Is dbExpress for VCL only?  I tried to drag a dbExpress MSSql connection and 
I can't drag it anywhere I have found yet.

Is something busted?  Shouldn't I be able to drag those?  I can drag all the 
BDPs.

Let me clarify that.  I believe I did drag and drop the dbExpress connection 
to a VCL window.

How would I use it on a WinForms?  Is it VCL only?  How do I use dbExpress 
from a web app, both DotNet and not?

Ah Ha!

I finally found a page in the help that had a diagram showing the 
relationship of the different database access objects!

It was here:

From what I understand, dbExpress is only available under VCL.  So, like you 
found in the help diagram, it will work under .NET if you use VCL.NET.  I 
found it to work much better under Delphi 2005 than Delphi 2006.  In fact, I 
had upgraded to D2006 and had to back down to D2005 because of all the 
problems.

One problem is in the IDE.  Because of the new WideStrings support, the 
TSQLConnection's parameters are now WideStrings.  Delphi 2006 IDE 
incorrectly assumes you need the WideStrings unit (you do under Win32, but 
not .NET) and forces it to be added to the uses clause.  You have to remove 
the component from the form or datamodule and create it manually in code. 
There were other issues that arose, but I just moved back to D2005.

Because of this and other frustrations I had, I will probably never do 
dbExpress in VCL.NET again.  I would rather keep the project in Win32 or 
rewrite it using ADO.NET.
