);
                   gr.FillRectangle(b1, end.X - 4, end.Y - 4, 8, 8);
                   gr.DrawLine(p1, begin, end);
               }
           }
       }

private void toolStripButton2_Click(object sender, EventArgs e)
       {
           Bitmap print = new Bitmap(100, 100);
           using (Graphics pri = Graphics.FromImage(print))
           {
               drawwire(pri);
           }
           print.Save("E:\\print.bmp");
       }
