• game play strategy in an arena

  - by joulesm

  I am writing a player's behavior for an arena game, and I'm wondering if you can offer some strategies. I'm writing it in Python, but I'm just interested in the high level game play. Here are the game aspects: Arena is a circle of a given size. The arena size shrinks every round to help break ties. Players are much smaller circles, can be on teams of 1 or 2 players. Players attack by colliding with other players, and based on the physics of the collision (speed of both players, angle), one could force another player out of the arena. Once a player is out of the arena, they are out of the game (for that round). The goal is to be the only team with players left in the arena. All other players have been pushed (through collisions or mistakes) out of the arena. It is possible for there to be no winner if the last two players exit the arena at the same time. Once the player has been programmed, the game just runs. There is no human intervention in the game. I'm thinking it's easiest to implement a few simple programmatic rules for my player to follow. For example, stay close to center of the arena, attack opponents from the inner side of the arena, etc. Are there any good simple game strategies? Would adding a random aspect to the game help? For example, to avoid predictability by the other team or something. Thanks in advance.

• How can I play 24Bit 96000Hz vinyl rips?

  - by Peter

  I am getting music through the Nvidia HDMI but it is all down-sampled to 44000Hz. I have spent at least 3 hours searching for an answer yesterday. I use Pulse Volume and I even changed the default settings in the Pulse folder to 96000 but it does not work. Though 5.1 sound works perfectly. They all work well in Windows 7, but I prefer to use Ubuntu. All the config files for all the programs are in the etc folder, then look in the pulse folder, and there are 3 three files, 2 of these I changed the permissions and I changed 16 and 44000 to 24 and 96000 as I had read in another forum, but it worked for them and not for me. Though 5.1 works as I have special mp4 file that can check each channel. I did alot of restarts and checking after these changes as nothing had happened, my amp tells me the freq of the signal, which does work which I have tested on Windows 7. I have also gone to systems to download the latest driver for mu Nvidia card. But even if it does not work, I guess I can always play Cd's. But I think my player have become more unstable since I changed the configs, so I may uninstall and install Pulse Volume Control again.

• ubuntu 12.04 will not play DVDs

  - by ayelet

  First off, I'm not just a newbie, I'm clueless! So your answers will need to be in complete idiot language (let's say I'm computer saavy, and I can follow directions,but I've never programmed anything and assume I don't understand any abbreviations. So why am I running linux? b/c windows was driving me nuts!! and my friend convinced me. day-to-day operations, we're doing fine, but when it comes to problems, I've got no clue what I'm doing!) So here's what's going on, my machine is an HP pavilion dv6, my optical drive is a standard cd/dvdrw, when i load an audio cd of any type (burned, official, etc,..) I have no problems, when I pop in a dvd - i get nothing. the dvd icon comes up in my launch tray, when I open VLC player I can find the dvd in the folder... but it won't play. I can watch movies I've downloaded with no problem, I can also watch movies off an external hard drive. The only thing I've tried is removing vlc and reinstalling, and I tried installing a different player (gnome maybe? I don't remember). none of that worked. Again, i can follow directions, but you need to be very specific and don't assume I know anything going in. (I mean, I know basic stuff, but nothing too technical.) PLEASE HELP!!! MY KIDS ARE DRIVING ME CRAZY!!! Thanks!!

• how to enable SQL Application Role via Entity Framework

  - by Ehsan Farahani

  I'm now developing big government application with entity framework. at first i have one problem about enable SQL application role. with ado.net I'm using below code: SqlCommand cmd = new SqlCommand("sys.sp_setapprole"); cmd.CommandType = CommandType.StoredProcedure; cmd.Connection = _sqlConn; SqlParameter paramAppRoleName = new SqlParameter(); paramAppRoleName.Direction = ParameterDirection.Input; paramAppRoleName.ParameterName = "@rolename"; paramAppRoleName.Value = "AppRole"; cmd.Parameters.Add(paramAppRoleName); SqlParameter paramAppRolePwd = new SqlParameter(); paramAppRolePwd.Direction = ParameterDirection.Input; paramAppRolePwd.ParameterName = "@password"; paramAppRolePwd.Value = "123456"; cmd.Parameters.Add(paramAppRolePwd); SqlParameter paramCreateCookie = new SqlParameter(); paramCreateCookie.Direction = ParameterDirection.Input; paramCreateCookie.ParameterName = "@fCreateCookie"; paramCreateCookie.DbType = DbType.Boolean; paramCreateCookie.Value = 1; cmd.Parameters.Add(paramCreateCookie); SqlParameter paramEncrypt = new SqlParameter(); paramEncrypt.Direction = ParameterDirection.Input; paramEncrypt.ParameterName = "@encrypt"; paramEncrypt.Value = "none"; cmd.Parameters.Add(paramEncrypt); SqlParameter paramEnableCookie = new SqlParameter(); paramEnableCookie.ParameterName = "@cookie"; paramEnableCookie.DbType = DbType.Binary; paramEnableCookie.Direction = ParameterDirection.Output; paramEnableCookie.Size = 1000; cmd.Parameters.Add(paramEnableCookie); try { cmd.ExecuteNonQuery(); SqlParameter outVal = cmd.Parameters["@cookie"]; // Store the enabled cookie so that approle can be disabled with the cookie. _appRoleEnableCookie = (byte[]) outVal.Value; } catch (Exception ex) { result = false; msg = "Could not execute enable approle proc." + Environment.NewLine + ex.Message; } But no matter how much I searched I could not find a way to implement on EF. Another question is: how to Add Application Role to Entity data model designer? I'm using the below code for execute parameter with EF: AEntities ar = new AEntities(); DbConnection con = ar.Connection; con.Open(); msg = ""; bool result = true; DbCommand cmd = con.CreateCommand(); cmd.CommandType = CommandType.StoredProcedure; cmd.Connection = con; var d = new DbParameter[]{ new SqlParameter{ ParameterName="@r", Value ="AppRole",Direction = ParameterDirection.Input} , new SqlParameter{ ParameterName="@p", Value ="123456",Direction = ParameterDirection.Input} }; string sql = "EXEC " + procName + " @rolename=@r,@password=@p"; var s = ar.ExecuteStoreCommand(sql, d); When run ExecuteStoreCommand this line return error: Application roles can only be activated at the ad hoc level.

