Hi,
I just has a simple test on it.

VFP COM EXE

DEFINE CLASS myclass AS SESSION OLEPUBLIC

    PROCEDURE longProc
        FOR I =1 to 100000
        NEXT
    ENDPROC

ENDDEFINE

VB APPLICATION

PRIVATE SUB Command1_click

DIM myobj as mydll.myclass

SET myobj = NEW mydll.myclass

myobj.longproc             ' VB APP PENDING HERE UNTIL THE FOR LOOP FINISHED

SET myobj = NOTHING

END SUB

Since EXE also wait for process to be finished, should I built my module as DLL if it is just a desktop application?

Thank you
