Hi Experts!

Have issue calling SClass:
  Reference to a non-shared member requires an object reference.

Here's part of SClass:

Private m_mcw As MClass

    Public Sub New()
        Try
            m_mcw = New MClass()
        Catch ex As Exception
            Dim exOut As New Exception(blah ... blah, ex)
            Throw exOut
        End Try

    End Sub

Here's MClass:

Public Class MClass
    Private m_conCustom As SqlConnection
    Private m_cmdCwalk As New SqlCommand

    Public Sub New()
        Dim u As New proj.UClass
        m_conCustom = New SqlConnection(u.GetConncectionString()) <-- Here's where it ERR
        m_conCustom.Open()
    End Sub
End Class

Here's UClass

    Public Function GetConncectionString() As String
        Return (ConfigurationManager.AppSettings("SQLConnection"))
    End Function

Any ideas?

TIA!

There's another line in MClass that calls GetConncectionString and it works.

Private m_mcw As MClass
    Public Sub New()
        Dim u As New proj.UClass
        Try
            m_strConnectionString = u.GetConncectionString()
            m_mcw = New MClass()
        Catch ex As Exception
            Dim exOut As New Exception(blah ... blah, ex)
            Throw exOut
        End Try
    End Sub
