cannot get a ref parameter on a thread

Guest

Greetings,

I have a COM reference that connects to a device to get some data... if I
don't use threads to get data i can get the "ref int events" without any
problems but if it's running inside a thread it doesn't touch on the
variable value

How can I workaround this?

Diogo,

What is the apartment of the COM object? More likely than not, it is an
STA threaded object, and you need to set the ApartmentState property of the
thread to ApartmentState.STA ^before^ you make any calls to COM objects.
