I used the code below to display the border for an image in Windows Mobile. But, border is not displaying for all the images, can anyone suggest

C#

hReq = (HttpWebRequest)WebRequest.Create("xxxx.com/" + ImgUrl);
hRes = (HttpWebResponse)(hReq).GetResponse();
Stream str = hRes.GetResponseStream();
picRestLogo.Image = new Bitmap(str);
Graphics g = Graphics.FromImage(picRestLogo.Image);
Pen p = new Pen(Color.FromArgb(146, 146, 146));
Rectangle panelRect = picRestLogo.ClientRectangle;
g.DrawLine(p, panelRect.Left, panelRect.Top, panelRect.Right - 1, panelRect.Top);
g.DrawLine(p, panelRect.Left, panelRect.Top, panelRect.Left, panelRect.Bottom - 1);
g.DrawLine(p, panelRect.Right - 1, panelRect.Top, panelRect.Right - 1, panelRect.Bottom - 1);
g.DrawLine(p, panelRect.Left, panelRect.Bottom - 1, panelRect.Right - 1, panelRect.Bottom - 1);

Thanks in advance,

The code seems correct to me but don't forget to release the resources (use the using keyword or Dispose method). You're maybe facing a memory problem because of that. For example:

//the Graphics object will be disposed automatically with using
using (Graphics g = Graphics.FromImage(picRestLogo.Image))
{
   Pen p = new Pen(Color.FromArgb(146, 146, 146));
   Rectangle panelRect = picRestLogo.ClientRectangle;
   g.DrawLine(p, panelRect.Left, panelRect.Top, panelRect.Right - 1, panelRect.Top);
   g.DrawLine(p, panelRect.Left, panelRect.Top, panelRect.Left, panelRect.Bottom - 1);
   g.DrawLine(p, panelRect.Right - 1, panelRect.Top, panelRect.Right - 1, panelRect.Bottom - 1);
   g.DrawLine(p, panelRect.Left, panelRect.Bottom - 1, panelRect.Right - 1, panelRect.Bottom - 1);
   //release the pen
   p.Dispose();
}
