Dear indubidu,
 If you wish to force a picturebox to repaint itself, call Refresh() on it,
like

pictureBox1.Refresh();

 If this does not work, make sure that the pictureBox is visible on the
MainClass form - one quick way to check this is to set the BackColor property
of the pictureBox to Color.Red, so that if it is rendered on the form, you
will be able to see it.

Hi,

Please show me more code, if you want more help with your problem.

I hope your Image must be a bitmap. All graphics in Windows is Bitmaps on
the lowest level.

Here you will find a sample that will show you a GIF image in a picturebox.
Please remember to give the correct path to the image.

package PicBox;

import System.Drawing.*;
import System.Collections.*;
import System.ComponentModel.*;
import System.Windows.Forms.*;
import System.Data.*;

public class Form1 extends System.Windows.Forms.Form
{
private System.Windows.Forms.Button button1;
private System.Windows.Forms.PictureBox pictureBox1;
private System.ComponentModel.Container components = null;

public Form1()
{
 InitializeComponent();
}

/**
 * Clean up any resources being used.
 */
protected void Dispose(boolean disposing)
{
 if (disposing)
 {
  if (components != null)
  {
   components.Dispose();
  }
 }
 super.Dispose(disposing);
}

#region Windows Form Designer generated code
/**
 * Required method for Designer support - do not modify
 * the contents of this method with the code editor.
 */
private void InitializeComponent()
{
 this.button1 = new System.Windows.Forms.Button();
 this.pictureBox1 = new System.Windows.Forms.PictureBox();
 this.SuspendLayout();
 //
 // button1
 //
 this.button1.set_Location(new System.Drawing.Point(112, 168));
 this.button1.set_Name("button1");
 this.button1.set_TabIndex(0);
 this.button1.set_Text("button1");
 this.button1.add_Click( new System.EventHandler(this.button1_Click) );
 //
 // pictureBox1
 //
 this.pictureBox1.set_Location(new System.Drawing.Point(24, 24));
 this.pictureBox1.set_Name("pictureBox1");
 this.pictureBox1.set_Size(new System.Drawing.Size(240, 128));
 this.pictureBox1.set_TabIndex(1);
 this.pictureBox1.set_TabStop(false);
 //
 // Form1
 //
 this.set_AutoScaleBaseSize(new System.Drawing.Size(5, 13));
 this.set_ClientSize(new System.Drawing.Size(292, 266));
 this.get_Controls().Add(this.pictureBox1);
 this.get_Controls().Add(this.button1);
 this.set_Name("Form1");
 this.set_Text("Form1");
 this.ResumeLayout(false);

}
#endregion