• ADO.NET Data Services Entity Framework request error when property setter is internal

  - by Jim Straatman

  I receive an error message when exposing an ADO.NET Data Service using an Entity Framework data model that contains an entity (called "Case") with an internal setter on a property. If I modify the setter to be public (using the entity designer), the data services works fine. I don’t need the entity "Case" exposed in the data service, so I tried to limit which entities are exposed using SetEntitySetAccessRule. This didn’t work, and service end point fails with the same error. public static void InitializeService(IDataServiceConfiguration config) { config.SetEntitySetAccessRule("User", EntitySetRights.AllRead); } The error message is reported in a browser when the .svc endpoint is called. It is very generic, and reads “Request Error. The server encountered an error processing the request. See server logs for more details.” Unfortunately, there are no entries in the System and Application event logs. I found this stackoverflow question that shows how to configure tracing on the service. After doing so, the following NullReferenceExceptoin error was reported in the trace log. Does anyone know how to avoid this exception when including an entity with an internal setter?

• Defining an Entity Framework 1:1 association

  - by Craig Fisher

  I'm trying to define a 1:1 association between two entities (one maps to a table and the other to a view - using DefinedQuery) in an Entity Framework model. When trying to define the mapping for this in the designer, it makes me choose the (1) table or view to map the association to. What am I supposed to choose? I can choose either of the two tables but then I am forced to choose a column from that table (or view) for each end of the relationship. I would expect to be able to choose a column from one table for one end of the association and a column from the other table for the other end of the association, but there's no way to do this. Here I've chosen to map to the "DW_ WF_ClaimInfo" view and it is forcing me to choose two columns from that view - one for each end of the relationship. I've also tried defining the mapping manually in the XML as follows: <AssociationSetMapping Name="Entity1Entity2" TypeName="ClaimsModel.Entity1Entity2" StoreEntitySet="Entity1"> <EndProperty Name="Entity2"> <ScalarProperty Name="DOCUMENT" ColumnName="DOCUMENT" /> </EndProperty> <EndProperty Name="Entity1"> <ScalarProperty Name="PK_DocumentId" ColumnName="PK_DocumentId" /> </EndProperty> </AssociationSetMapping> But this gives: Error 2010: The Column 'DOCUMENT' specified as part of this MSL does not exist in MetadataWorkspace. Seems like it still expects both columns to come from the same table, which doesn't make sense to me. Furthermore, if I select the same key for each end, e.g.: <AssociationSetMapping Name="Entity1Entity2" TypeName="ClaimsModel.Entity1Entity2" StoreEntitySet="Entity1"> <EndProperty Name="Entity2"> <ScalarProperty Name="DOCUMENT" ColumnName="PK_DocumentId" /> </EndProperty> <EndProperty Name="Entity1"> <ScalarProperty Name="PK_DocumentId" ColumnName="PK_DocumentId" /> </EndProperty> </AssociationSetMapping> I then get: Error 3021: Problem in Mapping Fragment starting at line 675: Each of the following columns in table AssignedClaims is mapped to multiple conceptual side properties: AssignedClaims.PK_DocumentId is mapped to <AssignedClaimDW_WF_ClaimInfo.DW_WF_ClaimInfo.DOCUMENT, AssignedClaimDW_WF_ClaimInfo.AssignedClaim.PK_DocumentId> What am I not getting?

