hmmm here my guess is you had only one item in your properties collection
and it was accessible under index 0 while tring to access a property under
index 1 was an error... if this is so then your variable name is
misleading...
shouldn't be called pr1 and mean 'property with the index 0'. But I presume
this is just quick test code, and that your production code uses variables
with more meaningful names...

What is the type returned by
    CellSet1->
    Axes->get_Item(1)->
    Positions->get_Item(0)->
    Members->get_Item(0)->
    Properties->get_Item(0);

Is it Property* ? If it is then there is NO difference in the type snippets
posted above...

One was I could see this problem happening is if you were getting
a pointer to a class derived from Property and get_Value() wasn't
a virtual function... but then again this is just a guess...

Try to separate it all into variables... and then trace through the code...
try to call some other Property methods and see if they return the
expected results... (like get_Name() perhaps?)...
