I'm stuck on how to collapse all layers in my ArcMap projects (9.3). I've tried a few bits of sample code, but they all seem to fail for some reason or other.
Some of the layers might be grouped, and some are imagery or WMS layers if that makes a difference.
Here is some code I have tinkered with, but does not work:
Dim pMxdoc As IMxDocument Set pMxdoc = ThisDocument Dim pFeatLayer As IFeatureLayer Dim pEditLayers As IEditLayers Set pEditLayers = pEditor Dim pMap As IMap Set pMap = pMxdoc.FocusMap Dim pLayer As ILayer 'Collapse any expanded grouplayers Dim pGroupLayer As IGroupLayer For i = 0 To pMxdoc.FocusMap.LayerCount - 1 Set pLayer = pMxdoc.FocusMap.Layer(i) 'Check if the reached layer is a group If TypeOf pLayer Is IGroupLayer Then Set pGroupLayer = pLayer if pGroupLayer.Expanded = true Then pGroupLayer.Expanded = false End if End If Next i pMxdoc.UpdateContents pMxdoc.ActiveView.Refresh
