  • Update a single field from a single entity with ria-services

    - by TimothyP
    There are situations where I only want to update a specific field of a single entity in the database. I loaded the entities of that type into my silverlight application, and I know they are constantly changing on the server... but there is one field which has to be set by the silverlight client... the server will only read it. How can I just send the new data for that field to the server? Example an Entity called "TextField". I have a list of TextFields loaded in the silverlight application and every now and then the user will update the Preload (string) property of an entity and that has to go back to the server without changing anything else on the server. I tried adding a simple SetPreloadText(...) method to the DomainService but that just makes Silverlight crash with some odd error code. Is there a way to this? Am I working against the idea of Silverlight here? I really don't want to send the entire object back because know that at any given time the version on the client will most likely be out of date. (which is ok for this specific application)

  • Gmail 3-legged OAuth access -- Zend_Mail_Protocol_Exception

    - by tchaymore
    I'm trying to access Gmail by using three-legged Oauth PHP code provided by Google ('google-mail-xoauth-tools') here: http://code.google.com/apis/gmail/oauth/code.html. I have my domain registered and everything seems to go fine with OAuth, but after I authorize access I get this error: Fatal error: Uncaught exception 'Zend_Mail_Protocol_Exception' with message 'cannot connect to host; error = Connection refused (errno = 111 )' in /home/tchaymor/public_html/gmail/Zend/Mail/Protocol/Imap.php:100 Stack trace: #0 /home/tchaymor/public_html/gmail/Zend/Mail/Protocol/Imap.php(61): Zend_Mail_Protocol_Imap->connect('imap.gmail.com', '993', true) #1 /home/tchaymor/public_html/gmail/three-legged.php(170): Zend_Mail_Protocol_Imap->__construct('imap.gmail.com', '993', true) #2 {main} thrown in /home/tchaymor/public_html/gmail/Zend/Mail/Protocol/Imap.php on line 100 This is my first time using OAuth with any Google products, so it could be something totally brainless I'm missing. Any suggestions would be most welcome (as suggestions for easier alternatives). I'm more on the designer rather than coder end, so the simpler the better.

  • Map a column to be IDENTITY in db with EF4 Code-Only

    - by Tomas Lycken
    Although I have marked my ID column with .Identity(), the generated database schema doesn't have IDENTITY set to true, which gives me problems when I'm adding records. If I manually edit the database schema (in SQL Management Studio) to have the Id column marked IDENTITY, everything works as I want it - I just can't make EF do that by itself. This is my complete mapping: public class EntryConfiguration : EntityConfiguration<Entry> { public EntryConfiguration() { Property(e => e.Id).IsIdentity(); Property(e => e.Amount); Property(e => e.Description).IsRequired(); Property(e => e.TransactionDate); Relationship(e => (ICollection<Tag>)e.Tags).FromProperty(t => t.Entries); } } As I'm using EF to build and re-build the database for integration testing, I really need this to be done automatically...

  • The specified type member 'EntityKey' is not supported in LINQ to Entities

    - by user300992
    I have 2 Entities "UserProfile" and "Agent", they are 1-many relationship. I want to do a query to get a list of Agents by giving the userProfileEntityKey. When I run it, I got this "The specified type member 'EntityKey' is not supported in LINQ to Entities" error. public IQueryable<Agent> GetAgentListByUserProfile(EntityKey userProfileEntityKey) { ObjectQuery<Agent> agentObjects = this.DataContext.AgentSet; IQueryable<Agent> resultQuery = (from p in agentObjects where p.UserProfile.EntityKey == userProfileEntityKey select p); return resultQuery; } So, what is the correct way to do this? Do I use p.UserProfile.UserId = UserId ? If that's the case, it's not conceptual anymore. Or should I write object query instead of LINQ query?

  • Using an existing IQueryable to create a new dynamic IQueryable

    - by dnoxs
    I have a query as follows: var query = from x in context.Employees where (x.Salary > 0 && x.DeptId == 5) || x.DeptId == 2 order by x.Surname select x; The above is the original query and returns let's say 1000 employee entities. I would now like to use the first query to deconstruct it and recreate a new query that would look like this: var query = from x in context.Employees where ((x.Salary > 0 && x.DeptId == 5) || x.DeptId == 2) && (x,i) i % 10 == 0 order by x.Surname select x.Surname; This query would return 100 surnames. The syntax is probably incorrect, but what I need to do is attach an additional where clause and modify the select to a single field. I've been looking into the ExpressionVisitor but I'm not entirely sure how to create a new query based on an existing query. Any guidance would be appreciated. Thanks you.

