Also, do you know how to read A XML file, i am having difficulty in doing that. I am using following for this: Dim xmlStream As esriSystem.IXMLStream Dim xmlReader As esriSystem.IXMLReader Set xmlStream = New esriSystem.xmlStream xmlStream.LoadFromFile "D:\Directions.xml" Set xmlReader = New esriSystem.xmlReader xmlReader.ReadFrom xmlStream I don't know what to do after this. However, I tried several methods of IXMLReader but couldn't get anything working. Thanks, Nagendra

Hi Jay, My goal is to count number of left and right turns in a route and turns should be made at an intersections. If nothing works out, I was thinking to read the XML file to get count of "left" and "right" words. Btw, how does ArcGIS decide left and right turns? Thanks, Nagendra

Hi Jay, Then is there any way to get these turns through street direction? I can export the directions as a XML output but how can I get left and right turns from that? If i try to calculate angles between edges than it will increase the computing time. So, I am thinking if there is something in the results that can be used for this. Thanks, Nagendra

Hi Jay, Thank you for the reply. I used the same VBA code for turns but output had nothing. Btw, if street directions are available doesn't it mean that turns are there too? if not then do we have to import turns separately? Thanks, Nagendra

Hi, I am also trying to find no. of turns (left and right) along a route. But I have ArcGIS 9.3, and I guess, this add-in is for ArcGIS 10 as it doesn't recognize 9.3. So, it would be helpful for me if any one can please post the VBA code associated with the add-in? Also, I know that turns can be accessed via traversal but when I use that with my network data set it gives me a blank shapefile, however, junctions and edges outputs are perfectly fine. That left me wondering if it has anything to do with the way I set up my turns while creating the network dataset. That time, I checked "Yes" to the question "Do you want to model turns in this network?" with "Global turns" checked as the turn sources. Also, at the end, I established driving directions by just providing "Street Name Fields". Alternatively, I tried using INAStreetDirectionsAgent, but it gives me the directions in XML output. I couldn't find any other useful output from that. Even, with the XML output I don't know how to use it to get the number of turns. Any help is appreciated. Thanks, Nagendra

Hi, I have a loop that adds two layers in every step, and both layers are from different folders. That means that the loop involves going through two different folders simultaneously. I know how to loop through one folder but don't know how to do it for multiple folders. Following is what I want to do: inputfile1 = Dir(folder1 + "*.shp") inputfile2 = Dir(folder2+"*.shp") do while inputfile1 <> "" ' Add inputfile1 and inputfile2 to map ' go to next files in respective folders inputfile1=Dir inputfile2=Dir Loop Thanks, Nagendra

Thanks, Sandhu. Are line barriers possible in ArcGIS 9.3? or it's new in ArcGIS 10? Thanks, Nagendra

Hi, I want to create a network dataset from a shapefile. It could be done if VBA code is written in ArcCatalog. But I am wondering if there is a way to do it from VBA code in ArcMap. Is it possible to control ArcCatalog operations from ArcMap? I have a loop where every step has to create a network dataset. Thanks, Nagendra

Hi, For every iteration, I update my cost field and subsequently build the network dataset to reflect those changes. Following is the code I am using for building the network dataset. Private Sub buildNetworkDataset() Dim pWorkspaceFactoryM As IWorkspaceFactory Dim pFeatureWorkspaceM As IFeatureWorkspace Set pWorkspaceFactoryM = New ShapefileWorkspaceFactory Set pFeatureWorkspaceM = pWorkspaceFactoryM.OpenFromFile("C:\data\", 0) Dim pWSExtMgr As IWorkspaceExtensionManager Dim pUID As New UID Dim pWSExt As IWorkspaceExtension Dim pDSCont As IDatasetContainer2 Dim pND As INetworkDataset Dim pGeoDS As IGeoDataset Dim pNB As INetworkBuild Dim pReturnedExtent As IEnvelope Set pWSExtMgr = pFeatureWorkspaceM pUID.Value = "{4C1B151C-48C3-46C5-AB57-E6B941A1D00A}" Set pWSExt = pWSExtMgr.FindExtension(pUID) Set pDSCont = pWSExt Set pND = pDSCont.DatasetByName(esriDTNetworkDataset, "Network_ND") Set pGeoDS = pND Set pNB = pND Set pReturnedExtent = pNB.BuildNetwork(pGeoDS.Extent.Envelope) End Sub But it encounters a run-time error '-2147220937 (80040237)': Automation Error at the very last line: Set pReturnedExtent = pNB.BuildNetwork(pGeoDS.Extent.Envelope) Now, I can't figure out what is wrong with the code. Can anybody help me on this? Thanks, Nagendra

Hi, I have created a network data set (ND) specifying the impedance. But I want to change the impedance value of few features every time I run the route solver. But it looks like once you have created the ND, no matter what are the new impedance values in the attribute table, route will be solved based on the original impedance values present while creating the ND. Is there a work around to use impedance values dynamically? Thanks, Nagendra

Hi, As ESRI provides a DVD of USA street map (comes in ESRI Data & Maps Media Kit), I was wondering about the road attributes available with the map. Does it have only name and length of the street or there are other attributes too? I apologize if my post is in a wrong section. Thanks

Thanks a lot. So it sounds like you can solve the route but need to analyze the results more. One way can be to spatially select all the roads that overlap your route and then summarize them and the other can be to add the "traversal" results being stored in memory as a feature class to ArcMap and summarize them. The traversal results has every edge of the route with its network attributes. You can use the following link to see how to access the traversal result: http://help.arcgis.com/en/sdk/10.0/arcobjects_net/conceptualhelp/index.html#//000100000245000000 Jay Sandhu

Hello, I am new to network analyst, so having some trouble working with it. I have some GPS points and want to construct the corresponding route. So, I started with exporting my GPS points to ArcMap and then used 'new route', and 'add locations' sequentially to snap my GPS points to the network. Till this point, everything seems alright but after this I don't know how to proceed. I also solved my route and got the route consisting all GPS points. This route gives me total length and doesn't get any attributes from the network. In my network I have few attributes, such as no. of lanes, functional class etc. and for my new route I want to find some coverage statistics such as, % of 2 lanes, 3 lanes.., % of functional class = 1, 2, 3 etc. Is there a way to get attributes from the network so that I can calculate some of these statistics for my route? Thanks
