To refresh a split form called "Form2" when a button is clicked on another form called "Form1", you can use the following VBA code:
Code:
Private Sub CommandButton1_Click()
Forms!Form2.Form.Requery
End Sub
This code assumes that the button you want to click is called "CommandButton1" and is located on "Form1". When the button is clicked, the code will refresh the split form called "Form2".
If you want to refresh the subform within the split form, you can use the following code instead:
Code:
Private Sub CommandButton1_Click()
Forms!Form2.Form!SubformControlName.Form.Requery
End Sub
In this case, "SubformControlName" is the name of the subform control on the split form.
A lot of assumption here, but you should have added more details.