• Entity Framework won't SaveChanges on new entity with two-level relationship

  - by Tim Rourke

  I'm building an ASP.NET MVC site using the ADO.NET Entity Framework. I have an entity model that includes these entities, associated by foreign keys: Report(ID, Date, Heading, Report_Type_ID, etc.) SubReport(ID, ReportText, etc.) - one-to-one relationship with Report. ReportSource(ID, Name, Description) - one-to-many relationship with Sub_Report. ReportSourceType(ID, Name, Description) - one-to-many relationship with ReportSource. Contact (ID, Name, Address, etc.) - one-to-one relationship with Report_Source. There is a Create.aspx page for each type of SubReport. The post event method returns a new Sub_Report entity. Before, in my post method, I followed this process: Set the properties for a new Report entity from the page's fields. Set the SubReport entity's specific properties from the page's fields. Set the SubReport entity's Report to the new Report entity created in 1. Given an ID provided by the page, look up the ReportSource and set the Sub_Report entity's ReportSource to the found entity. SaveChanges. This workflow succeeded just fine for a couple of weeks. Then last week something changed and it doesn't work any more. Now instead of the save operation, I get this Exception: UpdateException: "Entities in 'DIR2_5Entities.ReportSourceSet' participate in the 'FK_ReportSources_ReportSourceTypes' relationship. 0 related 'ReportSourceTypes' were found. 1 'Report_Source_Types' is expected." The debug visualizer shows the following: The SubReport's ReportSource is set and loaded, and all of its properties are correct. The Report_Source has a valid ReportSourceType entity attached. In SQL Profiler the prepared SQL statement looks OK. Can anybody point me to what obvious thing I'm missing? TIA Notes: The Report and SubReport are always new entities in this case. The Report entity contains properties common to many types of reports and is used for generic queries. SubReports are specific reports with extra parameters varying by type. There is actually a different entity set for each type of SubReport, but this question applies to all of them, so I use SubReport as a simplified example.

• Zend Framework + Uplodify Flash Uploader Troubles

  - by Richard Knop

  I've been trying to get the Uploadify flash uploader (www.uploadify.com) to work with Zend Framework, with no success so far. I have placed all Uploadify files under /public/flash-uploader directory. In the controller I include all required files and libraries like this: $this->view->headScript()->appendFile('/js/jquery-1.3.2.min.js'); $this->view->headLink()->appendStylesheet('/flash-uploader/css/default.css'); $this->view->headLink()->appendStylesheet('/flash-uploader/css/uploadify.css'); $this->view->headScript()->appendFile('/flash-uploader/scripts/swfobject.js'); $this->view->headScript()->appendFile('/flash-uploader/scripts/jquery.uploadify.v2.1.0.min.js'); And then I activate the plugin like this (#photo is id of the input file field): $(document).ready(function() { $("#photo").uploadify({ 'uploader' : '/flash-uploader/scripts/uploadify.swf', 'script' : 'my-account/flash-upload', 'cancelImg' : '/flash-uploader/cancel.png', 'folder' : 'uploads/tmp', 'queueID' : 'fileQueue', 'auto' : true, 'multi' : true, 'sizeLimit' : 2097152 }); }); As you can see I am targeting the my-account/flash-upload script as a backend processing (my-account is a controller, flash-upload is an action). My form markup looks like this: <form enctype="multipart/form-data" method="post" action="/my-account/upload-public-photo"><ol> <li><label for="photo" class="optional">File Queue<div id="fileQueue"></div></label> <input type="hidden" name="MAX_FILE_SIZE" value="31457280" id="MAX_FILE_SIZE" /> <input type="file" name="photo" id="photo" class="input-file" /></li> <li><div class="button"> <input type="submit" name="upload_public_photo" id="upload_public_photo" value="Save" class="input-submit" /></div></li></ol></form> And yet it's not working. The browse button doesn't even show up as in the demo page, I get only a regular input file field. Any ideas where could the problem be? I've already been staring into the code for hours and I cannot see any mistake anywhere and I'm starting to be exhausted after going through the same 30 lines of code 30 times in a row.

• Global Entity Framework Context in WPF Application

  - by OffApps Cory

  Good day, I am in the middle of development of a WPF application that is using Entity Framework (.NET 3.5). It accesses the entities in several places throughout. I am worried about consistency throughout the application in regard to the entities. Should I be instancing separate contexts in my different views, or should I (and is a a good way to do this) instance a single context that can be accessed globally? For instance, my entity model has three sections, Shipments (with child packages and further child contents), Companies/Contacts (with child addresses and telephones), and disk specs. The Shipments and EditShipment views access the DiskSpecs, and the OptionsView manages the DiskSpecs (Create, Edit, Delete). If I edit a DiskSpec, I have to have something in the ShipmentsView to retrieve the latest specs if I have separate contexts right? If it is safe to have one overall context from which the rest of the app retrieves it's objects, then I imagine that is the way to go. If so, where would that instance be put? I am using VB.NET, but I can translate from C# pretty good. Any help would be appreciated. I just don't want one of those applications where the user has to hit reload a dozen times in different parts of the app to get the new data. Update: OK so I have changed my app as follows: All contexts are created in Using Blocks to dispose of them after they are no longer needed. When loaded, all entities are detatched from context before it is disposed. A new property in the MainViewModel (ContextUpdated) raises an event that all of the other ViewModels subscribe to which runs that ViewModels RefreshEntities method. After implementing this, I started getting errors saying that an entity can only be referenced by one ChangeTracker at a time. Since I could not figure out which context was still referencing the entity (shouldn't be any context right?) I cast the object as IEntityWithChangeTracker, and set SetChangeTracker to nothing (Null). This has let to the current problem: When I Null the changeTracker on the Entity, and then attach it to a context, it loses it's changed state and does not get updated to the database. However if I do not null the change tracker, I can't attach. I have my own change tracking code, so that is not a problem. My new question is, how are you supposed to do this. A good example Entity query and entity save code snipped would go a long way, cause I am beating my head in trying to get what I once thought was a simple transaction to work. Any help would elevate you to near god-hood.

