Trying to add Textboxes to a userform dynamically? - excel

Question

I have code inside a excel workbook that helps me create mass emails to send to users of various programs. I have a userform that pops up and the user populates all the info needed. but that only counts for one app at a time. Can someone share code with me that dynamically adds textboxes to a userform dependant on what checkboxes are ticked ?
In the first frame I have check boxes that indicate what applications are affected, second frame I have option buttons to describe what type of incident and then I would like the textboxes to appear according to what has been ticked.
Any guidance much appreciated as I think this is way too deep for me at the moment
I've reverse engineered this code it adds the boxes I want but I need to be able to populate them with cell data and then use it in the emails:
Option Explicit
Dim SpnColct As Collection
Private Sub CommandButton2_Click()
Dim cSpnEvnt As cControlEvent
Dim ctlSB As Control
Dim ctlTXT As Control
Dim lngCounter As Long
For lngCounter = 1 To 7
Set ctlTXT = Me.Frame7.Controls.Add("Forms.TextBox.1", "Text" & lngCounter)
ctlTXT.Name = "Text" & lngCounter
ctlTXT.Left = 5
ctlTXT.Height = 125: ctlTXT.Width = 280
ctlTXT.Top = (lngCounter - 1) * 125 + 2
Set cSpnEvnt = New cControlEvent
Set cSpnEvnt.SP = ctlSB
Set cSpnEvnt.TXT = ctlTXT
SpnColct.Add cSpnEvnt
Next lngCounter
Me.Frame1.ScrollHeight = (lngCounter - 1) * 17 + 2
End Sub
This added to a class module:
Option Explicit
Public WithEvents SP As MSForms.SpinButton
Public WithEvents TXT As MSForms.TextBox
Private Sub SP_SpinDown()
SP.Value = SP.Value - 1
MsgBox "Spin Down to " & SP.Value
End Sub
Private Sub SP_SpinUp()
SP.Value = SP.Value + 1
MsgBox "Spin Up to " & SP.Value
End Sub
Private Sub TXT_Change()
MsgBox "You changed the value."
End Sub

Updated This is going to be a bit of a long one - step through it see if you understand it. Have changed it to create the textboxes on the CheckBox_Click event but change to the commandbutton if you wish. Any more then this and I think you'll need to start a new question.
I've been doing something similar recently and found that the reason you're having issues is due to the order of loading objects. I unfortunately can't find the link that explains it at the moment (will update if can) but briefly to be able to achieve this you need an additional Class that does the loading of the objects, otherwise the Userform can't see them. This is the kind of solution that I came up with (using your example)
Userform:
Option Explicit
Private WithEvents cControls As EventController
Private Sub cControls_Click(ctrl As CheckBoxControl)
Dim tBox As TextBoxControl
Dim i As Long
Dim NextTop As Long, FrameHeight As Long
For i = 1 To cControls.GetControls.Count
Debug.Print TypeName(cControls.GetControl(i))
If TypeName(cControls.GetControl(i)) = "TextBoxControl" Then
Set tBox = cControls.GetControl(i)
If tBox.TXT.Parent Is Me.Frame7 Then
NextTop = tBox.Top + tBox.Height
End If
End If
Next i
Set tBox = cControls.AddTextBox
With tBox
.Height = 125
.Width = 280
.Left = 5
.Top = NextTop
.TXT.Text = ctrl.cBox.Caption
FrameHeight = NextTop + .Height
End With
If FrameHeight > Me.Frame7.InsideHeight Then
With Me.Frame7
.ScrollBars = fmScrollBarsVertical
.ScrollHeight = FrameHeight
.Scroll yAction:=6
End With
End If
End Sub
Private Sub UserForm_Initialize()
Dim i As Long
Dim cBox As CheckBoxControl
Set cControls = New EventController
' This can be set to a userform or a frame
Set cControls.UserForm = Me
For i = 1 To 8
Set cBox = cControls.AddCheckBox
cBox.cBox.Left = 5
With cBox.cBox
.Top = 5 + (i - 1) * .Height
.Caption = IIf(i = 8, "App Unknown", "App " & i)
End With
Next i
End Sub
Private Sub cControls_Change(ctrl As TextBoxControl)
' This can be handled in the class instead as you were - just doing it in the userform to show the exposing of the event
MsgBox ctrl.TXT.Name & " Change"
End Sub
Private Sub cControls_SpinDown(ctrl As TextBoxControl)
' This can be handled in the class instead as you were - just doing it in the userform to show the exposing of the event
With ctrl.SP
If .Value >0 Then
.Value = .Value - 1
End If
End With
MsgBox ctrl.SP.Name & " Spin Down"
End Sub
Private Sub cControls_SpinUp(ctrl As TextBoxControl)
' This can be handled in the class instead as you were - just doing it in the userform to show the exposing of the event
With ctrl.SP
.Value = .Value + 1
End With
MsgBox ctrl.SP.Name & " Spin Up"
End Sub

Parent.SpinDown Me
' SP.Value = SP.Value - 1
' MsgBox "Spin Down to " & SP.Value
End Sub
' The commented out lines below you can either leave in here, or handle in the Userform
Public Sub SP_SpinUp()
Parent.SpinUp Me
' SP.Value = SP.Value + 1
' MsgBox "Spin Up to " & SP.Value
End Sub
Public Sub TXT_Change()
Parent.Change Me
' MsgBox "You changed the value."
End Sub
The issue is stemmed from that when the Userform is loaded the controls aren't loaded and therefore the Userform hasn't registered that they're something that has an Event. By using the intermediary class the Userform recognises that that class has an Event and we load this statically on initialize of the Userform. We can then add in whatever Controls we want to this Class and the Userform will handle them.
