In MS Access I have a Form being displayed from a Menu.  If the Form Dataset doesn't have any data it, it displays a blank form.

How do I display the form in say 'Add' Mode?

I have a Button on the Form that I want to be able to click to execute an Event Procedure that loads the Dataset from an MS Excel File.

Set the form property [allow additions] to true. You can either set the form to always allow additions by setting it as a property of the form while in design mode, or dynamically during the Form_Open event, depending on the state of the underlying datasource.

You can do this in the Form_Open event
Private Sub Form_Open(Cancel As Integer)
If Me.RecordsetClone.RecordCount = 0 Then
Me.AllowAdditions = True
Else
Me.AllowAdditions = False
End if
End Sub

Open in new window


Or, you could cancel the Form_Open event and pop up a different form that just contains your button.
Private Sub Form_Open(Cancel As Integer)
If Me.RecordsetClone.RecordCount = 0 Then
Cancel = True
DoCmd.OpenForm "ButtonForm"
End If
End Sub

Open in new window


Your button form can then load the data to your table from Excel and open your original form with the new data loaded.

" have a Button on the Form that I want to be able to click to execute an Event Procedure that loads the Dataset from an MS Excel File. "

...Then why open a "blank" form at all...?

You can select the datasource before you open the form, then just open the form with the data displayed.

Not sure why the extra steps of opening the form empty, seting it to "add mode" then selecting a datasource, ...then displaying all the data, ... is needed...?
(BTW "add Mode" is only needed if you are "manually" adding records, ...in your case you are simply picking a recordsource, ...so in this case, "add mode" is not really needed as far as I can tell)

In other words, ...can you take a step back and explain what your ultimate goal here is, ...in case there is a simpler solution...?

You could change the form to a main form holding a subform.

The main form will be unbound (no recordsource) and have the button to load the dataset into the subform.
The subform will be bound to your current data source and could be a simple DataSheetView form.

When no records, the subform will be blank (empty) but the main form will live.

This solution (first part) I believe is the best as it directly addresses my original requirement.
However thanks for the other suggestions.
