Updating one form to another form from same database.

Question

Hi, I'm having a problem with my forms. Basically I have one form that adds,deletes,updates transactions that are made when a registered member makes a request. Doing this then gets saved in the database under a transaction table.

I then have another form which then calculates my transactions based on when the member returns the DVD or CD. However, if say for example I wish to delete a transaction record, the form that does the calculation of the fines doesn't update itself.

How can I solve this? If im able to create a refresh button on the fines form would this help and if so how will it work as my form contains 1 combo box , 5 text boxes
and 1 date picker(however the date picker is not linked to the database)?

1)This coding here is to do with "Adding,updating, deleting and saving Transaction":

You can force your delete/refresh by making the delete form modal and creating a sub procedure that will refresh the data in the parent form.

Hi, I figured this out ,I created a refresh button that linked to the database directly.

Here is the coding:

Private Sub btnRefresh_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRefresh.Click
        Dim conn As New SqlClient.SqlConnection("Data Source=CHETS-TOSHIBA\SQLEXPRESS;Initial Catalog=PlanetDiscLibrary;Integrated Security=True")
        Dim da As New SqlClient.SqlDataAdapter("SELECT  member.member_id, trnsaction.trnsaction_id, album.album_id, album.album_name, trnsaction.issue_date, trnsaction.return_date FROM  member INNER JOIN trnsaction ON member.member_id = trnsaction.member_id INNER JOIN album ON trnsaction.album_id = album.album_id", conn)
        Dim dt As New DataTable

        dt.Clear()
        conn.Open()
        da.Fill(dt)
        DataSetFinesTrans1.Clear()
        SqlDAtransFines.Fill(DataSetFinesTrans1, "album")
        bm = BindingContext(DataSetFinesTrans1, "album")
        bm.Position = 0
        cbTID.DropDownStyle = ComboBoxStyle.DropDownList
        conn.Close()
    End Sub

Thanks for replying anyway....
