This article explains how to use UIPAB pattern when working with MDI in VB.NET

Introduction

When I started designing my project UI (Win Forms) based on UIPAB pattern, I've come across few issues. One of them is implementing UIPAB in MDI. In fact I searched (u can guess it) for it, many people asking the same question but unfortunately no replies for them (to me too), so I solved it in my own way.<o:p>

<o:p>

Before going to solution I want to thank all programmers who wrote UIPAB articles and helped me a lot in understanding this (of course our PC is also one of them).<o:p>

<o:p>

Solution

Yea, it’s very simple.<o:p>

I’ve a class called CommonClass (you can have your own name…).<o:p>

<o:p>

Public Class CommonClass<o:p>

Public Shared mdi As New MDIFORM<o:p>

End Class<o:p>

<o:p>

Here MDIFORM is the name of the MDI Form.<o:p>

Now all you have to do is use this shared object in your Starter class.<o:p>

<o:p>

<STAThread()> _<o:p>

Public Shared Sub <st1:place w:st="on">Main()<o:p>

AddHandler Application.ThreadException, AddressOf Application_ThreadException<o:p>

Application.Run(CommonClass.mdi)<o:p>

End Sub<o:p>

<o:p>

One more step, last one…<o:p>

Put below two lines of code in each of your Child Form Load event, that’s it <o:p>

<o:p>

Me.MdiParent = CommonClass.mdi<o:p>

Me.Dock = DockStyle.Fill<o:p>

<o:p>

Now you know how simple is it, right??<o:p>

<o:p>

Here I put complete UIPAB demo project, in which 5 child forms and 1 MDI form are there.<o:p>

<o:p>

Please feel free to send me your feedback/suggestions.<o:p>
