InvokeRequired not working with my Timer

[Mark Denardo]

Hey all, I'm having a problem with the following:

Private m_myDELEGATE As New myDELEGATE(Addr essOf
ReceivingServer Message_UIThrea d)
Delegate Sub myDELEGATE(ByVa l ReceivingServer Message As NetworkMessage)

Public Sub ReceivingServer Message(ByVal objNetworkMessa ge As NetworkMessage)
If (Me.InvokeRequi red) Then
Dim args() As Object = {objNetworkMess age}
Me.Invoke(m_myD ELEGATE, args)
Else
ReceivingServer Message_UIThrea d(objNetworkMes sage)
End If
End Sub

Basically I use this method to pass control from a worker thread back to the
UI Thread. It works fine if its a normal thread, but when I use a timer and
call this method after the timer elapses, then Me.InvokeRequir ed = False and
it treats it likes its already on the main thread, and thus when I get in
ReceivingServer Message_UIThrea d, I'm getting the all to familiar
"Cross-Thread operation not valid" error.

I thought Timers were just special cases of threads. What is going on
and/or what do I need to do to correct my problem?

Re: InvokeRequired not working with my Timer

Sorry I jumped the gun...my thread is also making Me.InvokeRequir ed return
False. It must be something else I changed. I'll have to investigate more.

Sorry Disregard....fo r now.
