Mike,
If your labels are on the form, not in containers you could use the SETALL()
method of the form to call a method in the label. This was VFP 6 days for
me.
If you have containers, this is a good use of BINDEVENTS.
To use BINDEVENTS you need to have 2 methods on the label class.
FormInitEvent
FormInitMethod
Procedure FormInitEvent
THIS.FormInitMethod()
EndProc
Procedure FormInitMethod
** Your code goes here
EndProc
Procedure Init
BINDEVENT(THISFORM, "INIT", THIS, "FORMINITEVENT")
EndProc
If you call the method directly, anticipate strange behavior.
Once in the FormInitMethod procedure you can access objects outside of the
label. Inside the FormInitEvent, it is hit or miss. In my experience, it is
usually a miss in the runtime.
I do not expect any object on the form to exist until the form gets to its
INIT method.
