I'm a total n00b to VB, though I don't think it'll be too hard to learn. What I'm wondering about, though, is how I will connect to an ODBC database for read access with it. I'm probably also going to need to connect to an Access db for read and write access, which I am also spectacularly n00bish on. I am creating/administering the Access db right now, but I'd like to write a VB front end so that I don't have to install Access on every machine in the office.
Basically, I'm hoping someone here can point me to some good resources, free or otherwise, that will help me learn what I need to learn or at least serve as a good reference or starting point for my questions. I'll be working w/ VB 6.0, btw.

Use ActiveX Data Objects (ADODB). Really easy. Pretty much what you need is an:
ADODB.Connection - an object that manages your database connection
ADODB.Recordset - your query results
Dim Conn as ADODB.Recordset
Dim Rset as ADODB.Recordset
Set Conn = New ADODB.Recordset
Conn.Open 'use appropriate conection string and such
Set Rset = Conn.Execute("SQL QUERY HERE")
Rset.MoveFirst
While Not Rset.EOF
'do something with your record
Rset.MoveNext
Wend
Conn.Close
Set Conn = Nothing
Set Rset = Nothing
You can leave the database connection open and run all the queries you want with it. Just remember to close it and set it to Nothing to free memory wen you're done with it. Depending on how you conect to the datbase, you may or may not be able to determine how many records are in the resulting recordset without looping through and counting.
