Dim LayoutDict As DBDictionary = Tr.GetObject(Db.LayoutDictionaryId,
OpenMode.ForRead)
For Each id As DictionaryEntry In LayoutDict
Dim MyLayout As Layout = DirectCast(Tr.GetObject(DirectCast(id.Value,
ObjectId), OpenMode.ForRead), Layout)

You can try this, it uses AutoCAD interop so make sure you reference those assemblies. I replaced/removed lines from your code, you can see the differences here:
{code}
Dim Db As Database = MyDocument.Database
Dim Tr As Transaction = Db.TransactionManager.StartTransaction
Dim MyLayoutManager As Autodesk.AutoCAD.DatabaseServices.LayoutManager = LayoutManager.Current()
Dim acadApp As AcadApplication = Autodesk.AutoCAD.ApplicationServices.Application.AcadApplication

Try
Dim LayoutDict As DBDictionary = Tr.GetObject(Db.LayoutDictionaryId, OpenMode.ForRead)
For Each id As DictionaryEntry In LayoutDict
Dim MyLayout As Layout = CType(Tr.GetObject(id.Value, OpenMode.ForRead), Layout)
MyLayoutManager.CurrentLayout = MyLayout.LayoutName
acadApp.ZoomExtents()
Next
Finally
Tr.Commit()
End Try
{code}

It might help to see the rest of your code, specifically where the sub is being called.
I get an error and crash when calling your MyZoom sub in a command sub defined with the "CommandFlags.Session" flag:
{code}
<CommandMethod("LAYOUTZM", CommandFlags.Session)> _
Public Sub LAYOUTZM()
MyZoom(AcApp.DocumentManager.MdiActiveDocument)
End Sub
{code}
