The BINDEVENT() function should only be used to bind to the native VFP objects. See help for details.
For COM objects there's EVENTHANDLER() Function.

>I have a simple form with a mscomm control and a container object.
>In Init of the contailner I have
>BINDEVENT('mscommname', 'oncomm', this, 'moncomm', 1)
>Where 'moncomm' is a custom method.

>o = NEWOBJECT('form1', 'classname.vcx') Fox crashes.
