This example checks the name of each member in the HTMLProjectItems collection for the loaded HTMLProject. If the name is Slide2, it then opens the generated HTML for that slide in the Microsoft Script Editor.
Dim i As Integer
With ActivePresentation.HTMLProject
For i = 1 To .HTMLProjectItems.Count
If .HTMLProjectItems(i).Name = "Slide2" Then
.HTMLProjectItems(i).Open
End If
Next
End With
