I have a column in my access database table called "Lines", and I need it to be an array type somehow so that for each record in the table I can have multiple "Lines" and for each "Line" I can store an X1, Y1, X2, Y2.  Also, how would I use a select statement and update statement from visual basic to access and update that field?  I know I could just create a whole new table to do this for me, but would perfer not too.  I don't know a lot about access, use it rarely, so I'm sure is something beyond the basics I know to accomplish this.

Thanks, Jebus

I just found the menu thing insert a subdatasheet.  Is this along the lines if something I could use?  How does it work and how would I implement it in my vb project to make it work?  Or is it completely unrelated?

Thanks Jebus

How about adding them to the field seperated by a carraiage return:

' add a refence to Microsoft ActiveX Data Objects Library:

Dim DataBase As String
Dim cn As ADODB.Connection
Dim rs As ADODB.Recordset
DataBase = "C:\MyDataBase"

' open Database Connection
Set cn = New ADODB.Connection
cn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source='" & DataBase & "'"
cn.CursorLocation = adUseClient
cn.Open

' open recordset
Set rs = New ADODB.Recordset
rs.Open "Select * From MyTable", cn, adOpenKeyset, adLockOptimistic

' add new record to Table
rs.AddNew
rs.Fields("Lines").Value = X1 & vbCr & X2 & vbCr & Y1 & vbCr & Y2
rs.Update

' update current record
rs.Fields("Lines").Value = X1 & vbCr & X2 & vbCr & Y1 & vbCr & Y2
rs.Update

' close recordset
rs.Close
Set rs = Nothing

' close connection
cn.Close
Set cn = Nothing

I would like to try using this subdatasheet thing.  I have a table called "Jobs" in which I have a subdatasheet called "Walls"  In Walls I have my WallID, X1, Y1, X2, Y2 columns.  So all I need now is to write my sql string to be able to select and update things from the Walls table for each record in Jobs.

Thanks Jebus

Well, I figured it out on my own.  I just made another table for Walls and used the relations thing in access.  I then used a normal select statement with a where JobID=blah  thing.

Thanks, Jebus
