<yourPictureBoxName>.Image = System.Drawing.Image.FromFile("path to file");

and i think you don't even need to use the refresh method.

Your complete program

using System;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication5
{
  public partial class Form1 : Form
  {
    private Image MainImage;
    public Form1()
    {
      InitializeComponent();
    }
    private void button1_Click(object sender, EventArgs e)
    {
      using (OpenFileDialog openFileDialog = new OpenFileDialog())
      {
        if (openFileDialog.ShowDialog() == DialogResult.OK)
        {
          MainImage = Image.FromFile(openFileDialog.FileName);
        }
      }
    }

    private void button2_Click(object sender, EventArgs e)
    {
      pictureBox1.Image = MainImage;
    }

Hello,

Just set again the property for the image, PictureBox.Image = ... or any other code you call to load the image in the first place.

Application.DoEvents 'be aware you get many messages not to use it.

If you then get code returned, watch that code if it is maintainable and works.

Where are you setting the image for the picture box initially?

Just set the same property of the picturebox on button click and it will work.

Hello again ram,

A couple of questions, are you developing a web or desktop application?

Are you setting the original image for the picture box in the designer?

What property are you using to set the image? Image?, ImageKey?

Did you read my post?

This is what I've suggested in the beginning to just set the image for the picture box again.

You could also try the method Update() after your refresh. This has the effect that it redraws the control and all its child controls. e.g.

PictureBox1.image = yourimageBitmap;
PictureBox1.Refresh();
PictureBox1.Update();

Hope this helps and Keep programming!
