VBA User Forms videos | Excel VBA Forms Pt 5 - Validating Forms

Posted by Andrew Gould on 31 March 2016

Another aspect of validation is checking that every control on a form has been filled in. This video explains how to loop over the controls collection to check if every textbox has been completed.

Making a  video bigger

You can increase the size of your video to make it fill the screen like this:

View full screen

Play your video (the icons shown won't appear until you do), then click on the full screen icon which appears as shown at its bottom right-hand corner.


When you've finished viewing a video in full screen mode, just press the Esc key to return to normal view.

Improving the quality of a video

To improve the quality of a video, first click on the Settings icon:

Settings icon

Make sure you're playing your video so that the icons shown appear, then click on this gear icon at the bottom right-hand corner.


Choose to change the video quality:

Video quality

Click on Quality as shown to bring up the submenu.


The higher the number you choose, the better will be your video quality (but the slower the connection speed):

Connection speed

Don't choose the HD option unless you have a fast enough connection speed to support it!


Is your Wise Owl speaking too slowly (or too quickly)?  You can also use the Settings menu above to change your playback speed.

This code works for me; however, I have one textbox on my form that is for comments and isn't required to be filled in. How do exempt that textbox from being filled out? Additionally, I also have ComboBoxes that need to be filled in. How do I add them to this logic. TIA

You can check for combo boxes using the same basic technique as for text boxes:

If TypeOf ctl Is MSForms.ComboBox Then

To exclude a specific text box you can test for some unique property which identifies it - its Name property is a good choice. If you have multiple controls you want to exclude from the validation you could enter a value in each control's Tag property, for example NoCheck, then test for that value in your loop. You can do that with nested If statements or by combining logical tests in a single statement:

If TypeOf ctl Is MSForms.TextBox And ctl.Tag <> "NoCheck" Then

I hope it helps!

I got it to work using two separate For each statements. I tried two if statements and an elseif but both of these gave me an error of for without next. I am assuming the only way to turn the fields back to no highlight once the user enters data, before they hit the submit button, is to update each of the fields

It's likely that you had the wrong number of End If statements. Here's the basic structure for a single For Each loop

    Dim ctl As MSForms.Control
    Dim tb As MSForms.TextBox
    Dim cb As MSForms.ComboBox
    For Each ctl In Me.Controls
        If TypeOf ctl Is MSForms.TextBox Then
            Set tb = ctl
            If tb.Value = "" Then
                tb.BackColor = rgbPink
            End If
        ElseIf TypeOf ctl Is MSForms.ComboBox Then
            Set cb = ctl
            If cb.Value = "" Then
                cb.BackColor = rgbPink
            End If
        End If
    Next ctl

You can use the Change event of a text box or combo box to detect when a user enters a value and switch the colour back but yes, you'd need to do this for each control.

First of all, THANK YOU for such brilliant quality videos! Andrew G. is the perfect balance of humor & guru! I have found each of these videos to be engaging, easily relatable and packed full of new information!

Onto my question...

I am building a userform to collect information into a workbook, very very similar to your examples with Films and the gross profits they made. HOWEVER, where your example had 3 input boxes, mine will have over 40 input boxes.

What would your recommendation be for an alternative to doing a similar action for each of the input boxes private subs? That is A LOT of repetiion and risk for missing an update. Is there a way to code the action once, but let it loop through each Private Sub?

Specifcially, I am trying to use the following code from the videos, but I dont want to copy paste and edit this over 40 times. The input boxes are labeled Criteria001 through Criteria045.

Private Sub AddToList_Button_Click()
    If Criteria001.Value = "1" Or Criteria001.Value = "0" Or Criteria001.Value = "x" Then
        MsgBox ProcessorName & "'s scores have been added to the Analyst Workbook."
        Criteria001.BackColor = rgbPink
        Criteria001Label.ForeColor = rgbRed
        MsgBox "You must enter either 1, 0, or x."
        Exit Sub
    End If
End Sub

Hi Candice,

Happy to hear that you've been finding the videos so useful! There certainly is a quicker way to vaildate multiple controls using a For Each loop. We do cover that technique in this video from around the 18:32 mark - this is definitely the approach to take if you hvae 40 text boxes to validate!

Thank you!
