    Option Strict On

    I have employed a "Singleton mode" of programming for this project.

    I have a class that exposes some properties of the class "Sample" to other
    forms....

    If I set Option Strict On, I get many "Option Strict On disallows late
    binding" errors (see below)

    How might I fix this ?


    Public Class Sample

    Private Shared DInstance As Sample = Nothing
    Private Sub New()

    ' This call is required by the Windows Form Designer.
    InitializeCompo nent()

    ' Add any initialization after the InitializeCompo nent() call.

    End Sub

    Public Shared ReadOnly Property Instance()
    Get
    If (DInstance Is Nothing) Then DInstance = New Sample()
    Return DInstance

    End Get
    End Property

    Public Property TabControlAvail able() As TabControl
    Get
    Return Me.TabControl1

    End Get
    Set(ByVal value As TabControl)
    Me.TabControl1 = value

    End Set
    End Property

    Public Property SelectedTabAvai lable() As TabPage
    Get
    Return Me.TabControl1. SelectedTab
    End Get
    Set(ByVal value As TabPage)
    Me.TabControl1. SelectedTab = value
    End Set
    End Property


    ' These are the rows where the errors are pointing to...
    Sample.Instance .Visible = True
    Sample.Instance .TopMost = True
    Sample.Instance .TabControlAvai lable.SelectTab (strTabPageName )
    Sample.Instance .Show()

      Off hand the one major problem I see is that you don't have the
      Instance shared property declared as a type. Add "As Sample" and see
      if it clears up anything.

          Seth,

          You are too good... it cleared up all errors.

          Thanks,

              /"If"/ you set it on???
              IMHO, you should have this set it on /by default/ (under Tools >
              Options) so that you always get told about this sort of thing.
              Public Shared ReadOnly Property Instance() ???
              I'd have expected the error to be something more like:

              "Option Strict On requires all function and property declarations to
              have an 'As' clause."

              which (a) you're missing and (b) is far more explanatory, as error
              messages go (in fairness, it's probably buried in amongst all the other
              errors).

              Add "As Sample" to your Property and you'll be fine.

                  "Option Strict On requires all function and property declarations to
                  have an 'As' clause."
                  As the OP didn't mention version, I wonder if this is just the VS 2005
                  message - perhaps 2003 warns of late binding on undeclared properties?

                      >>Option Strict On requires all function and property declarations to

                      Yes, there was one of those, but when the "As type" was added it was
                      removed with the rest of the "late binding errors"

                          I believe what Phill means is that errors are often cascading. The
                          root error was the "as type" problem, which caused the others. When
                          debugging it's important to not just focus on a certain error, but on
                          all the errors. If you would have posted all the error messages we
                          would have been able to solve the problem faster.

                          Thanks,