  • How to avoid "The name 'ConfigurationManager' does not exist in the current context" error?

    - by 5YrsLaterDBA
    I am using VS2008. I have a project connect with a database and the connection string is read from App.config via ConfigurationManager. We are using L2E. Now I added a helper project, AndeDataViewer, to have a simple UI to display data from the database for testing/verification purpose. I don't want to create another set of Entity Data Model in the helper project. I just added all related files as a link in the new helper project. When I compile, I got the following error: Error 15 The name 'ConfigurationManager' does not exist in the current context C:\workspace\SystemSoftware\SystemSoftware\src\systeminfo\RuntimeInfo.cs 24 40 AndeDataViewer I think I may need to add another project setting/config related file's link to the helper project from the main project? There is no App.config file in the new helper project. But it looks I cannot add that file's link to the helper project. Any ideas?

  • L2E many to many query

    - by 5YrsLaterDBA
    I have four tables: Users PrivilegeGroups rdPrivileges LinkPrivilege ----------- ---------------- --------------- --------------- userId(pk) privilegeGroupId(pk) privilegeId(pk) privilegeId(pk, fk) privilegeGroupId(fk) name code privilegeGroupId(pk, fk) L2E will not create LinkPrivilege entity for me. So we only have Users, PrivilegeGroups and rdPrivileges entities. PrivilegeGroups and rdPrivileges are many to many relationship. What I need to do is retrieve all code from rdPrivileges table based on a passed in userId. How can I do it? EDIT working code: var acc = from u in db.Users from pg in db.PrivilegeGroups from p in pg.rdPrivileges where u.UserId == userId && u.PrivilegeGroups.PrivilegeGroupId == pg.PrivilegeGroupId select p.Code;

  • Zend_Table_Db and Zend_Paginator and Zend_Paginator_Adapter_DbSelect

    - by Uffo
    I have the following query: $this->select() ->where("`name` LIKE ?",'%'.mysql_escape_string($name).'%') Now I have the Zend_Paginator code: $paginator = new Zend_Paginator( // $d is an instance of Zend_Db_Select new Zend_Paginator_Adapter_DbSelect($d) ); $paginator->getAdapter()->setRowCount(200); $paginator->setItemCountPerPage(15) ->setPageRange(10) ->setCurrentPageNumber($pag); $this->view->data = $paginator; As you see I'm passing the data to the view using $this->view->data = $paginator Before I didn't had $paginator->getAdapter()->setRowCount(200);I could determinate If I have any data or not, what I mean with data, if the query has some results, so If the query has some results I show the to the user, if not, I need to show them a message(No results!) But in this moment I don't know how can I determinate this, since count($paginator) doesn't work anymore because of $paginator->getAdapter()->setRowCount(200);and I'm using this because it taks about 7 sec for Zend_Paginator to count the page numbers. So how can I find If my query has any results?

  • How can I customise Zend_Form regex error messages?

    - by Matt
    I have the following code: $postcode = $form-createElement('text', 'postcode'); $postcode-setLabel('Post code:'); $postcode-addValidator('regex', false, array('/^[a-z]{1,3}[0-9]{1,3} ?[0-9]{1,3}[a-z]{1,3}$/i')); $postcode-addFilters(array('StringToUpper')); $postcode-setRequired(true); It creates an input field in a form and sets a regex validation rule and works just fine. The problem is that the error message it displays when a user enters an invalid postcode is this: 'POSTCODE' does not match against pattern '/^[a-z]{1,3}[0-9]{1,3} ?[0-9]{1,3}[a-z]{1,3}$/i' (where input was POSTCODE) How can I change this message to be a little more friendly?

  • OpenNETCF Signature control question

    - by Vaccano
    I am using the Signature control in OpenNETCF. It works great for most everything I need. However, I need a way invert the signature and load it back in. It has a call to get the "bytes" for the signature (GetSignatureEx()). It returns a byte[] of the signature. This signature can then be loaded back in with LoadSignatureEx(). I can't seem to figure out the system for these bytes. I thought they may be coordinates, but it does not seem so now. If anyone out there knows a way to invert the signature and load it back in, I would be grateful to hear it.