• Tree Node Checked behavior on a TreeView in Compact Framework 3.5 running on Windows Mobile 6.5

  - by Hydroslide

  I have been upgrading an existing .NET Windows Mobile application to use the 3.5 version of the compact framework and to run on Windows Mobile 6.5. I have a form with a TreeView. The TreeView.Checkboxes property is set to true so that each node has a check box. This gives no trouble in all previous versions of Windows Mobile. However, in version 6.5 when you click on a check box it appears to check and then uncheck instantaneously. But it only raises the AfterCheck event once. The only way I can get a check to stick is by double clicking it (which is the wrong behavior). Has anyone seen this behavior? Does anyone know of a workaround for it? I have included a simple test form. Dump this form into a Visual Studio 2008 Smart Device application targeted at Windows Mobile 6 to see what I mean. Public Class frmTree Inherits System.Windows.Forms.Form #Region " Windows Form Designer generated code " Public Sub New() MyBase.new() ' This call is required by the Windows Form Designer.

• Retrieving/Updating Entity Framework POCO objects that already exist in the ObjectContext

  - by jslatts

  I have a project using Entity Framework 4.0 with POCOs (data is stored in SQL DB, lazyloading is enabled) as follows: public class ParentObject { public int ID {get; set;} public virtual List<ChildObject> children {get; set;} } public class ChildObject { public int ID {get; set;} public int ChildRoleID {get; set;} public int ParentID {get; set;} public virtual ParentObject Parent {get; set;} public virtual ChildRoleObject ChildRole {get; set;} } public class ChildRoleObject { public int ID {get; set;} public string Name {get; set;} public virtual List<ChildObject> children {get; set;} } I want to create a new ChildObject, assign it a role, then add it to an existing ParentObject. Afterwards, I want to send the new ChildObject to the caller. The code below works fine until it tries to get the object back from the database. The newChildObjectInstance only has the ChildRoleID set and does not contain a reference to the actual ChildRole object. I try and pull the new instance back out of the database in order to populate the ChildRole property. Unfortunately, in this case, instead of creating a new instance of ChildObject and assigning it to retreivedChildObject, EF finds the existing ChildObject in the context and returns the in-memory instance, with a null ChildRole property. public ChildObject CreateNewChild(int id, int roleID) { SomeObjectContext myRepository = new SomeObjectContext(); ParentObject parentObjectInstance = myRepository.GetParentObject(id); ChildObject newChildObjectInstance = new ChildObject() { ParentObject = parentObjectInstance, ParentID = parentObjectInstance.ID, ChildRoleID = roleID }; parentObjectInstance.children.Add(newChildObjectInstance); myRepository.Save(); ChildObject retreivedChildObject = myRepository.GetChildObject(newChildObjectInstance.ID); string assignedRoleName = retreivedChildObject.ChildRole.Name; //Throws exception, ChildRole is null return retreivedChildObject; } I have tried setting MergeOptions to Overwrite, calling ObjectContext.Refresh() and ObjectContext.DetectChanges() to no avail... I suspect this is related to the proxy objects that EF injects when working with POCOs. Has anyone run into this issue before? If so, what was the solution?

• Entity Framework looking for wrong column

  - by m.edmondson

  I'm brand new to the Entity Framework and trying to learn all it can offer. I'm currently working my way through the MVC Music Store tutorial which includes the following code: public ActionResult Browse(string genre) { // Retrieve Genre and its Associated Albums from database var genreModel = storeDB.Genres.Include("Albums") .Single(g => g.Name == genre); return View(genreModel); } as I'm working in VB I converted it like so: Function Browse(ByVal genre As String) As ActionResult 'Retrieve Genre and its Associated Albums from database Dim genreModel = storeDB.Genres.Include("Albums"). _ Single(Function(g) g.Name = genre) Return(View(genreModel)) End Function The problem is I'm getting the following exception: Invalid column name 'GenreGenreId'.

• .Net Entity Framework SaveChanges is adding without add method

  - by tmfkmoney

  I'm new to the entity framework and I'm really confused about how savechanges works. There's probably a lot of code in my example which could be improved, but here's the problem I'm having. The user enters a bunch of picks. I make sure the user hasn't already entered those picks. Then I add the picks to the database. var db = new myModel() var predictionArray = ticker.Substring(1).Split(','); // Get rid of the initial comma. var user = Membership.GetUser(); var userId = Convert.ToInt32(user.ProviderUserKey); // Get the member with all his predictions for today. var memberQuery = (from member in db.Members where member.user_id == userId select new { member, predictions = from p in member.Predictions where p.start_date == null select p }).First(); // Load all the company ids. foreach (var prediction in memberQuery.predictions) { prediction.CompanyReference.Load(); } var picks = from prediction in predictionArray let data = prediction.Split(':') let companyTicker = data[0] where !(from i in memberQuery.predictions select i.Company.ticker).Contains(companyTicker) select new Prediction { Member = memberQuery.member, Company = db.Companies.Where(c => c.ticker == companyTicker).First(), is_up = data[1] == "up", // This turns up and down into true and false. }; // Save the records to the database. // HERE'S THE PART I DON'T UNDERSTAND. // This saves the records, even though I don't have db.AddToPredictions(pick) foreach (var pick in picks) { db.SaveChanges(); } // This does not save records when the db.SaveChanges outside of a loop of picks. db.SaveChanges(); foreach (var pick in picks) { } // This saves records, but it will insert all the picks exactly once no matter how many picks you have. //The fact you're skipping a pick makes no difference in what gets inserted. var counter = 1; foreach (var pick in picks) { if (counter == 2) { db.SaveChanges(); } counter++; } There's obviously something going on with the context I don't understand. I'm guessing I've somehow loaded my new picks as pending changes, but even if that's true I don't understand I have to loop over them to save changes. Can someone explain this to me?

