Object accessed from another Class

In vb.net i create two classes. In First class i define a property to return a single value and in second class define one function it get values from property and return a single value. I call the function when i click the button.

I create a object for property and use this object to call the property when i press enter in form after entering the number in text box. Values can be insert properly using first class(property) and it return safely. But in second class i create a object for Property and access the variable from first class (that is property defined class). It store only zero here, so it return zero value.

But if i give shared as variable in first class, this value can access in function through classname.varia blename, because of shared.

I need to access the variable through object. My code is below. Let me know any wrong in this code

Code:

Public Class clsProperty

    Public m_Value As Integer

    Public Property InsertValues() As Integer
        Get
            Return m_Value
        End Get
        Set(ByVal value As Integer)
            m_Value = value
        End Set
    End Property
End Class

 Public Class clsFunctions
    Public Function DisplayValue() As Integer
        Try
            Dim objProp As New clsProperty
            Dim returnValue As Integer
            returnValue = objProp.m_Value
            Return returnValue

        Catch ex As Exception
            Throw ex
        End Try
    End Function
End Class

Private Sub btnTest_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnTest.Click
        Try

            Dim objProperty As New clsProperty
            Dim objFunction As New clsFunctions
            objProperty.InsertValues = Val(txtInput.Text)
            txtOutput.Text = objFunction.DisplayValue()
        Catch ex As Exception
            MessageBox.Show(ex.Message)
        End Try

End Sub

I didn't see any line of code that insert value into Property object in your Function object here. You created two objects, one is Property and one is Function. In Function object there is a Property object, this object is obviously has no relationship with the first Property object. Then what is your point when you saying that you can not retrieve value from shared object?
cheers.
