Hi all,
I got a form with some dynamically created objects.
When I use FrmGetObjectIndex in TT (and os5 simurator), when there are no
such object ID (the object doesn't exist), it will return frmInvalidObjectId
(equal = -1).
But when I do the same things in Clie N610 (which is os4), it will return
65535.
Finally, if I ran the program in Palm V (os3.2), it will return an fatal
error said the object doesn't exist.
I want to use FrmGetObjectIndex to see if the object exist, is there any way
to do it in all different version of palmos?
You can use the APIs to:
1) Find out how many objects are on the form
2) Iterate through all objects by index
3) Check to see if the object is of a type that would have an ID
4) Convert an index to an ID for appropriate types
Put this all together into a useful utility function.