• flash.media.Sound.play takes long time to return

  - by Fire Lancer

  I'm trying to play some sounds in my flash project through action script. However for some reason in my code the call to Sound.play takes from 40ms to over 100ms in extreme cases, which is obviously more than enough to be very noticeable whenever a sound is played. This happens every time a sound is played, not just when that sound is first played, so I dont think its because the Sound object is still loading data or anything like that... At the start I have this to load the sound: class MyClass { [Embed(source='data/test_snd.mp3')] private var TestSound:Class; private var testSound:Sound;//flash.media.Sound public function MyClass() { testSound = new TestSound(); } Then im just using the play method of the sound object to play it later on. testSound.play();//seems to take a long time to return This as far as I can tell is following the same process as other Flash programs I found, however none of them seem to have this problem. Is there something that I've missed that would cause the play() method to be so slow?

• Entity framework 4 many-to-many insertion?

  - by Saxman

  Hi all, I'm not very familiar with the many-to-many insertion process using Entity Framework 4, POCO. I have a blog with 3 tables: Post, Comment, and Tag. A Post can have many Tags and a Tag can be in many Posts. Here are the Post and Tag models: public class Tag { public int Id { get; set; } [Required] [StringLength(25, ErrorMessage = "Tag name can't exceed 25 characters.")] public string Name { get; set; } public virtual ICollection<Post> Posts { get; set; } } public class Post { public int Id { get; set; } [Required] [StringLength(512, ErrorMessage = "Title can't exceed 512 characters")] public string Title { get; set; } [Required] [AllowHtml] public string Content { get; set; } public string FriendlyUrl { get; set; } public DateTime PostedDate { get; set; } public bool IsActive { get; set; } public virtual ICollection<Comment> Comments { get; set; } public virtual ICollection<Tag> Tags { get; set; } } Now when I'm adding a new post, I'm not sure what would be the right way to do. I'm thinking that I'll have a textbox where I can select multiple tags for that post (this part is already done), in my controller, I will check to see if the tag is already exists or not, if not, then I will insert the new tag. But I'm not even sure based on the models that I've created for EF, will they create a PostsTags table, or they are creating just a Tags and a Posts table and links between the two? How would I insert the new Post and set the tags to that post? Is it just newPost.Tags = Tags (where Tags are the one that got selected, do I even need to check to see if they already exists?), and then something like _post.Add(newPost);? Thanks.

• Entity Framework: An object with the same key already exists in the objectstatemanager

  - by NealR

  I see that this question has been asked a lot, however I haven't found anything yet that solves the problem I'm having. Obviously i'm using the Entity Framework to perform an update to a record. Once the updates are complete, however, whenever I try to save I get the following error message: An object with the same key already exists in the objectstatemanager At first I was passing in a collection object from the view that contained a copy of the the ZipCodeTerritory model object zipToUpdate. I changed the code by pulling this object out and just sending in the relevant fields instead. However, I'm still getting the same error. What's also weird is the first time I run this code, it works fine. Any attempt after that I get the error. Controller Here is the code from the method calling the edit function public static string DescriptionOnly(ZipCodeIndex updateZip) { if (!string.IsNullOrWhiteSpace(updateZip.newEffectiveDate) || !string.IsNullOrWhiteSpace(updateZip.newEndDate)) { return "Neither effective or end date can be present if updating Territory Code only; "; } _updated = 0; foreach (var zipCode in updateZip.displayForPaging.Where(x => x.Update)) { ProcessAllChanges(zipCode, updateZip.newTerritory, updateZip.newStateCode, updateZip.newDescription, updateZip.newChannelCode); } _msg += _updated + " record(s) updated; "; return _msg; } And here is the method that actually does the updating. private static void ProcessAllChanges(ZipCodeTerritory zipToUpdate, string newTerritory, string newStateCode, string newDescription, string newChannelCode) { try { if (!string.IsNullOrWhiteSpace(newTerritory)) zipToUpdate.IndDistrnId = newTerritory; if (!string.IsNullOrWhiteSpace(newStateCode)) zipToUpdate.StateCode = newStateCode; if (!string.IsNullOrWhiteSpace(newDescription)) zipToUpdate.DrmTerrDesc = newDescription; if (!string.IsNullOrWhiteSpace(newChannelCode)) zipToUpdate.ChannelCode = newChannelCode; if (zipToUpdate.EndDate == DateTime.MinValue) zipToUpdate.EndDate = DateTime.MaxValue; _db.Entry(zipToUpdate).State = EntityState.Modified; _db.SaveChanges(); _updated++; } catch (DbEntityValidationException dbEx) { _msg += "Error during update; "; EventLog.WriteEntry("Monet", "Error during ProcessAllChanges: " + zipToUpdate.ToString() + " |EX| " + dbEx.Message); } catch (Exception ex) { _msg += "Error during update; "; EventLog.WriteEntry("Monet", "Error during ProcessAllChanges: " + zipToUpdate.ToString() + " |MESSAGE| " + ex.Message); } } EDIT The ZipCodeIndex object contains a list of ZipCodeTerritory model objects. These aren't being pulled from a linq query, but instead simply passed back to the controller from the view. Here is the signature of the controller method that starts the process: [HttpPost] public ActionResult Update(ZipCodeIndex updateZip, string button)

