Assign code to a button created dynamically - vba

Question

I'm trying to get a button I've created dynamically on an excel userform form to run a macro called transfer which I've written in Module 1 of the "Modules" section of my project.
Below I've pasted the code I've written so far in the userform which actually manages to create the Transfer to Sheet button in the frame (which I've also created dynamically) but for some reason, when I run VBA I get a 438 error message saying that Object doesn't support this property or method.
Can anybody tell me how I can resolve this?
Here's the code:
Dim framecontrol1 As Control
Set workitemframe = Controls.Add("Forms.Frame.1")
With workitemframe
.Width = 400
.Height = 400
.Top = 160
.Left = 2
.ZOrder (1)
.Visible = True
End With
workitemframe.Caption = "Test"
Set framecontrol1 = workitemframe.Controls.Add("Forms.commandbutton.1")
With framecontrol1
.Width = 100
.Top = 70
.Left = 10
.ZOrder (1)
.Visible = True
.Caption = "Transfer to Sheet"
End With
framecontrol1.OnAction = "transfer"

Answer 1

Here is an example. Please amend it to suit your needs :)
This example will create a command button and assign code to it so that when it is pressed, it will display "Hello World".
Paste this code in the click event of a command button which will create a new command button dynamically and assign code to it.
Option Explicit
Dim cmdArray() As New Class1
Private Sub CommandButton1_Click()
Dim ctl_Command As Control
Dim i As Long
i = 1
Set ctl_Command = Me.Controls.Add("Forms.CommandButton.1", "CmdXYZ" & i, False)
With ctl_Command
.Left = 100
.Top = 100
.Width = 255
.Caption = "Click Me " & CStr(i)
.Visible = True
End With
ReDim Preserve cmdArray(1 To i)
Set cmdArray(i).CmdEvents = ctl_Command
Set ctl_Command = Nothing
End Sub
and paste this code in a class module
Option Explicit
Public WithEvents CmdEvents As MSForms.CommandButton
Private Sub CmdEvents_Click()
MsgBox "Hello Word"
End Sub

You need to add the code to the UserForm programatically. I used my code from this vbax article as the reference
The code below:
Runs from a normal module
Adds the button to a UserForm called UserForm1
Adds this code to the Userform for a Click Event
Private Sub CommandButton1_Click()
Call Transfer
End Sub
VBA from normal module
Sub AddToForm()
Dim UF As Object
Dim frameCOntrol1 As Object
Set UF = ActiveWorkbook.VBProject.VBComponents("UserForm1")
Set frameCOntrol1 = UF.designer.Controls.Add("Forms.CommandButton.1")
With frameCOntrol1
.Width = 100
.Top = 70
.Left = 10
.ZOrder (1)
.Visible = True
.Caption = "Transfer to Sheet"
End With
With UF.CodeModule
.InsertLines 2, _
"Private Sub " & frameCOntrol1.Name & "_Click()" & Chr(13) & _
"Call Transfer" & Chr(13) & _
"End Sub"
End With
End Sub
