            doc.Load(Server.MapPath("CrystalReport1.rpt"))
            doc.SetDataSource(Tbl)
            crypt.ReportSource = doc
            'Catch ex As Exception
            '  labelmsg.Text = ex.ToString()
            'FutureFeature()
        Catch NotImp As NotImplementedException
            Console.WriteLine(NotImp.Message)

    End Sub

What I have tried:

Public Sub loadlabe1()
Dim sql_Sel As String
Dim hIssId As Integer = 0
' hIssId = Request.QueryString("patID")
Try
Dim Tbl As DataTable
Dim doc As New ReportDocument()
Dim DM As New DataManager
sql_Sel = "exec MPI_Select @Reg_No=1 "
Tbl = DataManager.ExecuteScalarDS(sql_Sel, Me.SqlCon, "MPI_Select")
doc.Load(Server.MapPath("CrystalReport1.rpt"))
doc.SetDataSource(Tbl)
crypt.ReportSource = doc
'Catch ex As Exception
' labelmsg.Text = ex.ToString()
'FutureFeature()
Catch NotImp As NotImplementedException
Console.WriteLine(NotImp.Message)

End Try

End Sub

End Class

"NotImplementedException" is thrown when the control goes into a method that has been declared but has not been implemented completely. Please find below the sample code example from MSDN :-

VB.NET

Sub Main()
    Try
        FutureFeature()
    Catch NotImp As NotImplementedException
        Console.WriteLine(NotImp.Message)
    End Try


End Sub

Sub FutureFeature()
    ' not developed yet.
    Throw New NotImplementedException()
End Sub

In the above example FutureFeature method method has not been implemented completely and the statement "Throw New NotImplementedException" throws the exception which is being caught in the catch block of your code. Please debug the code line by line (with F11) to know the exact method throwing the exception. Please visit https://msdn.microsoft.com/en-us/library/system.notimplementedexception(v=vs.110).aspx