• Virtual Economy Setup - Virtual currencies advice

  - by Sarah Simpson

  I'm trying to figure out how to build my virtual economy. It seems like some games have one currency and some of them have up to 3 and 4 different ones. The game is an action game which is currently single player but I'm planning on adding a tournament mode that allows users to compete against each other. The virtual goods that a user would be able to purchase would be either customization to the character or powerups and utilities that give the character more abilities in the game. The character is able to gain coins during game play. The advice I'm trying to get is whether or not it makes sense to set up more than one currency and more than two currencies? What are the pros and cons? Reference to some resources that indicate research would be great.

• Expiring timed actions a good idea?

  - by Bart van Heukelom

  We have an online game where players sometimes have to wait a while (say 30 minutes) before a process they intiated completes. This encourages them to come back later. An example of this is growing crops in Farmville or basically any action in the Sims Play4Free. Now, however, there is the idea to let these processes expire, so if the player doesn't 'reap' them in time (e.g. within 4 hours) they are aborted. I'm a bit sceptical about this. How will this make players come back more often? Is not the reward of reaping the process enough for that? Can we expect players to fit their daily schedule around our game, maybe even set the alarm clock at night? Won't this just cause players to give up on starting these processes in the first place? I realise this may be too subjective for this site, so I'll end with a concrete question: Do (m)any other online free-to-play games employ this technique?

• Entity Framework and multi-tenancy database design

  - by Junto

  I am looking at multi-tenancy database schema design for an SaaS concept. It will be ASP.NET MVC - EF, but that isn't so important. Below you can see an example database schema (the Tenant being the Company). The CompanyId is replicated throughout the schema and the primary key has been placed on both the natural key, plus the tenant Id. Plugging this schema into the Entity Framework gives the following errors when I add the tables into the Entity Model file (Model1.edmx): The relationship 'FK_Order_Customer' uses the set of foreign keys '{CustomerId, CompanyId}' that are partially contained in the set of primary keys '{OrderId, CompanyId}' of the table 'Order'. The set of foreign keys must be fully contained in the set of primary keys, or fully not contained in the set of primary keys to be mapped to a model. The relationship 'FK_OrderLine_Customer' uses the set of foreign keys '{CustomerId, CompanyId}' that are partially contained in the set of primary keys '{OrderLineId, CompanyId}' of the table 'OrderLine'. The set of foreign keys must be fully contained in the set of primary keys, or fully not contained in the set of primary keys to be mapped to a model. The relationship 'FK_OrderLine_Order' uses the set of foreign keys '{OrderId, CompanyId}' that are partially contained in the set of primary keys '{OrderLineId, CompanyId}' of the table 'OrderLine'. The set of foreign keys must be fully contained in the set of primary keys, or fully not contained in the set of primary keys to be mapped to a model. The relationship 'FK_Order_Customer' uses the set of foreign keys '{CustomerId, CompanyId}' that are partially contained in the set of primary keys '{OrderId, CompanyId}' of the table 'Order'. The set of foreign keys must be fully contained in the set of primary keys, or fully not contained in the set of primary keys to be mapped to a model. The relationship 'FK_OrderLine_Customer' uses the set of foreign keys '{CustomerId, CompanyId}' that are partially contained in the set of primary keys '{OrderLineId, CompanyId}' of the table 'OrderLine'. The set of foreign keys must be fully contained in the set of primary keys, or fully not contained in the set of primary keys to be mapped to a model. The relationship 'FK_OrderLine_Order' uses the set of foreign keys '{OrderId, CompanyId}' that are partially contained in the set of primary keys '{OrderLineId, CompanyId}' of the table 'OrderLine'. The set of foreign keys must be fully contained in the set of primary keys, or fully not contained in the set of primary keys to be mapped to a model. The relationship 'FK_OrderLine_Product' uses the set of foreign keys '{ProductId, CompanyId}' that are partially contained in the set of primary keys '{OrderLineId, CompanyId}' of the table 'OrderLine'. The set of foreign keys must be fully contained in the set of primary keys, or fully not contained in the set of primary keys to be mapped to a model. The question is in two parts: Is my database design incorrect? Should I refrain from these compound primary keys? I'm questioning my sanity regarding the fundamental schema design (frazzled brain syndrome). Please feel free to suggest the 'idealized' schema. Alternatively, if the database design is correct, then is EF unable to match the keys because it perceives these foreign keys as a potential mis-configured 1:1 relationships (incorrectly)? In which case, is this an EF bug and how can I work around it?

