Creating WebPart Page in feature activated event, sandbox solution

Question

Hi All.

Im going to create new webpart page programmatically in feature activated event as sandbox solution. I have already created full trust proxy and some additional classes and methods. I've successfully deployed features(and they activated) and didnt get any errors, but no page was created as well. My code is next

1) This classes is included in FullTrustFeature wich is activated as farm solution.

namespace FullTrustProxy
{
    [Serializable]
    public class FulltrustProxyServiceArgs : SPProxyOperationArgs
    {
        public static string StaticProxyOperationTypeName
        {
            get
            {
                return "FullTrustProxy.FullTrustProxyService";
            }
        }

        public static string StaticProxyAssemblyName
        {
            get
            {
                return "FullTrustProxy, Version=1.0.0.0, Culture=neutral, PublicKeyToken=2dfe43bced7458f6";
            }
        }

        public string ProxyOperationTypeName
        {
            get
            {
                return "FullTrustProxy.FullTrustProxyService";
            }
        }

        public string ProxyAssemblyName
        {
            get
            {
                return "FullTrustProxy, Version=1.0.0.0, Culture=neutral, PublicKeyToken=2dfe43bced7458f6";
            }
        }

        public SPFeatureReceiverProperties Properties
        {
            get;
            set;
        }

        /// <summary>
        /// Create Web Part Page
        /// </summary>
        /// <param name="web">SPWeb object</param>
        /// <param name="fileName">File name to create</param>
        public void CreateWebPartPage(SPWeb web, string fileName, string featureName)
        {
            string templateFilename = "spstd1.aspx";
            string hive = SPUtility.GetGenericSetupPath("TEMPLATE\\" + SPContext.Current.Web.Language + "\\STS\\DOCTEMP\\SMARTPGS\\");

            using (FileStream stream = new FileStream(hive + templateFilename, FileMode.Open))
            {
                SPFolder libraryFolder = web.GetFolder("Site Pages");                
                    SPFileCollection files = libraryFolder.Files;
                    SPFile newFile = files.Add(fileName, stream);
                   
                    newFile.CheckIn(string.Format("File added by '{0}' feature", featureName), SPCheckinType.MajorCheckIn);
                    newFile.Publish(string.Format("File published by '{0}' feature", featureName));
                    newFile.Approve(string.Format("File published by '{0}' feature", featureName));                
            }
        }
    }

    public static class Extensions
    {
        /// <summary>
        /// Gets the web.
        /// </summary>
        /// <param name="properties">The properties.</param>
        /// <returns></returns>

        public static SPWeb GetWeb(this SPFeatureReceiverProperties properties)
        {
            SPWeb site;
            if (properties.Feature.Parent is SPWeb)
            {
                site = (SPWeb)properties.Feature.Parent;
            }
            else if (properties.Feature.Parent is SPSite)
            {
                site = ((SPSite)properties.Feature.Parent).RootWeb;
            }
            else
            {
                throw new Exception("Unable to retrieve SPWeb - this feature is not Site or Web-scoped.");
            }
            return site;
        }

    }

    public class FullTrustProxyService : SPProxyOperation
    {
        // Uncomment the method below to handle the event raised after a feature has been activated.
        #region Public constant members

        /// <summary>
        /// define the name of file
        /// </summary>
        public const string PermissionManagementPage = "CustomWebPartPage1.aspx";
        public const string PermissionManagementWebPartFileName = "CustomWebPart.webpart";
        #endregion

        public override object Execute(SPProxyOperationArgs args)
        {
            var arguments = (FulltrustProxyServiceArgs)args;
            string featureName = "KinderGartenDefaultPageFeature";
            SPWeb web = arguments.Properties.GetWeb();

            try
            {
                arguments.CreateWebPartPage(web, PermissionManagementPage, featureName);
            }
            catch (Exception ex)
            {
                return ex.Message;
            }
            return "Success";
        }
    }
}

2) Event receiver in Farm Solution wich will register Full trust proxy assembly

[Guid("550fdc91-38bd-4272-a6b7-8bdfef719476")]
    public class FullTrustProxyFeatureEventReceiver : SPFeatureReceiver
    {
        // Uncomment the method below to handle the event raised after a feature has been activated.

