provide the description for a single character column in Activi ...

Object and collection initializes.
Tue, 7 Oct 2008 21:00:26 -0500
It seems simple enough to use objects initializers to initialize object
properties and collection intitializers to initialize collection, what I
have not been able to figure out is a way to initialize object properties
and collections at the same time.

so that the user cannot change it's value until I allow them. In a Windows VB

The recommended approach to the none-of-the-above exception?

2. Use existing exception classes where it makes sense (ArgumentException

3. Don't create custom exception types if they d ...
