 Delphi connection to Oracle DB

        Hello folks.  I'm new to Delphi and had some help from my local
programmer here but we are stumped.  Here's the problem.  I am running
Delphi 3.0 just installed on my Windows NT 4.0 WS and I have an Oracle 7.2
Database running on a HP-UX box.  On my NT WS, I have installed the Oracle
client 7.3.3 and can run SQL+ and connect via ODBC.  I have created a simple
form on Delphi that will access this Database and it seems to work fine when
I'm in program mode, meaning that once I set the TQuery or TDatabase to
true, data shows up on the DBGrid.  It does prompt me to type in my userid
and password on the Oracle database and it works.  The problem arises when I
compile/run the program.  It comes up with the login window for the
Database, which I want it to do, but once I type in the password with the
valid userid, the system comes up with an error:

        access violation at 0x4be41a9: read of address 0xfffa17c0 83 3A
        00 74 63 E8 39 10 00 00 64 8B

which I have no idea what this means.  We have tried everthing that we could
think of.  We thought the database name was incorrect and maybe the
Tdatabase modules shouldn't have been in the panels and we decided to move
it to the Form instead and still the same error.  If anyone can help me with
this error message, I would greatly appreciate it.  Please email me at

advance.

Hi there...
Please make sure that your database connection is not active before you
compile and run.
Set all your TQuery's, TTables and TDatabase active property to false. This
should help your problem.
