Stock Movements in a Management Program

How to handle the loading and unloading of goods in an Access database, to continue our tutorial on how to create a management program, in particular Calus, 2012, we face the construction of a page with a main part and one of detail.

We continue our program for the creation of the warehouse Calus 2012 seeing how to insert windows to management of loading and unloading goods. Here’s how we create our window, in particular use the main pattern and detail.

Loads
Window to manage the loading of goods

To build this type of window we need a main form that contains a sub-form for details. In addition to fields such as number and date of movement, the main window has to filter the data, here is the VBA code:

Option Compare Database

Private Sub Anno_Change()
    If Not IsNull(Me.Anno.Text) Then
        If IsNumeric(Me.Anno.Text) And Me.Anno.Text <> "" Then
            Dim strDate As String

            strDate = "01/01/" & Me.Anno.Text
            If IsDate(strDate) Then
                Me.FilterOn = True
                Me.Filter = "Data BETWEEN #01/01/" & Me.Anno.Text
                         & "# AND #31/12/" & Me.Anno.Text & "#"
