Hi



I have a listbox called lstTableNames, which returns a list of all of the tables in my database. When I select the table in the list box, I want a combo box to return all of the fields in the selected table. For example, if I select “company” (a table in my database) from the listbox, I want the combo box to populate itself with the fields in that table (such as “name”, “Address1”, “Address2”, etc.)



Is there an easy way of achieving this?



Here’s my code to populate the list box…



'Form Load

Private Sub MyForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

ConnString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\\svr1\database\MyDatabase.mdb;Persist Security Info=False" 'DataBase Connection DBConnection.ConnectionString = ConnString

DBConnection.Open()

Call FillTableNames()

DBConnection.Close()

End Sub



'Fill the listbox with the table names in my database

Private Sub FillTableNames()

Dim DBSchema As New OleDb.OleDbSchemaGuid

Dim DBTableNames As New DataTable



DBTableNames = DBConnection.GetOleDbSchemaTable(DBSchema.Tables, New Object() {Nothing, Nothing, Nothing, "TABLE"})



'Filling the ListBox With TableNames and DataSet Table Records

Dim DBTableRow As DataRow

Dim SQLString As String

lstTableNames.Items.Clear()

For Each DBTableRow In DBTableNames.Rows

lstTableNames.Items.Add(DBTableRow.Item(2))

'Index 2 Specifies TableName Column in the Schema Record

SQLString = "Select * from " & CStr(DBTableRow.Item(2))

Dim DBDataAdapter As New OleDb.OleDbDataAdapter(SQLString, ConnString)

DBDataAdapter.Fill(DBDataSet, CStr(DBTableRow.Item(2)))

Next

End Sub



Thanks