        public override void FeatureActivated(SPFeatureReceiverProperties properties)
        {
            SPUserCodeService userCodeService = SPUserCodeService.Local;
            var simpleOperation = new SPProxyOperationType(
                            FulltrustProxyServiceArgs.StaticProxyAssemblyName,
                            FulltrustProxyServiceArgs.StaticProxyOperationTypeName);
            userCodeService.ProxyOperationTypes.Add(simpleOperation);
            userCodeService.Update();

        }
}

3) EventReceiver of sanbox solution  which call proxy service and execute operation

 [Guid("6f0d5b5e-8b22-43df-9143-1fad29e9704c")]
    public class DefaultPageFeatureEventReceiver : SPFeatureReceiver
    {
        public override void FeatureActivated(SPFeatureReceiverProperties properties)
        {
            var proxyArgs = new FulltrustProxyServiceArgs();
            proxyArgs.Properties = properties;
            var proxy = new FullTrustProxyService();
            proxy.Execute(proxyArgs);
            // I've tried the code bellow but feature wasn't activated while deploing 
	    //var result = SPUtility.ExecuteRegisteredProxyOperation(
            //                            proxyArgs.ProxyAssemblyName,
            //                            proxyArgs.ProxyOperationTypeName,
            //                            proxyArgs);

        }

Am I doing something wrong? Please advice me something dont know what to do else

 

Answer 1

Some additional info. If I use 

 var result = SPUtility.ExecuteRegisteredProxyOperation(
                            proxyArgs.ProxyAssemblyName,
                            proxyArgs.ProxyOperationTypeName,
                            proxyArgs);

to call proxy I get an error 

Exception: Microsoft.SharePoint.UserCode.SPUserCodeSolutionExecutionFailedException: Unhandled exception was thrown by the sandboxed code wrapper's Execute method in the partial trust app domain: An unexpected error has occurred. ---> Microsoft.SharePoint.UserCode.SPUserCodeSolutionProxiedException: Type 'Microsoft.SharePoint.SPFeatureReceiverProperties' in Assembly 'Microsoft.SharePoint, Version=14.900.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' is not marked as serializable.

What do I need to serialize?

Answer 2

Additional info

I commented some rows and previous error gone, but now when I use

var result = SPUtility.ExecuteRegisteredProxyOperation(
                            proxyArgs.ProxyAssemblyName,
                            proxyArgs.ProxyOperationTypeName,
                            proxyArgs);

to call execute method of full trust code. I get and error Microsoft.SharePoint.UserCode.SPUserCodeSolutionProxiedException: Could not load file or assembly 'FullTrustProxy, Version=1.0.0.0, Culture=neutral, PublicKeyToken=2dfe43bced7458f6' or one of its dependencies. The system cannot find the file specified.

I dont know why, everything looks fine. Any Ideas?

Answer 3

I still need a sollution, can't solve myself

Answer 4

In order to programmatically create a publishing page inside full-trust proxy of sandbox solution, you need spcontext to get to the right spsite and spweb etc. The spcontext is not available inside full-trust proxy operation class. Because sandbox proxies runs under spucworkerprocess.exe not the w3wp.exe.

http://msdn.microsoft.com/en-us/library/ff798433.aspx

You can pass a siteid to the proxy operation class and create spsite instance explicitly

Answer 5

Thanks a lot for reply.

Ectually it was not spcontext problem. I went to GAC folder and found out that there is my asssebly, but with different Public Token Key. So I changed it and now get another error Microsoft.SharePoint.UserCode.SPUserCodeSolutionProxiedException: Object reference not set to an instance of an object.   It can't run execute method on row

var result = SPUtility.ExecuteRegisteredProxyOperation(
                                            proxyArgs.ProxyAssemblyName,
                                            proxyArgs.ProxyOperationTypeName,
                                            proxyArgs);

I comment all code on SPProxyOperation Execute method, does enyone know what the reason of it?

maybe tha assembly is not registered, how can I check?

Answer 6

Ok. I checked if assembly is registered. It is. I write webpart wich shows me that

SPUserCodeService userCodeService = SPUserCodeService.Local;

            foreach (SPProxyOperationType item in userCodeService.ProxyOperationTypes)
            {
                Panel1.Controls.Add(new Label(){Text = "AssemblyName: " + item.AssemblyName + " TypeName: " + item.TypeName + " "});
            }

 

Some logs, maybe it helps

Answer 7

You can place breakpoint in the code-behind, attach the debugger to SPUCWorkerProcessProxy.exe and hit F5. This will help you to debug and figure out what's exactly going on
