Um die Textbox10 (Last Entry) 
mit dem Inhalt der letzten gefüllten Zelle aus Spalte A zu füllen,
habe ich die fett markierte Zeile hinzugefügt
Private Sub UserForm_Initialize()
Dim aRow, i As Long
TextBox10 = Cells(Cells(Rows.Count, 1).End(xlUp).Row, 1)
Application.EnableEvents = False
ComboBox1.Clear
aRow = [D65536].End(xlUp).Row
ComboBox1.AddItem "choose Date"
For i = 2 To aRow
ComboBox1.AddItem Cells(i, 1)
Next i
ComboBox1.ListIndex = 0
Application.EnableEvents = True
End Sub
In der Hoffnung geholfen zu habe ...
