Shea, Short answer is no. I just had to put up with ArcMap failing after X iterations (can't remember how many but only a few thousands). Duncan

All (especially ESRI), I'm at a cross road with upgrading to 10.1 but some of my clients are locked into 9.x or 10.0. With the release of 10.0 ESRI offered the AddIN, this is great and makes life a lot easier. But I have concerns about compatibility. Can an AddIN built in 10.1 be installed and run in 10.0 assuming it does not use functionality specific to 10.1? I came across this thread here but no-one seems to have had any success. So whats the official line on this? 10.1 AddIns are not compatible with 10.0? I hope not!

I'm personally not too bothered about viewing tables in the draw order I'm happy to jump in/out of draw order/source view. A tweak that would be very helpful is to be able to move the tables just like when you drag a layer to a new position. If I have a dataframe that has many standalone tables in it then is becomes a pain to scroll to a table, why can't I just drag it to the top and work with it?

Don't know what the problem is but as you are using vba why not put in a "doevents" call?

Ken, Excellent! I've tried it out on my v10 setup (so not 10.1 yet) but very impressed. Very pleased that it filters it and it works fast! Duncan

All/ESRI, I've finally been able to have a sneak view of 10.1 and as a developer whose career was built on VBA I was interested in finding out if ESRI really had blitzed VBA. To my great joy and happiness I found VBA could still be installed. Deliberately hidden and various hoops needed jumping through but one could eventually get back VBA, hooray my career is not over yet! Now... I know you [ESRI] keep saying everything should be .Net and Python now and all my current projects are, so I'm doing what you are demanding of us, but I have always found the VBA help file superior for search for ArcObjects. I've never liked the integration of Help into Visual Studio it's just slow and clunky. Your API online pages are slow, I spend half my time watching a gray circle and the web page load up. But the VBA help file (the chm file) is fast, responsive and you can search by index (as you type, it filters the list). This help file has been the bedrock of my development projects and now it's gone... 😞 It looks like you been expanding ArcPy and you document that in the desktop help, why can't we have an ArcObjects API help document that's not embedded into Visual Studio if VBA has to go? If there is a way of getting the ArcObjects API as a chm file which can be used offline and is fast, that must surely be a good thing? Duncan

Akhil, The code below will set a layers symbology to Triangle 1 marker. Duncan Public Sub Symbolize() ' Get Layer Dim pMXDoc As IMxDocument Set pMXDoc = ThisDocument Dim pMap As IMap Set pMap = pMXDoc.FocusMap Dim pLayer As ILayer Set pLayer = pMap.Layer(0) Dim pGeoFeatureLayer As IGeoFeatureLayer Set pGeoFeatureLayer = pLayer ' Create a Font Dim pFontDisp As IFontDisp Set pFontDisp = New stdole.StdFont pFontDisp.Bold = True pFontDisp.Name = "ESRI Default Marker" ' Create a character Dim pCharacterMarkerSymbol As ICharacterMarkerSymbol Set pCharacterMarkerSymbol = New CharacterMarkerSymbol With pCharacterMarkerSymbol .size = 8 .Angle = 0 .Font = pFontDisp .CharacterIndex = 35 ' This is Triangle 1 End With ' Update renderer, this assumes the renderer is a single feature Dim pSimpleRenderer As ISimpleRenderer Set pSimpleRenderer = pGeoFeatureLayer.Renderer Set pSimpleRenderer.Symbol = pCharacterMarkerSymbol Set pGeoFeatureLayer.Renderer = pSimpleRenderer ' Refresh document pMXDoc.UpdateContents pMXDoc.ActiveView.Refresh End Sub

Stan, It's the IRasterWorkspaceEx Interface you need to be using, search help on this and you will find an example. Duncan

Eric, Just a thought, if you have used the geoprocessing clip tool could you not then use the SetNull tool after the clip, if the ISaveAs is not working? Duncan

Sui, You could also try and use the IUnitConverter Interface. Although not sure if the conversion would be accurate if your source coordinate system is in decimal degrees. I think some ArcObjects expect your geometries to be projected for them to work best? Duncan

I agree with Florian, if you look at the ICalculator interface it does not say that the expression should be Python or even VB, so what is it ESRI?

Joel, Did not know about this tool but it's worth mentioning that it is only available for people with ArcEditor or greater. Duncan

Roger, I've used the technique you are using to stop/start a script based upon a boolean output from a calculate value tool but I've not implemented branching with it, not even sure if you can? Anyway you need to write a branching script and expose it as a tool to be able to do this. It's documented here for 9.3 and here for version 10. You'll be able to view their Python code. Duncan

Michael, I think the problem is here: topoOp = intersectingGeometry geo = topoOp.Intersect(intersectingGeometry, esriGeometryDimension.esriGeometry0Dimension) You set topoOP to point to intersectingGeometry then you intersect it with the same geometry intersectingGeometry Duncan

This is a great idea, I find that symbolizing a layer with an arrow decoration can really slow down the display if reviewing the dataset at full extent. so to be able to quickly flash up an arrow direction would be very helpful indeed.
