Question

A userform in Excel VBA started hitting the memory limit of 64 kB today. I expect this interface to grow by 10-15% at least and can easily see it growing larger now. VB6 sounded like it would be better, but I read it also has a 64 kB memory limit of the same kind.

I am stuck using Visual Basic since other workers on this project do not know C++ or any other language. Any quick suggestions besides condensing the form controls?

I’ve just written the following simple test…

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    Try
        While True
            Dim B As New Button
            Me.Controls.Add(B)
            Me.Text = String.Format("Controls: {0}", Me.Controls.Count)
        End While
    Catch ex As Exception
        Me.Text = ex.Message
    End Try
End Sub

It started having issues ~4,000 controls. I suspect this is due to the memory limitations on the laptop I’m on.
