  4. Copy the following code into the code module.

    Public Sub ZoomToDomainExtent()
    Dim pMxDoc As IMxDocument
    Dim pMap As IMap
    Dim pActiveView As IActiveView
    Dim pContentsView As IContentsView

    Set pMxDoc = Application.Document
    Set pMap = pMxDoc.FocusMap
    Set pActiveView = pMap
    Set pContentsView = pMxDoc.CurrentContentsView

    Dim pLayer As ILayer
    Dim pDataSet As IDataset
    Dim pFeatureLayer As IFeatureLayer
    Dim pGeoDataset As IGeoDataset

    If Not TypeOf pContentsView.SelectedItem Is ILayer Then Exit Sub
    Set pLayer = pContentsView.SelectedItem
    Set pFeatureLayer = pLayer
    Set pGeoDataset = pFeatureLayer

    Dim pSpatialReference As ISpatialReference
    Dim pEnvelope As IEnvelope
    Set pSpatialReference = pGeoDataset.SpatialReference
    Set pEnvelope = New Envelope

    Dim dXmax As Double
    Dim dYmax As Double
    Dim dXmin As Double
    Dim dYmin As Double

    pSpatialReference.GetDomain dXmin, dXmax, dYmin, dYmax
    pEnvelope.XMax = dXmax
    pEnvelope.YMax = dYmax
    pEnvelope.XMin = dXmin
    pEnvelope.YMin = dYmin

    pActiveView.Extent = pEnvelope

    End Sub

  5. Close the Visual Basic Editor.
  6. Select Tools > Customize.
  7. Switch to the Commands tab.
  8. Select Macros from the Categories list.
