One last question for today.  I have been looking for the answer to this 
for the last hour and I can't find it.

In the old days (Delphi 5) you could add an icon to a component that 
would be displayed next to the component on the tool bar.  You did this 
by putting the icon in a .DCR file.  What is the equivalent for a 
VCL.Net component in Rad Studio 2007?

Add a {$R} directive to a unit in your design time package linking in
the bitmap:

{$R 'MyNamespace.MyComponent.bmp'}

The bitmap name should be the full .NET component name.

I have created a 16x16 256 colour bitmap.  The namespace for my 
components is LNSSoftware.  The class name for the component is 
TLNSEdit.  I named the bitmap LNSSoftware.TLNSEdit.bmp.  I added

{$R LNSSoftware.TLNSEdit.bmp}

just after the uses clause in the module which contains the TLNSEdit 
class.  I rebuilt the DLL.  The icon does not appear on the tool bar.

I also tried adding {$R LNSSoftware.TLNSEdit16.bmp} and {$R 
LNSSoftware.TLNSEdit32.bmp'}.  That didn't help either.

I must be doing something stupid but I can't figure out what it is.

Any suggestions?

Never mind.  Removing the namespace from the front of the bitmap name 
made it work.  Don't ask me why though.

Did you add the resource to the Project or the Unit? If you took the unit it 
might be logical...

I added the resource to the unit.  I think that the problem arose 
because I gave the project a default namespace of LNSSoftware, but I 
didn't name the unit LNSSoftware.LNSEdit, rather just LNSEdit.  I 
haven't had a chance to experiment to see if that is indeed the problem 
though.
