	Hi, 

	First of all, sorry about my bad english. 

	I'm trying to do a cgi in C to run in IIS, so, it's a console
application, and I have to use Borland C++.

	The cgi should recv data from a web page and record it into a SQL
Database (MS-SQL).

	I'm trying do to it with ADO.

	I create one TADOConnection, one TADOQuery and two
TComponent.

---------------
TADOConnection *ADOConnection1;
TADOQuery *ADOQuery1;
TComponent F_ADOQuery;
TComponent F_ADOConnection;
---------------

	The ADOConnection I started in a function called Abre_DB(), that
runs from main().

--------------
 CoInitialize(NULL);
 ADOConnection1 = new TADOConnection(F_TADOConnection);
 ADOConnection1->ConnectionString = "..."
 ADOConnection1->LoginPrompt = false;
 ADOConnection1->Open();

....
---------------

	It's fine, works ok.

	But when i try to start ADOQuery1 in a function called Grava_DB(),
that runs from main() too, after the Abre_DB(), my program crash.

---------------
ADOQuery1 = new TADOQuery(F_TADOQuery);
---------------

	I don't know what do to...

	Thanks for everyone.. and sorry again about my bad english.

Tiago,

you may have a look at "Creating Web Applications with C++Builder 4 and 5"
article at
http://www.cbuilderzine.com/features/2000/06/cb200006ne_f/cb200006ne_f.asp
It's quite good, as for me and may be of some use for you...

   Alexei.
