I have created my own set of ADO Controls to over come some of the problems
I encountered with ADO Express.

The main part of what you must do is import the typelib of the ADO library
(msador15.dll, something like that).
This will give you all the access you need to ADO.

From there it's up to you to do with it as you wish.

I have found some trouble, when i have write this piece of code:

  TCOM_Connection Con;
  TCOM_Recordset Tables = CoRecordset::Create();

  Tables1 = Con->OpenSchema(adSchemaTables, TVariant(EmptyParam),
TVariant(EmptyParam));

and i get an errore message because the OpenSchema method cannot
return a TCOM_Recordset object but a _Recordset object.
Could someone help me?
Thanks
Stefano

Hey Olle Thanks for the post... This looks like exactly what we need to be
able to use ADO... but I ran into trouble.

I tried the process at the webpage given -- the directions seem to be for
BCB4, but I think I did what was required.  I wanted to add ADO 2.6 to my
project so I used the Project|Import Type Library options of the BCB5 main
menu. I selected Microsoft Activex Data Objects 2.6 Library from the list of
options. Then I clicked install and BCB5 tried to build the import library.

We got the following errors before the compile terminated. Anybody have any
ideas as to what we're doing wrong? These errors occurred regardless of
whether we checked the Generate Component Wrapper check box or not.

[C++ Warning] ADODB_OCX.h(643): W8022 '_fastcall TRecord::GetChildren()'
hides virtual function '_fastcall TComponent::GetChildren(void (_fastcall *
(_closure )(TComponent *))(TComponent *),TComponent *)'
[C++ Error] ADODB_OCX.cpp(131): E2034 Cannot convert 'TVariant' to 'long *'
[C++ Error] ADODB_OCX.cpp(131): E2342 Type mismatch in parameter 'Options'
(wanted 'long *', got 'TVariant')
[C++ Error] ADODB_OCX.cpp(139): E2034 Cannot convert 'TVariant' to 'long *'
[C++ Error] ADODB_OCX.cpp(139): E2342 Type mismatch in parameter 'Options'
(wanted 'long *', got 'TVariant')

Any ideas what I'm doing wrong?

Thanks Bill A.
