The Projection object contains all the methods and properties of projections.
In order to convert a map document's projection, it is necessary to make a copy of the current map document projection with the CopyDocProjection method. Make the desired changes to the copy of the projection, apply the new changes with the ConvertProjection method, and then delete the copy of the projection. NOTE: It is important to delete the copy of the projection created with CopyDocProjection when you are done with it. If the projection copy is not deleted, the MapViewer application process will run even after MapViewer and Scripter are closed.

Example
This example creates a hatch map and copies the projection.
Sub main
'Creates an instance of the MapViewer Application
'object and assigns it to the variable named "mvApp"
Set mvApp = CreateObject("MapViewer.Application")
'Makes the application main window visible
mvApp.Visible = True
'Assigns the location of the samples folder to
'the variable "InPath"
InPath$ = mvApp.ApplicationFolder + " samples\"
'Creates a map document object, and assigns it
'to the variable named "Plot"
Set Plot = mvApp.Documents.Add(DocType:=mvDocPlot)
'Creates a hatch map object and assigns it to the
'variable named "HatchMap"
Set HatchMap = Plot.CreateHatchMap( BoundaryFileName:=InPath$ + _
"co2010.gsb", DataFileName:=InPath$ + "co2010.dat", PIDCol:=1, _
VarCol:=5, NumClasses:=4)
'Creates a copy of the map's projection and assigns
'it to the variable named "Proj"
Set Proj = Plot.CopyDocProjection
End sub
