Hey there, Ken...

One comment and one question:

The code would be shorter if the Imports were done on a project basis, which VB lets you do. Then you don't have to write any of those Imports statements. <g> Very useful for something like the Toolkit which you want to use a lot.

Now the question:

Why not use the Toolkit? I'm seeing a number of people say things like "I only want to use *pure* .NET - as if user created function and class libraries aren't pure .NET". I never saw people in Fox/DOS days say "I won't create my own CityStateZip function because it's not pure Fox".

What's wrong with domain specific functions and classes?

>Ah - OK, I see - I can see where that would be easier for many. I suppose I'm more interested in the object-centric-approach, which is why that doesn't make a lot of difference for me.
>I would also point out that the VB code in your example is, in total, a good bit (percentage wise) longer ;-)

>BTW - thanks for the toolkit - While I don't see myself using it in production, Chuck Urwiler pointed out that it will be a great tool to help in "learning" .NET - i.e. translating from VFP functions to classes. I agree and plan on using it this way.

>>>Kamal - guess I'm missing something here. I can do a "using My.Name.Space" and refer to static class methods the same way I would functions in VFP or as you seem to be describing - i.e. with no class preface. What is the difference between this and what you are saying VB does?