  • extjs - 'Store is undefined'

    - by Jamie
    Hi all, I'm pretty sure this a trivial problem and i'm just being a bit stupid. Your help would be hugely appreciated. In controls/dashboard.js I have: Ext.ill.WCSS.controls.dashboard = { xtype:'portal', region:'center', margins:'35 5 5 0', items:[{ columnWidth: 1, style:'padding:10px', items:[{ title: 'My Cluster Jobs', layout:'fit', html: "test" }] },{ columnWidth: 1, style:'padding:10px', items:[{ title: 'All Cluster Jobs', iconCls: 'icon-queue', html: "test", items: new Ext.grid.GridPanel({ title: 'Cluster Job Queue', store: Ext.ill.WCSS.stores.dashboardClusterJobs, width: 791, height: 333, frame: true, loadMask: true, stateful: false, autoHeight: true, stripeRows: true, floating: false, footer: false, collapsible: false, animCollapse: false, titleCollapse: false, columns:[ { xtype: 'gridcolumn', header: 'Job ID', sortable: true, resizable: true, width: 100, dataIndex: 'JB_job_number', fixed: false }, { xtype: 'gridcolumn', header: 'Priority', sortable: true, resizable: true, width: 100, dataIndex: 'JAT_prio', fixed: false }, { xtype: 'gridcolumn', header: 'User', sortable: true, resizable: true, width: 100, dataIndex: 'JB_owner' }, { xtype: 'gridcolumn', header: 'State', sortable: true, resizable: true, width: 100, dataIndex: 'state' }, { xtype: 'gridcolumn', header: 'Date Submitted', sortable: true, resizable: true, width: 100, dataIndex: 'JAT_start_time' }, { xtype: 'gridcolumn', header: 'Queue', sortable: true, resizable: true, width: 100, dataIndex: 'queue_name' }, { xtype: 'gridcolumn', header: 'CPUs', sortable: true, resizable: true, width: 100, dataIndex: 'slots' } ], bbar: { xtype: 'paging', store: 'storeClusterQueue', displayInfo: true, refreshText: 'Retrieving queue status...', emptyMsg: 'No jobs to retrieve', id: 'clusterQueuePaging' } }) }] }] }; Simple enough, note the reference to 'Ext.ill.WCSS.stores.dashboardClusterJobs' So in stores/dashboard.js I just have this: Ext.ill.WCSS.stores.dashboardClusterJobs = new Ext.data.XmlStore({ storeId: 'storeClusterJobs', record: 'job_list', autoLoad: true, url: 'joblist.xml', idPath: 'job_info', remoteSort: false, fields: [ { name: 'JB_job_number' }, { name: 'JAT_prio' }, { name: 'JB_name' }, { name: 'JB_owner' }, { name: 'state' }, { name: 'JAT_start_time' }, { name: 'slots' }, { name: 'queue_name' } ] }); I run the code and I get 'store is undefined' :S It's confusing me a lot. All of the javascripts have been included in the correct order. i.e. <script type="text/javascript" src="/js/portal.js"></script> <script type="text/javascript" src="/js/stores/dashboard.js"></script> <script type="text/javascript" src="/js/controls/dashboard.js"></script> Thanks guys!

  • Is writing eSQL database agnostic?

    - by Robert Koritnik
    Using EF we can use LINQ to read data which is rather simple (especialy using fluent calls), but we have less control unless we write eSQL on our own. Is writing eSQL database actually data store independant code? So if we decide to change data store, can the same statements still be used? Is writing eSQL strings in your code pose any serious security threats similar to writing TSQL statements in plain strings? So we moved to SPs. Could we still mode eSQL scripts outside of code as well and use some other technique to make them a bit more secure?

