I am writing an application that uses a custom class which inherits
DictionaryBase so that I can add items with an associated key. When I try to
serialize the object though, I get the following error: The type
BuildingsCollection is not supported because it implements IDictionary. Here
is my class:
Namespace BusinessLogicLayer
<Serializable()> _
Public Class BuildingsCollection

hi! i'm wondering what the differences are between hashtables und
dictionarybases; can both of them store several different types of objects,
each accessible by a string key? currently i'm using a class deriving from a
dictionarybase, because i thought all objects in a hashtable had to be of
the same type; was i wrong? should i switch?
thanks,
mike

Hi,
I am using a SoapFormatter to serialize a class which has a member that is
derived from DictionaryBase.
Everything works fine... I can serialize and deserialize. The trouble I
have is that I need to implement versioning, so I have to implement the
ISerializable interface and provide the GetObjectData function and the
constructor to deserialize the object. When I try to deserialize the member
that is derived from DictionaryBase, I...

I've got some code that i found on the net that helps build a flat file
structure.
It uses an underlying DictionaryBase class, but unfortunately it seems to
have a bug you cannot return the flatfilecolumn based upon the index value,
Is it possible to find the key name at an index position?
' return an instance of a single FlatFileColumn object given its 0-based
index -

just as we can bind the text property of a textbox to a column/field of a
table,
can we do the same for a custom property of a class to a field of a table.
To put it simply, i'd like to have a property cName in a class, which i'd
like to bind
to the Name field/column of a datatable. & when this value changes in the
data table,
i want the value in the cName property to change & automatically i want some
otherthings

I want to create a strongly typed collection and use DictionaryBase
I add a number of objects but when i loop through the list the data is
ordered in a strange maner. How is this possible?
Can anybody tell my why the order gets changed?
Thanks Marc

Hi all,
I want to use DictionaryBase as base class. The search performace
matters lot.
I have used a hashtable in a similar situation.
This class DictionaryBase has a innerhash table so i guess the
performace should be the same.

Hello,
I have two objects implemented with CollectionBase framework, say MyParent
and MyChild.
MyChild object is embedded into MyParent and I need to bind some MyChild
properties via MyParent.
I would like to bind a MyChild property without need to create a property
copy into MyParent just to allow access to the MyChild's property because
this will duplicate my entire code.
