I disappointed. I'll try do something with timer. Do you know will VFP9 support real multithreading.

I try this sample which you did. I understand mean that do what I needed (Client application don't wait for process). But that give an error at
"loContext.SetComplete()" line. about that not an object.


rr=CREATEOBJECT("math")
rr.multiple(2,4)

DEFINE CLASS Math AS SESSION OLEPUBLIC
FUNCTION Multiple(tnNum1, tnNum2)
LOCAL lnResult, loMtx, loContext

* Create a reference to the MTS object
loMtx = CREATEOBJECT("MTXAS.APPSERVER.1")

* Create a reference to the Context object
loContext = loMtx.GetObjectContext()

lnResult = tnNum1 * tnNum2

* Commit the transaction if there is one and
* tell MTS that we're done using the component
loContext.SetComplete()

RETURN lnResult
ENDFUNC
ENDDEFINE
