I am  learning ArcGIS Server JavaScript API, trying to develop a samll application, I need to consume a WCF service ( I have a feature class with related table, one-to-many, I need to view and  edit the related table by selecting features on the map). I could find many samples  to consuming WCF with JQuery, but not dojo, in my company, the other teams are using JQuery except me, because I am using ESRI technologies. I wonder if there are some sample codes: ArcGIS server Javascript API with  Dojo and WCF services.  if somebody knows, please kindly let me know. Thanks. ... View more

In ArcGIS Server 10.1, when I use a secured service, in .xaml file, I do the following like: <esri:ArcGISDynamicMapServiceLayer ID="TestLayer", Url="http://mydomain/arcgis/rest/services/TestSv/MapServer" Token="XXXmnbgh-456xxxxxxx" /> It works fine. But recently I set up  ArcGIS Server system with Reverse Proxy server, set the Urls as https. When I use the following: <esri:ArcGISDynamicMapServiceLayer ID="TestLayer", Url="https://proxydomain/arcgis/rest/services/TestSv/MapServer" Token="XXXmnbvhk-476xxxxxxx" /> Even the token is valid, but it doesn't work. I tried SignInDialog sample with https, it didn't work either ( I already applied SP1 and security patch). http://resources.arcgis.com/en/help/silverlight-api/samples/start.htm#SignInDialogSimple any help ? Thanks. ... View more

Hi, I have an enterprise SQL Server ArcSDE geodatabase, I  have many window group users. From ArcCatolog,  I grant privileges to the goups users, all of them fine  are except 2 groups. I got error : Invalid Parameter value passed to function. I could not figure out why, but  these two groups have the longest user name, including the domain name, total are 33 character.

I have a ArcSDE 10.0 geodatabase with SQL Server 2008 enterprise, the database is about 160 gb, one datafile(.mdf). Last Friday, I just upgraded to 10.1. Everything thing is fine with the database except deleting feature dataset or feature class. Deleting is really slow, it takes 2-15 minutes from ArcCatolog, even the feature dataset is small. The problem ( 10.1) is the same as in 10.0. Any suggestion about how to improve the issus will be appreciated. ... View more
