Collections: The Revenge

OK, so, thanks to you smart guys, I have my collection items in the
combo/list boxes. Now, when I pick these items, I want to hit a button and
compare the properties.

Logically, here's what I'm thinking. Code wise this obviously isn't
perfect, but I'm going for process here.

for each property of me.list1
if property(me.list1)<>property(me.list2) then
put me.list1.property.name in textbox1 with value and
put me.list2.property.name in textbox2 with value
end if
next property.

So I'd wind up with two boxes next to each other with a list of properties
that are different between the objects. Then I will build a thumbbar that
scrolls both text boxes so the user can compare line by line easily.

The problem is that each collection that I've put into the lists has
different properties, some more than others. Is there a way to scroll
through the properties of an object without knowing what kind of object it
is until scrolling time?

Thank you in advance!

James,
how about;

for each property1 in list1
for each property2 in list2
if property1.name = property2.name then
if property1.value <> property2.value then
put property1.name & " " & property1.value in textbox1
put property2.name & " " & property2.value in textbox2
end if
end if
next property2
next property1

Hi James,

You probably need to create a dictionary of Objects and the properties which
each one can have.

I've done it by creating a key - say Line
Then for a value a set of comma separated items
eg Line,Layer,LineType,LTScale,Color,etc.
You can then return the value from the dictionary and use the Split command
to put it in an array
Get the array for a second object and split it, then compare the array
components in a dual loop

Hence the program flow would be:
For each object in my collection
Get value from dictionary
Get value from dictionary for each other object n the collection with which
you wish to compare
Split both values
Loop through first list
Loop through second list
Do what you want and exit loop if match found
End second list loop
End first list loop
Get another object

That's fine, but how do I cycle through all the properties of an object? I
don't know what they are because the object picked in list1&2 is of varying
types.

Does that make sense?

I don't know of a Properties collection on an object that would list all the
properties available,
so you may have to manually build a mega selectcase statement to provide a
property list depending on the object

or get a list of all properties of all objects and use an 'on error goto
errhandler' to 'try'/'catch' calling each property in turn
(i don't know off hand if vb has a equivalent of property-available-p like
in vlax)

just a thought

Depending upon what you're storing and how you use it, you might be better
creating a class and having your own object. Its some times easier than
concat/split - ing everything
