copied!<p>MessageBox.Show() method takes the caption, text, icon, buttons and default button of the dialog.However there's nothing mentioned in the .NET Framework documentation that says anything about adding links to a MessageBox </p> <p>However, you can do the effect you want by creating a new class inherited from System.Windows.Forms.Form and add a button (or more if you like), an icon, a label and a LinkButton. Then use the ShowDialog() Method of the Form class to display the message box in modal form. You may also create a class called MyErrorBox (static class in C# 2 or just sealed in C# 1) that contains only one static method called Show() which creates a form, adds the needed controls and displays the form in modal mode. A demonstration of the last method is shown below. Then you can use this class whenever you want and wherever you please!</p> <pre><code>using System; using System.Windows.Forms; using System.Drawing; namespace MessageBoxes{ public sealed class MyErrorBox{ private MyErrorBox(){} private static Form frm; private static string detailsStore; private static TextBox txt; public static DialogResult Show(string caption, string text, string details, Icon icon){ frm = new Form(); frm.Size = new Size(510, 195); frm.Text = caption; frm.ShowInTaskbar = false; frm.ControlBox = false; frm.FormBorderStyle = FormBorderStyle.FixedDialog; PictureBox icon1 = new PictureBox(); icon1.Location = new Point(8,16); icon1.Size = new Size(icon.Width, icon.Height); icon1.Image = icon.ToBitmap(); frm.Controls.Add(icon1); Label lbl = new Label(); lbl.Text = text; lbl.Location = new Point(88,8); lbl.Size = new Size(400,88); frm.Controls.Add(lbl); LinkLabel btn1 = new LinkLabel(); btn1.Text = "View Details"; btn1.Size = new Size(72,23); btn1.Location = new Point(416,96); btn1.Click += new EventHandler(btn1_Click); frm.Controls.Add(btn1); //Ofcourse you can add more buttons than just the ok with more DialogResults Button btn2 = new Button(); btn2.Text = "&Ok"; btn2.Size = new Size(72,23); btn2.Location = new Point(224,130); btn2.Anchor = AnchorStyles.Bottom; frm.Controls.Add(btn2); frm.AcceptButton = btn2; btn2.Click += new EventHandler(btn2_Click); btn2.DialogResult = DialogResult.OK; detailsStore = details; return frm.ShowDialog(); } private static void btn1_Click(object sender, EventArgs e) { frm.Size = new Size(510,320); txt = new TextBox(); txt.Multiline = true; txt.ScrollBars = ScrollBars.Both; txt.Text = detailsStore; txt.Size = new Size(488,128); txt.Location = new Point(8,120); txt.ReadOnly = true; frm.Controls.Add(txt); LinkLabel lnk = (LinkLabel)(sender); lnk.Text = "Hide Details"; lnk.Click -= new EventHandler(btn1_Click); lnk.Click += new EventHandler(btn1_ReClick); } private static void btn2_Click(object sender, EventArgs e) { frm.Close(); } private static void btn1_ReClick(object sender, EventArgs e) { frm.Controls.Remove(txt); frm.Size = new Size(510, 195); LinkLabel lnk = (LinkLabel)(sender); lnk.Text = "View Details"; lnk.Click -= new EventHandler(btn1_ReClick); lnk.Click += new EventHandler(btn1_Click); } } } </code></pre>
