Hide and/or disable the red X to close a Userform|VBA & Macros|Excel Forum|My Online Training Hub

I have created a spreadsheet to track people who will be attending orientation.  Using VBA I created some userforms hoping to ensure the integrity of the data.  However, what I have found is that if they click the save or update buttons on the form and then ALSO click on the red X it will only save part of the data and the validation I built into the form is worthless.  Is there a way to hide or disable the red X?  The other thing I am so unsure about with VBA is exactly where to put such code to make sure it doesn't interfere with the other validation I am trying to do.  I attempted to upload a sample of the workbook, but the file is too large to attach.  So, here is the VBA code I have currently for adding a new person to the log:

Option Explicit
Private OLTable As ListObject
Private CurrentRow As Long
' This module inserts a new record into the OrientationLog table
Private Sub CommandButtonSave_Click()

' Initialize the OLTable variable
        Set OLTable = ActiveSheet.ListObjects("OrientationLog")

' Error checking
    '   Make sure a first name is entered
        If TextBoxFirstName.Text = "" Then
            MsgBox "Please enter a first name."
            TextBoxFirstName.SetFocus
            Exit Sub
        End If
    '   Make sure a last name is entered
        If TextBoxLastName.Text = "" Then
            MsgBox "Please enter a last name."
            TextBoxLastName.SetFocus
            Exit Sub
        End If
    '   Make sure a orientation dates are entered
        If ListBoxOrientationDates.Text = "" Then
            MsgBox "Please select orientation dates."
                ListBoxOrientationDates.SetFocus
            Exit Sub
        End If
    '   Make sure the Department was entered
        If ListBoxDept.Text = "" Then
            MsgBox "Please select a Department."
                ListBoxDept.SetFocus
            Exit Sub
        End If
    '   Make sure the status is selected
        If ListBoxStatus = "" Then
            MsgBox "Please select the appropriate status."
                ListBoxStatus.SetFocus
            Exit Sub
        End If
   
' Unprotect the sheet so data can be added.
    ActiveSheet.Unprotect Password:="OrientationLog"

' Add a new row to the table and Insert the data into the new row
    ActiveSheet.ListObjects("OrientationLog").ListRows.Add
       
    InsertTableRow OLTable.ListRows(OLTable.ListRows.Count).Range
   
' Sorts the table by orientation date (Descending), last name, first name
    Range("OrientationLog[[#Headers],[Human Resource Specialist]]").Select
    ActiveWorkbook.Worksheets("Orientation Log").ListObjects("OrientationLog").Sort _
        .SortFields.Clear
    ActiveWorkbook.Worksheets("Orientation Log").ListObjects("OrientationLog").Sort _
        .SortFields.Add Key:=Range("OrientationLog[Orientation Day 1]"), SortOn:= _
        xlSortOnValues, Order:=xlDescending, DataOption:=xlSortNormal
    ActiveWorkbook.Worksheets("Orientation Log").ListObjects("OrientationLog").Sort _
        .SortFields.Add Key:=Range("OrientationLog[[Last]]"), SortOn:= _
        xlSortOnValues, Order:=xlAscending, DataOption:=xlSortNormal
    ActiveWorkbook.Worksheets("Orientation Log").ListObjects("OrientationLog").Sort _
        .SortFields.Add Key:=Range("OrientationLog[First]"), SortOn:=xlSortOnValues _
        , Order:=xlAscending, DataOption:=xlSortNormal
    With ActiveWorkbook.Worksheets("Orientation Log").ListObjects("OrientationLog") _
        .Sort
        .Header = xlYes
        .MatchCase = False
        .Orientation = xlTopToBottom
        .SortMethod = xlPinYin
        .Apply
    End With
   
' Protect the worksheet.
    ActiveSheet.Protect Password:="OrientationLog", AllowFiltering:=True
   
' Close the UserForm
    Unload Me
       
End Sub

' Insert Instructions
Private Sub InsertTableRow(TableRow As Range)

    With TableRow
   
        ' Insert the data from the form into the table
        .Cells(1, 2).Value = ListBoxHRStaff.Value
        .Cells(1, 3).Value = ""
        .Cells(1, 4).Value = ListBoxPayroll.Value
        .Cells(1, 5).Value = TextBoxKronosBadge.Value
        .Cells(1, 6).Value = TextBoxLastName.Value
        .Cells(1, 7).Value = TextBoxFirstName.Value
        .Cells(1, 8).Value = TextBoxMiddleName.Value
        .Cells(1, 9).Value = TextBoxPhoneNumber.Value
        .Cells(1, 10).Value = ListBoxGamComCont.Value

        .Cells(1, 14).Value = ListBoxTitle31Health.Value

        .Cells(1, 16).Value = ListBoxDept.Value
        .Cells(1, 17).Value = TextBoxDivFac.Value
        .Cells(1, 18).Value = TextBoxLocation.Value
        .Cells(1, 19).Value = ListBoxStatus.Value
        .Cells(1, 20).Value = ListBoxExmpt.Value

        .Cells(1, 30).Value = TextBoxDelayedOrientation.Value
        .Cells(1, 31).Value = TextBoxRecruitSource.Value
       
    ' If one day orientation is selected, then set day2 and day3 attendance to N/A
        If ListBoxRehire.Value = "Yes - 1 Day Orientation" Then
            .Cells(1, 26).Value = ""
            .Cells(1, 27).Value = "N/A"
            .Cells(1, 28).Value = "N/A"
        Else
            .Cells(1, 26).Value = ""
            .Cells(1, 27).Value = ""
            .Cells(1, 28).Value = ""
        End If
   
    End With

End Sub
' This closes the userform without saving anything
Private Sub CommandButtonCancel_Click()
    Unload UserFormAddNew
End Sub

Again, I am very new to VBA and have pieced this together through different blogs and posts, so if you have suggestions for streamlining any of this, I'm open to that feedback as well.

Thank you all for your help!
