Hi,

I have encountered an extremely frustrating problem that should have been a
cinch to fix but I just can't get it solved.

If I have a custom datafile property defined for a datafile object, using
the grabber, how the heck do I acces this property's value inside my
program????

I've tried the get_datafile_property function but I just do not understand
the docs for it, and I've tried every combination of stuff for the "type"
parameter, but it just keeps returing empy strings - it NEVER returns a
value no matter what type id I give it!

I have a property called "XDIM" defind for the particular object I want it
associated with. I can access this property just fine in the grabber, but
when I get into my program HOW do i get this value back? XDIM is set to 98,
HOW do I access this value in the program?!

This problem is driving me wild 'cause I tried for about four hours before
giving up - this part of the excellent Allegro docs is horribly obscure and
unclear.

SUMMARY:

The object is a binary data type object ("DATA") - I want to store an XDIM
and YDIM property for this object using the grabber, and then access these
XDIM and YDIM properties inside my program, just like the grabber access
them when I reload the datafile into the grabber - the grabber source is too
complex I do not understand it (believe me, I have looked 'cause it
obviously does EXACTLY what I want - store a custom property value for a
standard Allegro datafile object and then retrieve it later)

How?

Please reply by email if at all possible - fanx!!!
