I have never seen that error before. Here is the OnClick method from a test program I just created:

private void button1_Click(object sender, System.EventArgs e)
{
    System.Diagnostics.Process.Start(
         "http://www.haldeemar.com/hal");
}

Please post you code.

Hal

Hello Hal:
I attach my code.

private void Button1_Click(object sender, System.EventArgs e)
{
if(ListBox1.Items.Count != 0)
{
if(ListBox1.SelectedItem != null)
{
string leyenda = "";
this.HyperLink1.Text = ListBox1.SelectedItem.Text;
this.HyperLink1.NavigateUrl = ListBox1.SelectedItem.Text;
leyenda = ListBox1.SelectedItem.Text;
System.Diagnostics.Process.Start("leyenda");
}
}
}

leyenda contnts is = "C:\Documents and Settings\Adolfo\Mis documentos\269.JPG"

Really I want to open a .JPG document

Regards.

System.Diagnostics.Process.Start is looking for an object named leyenda (since you have it in double quotes).

If leyenda is a variable it should be

System.Diagnostics.Process.Start(leyenda);

I put as you said but continue with same error.

Just a guy wrote me and his suggestion work OK:

Response.Redirect(leyenda);

Thanks you Hal, very much