• Opening an SQL CE file at runtime with Entity Framework 4

  - by David Veeneman

  I am getting started with Entity Framework 4, and I an creating a demo app as a learning exercise. The app is a simple documentation builder, and it uses a SQL CE store. Each documentation project has its own SQL CE data file, and the user opens one of these files to work on a project. The EDM is very simple. A documentation project is comprised of a list of subjects, each of which has a title, a description, and zero or more notes. So, my entities are Subject, which contains Title and Text properties, and Note, which has Title and Text properties. There is a one-to-many association from Subject to Note. I am trying to figure out how to open an SQL CE data file. A data file must match the schema of the SQL CE database created by EF4's Create Database Wizard, and I will implement a New File use case elsewhere in the app to implement that requirement. Right now, I am just trying to get an existing data file open in the app. I have reproduced my existing 'Open File' code below. I have set it up as a static service class called File Services. The code isn't working quite yet, but there is enough to show what I am trying to do. I am trying to hold the ObjectContext open for entity object updates, disposing it when the file is closed. So, here is my question: Am I on the right track? What do I need to change to make this code work with EF4? Is there an example of how to do this properly? Thanks for your help. My existing code: public static class FileServices { #region Private Fields // Member variables private static EntityConnection m_EntityConnection; private static ObjectContext m_ObjectContext; #endregion #region Service Methods /// <summary> /// Opens an SQL CE database file. /// </summary> /// <param name="filePath">The path to the SQL CE file to open.</param> /// <param name="viewModel">The main window view model.</param> public static void OpenSqlCeFile(string filePath, MainWindowViewModel viewModel) { // Configure an SQL CE connection string var sqlCeConnectionString = string.Format("Data Source={0}", filePath); // Configure an EDM connection string var builder = new EntityConnectionStringBuilder(); builder.Metadata = "res://*/EF4Model.csdl|res://*/EF4Model.ssdl|res://*/EF4Model.msl"; builder.Provider = "System.Data.SqlServerCe"; builder.ProviderConnectionString = sqlCeConnectionString; var entityConnectionString = builder.ToString(); // Connect to the model m_EntityConnection = new EntityConnection(entityConnectionString); m_EntityConnection.Open(); // Create an object context m_ObjectContext = new Model1Container(); // Get all Subject data IQueryable<Subject> subjects = from s in Subjects orderby s.Title select s; // Set view model data property viewModel.Subjects = new ObservableCollection<Subject>(subjects); } /// <summary> /// Closes an SQL CE database file. /// </summary> public static void CloseSqlCeFile() { m_EntityConnection.Close(); m_ObjectContext.Dispose(); } #endregion }

• Getting code-first Entity Framework to build tables on SQL Azure

  - by NER1808

  I am new the code-first Entity Framework. I have tried a few things now, but can't get EF to construct any tables in the my SQL Azure database. Can anyone advise of some steps and settings I should check. The membership provider has no problems create it's tables. I have added the PersistSecurityInfo=True in the connection string. The connection string is using the main user account for the server. When I implement the tables in the database using sql everything works fine. I have the following in the WebRole.cs //Initialize the database Database.SetInitializer<ReykerSCPContext>(new DbInitializer()); My DbInitializer (which does not get run before I get a "Invalid object name 'dbo.ClientAccountIFAs'." when I try to access the table for the first time. Sometime after startup. public class DbInitializer:DropCreateDatabaseIfModelChanges<ReykerSCPContext> { protected override void Seed(ReykerSCPContext context) { using (context) { //Add Doc Types context.DocTypes.Add(new DocType() { DocTypeId = 1, Description = "Statement" }); context.DocTypes.Add(new DocType() { DocTypeId = 2, Description = "Contract note" }); context.DocTypes.Add(new DocType() { DocTypeId = 3, Description = "Notification" }); context.DocTypes.Add(new DocType() { DocTypeId = 4, Description = "Invoice" }); context.DocTypes.Add(new DocType() { DocTypeId = 5, Description = "Document" }); context.DocTypes.Add(new DocType() { DocTypeId = 6, Description = "Newsletter" }); context.DocTypes.Add(new DocType() { DocTypeId = 7, Description = "Terms and Conditions" }); //Add ReykerAccounttypes context.ReykerAccountTypes.Add(new ReykerAccountType() { ReykerAccountTypeID = 1, Description = "ISA" }); context.ReykerAccountTypes.Add(new ReykerAccountType() { ReykerAccountTypeID = 2, Description = "Trading" }); context.ReykerAccountTypes.Add(new ReykerAccountType() { ReykerAccountTypeID = 3, Description = "SIPP" }); context.ReykerAccountTypes.Add(new ReykerAccountType() { ReykerAccountTypeID = 4, Description = "CTF" }); context.ReykerAccountTypes.Add(new ReykerAccountType() { ReykerAccountTypeID = 5, Description = "JISA" }); context.ReykerAccountTypes.Add(new ReykerAccountType() { ReykerAccountTypeID = 6, Description = "Direct" }); context.ReykerAccountTypes.Add(new ReykerAccountType() { ReykerAccountTypeID = 7, Description = "ISA & Direct" }); //Save the changes context.SaveChanges(); } and my DBContext class looks like public class ReykerSCPContext : DbContext { //set the connection explicitly public ReykerSCPContext():base("ReykerSCPContext"){} //define tables public DbSet<ClientAccountIFA> ClientAccountIFAs { get; set; } public DbSet<Document> Documents { get; set; } public DbSet<DocType> DocTypes { get; set; } public DbSet<ReykerAccountType> ReykerAccountTypes { get; set; } protected override void OnModelCreating(DbModelBuilder modelBuilder) { //Runs when creating the model.

