[RESOLVED] Object Disposed Exception - Multiple Forms

[Vb_Novice_User]

Hey Guys,

I am using VB 2008 Express Edition.

I have an app that has 2 forms (will be adding more). Button click on form1 opens form 2. The first time I run my app everything works fine, but when I click the close 'X' button on form 2 and try opening form 2 again by clicking the button on form 1, VB throws a Object Disposed Exception, Cannot access a disposed object

Here is my code on form 1

Public Class frmMain
    Dim myForm As Form3
    Private Sub btnWeld1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnWeld1.Click
        If IsDisposed Then Return
        If myForm Is Nothing Then
            myForm = New Form3
        End If

        myForm.Show()
    End Sub

End Class

Can you tell me how to fix this problem.

Thanks,
