Create Acess Database, Tables and Fields through VB by s2001
Posted: 3 Jan 02

Hi all;

I am writing this FAQ because I have seen my question concerning creating Access Database, tables and field
and populating them. Use this sample code to work around.

option explicit
Private wrkDefault As Workspace
Private dbsNew As Database
Private tdfNew As New TableDef
Private cnn As New ADODB.Connection
Private cmd As New ADODB.Command
Private strcnn As String
Private rs As New ADODB.Recordset
Private sDataBaseName As String

Private Sub CreateDB()
On Error GoTo err

sDataBaseName = "c:\NewDB.mdb"
Set wrkDefault = DBEngine.Workspaces(0)
Set dbsNew = wrkDefault.CreateDatabase(sDataBaseName, _
    dbLangGeneral, dbEncrypt) 'Create New DataBase
Set dbsNew = wrkDefault.OpenDatabase(sDataBaseName, True, False) 'open the created Database
Set tdfNew = dbsNew.CreateTableDef("NewTable")  'Create Table

With tdfNew
  .fields.Append .CreateField("NewField", dbtext) 'Create a new field with text as data type
End With

dbsNew.TableDefs.Append tdfNew 'add the table to the DB
dbsNew.Close 'close database
    If err.Number = 3204 Then 'DB exists
        Kill sDataBaseName
    End If
End Sub

Private Sub populateDB()
cnn.ConnectionString = "ODBC;DBQ=" & sDataBaseName & ";UID=;PWD=;Driver={Microsoft Access Driver (*.mdb)}"
Set rs = New ADODB.Recordset
strcnn = "SELECT * FROM  NewTable"
rs.open strcnn, cnn, adOpenDynamic, adLockOptimistic
rs.fields("NewField").Value = "Hello"
' To read from the DB into say a textbox named text1
' text1.text=rs.fields("NewField").Value

Set rs = Nothing

MsgBox "Done. Database can be found at " & sDataBaseName, vbInformation + vbOKOnly

'******--------PS: Referance ADO 2.5 and DAO 3.6***********-

End Sub
