SharePoint 2010 : Sandbox Solution Part 4 Full Trust Proxy

Full Trust Proxy:  Sandboxed solution to execute an action that is ordinarily not available to sandboxed solutions.
One of these techniques is to create a special kind of operation that runs in a full trust process, but that can be called from a sandboxed solution. The operation is deployed as a farm solution by a farm administrator who trusts it and is prepared to let sandboxed solutions call it. These operations are calledfull-trust proxy operations. (Microsoft Definition).

Other words: Full trust proxy is a farm solution that runs Outside the Sandbox Solution. Sandbox Solution uses that assembly and call Execute method to perform the operation which was out the scope of sandbox solution. The class inherits from SPProxyOperation. Full trust Proxy Input parameters used as serialize class (used “Serializable” attribute) that inherits from SPProxyOperationArgs Register proxy with User Code Service during Feature activation. Referenced the assembly in Sandbox solution use it.Steps : Create…

SharePoint 2010 ECMA Scripts code snippets

ECMScript you need to create a client context before you can retrieve data from a SharePoint site.
With ECMAScript you can retrieve the client context from the SharePoint site in which the script runs. Use the Load method to specify which data to load from SharePoint.
Use the asynchronous method executeQueryAsync to retrieve the information from SharePoint. This method needs a reference to a callback method when the execution succeeds and a reference to a callback method when the execution fails.
To Set and Get the Properties there are ways to get the information. get_methodnameset_Methodname example get_web(), set_title etc

Update, Insert, Delete Code snippets

1. Load Site Data  

<script type="text/javascript">
var clientContext = null;
var web = null;
ExecuteOrDelayUntilScriptLoaded(Initialize, "sp.js");
function Initialize()
clientContext = new SP.ClientContext.get_current();
web = clientContext.get_web();
clientContext.load(web, 'Title')…

Sandbox Solution you get the restricted subset permission of SharePoint Object Model.  SPUCHostService.exe :  Code runs under special monitored process called  SPUCHostService.exeSPUserCodeWebPart : Web Part that loads the Sandbox Web part Called SPUserCodeWebPart Wrapper.SPUCWorkerProcess.exe : Sandbox run under the worker Process called SPUCWorkerProcess.exe.  This is process you need to Attach for debugging.SPUCWorkerProcessProxy.exe : Communication to the farm under full trust using SPUCWorkerProcessProxy.exe
We need Sandbox solution because: You don’t have a SharePoint Farm Permission but you still want to deploy the custom code in SharePoint this is only way to deploy the custom code in SharePoint.Hosted environment you want to deploy the custom code. Then only way to use sandbox solution to deplo…
