Using OCX in a Windows Service

[Mahesh]

Hello there,

I am creating a windows service to monitor wireless terminals and then
transmit the barcodes to the clients. The service needs to use a OCX (I hate
to use OCX in a service but, without OCX, you wont be connected to the base
station). I have added a form and used the ocx on the form only to connect to
the base station.

However, I do get a message in the event log. The service won't start.

Service cannot be started. System.Threading.ThreadStateException: ActiveX
control '244758c6-a002-11d2-b82b-938daecfce37' cannot be instantiated because
the current thread is not in a single-threaded apartment.

I have set [STAThread] attribute and also tried

System.Threading.Thread.CurrentThread.TrySetApartmentState(System.Threading.ApartmentState.STA);

Could you please let me know what I am doing silly here?

Did you ever find a solution to this? We are trying to implement the same thing (using a datalogic OCX COM object) to read barcodes as a server service and dump them into a .txt file.
