.net - When to Set ThreadApartmentState when using Component that is exposed to VB6 -

i have com component fixing @ moment used within vb6 application (and raises events) hosting vb6 program.

this component uses multiple threads perform it's work internally , moves events out layer exposed vb6 application.

in constructor of component called via vb6 application (new myobject) block of code within component gets called

public sub new()   msynccontext = system.threading.synchronizationcontext.current   if msynccontext nothing       using f new windows.forms.form          msynccontext = system.threading.synchronizationcontext.current       end using   end if end sub  

within threads raiseevents received in outer object.

the events find way commscommunicationserror, tricks onto correct thread raising events visualbasic6.

private sub commscommunicationserror(byval theerrornumber integer, byval theorder order)   mrecordingcounter += 1    dim args ordererroreventargs   if theorder.parent isnot nothing       args = new ordererroreventargs(theerrornumber, theorder.parent, mrecordingcounter)   else       args = new ordererroreventargs(theerrornumber, theorder, mrecordingcounter)   end if    posttocommunicationserror(args) end sub  private sub posttocommunicationserror(byval args ordererroreventargs)   msynccontext.post(addressof communicationserrorsend, args) end sub  private sub communicationserrorsend(byval state object)   dim args ordererroreventargs = ctype(state, ordererroreventargs)   oncommunicationserror(args) end sub  private sub oncommunicationserror(byval args ordererroreventargs)   raiseevent communicationserror(args.errornumber, args.order) end sub 

is how should getting done, seeing random crashes in application @ point when 1 of these events raised.

should threads have apartmentstate changed sta(maybe) instead of mta(the default)?

yes, maybe the threads should sta
