Writing codes in Microsoft Access

[Freddie1001]

Good day MMcCarthy
Please I'm a beginner in Access programming.
I'm developing a small application for my office use.
On the Form, I would like to have some fields diabled based on selection from a combo.
For instance, immediately after selecting Cars in a combo, the fields Tonnage and AuxTank should be disabled; preventing user from entering values in those two fields.
Thank you for your support.

Add code to the after update event of the combo. Something like this

Private Sub Me.comboname_AfterUpdate()

Select Case Me.comboname

Case "Cars"
Me.Tonnage.Enabled=False
Me.AuxTank.Enabled=False

Case "Lorries"
Me.Tonnage.Enabled=True

...

Case Else
'anything not covered in the above goes here

End Select

End Sub

If you have a lot of possible variations, a better way of doing this is by using the Tag property.
Give all the controls that you want to disable the same tag value e.g. A

Then in the after update event, loop through the controls and set Enabled=False for all the fields where tag.value=A
