Run Single Instance of .NET Compact Framework Application

A .NET compact framework application I work on, in some cases, seemed to have multiple instances of itself running at a time. Although the framework handles multiple instances from being loaded, it can't handle it if the call to load is in very quick succession of each other.

I hunted around a came across this useful (and novely narrated) video article on MSDN.

The only addition I would make to this, is that VB.NET does allow the use of the Using statement in more recent versions of the framework.

Add a Border to a Panel Using .NET Compact Framework

After spending quite some time working out how to add a border round a panel control in the .NET compact framework, I finally got it working. It's pretty easy to be honest.

VB.NET

Using g As Graphics = e.Graphics
    Using p As New Pen(Color.Black, 1)
        g.DrawRectangle(p, 0, 0, MyPanel.Width - 1, MyPanel.Height)
    End Using
End Using

C#

Using (Graphics g = e.Graphics) {
    Using (Pen p = New Pen(Color.Black, 1)) {
        g.DrawRectangle(p, 0, 0, MyPanel.Width - 1, MyPanel.Height);
    }
}

You need to make sure that this code is put in the Paint event of your panel.
