VBA -Identify blank fields for user form before submitting -Force User to add data

Hello all
I have created a User form which is working . I need assistance with VBA code that creates an error message if any of the fields are left blank when they active the "Send "or Save"button .

Ideally for each text box or combo box that is blank .It is my hope that the blank field could be highlighted in a colour and an error message alerting that info is required and cant submit without adding text or selection
I haven't been able to find this info in the forums , possibly using incorrect terminology.

I though that I could omit this process but I have users that continually missing steps and getting agro . I think its the User they feel its my form....Anyway I would like to force Users to enter into all fields

I appreciate that my coding is not elegant but at least it is functional :yes
Hoping someone can provide guidance and education on this
Appreciation and thanks in advance

Code:

add this function to your form

Code:

---

Function CheckFormControls() As Boolean
    Dim oCtl As MSForms.Control
   
    CheckFormControls = True
    With Me
        For Each oCtl In .Controls
            With oCtl
                If TypeName(oCtl) = "TextBox" Then
                    If .Text = "" Then
                        CheckFormControls = False
                        .BackColor = vbRed
                    Else
                        .BackColor = &H80000005
                    End If
                ElseIf TypeName(oCtl) = "ComboBox" Then
                    If .ListIndex = -1 Then
                        CheckFormControls = False
                        .BackColor = vbRed
                    Else
                        .BackColor = &H80000005
                    End If
                End If
            End With
        Next
    End With
End Function

---

Add this code when you need to check for validity at the top of your button code (your SEND and SAVE buttons)

Code:

---

    If Not CheckFormControls Then
        MsgBox "Please correct error"
        Exit Sub
    End If

---

In addition

1. You might consider making fields like Action, Gender, etc. option buttons instead of dropdowns

2. If you exit TIME OF APPPT (which is misspelt) with it blank, you get a Type Mismatch error

Hey Jwan and Paul
Looks like that this has done the trick .Whhoooohoooo ! If the Red is not enough to alert them, then I am not sure what will. Hoping all will go well on Monday when I take to work to try and check file transfer to network spreadsheets
Paul ahh nuts no one has even recognize the spelling error . Thanks for alerting me to the fact ! I hadn't thought of radio buttons . Is there an advantage and how would the code go if they were radio buttons i.e if there were no gender , action selected . Just curious and good for my education.
Thank you both for your assistance its really appreciated . Now no one can say " I filled the form out fully its your form !'

Dropdowns could work, but the way I like to do it is to use Option Buttons in a Frame if there is a fixed number of choices defined in advance and only one can be selected

e.g.

( ) Male
( ) Female

User selects one, and the other(s) are cleared

Hello
Before anyone says i cross posted let me explain . I was not able to get to this site at all , and posted on another site . I did try to indicate that had another request in but didnt fully explain ( on other site)
I understand that cross posting causes problems and wasn't my intention and am aware of the rules . I appreciate all assistance however I was not sure how long the restriction to VBA express would last .
However it did provide me with two excellent solutions.
i hope for your understanding in this instance

Code:

Sub M_snb()
  For Each it In Controls
      Select Case TypeName(it)
      Case "TextBox", "ComboBox"
        it.BackColor = vbRed + 250 * (it.Value = "")
      End Select
    Next
End Sub

@snb, thank you for the code. Very nice!
