Hi
I'm trying to pass a collection from a .NET DLL to a VB6 app. I get a
error 13 (type mismatch) when I do so. I passed back a boolean variable
without any problems, but when I try the collection I get the error.
As you can see the function does not do anything at the moment, so it
must be some issue passing the collection.
Thanks

Hi,
The vb.net collection is not the same as the vb6 collection.
Microsoft.Visua lBasic.Collecti on is the same as the vb6 collection

Not sure if this will help but:-
1. Your Fetch method takes Integer parameters and you are passing
string data. Use CLng function in VB6 to cast the string (ie: Integers
in .Net are Longs in VB6).
2. Your Fetch method declares the parameters as ByVal when the default
in VB6 is ByRef and again you are NOT casting the strings (ie: add ByVal
to the VB6 call).
Kind Regards,

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
