hey all,

could someone please help me translate the following c# snippet:

public event EventHandler BubbleClick;
protected void OnBubbleClick(EventArgs e)
{
if(BubbleClick != null)
{
BubbleClick(this, e);
}
}
i'm particularly having problems with the if statement.

thanks,
rodchar

(via Instant VB):
Public Event BubbleClick As EventHandler
Protected Sub OnBubbleClick(ByVal e As EventArgs)
    If BubbleClickEvent IsNot Nothing Then
        RaiseEvent BubbleClick(Me, e)
    End If
End Sub

However, you do not really need the check against the hidden (nearly
undocumented) VB EventNameEvent variable if all you're doing is calling
RaiseEvent. RaiseEvent will gracefully handle cases where there are no
subscribers to the event.

C# doesn't call the event handler unless it is assigned.

So I think it should read in VB

protected sub OnBubbleClick(byval e as eventargs)
raiseevent bubbleclick(this, e)
end sub

Try out this site. It works great for going back and forth between C# and
VB.NET
