Display Access form on open & update textbox *while running other code*

^{Sometimes trying to accomplish the most minor turns into a major headache... I somehow corrupted a database while experimenting to solve this issue. Now I'm really determined to figure this out. (I'll worry about the corrupt DB later!)}

End Goal:

When opening .accdb file, automatically:

1. open form unbound)
2. run code to:
   • get Last Update Date from table
   • display Last Update Date in textbox on form ^{(must be visible to user)}
3. if table data is outdated, run code to:
   • update data in table
   • display Update Progress Message(s) in textbox on form ^{(must be visible to user)}
   • when finished:
     • display Last Update Date in textbox on form ^{(must be visible to user)}

The problem is the goal of (must be visible to user).

I can't get the form to display anything until all the code's finished running, regardless of how I run the code (including: set the form to auto-open with File → Options → Display Form; add an AutoExec macro to call code to open the form and run the update; or, run it manually.)

I've been experimenting with the form's opening events to see if I missed something.

According to the Order of Events documentation:

Working with data on a form

Form and control events occur as you move between records in the form and change data. For example, when you first open a form, the following sequence of events occurs:

Open (form) → Load (form) → Resize (form) → Activate (form) → Current (form) → Enter (control) → GotFocus (control)

At no point does the form visibly update. I've tried adding Me.Repaint and even tried Echo=True and DoEvents but obviously they didn't change anything.

My code for testing:

Private Sub Form_Open(Cancel As Integer)
    txtTest = "Form_Open()": MsgBox "1. Form_Open"
End Sub

Private Sub Form_Load()
    txtTest = "Form_Load()": MsgBox "2. Form_Load"
End Sub

Private Sub Form_Current()
    txtTest = "Form_Current()": MsgBox "3. Form_Current"
End Sub

Private Sub txtTest_Enter()
    txtTest = "txtTest_Enter()": MsgBox "4. txtTest_Enter"
End Sub

Private Sub txtTest_GotFocus()
    Echo True : Repaint : DoEvents
    txtTest = "txtTest_GotFocus()": MsgBox "5. txtTest_GotFocus"
End Sub

Private Sub txtTest_Change()                        : MsgBox "This Does't Run!" : End Sub
Private Sub Form_AfterUpdate()                      : MsgBox "This Does't Run!" : End Sub
Private Sub txtTest_Change()                        : MsgBox "This Does't Run!" : End Sub
Private Sub txtTest_BeforeUpdate(Cancel As Integer) : MsgBox "This Does't Run!" : End Sub
Private Sub txtTest_AfterUpdate()                   : MsgBox "This Does't Run!" : End Sub

The result of opening the form:

_{(Note that the form's Activate and AfterUpdate events and the control's Change, BeforeEvent and AfterEvent events do not fire at all.)}

Theoretically, the form should be visible behind the MsgBox, but neither running the actual update code, nor running a "pause" (loop with DoEvents) doesn't display the form either.

I could swear I've done this in the past without issue but no matter what I do try, the form only displays once all code is finished running.
