Building a UserForm Dynamically-Can't add code to button

Hi all,

I am attempting to build my first dynamic userform. One problem I am having is probably pretty simple, I just don't know the answer. The second & third questions I will post separately as they are not a priority at this time.

Background:
I am designing a dynamic form so that the end user can establish a set of standard field names for use in standardizing a data processing regimen that they will use for multiple files. The intent is to allow the user to add or delete fields as desired, and have the form refresh/resize itself for a custom number of fields, with the ability to re-run it in the future should they need to. But first it populates with a group of recommended field values found in the dynamically named range called "stdFieldNames", which is column A in a sheet named "Headers" in this workbook.

And for simplicity at this time, I am using a pre-existing (empty) form that resides within the workbook. I am intending to later make the creation of the form itself part of the code--but that's a topic for another question.;)

So:
I have built the UserForm_Activate() procedure within the blank form to automatically build out the textboxes and buttons that will allow the user to modify the list of field names and IT WORKS!

That is, it works until I try to put code behind the first button when it is added to the form. I'm sure the problem is likely syntactical in nature, but I cannot find anything that will point me the right way. If I rem out the lines to write the code for the button, it works perfectly.

I get an error at "Line = .CountOfLines" (See below) The message is "Run-time error '438': Objects doesn't suppoprt this property or method"

Code:
Private Sub UserForm_Activate()
[COLOR=#ff0000]      ' Can this be modified to dynamically create the textboxes in the event that the user creates more (or less) fields?[/COLOR]
      Dim xControl As Control

            .StartUpPosition = 0

            .Left = AppXCenter - (Me.Width / 2)
      End With


End Sub

I am hoping someone out there has a better eye for what I am not seeing or a better brain for what I do not know.

TIA!

Not quite sure how that block of code was throwing an error in the code writing section, but you are correct. This works perfectly.

Once again, your knowledge has given me solid and useful direction as I learn a little more VBA!

Thank you for sharing! Thank you, Thank you, Thank you!

Till the next time, have a great day!

I don't think the problem code is the section you've highlighted, I think the problem actually lies here.
Code:
With objFrm
            .Properties.ScrollBars = fmScrollBarsVertical                    'This will create a vertical scrollbar
            .Properties("Height").Value = 648
            .Properties("Width").Value = 240
            .Properties.ScrollHeight = .InsideHeight * 1.2                   'Change the values as needed
            .Properties.ScrollWidth = .InsideWidth * 9                       ' Works fine
            .Properties.StartUpPosition = 0
            .Properties("Top").Value = AppYCenter - (.Properties("Height").Value / 2)
            .Propertied("Left").Value = AppXCenter - (.Properties("Width").Value / 2)
      End With
You have to use Properties for each of the userform's properties including ScrollHeight, ScrollWidth etc.

This works for me.
Code:
Option Explicit
Public Const vbext_ct_MSForm = 3

Dim c As Range
Dim topPos As Long
Dim xControl As MSForms.Control
Dim objFrm As Object
Dim clTXT As MSForms.Control
Dim Btn As MSForms.CommandButton
Dim newFieldNo As Long
Dim txtBox As MSForms.TextBox
Dim ctlLabel As MSForms.Label
Dim AppXCenter As Long
Dim AppYCenter As Long
Dim I As Long
Dim J As Long
Dim Line As Long


Sub CreateFieldSetupForm()

    Set objFrm = ThisWorkbook.VBProject.VBComponents.Add(vbext_ct_MSForm)

    objFrm.Properties("Width").Value = 240

    ' Define the top label position and contents.
    Set ctlLabel = objFrm.Designer.Controls.Add("Forms.Label.1", "Label1", True)
    ctlLabel.Caption = "These will be your standard field names. Click 'OK' to accept them as they are, or replace with your preferred field names and click 'OK'."
    ctlLabel.Height = 138: ctlLabel.Width = 204: ctlLabel.Left = 6: ctlLabel.Top = 18: ctlLabel.Font.Size = 11: ctlLabel.TextAlign = fmTextAlignCenter: ctlLabel.Font.Name = "Callibri"

    Set ctlLabel = Nothing        ' Clear the label object

    With objFrm

        ' Build out the text boxes for however many rows are in the dynamic range 'stdFieldNames'
        ' This will be the starting position for the first textbox:
        topPos = 90
        For Each c In Sheets("Headers").Range("stdFieldNames")

            Set txtBox = objFrm.Designer.Controls.Add("Forms.TextBox.1", "Text" & c.Row - 1)
            txtBox.Name = "TextBox" & c.Row - 1
            If txtBox.Name <> "TextBox1" Then topPos = topPos + 18 Else: topPos = 90
            txtBox.Height = 15.6: txtBox.Width = 138: txtBox.Left = 36: txtBox.Value = c.Value: txtBox.Top = topPos

            ' Exit loop when all existing field names have been read and text boxes created.
            If c.Row = Sheets("Headers").Range("stdFieldNames").Rows.Count Then newFieldNo = c.Row + 1: Exit For
        Next c


        ' Button to accept changes is 24 points below last field.

            .InsertLines Line + 2, "MsgBox ""Hello!"""
            .InsertLines Line + 4, "End Sub"
        End With
    End With

    Set Btn = objFrm.Designer.Controls.Add("Forms.CommandButton.1")
    
    With Btn
        .Caption = "Add Field": .Height = 24: .Width = 78: .Left = 66: .Top = topPos

    ' show newly created form
    VBA.UserForms.Add(objFrm.Name).Show

If Excel says you have links but you can't find them, go to Formulas, Name Manager. Look for old links to dead workbooks & delete.
