VB ODBC connection to Postgresql, DAO,ADO,RDO,DSN???

I was very pleased today, to be successful in connecting to the windows postgresql server across our simple p2p connection. (It all had to do with turning off the windows fire wall, after folks here helped me with the .conf ip address settings, and listening).  What is nice is that I have sygate free fire wall, which simply pops up and asks me if I want to allow the postgres connecting activity. So I may connect and still have a firewall.

 

Now, the next phase of my problem, to make something useful happen.  I can connect like a breeze with rekall, and edit tables, BUT, I havent the foggiest notion how to write a python script in rekall to do what I really want to do with my tables.

 

I dont really understand how rekall will help folks, if they dont have demo examples to do the sort of thing i am attempting.

 

IF, we had money at work, and could afford Access, then I think I would be all set, because I see how I can do a lot in Access VBA. But we cant afford to get it at work. I happen to have it at home, because it came with my Dell.

 

Now I DO have a copy of Visual Basic 6.x and I can easily connect to Postgres with the application wizard, and data aware controls.  But what I really want to be able to do is to have a simple form, with a button, and be able, within the script of that button, to do sql passthrough to postgres, and then manipulate the rows returned to me within the VBA.

 

BUT, it is very hard for me to discover the precise grammar for establishing such a simple connection.   Below, I am posting what I have collected from google of snippets which SEEM like the might do what I want....  But if anyone has a working examle for me, I would be most grateful.  Or if you know an easy way for me to do what I want in some kind of Pearl for windows.  I dont need a form painter with navigation buttons.  What I need is a script that I can put into a look, to look for a certain value in a table,..... wait for a few seconds, look again, and when it FINDS that row with that field value,... then do some things, delete that record or mark it somehow... and go back into more waiting and looking, until the next row/field value appears.  It could be selecting on a very small table with just a few rows.  THe idea is that another workstation would add a row to the table which would cause THIS workstation to read it, and display something on the screen.   So... take a look below, and you will see the sort of thing I am trying to do.

 

I think if I had Powerbasic or Realbasic, then perhaps I could more easily do what I want, but I just dont have the money right now to run out and buy a lot of things.   I also have Visual FOxpro version 5, and I thought I could work with that, but, it is having trouble connecting to postgres via odbc...

 

- Thanks