• Can't install .NET framework 4.0 on Windows XP professional version 2002 SP3 (OS bug?)

  - by that guy

  .NET framework 4.0 install fails on Windows XP professional version 2002 SP3: I tried to run setup using "run as..." to make sure the admin rights are used ("protect my computer..." tick was deselected of course). I tried everything: installing using online/offline setup, windows update. install goes a little and then "rolls back" and says: Installation did not succeed .NET Framework 4 has not been installed because: Fatal error during installation. for more information about this problem, see the log file. the full log: http://pastebay.net/1433771 Any ideas? EDIT1: I have found this in the log: "BlockIf: You must install the 32-bit Windows Imaging Component (WIC) before you run Setup. Please visit the Microsoft Download Center to install WIC, and then rerun Setup...." So I found it, and launched "wic_x86_enu.exe" - but it said: WIC Setup error Newer version of update is already on the system. I have already installed: .NET framewrok 2.0 SP2 .NET framewrok 3.0 SP2 .NET framewrok 3.5 SP1 but I need 4.0 . EDIT2: another attempt and it's log. (this time better copy of log file): http://pastebin.com/gmGfbM9a (copy to notepad and save as .htm and open with internet browser). I have tried all the solutions I could find - and nothing helped. I have found something weird: when I formatted the hard drive and installed windows xp again - the .NET framework 4.0 installed ok, but when I plugged my 100Mbit internet cable - the operating system kind off "locked itself" and the bug returned - I could no longer install .NET framework 4.0 again. There was no reason for that to happen, for example I have windows server 2003 in local network, but I don't have active directory enabled on it or anything like that - the server just has some folders shared and thats all (all server's "features" are default). I had the second pc with the same problem - with XP on it too. This seems like the bug of Operating System to me. I couldn't find what was causing the problem. After many days I gave up: backuped everything, formatted HDD and installed Windows 7 professional 64bit. .NET framework 4.0 installed with no problem on it.

• Multiple Zend application code organisation

  - by user966936

  For the past year I have been working on a series of applications all based on the Zend framework and centered on a complex business logic that all applications must have access to even if they don't use all (easier than having multiple library folders for each application as they are all linked together with a common center). Without going into much detail about what the project is specifically about, I am looking for some input (as I am working on the project alone) on how I have "grouped" my code. I have tried to split it all up in such a way that it removes dependencies as much as possible. I'm trying to keep it as decoupled as I logically can, so in 12 months time when my time is up anyone else coming in can have no problem extending on what I have produced. Example structure: applicationStorage\ (contains all applications and associated data) applicationStorage\Applications\ (contains the applications themselves) applicationStorage\Applications\external\ (application grouping folder) (contains all external customer access applications) applicationStorage\Applications\external\site\ (main external customer access application) applicationStorage\Applications\external\site\Modules\ applicationStorage\Applications\external\site\Config\ applicationStorage\Applications\external\site\Layouts\ applicationStorage\Applications\external\site\ZendExtended\ (contains extended Zend classes specific to this application example: ZendExtended_Controller_Action extends zend_controller_Action ) applicationStorage\Applications\external\mobile\ (mobile external customer access application different workflow limited capabilities compared to full site version) applicationStorage\Applications\internal\ (application grouping folder) (contains all internal company applications) applicationStorage\Applications\internal\site\ (main internal application) applicationStorage\Applications\internal\mobile\ (mobile access has different flow and limited abilities compared to main site version) applicationStorage\Tests\ (contains PHP unit tests) applicationStorage\Library\ applicationStorage\Library\Service\ (contains all business logic, services and servicelocator; these are completely decoupled from Zend framework and rely on models' interfaces) applicationStorage\Library\Zend\ (Zend framework) applicationStorage\Library\Models\ (doesn't know services but is linked to Zend framework for DB operations; contains model interfaces and model datamappers for all business objects; examples include Iorder/IorderMapper, Iworksheet/IWorksheetMapper, Icustomer/IcustomerMapper) (Note: the Modules, Config, Layouts and ZendExtended folders are duplicated in each application folder; but i have omitted them as they are not required for my purposes.) For the library this contains all "universal" code. The Zend framework is at the heart of all applications, but I wanted my business logic to be Zend-framework-independent. All model and mapper interfaces have no public references to Zend_Db but actually wrap around it in private. So my hope is that in the future I will be able to rewrite the mappers and dbtables (containing a Models_DbTable_Abstract that extends Zend_Db_Table_Abstract) in order to decouple my business logic from the Zend framework if I want to move my business logic (services) to a non-Zend framework environment (maybe some other PHP framework). Using a serviceLocator and registering the required services within the bootstrap of each application, I can use different versions of the same service depending on the request and which application is being accessed. Example: all external applications will have a service_auth_External implementing service_auth_Interface registered. Same with internal aplications with Service_Auth_Internal implementing service_auth_Interface Service_Locator::getService('Auth'). I'm concerned I may be missing some possible problems with this. One I'm half-thinking about is a config.ini file for all externals, then a separate application config.ini overriding or adding to the global external config.ini. If anyone has any suggestions I would be greatly appreciative. I have used contextswitching for AJAX functions within the individual applications, but there is a big chance both external and internal will get web services created for them. Again, these will be separated due to authorization and different available services. \applicationstorage\Applications\internal\webservice \applicationstorage\Applications\external\webservice
