Command button should be disable once user form is open

What error?
You might use code like

Private Sub UserForm_Activate()
    Me.ProceedButton.Enabled = False
End Sub

Hi geliedee

Add this Code to the UserForm Module

Private Sub UserForm_Activate()
   Me.CommandButton2.Visible = False
End Sub

Modify this Code in the UserForm Module

Private Sub CommandButton1_Click()

   Dim ws           As Worksheet
   Dim ID           As String
   Dim ID2          As Range
   Dim IDRow        As Long

   Set ws = Sheets("data base")

   ID = TextBox1
   Set ID2 = ws.Range("G:G").Find(what:=ID, LookIn:=xlValues, lookat:=xlWhole)

   If ID2 Is Nothing Then

      MsgBox "This ID does not appear in the data."

      Exit Sub

   Else

      IDRow = ID2.Row
      Me.CommandButton2.Visible = True '<---Add this Line of Code
   End If

   TextBox2 = ws.Cells(IDRow, 7)
   TextBox3 = ws.Cells(IDRow, 1)
   TextBox4 = ws.Cells(IDRow, 3)
   TextBox5 = ws.Cells(IDRow, 8)
   TextBox6 = ws.Cells(IDRow, 9)
   TextBox7 = ws.Cells(IDRow, 11)
   TextBox8 = ws.Cells(IDRow, 6)
   TextBox9 = ws.Cells(IDRow, 4)



End Sub
