On the task pane you can use the LinkLabel
control which allows handling clicks on a link and run the system's default web browser programmatically in the following way:
public void InitializeLinkControl()
{
// Create the LinkLabel.
this.linkLabel1 = new System.Windows.Forms.LinkLabel();
// Configure the LinkLabel's location.
// this.linkLabel1.Location = new System.Drawing.Point(34, 56);
// Specify that the size should be automatically determined by the content.
this.linkLabel1.AutoSize = true;
// Add an event handler to do something when the links are clicked.
this.linkLabel1.LinkClicked += new System.Windows.Forms.LinkLabelLinkClickedEventHandler(this.linkLabel1_LinkClicked);
// Set the text for the LinkLabel.
this.linkLabel1.Text = "Visit Microsoft";
}
private void linkLabel1_LinkClicked(object sender, System.Windows.Forms.LinkLabelLinkClickedEventArgs e)
{
// Specify that the link was visited.
this.linkLabel1.LinkVisited = true;
// Navigate to a URL.
System.Diagnostics.Process.Start("http://www.microsoft.com");
}
