UserControl Let/Get Property as Object

Here's my goal:

Code:

---

Option Explicit
  Private m_txt As TextBox

Public Property Let txt(new_txt As TextBox)
  Set m_txt = new_txt
End Property

Public Property Get txt() As Object
  Set txt = m_txt
End Property

---

Now,... i have tried everything but have not be able to figure out how to:

1. get this Property ("txt") to VB's "Properties" box and
2. get list of all TextBox-es on a Form where my UC is located into "Properties" box where "txt" Property is now shown (from 1.; if possible).

Hope this makes sence.

You use Property Set instead of Property Let :)

That doesn't do anything.

Oh, and both properties must use the same type, ie. Object. You can't use TextBox and Object mixed together.

Yeah, I know. It was a typo :blush:

They are both the same. It still doesn't work.

Humm, I managed to miss the last part of the first post, so now I know what you're trying to do. Nope, you can't get a list to VB IDE properties window. It isn't very easy, I've read of some way to do it but it sounded like it would be just an extra dependency mess.

The best you can do is to define Txt as String, then validate there is a textbox of that same name in ParentControls.

Code:

---

Option Explicit

Private m_Txt As String

Public Property Get Txt() As String
    Txt = m_Txt
End Property

Public Property Let Txt(ByVal NewValue As String)
    Dim Ctl As Object
    NewValue = LCase$(NewValue)
    For Each Ctl In ParentControls
        If TypeOf Ctl Is TextBox Then
            If LCase$(Ctl.Name) = NewValue Then
                m_Txt = Ctl.Name
                PropertyChanged "Txt"
                Exit For
            End If
        End If
    Next Ctl
End Property

Private Sub UserControl_Initialize()

End Sub

Private Sub UserControl_ReadProperties(PropBag As PropertyBag)
    Dim Ctl As Object, NewValue As String
    NewValue = LCase$(PropBag.ReadProperty("Txt", vbNullString))
    For Each Ctl In ParentControls
        If TypeOf Ctl Is TextBox Then
            If LCase$(Ctl.Name) = NewValue Then
                m_Txt = Ctl.Name
                Exit For
            End If
        End If
    Next Ctl
End Sub

Private Sub UserControl_WriteProperties(PropBag As PropertyBag)
    Dim Ctl As Object, NewValue As String
    NewValue = LCase$(m_Txt)
    For Each Ctl In ParentControls
        If TypeOf Ctl Is TextBox Then
            If LCase$(Ctl.Name) = NewValue Then
                PropBag.WriteProperty "Txt", Ctl.Name
                Exit For
            End If
        End If
    Next Ctl
End Sub

Thanks, but that approach is already known to me :)

Can you post the link where have you read about it?

Nope, it is quite a long time ago. Another suggestion that I could give is to use a property page, so you can make a combobox or whatever you want yourself.
