>>>Hi,
>>>
>>>I dropped an object (class) on a form. Then in the form LOAD method I check if this object is NULL as following:
>>>
>>>isnull( thisform.MyObject )     && Returns .F.
>>>type( "thisform.MyObject" )   &&  Returns "O"
>>>
>>>
>>>So I presumed that the object is instantiated in the LOAD method of the form. But when I call a method of this object in LOAD method of the form, I get error that the object does not exist. Does it mean that the object is fully instantiated only in the INIT method of the form?

>>Yes

>>But you can add the object in the load() of the form prior to using it

yes - or -
this.NewObject('MyObject', "MyObjectClass", "ClassLib")
