Conversion from C#

[Sonhospa]

Dear all :-) I converted a sample from C# to VB and get an error message. It looks simple, but still I don't understand... Would it be possible that C# allows calling an event directly, while VB doesn't? Or did my conversion tool go wrong? Here's the short sample code:

private void OnWaveControlContextMenuPopup(ContextMenu menu)
{
  if (this.WControlContextMenuPopup == null)
    return;
  this.WControlContextMenuPopup(menu);
}

where WControlContextMenuPopup is defined as an event:

public event WControlContextMenuPopupDelegate WaveControlContextMenuPopup;

After conversion I get the error message "Public Event WControlContextMenuPopup in an event and cannot be called directly. Use 'RaiseEvent'...". The error is shown in lines 2 and 5 of the converted code:

Private Sub OnWControlContextMenuPopup(menu As ContextMenu)
	If Me.WControlContextMenuPopup Is Nothing Then             <-----
		Return
	End If
	Me.WControlContextMenuPopup(menu)                          <-----
End Sub

What would I have to change in the VB code to get the required result without error? Thanks for some insight... Mick
