FAQ: Why is an Error Returned When SetCurrentLayer is Called after Installing ArcGIS 9.3 S

At ArcGIS 9.3 Service Pack 1, the SetCurrentLayer method found on the IEditLayers interface has been changed, so that it requires a valid layer and subtype value. An error will be raised if an invalid subtype code is passed. The exception to this change is when a shapefile is the current layer, a subtype value of 0 can be passed, because shapefiles do not support subtypes.

Use the following code to set the current layer when unsure of the default subtype.

Code:
Dim psubtypenum As ISubtypes
Dim subtype As Integer
If TypeOf pfeatClass Is ISubtypes Then
  Set psubtypenum = pfeatClass
  subtype = psubtypenum.DefaultSubtypeCode
Else
  subtype = 0
End If
pEditLayers.SetCurrentLayer pFeatLayer, subtype
