Hi,

I am using this function to unbind the client.
But i am getting Error -"Object Reference not set to an instance "
on the line - ubtrp = objclient.UnBind()

Private Shared Sub UnBind(ByVal objclient As SmppClient)
Dim ubtrp As pduUnBindResp
ubtrp = objclient.UnBind()
Select Case ubtrp.Status ...
