Hi there,
I'm trying to create a new ArcMap instance (ie. open a map in a separate ArcMap window) once a user clicks a button on an addin form.

I can get the map to open - but it's in the same ArcMap window (see code below).
        Dim mApp As ESRI.ArcGIS.Framework.IApplication
        Dim mDoc As ESRI.ArcGIS.Framework.IDocument
        mDoc = My.ArcMap.Application.Document
        mApp = mDoc.Parent
        mApp.Visible = True
        mApp.NewDocument(False, <file>)

How do I get the map to open in a new ArcMap window? I'm using ArcMap 10 and Visual Basic Express .NET 2008 SP1.