  • Retrieve EF4 POCOs using WCF REST services starter kit

    - by muruge
    I am using WCF REST service (GET method) to retrieve my EF4 POCOs. The service seem to work just fine. When I query the uri in my browser I get the results as expected. In my client application I am trying to use WCF REST Starter Kit's HTTPExtension method - ReadAsDataContract() to convert the result back into my POCO. This works fine when the POCO's navigation property is a single object of related POCO. The problem is when the navigation property is a collection of related POCOs. The ReadAsDataContract() method throws an exception with message "Object reference not set to an instance of an object." Below are my POCOs. [DataContract(Namespace = "", Name = "Trip")] public class Trip { [DataMember(Order = 1)] public virtual int TripID { get; set; } [DataMember(Order = 2)] public virtual int RegionID { get; set; } [DataMember(Order = 3)] public virtual System.DateTime BookingDate { get; set; } [DataMember(Order = 4)] public virtual Region Region { // removed for brevity } } [DataContract(Namespace = "", Name = "Region")] public class Region { [DataMember(Order = 1)] public virtual int RegionID { get; set; } [DataMember(Order = 2)] public virtual string RegionCode { get; set; } [DataMember(Order = 3)] public virtual FixupCollection<Trip> Trips { // removed for brevity } } [CollectionDataContract(Namespace = "", Name = "{0}s", ItemName = "{0}")] [Serializable] public class FixupCollection<T> : ObservableCollection<T> { protected override void ClearItems() { new List<T>(this).ForEach(t => Remove(t)); } protected override void InsertItem(int index, T item) { if (!this.Contains(item)) { base.InsertItem(index, item); } } } And this is how I am trying retrieve a Region POCO. static void GetRegion() { string uri = "http://localhost:8080/TripService/Regions?id=1"; HttpClient client = new HttpClient(uri); using (HttpResponseMessage response = client.Get(uri)) { Region region; response.EnsureStatusIsSuccessful(); try { region = response.Content.ReadAsDataContract<Region>(); // this line throws exception because Region returns a collection of related trips Console.WriteLine(region.RegionName); } catch (Exception ex) { Console.WriteLine(ex.Message); } } } Would appreciate any pointers.

  • EntityFramework EntityState and databinding along with INotifyPropertyChanged

    - by OffApps Cory
    Hello, all! I have a WPF view that displays a Shipment entity. I have a textblock that contains an asterisk which will alert a user that the record is changed but unsaved. I originally hoped to bind the visibility of this (with converter) to the Shipment.EntityState property. If value = EntityState.Modified Then Return Visibility.Visible Else Return Visibility.Collapsed End If The property gets updated just fine, but the view is ignorant of the change. What I need to know is, how can I get the UI to receive notification of the property change. If this cannot be done, is there a good way of writing my own IsDirty property that handles editing retractions (i.e. if I change the value of a property, then change it back to it's original it does not get counted as an edit, and state remains Unchanged). Any help, as always, will be greatly appreciated. Cory

  • Giving Zend Navigation Pages Multiple ACL Privileges

    - by Sonny
    I'm using Zend_Navigation and am trying to integrate it with Zend_Acl. Each page in the navigation has a privilege attribute. What I can't determine is how to define multiple privileges for a single page. Use case: A page that is for managing users. I want to display that page (in navigation) if the current signed in user's role has add, edit, or delete privileges on the Users resource. Example entry in the navigation XML: <admin_users> <label>Users</label> <route>default</route> <controller>admin</controller> <action>users</action> <resource>Users</resource> <privilege>add,edit,delete</privilege> </admin_users> Using a comma-separated list as above doesn't lend the desired behavior.

  • Windows-mobile app won't run after being closed by Task Manager

    - by pithyless
    I've inherited some windows-mobile code that I've been bringing up-to-date. I've come across a weird bug, and I was hoping that even though a bit vague, maybe it will spark someone's memory: Running the app (which is basically a glorified Forms app with P/Invoke gps code), I switch to the task manager, and close the app via End Task. Seems to exit fine (no errors and disappears from Task Manager). Unfortunately, the app refuses to start a second time until I reboot the phone or reinstall the CAB. What's worse: this bug is reproducible on a HTC Diamond, but works fine (ie. can run again after EndTask) on an HTC HD2. The only thing I can think of is some kind of timing race between a Dispose() and the Task Manager. Any ideas? I'm also thinking of a workaround - I do have a working "Exit Application" routine that correctly cleans up the app; can I catch the EndTask event in the c# code in order to complete a proper cleanup? Maybe I'm just missing the pain point... all ideas welcome :)
