Just came across this. We have a development sever within our organization (let's call it DMC) that is used for development web maps. I've mostly used v2.8 of the API but recently upgraded one app to v3.3 Yesterday I started developing a completely new app using one of the ESRI v3.4 samples as a starting point. I finally got around to adding in the basemap selection dropdown button as shown in this ESRI sample. I've modified it slightly but my modified version has run fine under v2.8 and v3.3: var map, initExtent, basemapGallery;                 basemapGallery = new esri.dijit.BasemapGallery({    showArcGISBasemaps: true,    map: map });   //Manually add the USGS Topo basemap into the basemap gallery var usgsLayer = new esri.dijit.BasemapLayer({    url: "http://server.arcgisonline.com/ArcGIS/rest/services/USA_Topo_Maps/MapServer" }); var usgsBasemap = new esri.dijit.Basemap({   layers: [usgsLayer],   title: 'USGS Topoography' }); basemapGallery.add(usgsBasemap); // Populate the basemap gallery widget with the list of ESRI basemaps dojo.connect(basemapGallery, 'onLoad', function () {   //add the basemaps to the menu but exclude the "Oceans" basemap   dojo.forEach(basemapGallery.basemaps, function (basemap) {   if (basemap.title != 'Oceans') {    dijit.byId("basemapMenu").addChild(new dijit.MenuItem({      label: basemap.title,      onClick: dojo.hitch(this, function () {this.basemapGallery.select(basemap.id);})    }));   }   }); }); When I just added this code into my v3.4 based app, it would throw an error during the "new esri.dijit.BasemapGallery" line of code. Under IE, it would just say "Access Denied" but Firefox returned: "Error: Permission denied for <file://> to create wrapper for object of class UnnamedClass http://serverapi.arcgisonline.com/jsapi/arcgis/3.4/ Line 15" I spent some time verifying that my code hadn't copy/pasted wrong and then zero'd in on the reference to "file" in the Firefox error. In the address bar of my browser, the path to the HTML was a UNC format path ala "\\dmc\appName\index.html" but the minute I changed the URL to "http:\\dmc\appName\" the basemapGallery no longer threw an error. and loaded successfully. Very strange. This did not throw an error in previous versions of the API. Steve ... View more

I just started playing with routeTask and, although it works great, it can produce some unintended routes. I can't see an obvious way to do this so I'll just ask- can you specify a parameter to the route task so that any route that is calculated MUST utilize a specific street? I'm considering using the routeTask to help map road segments by specifying the starting and ending locations. The problem occurs if there's a major road that parallels the actual road I want because the calculated route will jump onto the major road instead of following the local road. In my simple tests, the route task would create the route I wanted if I was able to add another stop along the road I'm interested in and between the two end points. Thanks! Steve ... View more

I'm just getting my feet wet with the PrintTask functionality in v3.3 of the API. Ideally, I just wanted to take what I see on the screen, export it to a JPEG, and then insert that into a "report" that I build on the fly with JS & HTML. I'm using PrintTask and the "Export Web Map Task" from our 10.1 install of ArcGIS Server. The first attachment (screenshot01) is what I see on my screen. The second attachment (screenshot02) shows the exported JPEG as it appears in my generated report. As you can see, they only loosely resemble each other. I have two census feature layers that have dynamic labels which do not even show up in the exported JPEG (this might be a bug? I recall reading a thread recently somewhat related to this..). Next, the linework in the exported image are huge and bloated compared with what I see on screen. How do I produce an exported image that is as close to WYSIWYG as possible? Here's my relevant code for my printTask creation: pTemplate = new esri.tasks.PrintTemplate(); pTemplate.exportOptions = {   width: 600,   height: 400,   dpi: 300 }; pTemplate.format = "jpg"; pTemplate.layout = "MAP_ONLY"; pTemplate.preserveScale = false; pTemplate.showAttribution = false; var params = new esri.tasks.PrintParameters(); params.map = map; params.template = pTemplate;   thePrintTask = new esri.tasks.PrintTask(url); thePrintTask.execute(params, function(result) {   jpgMapDiv = theDocument.createElement("div");   jpgMapDiv.setAttribute("id","jpegMap");   setStyle(jpgMapDiv, {    width : '95%',    height: '400px',    marginRight : 'auto',    marginLeft : 'auto',    borderTop: '2px solid black',    padding: "10px"   });         jpgMapDiv.innerHTML = "<img src=\"" + result.url + "\" style=\"border:2px solid black;left:25%\"\>";   theDocument.body.appendChild(jpgMapDiv); }); THANKS!
