I have a code exception. I try to ping some host and an exception occur. I know that the host does't exist and I wanna tell the user that the host doesn't exist. So how to handle the exception?
start.aspx
<form runat="server">
<asp:TextBox ID="HostName" runat="server"></asp:TextBox>
<asp:Button ID="CheckHostBtn" runat="server" Text="Check" />
<asp:label ID="HostStatus" runat="server"></asp:label>
</form>
start.aspx.vb
Partial Class RootStart
Inherits System.Web.UI.Page
Private Sub CheckHost() Handles CheckHostBtn.Click
HostStatus.Text = General.PingTest(HostName.Text)
End Sub
End Class
General.vb
