Pelase help if you can. I have a deadline, and have spent hours wrestling with this problem.
My program populates a collection with over 1000 product objects, using the product ID as the key for each Product object. The product ID is also stored in a variable in the product object. Each product has a unique ID.
As each product is added to the collection, the product ID is being written to a text file, just for the sake of debugging, which proves that the value for the iD is correct. Also, all 1003 products are added to the collection with no errors.
Here's where the problem comes in: Immediately after building the collection, I use a loop to get the product IDs for all the 1003 products, and the exact same product ID is returned for all 1003 of them. The ID that is being returned happens to be the ID of the last product added.
But I KNOW they don't all have the same ID, and I have a text file to prove it. And they certainly don't have the same key, because that's impossible. And the key is the ID.
Is there some trick to loopig through a collection? I've looked at code on the Web, and I don't see anything special that needs to be done. Is there some kind of cursor that gets stuck on 1 item and won't iterate?
Here's my code:
-----------------------------------------
Code to add the product to the collection:
-----------------------------------------
'inside a loop
objProductCollection.Add(objProduct, objProduct.getProductNumberBasic())
'NOTE: If the product IDs were all the same, that above line of code would crash, so we know they are unique. So why doesn't the code below reflect that?
-----------------------------------
Code to loop through the collection:
-----------------------------------
For i = 1 To objProductCollection.Count()
My.Computer.FileSystem.WriteAllText("C://getProductNumberBasic.txt", objProductCollection.Item(i).getProductNumberBasic() & vbCrLf, True)
Next
-----------------------------------------------
I also tried the above loop with a For Each, with no success.
This seems impossible, but it's happening. Can someone pelase set me straight on this?
