      @ Jay

      Lyudmila is correct. Tried in code also.
      context2 EntityState is Unchanged if u go with B so no update to db, if u try C then EntityState is Modified and u will update db.

    • Lyudmyla from Ukraine 02 13 2012, 1:32 PM Report Spam

      Let's look at variant B, you mentioned:
      context2.ApplyCurrentValues("Parts", part1);

      Here part1 object is attached to context. By the second line we try to apply current values, but we pass object part1 again. So, no changes would be detected because objects are the same.
      And only if objects are different in context and in passing arguments, applying changes will take effect.
      And exactly this situation is described in link I gave. That's why my answer is:

      context2.ObjectStateManager.ChangeObjectState(part1, System.Data.EntityState.Modified);

    • Oleksandr from Germany 02 13 2012, 10:09 AM Report Spam

      the reason because I choose the answer B is the following:

      according to this link
      we need to check the ID of the object part1. If it is not 0, then this object is not new and needs to be updated. And I think that part1.PartId is not 0, because we've retrieved it from DB via context1.

      But if you've checked it with code developing, I'll take your answer :-)

      @Oleksandr and @Jay

      Guys, according to this link
      the answer B is not correct. And actually I checked this question and answers on code developing and in my case only variant C worked:

      context2.ObjectStateManager.ChangeObjectState(part1, System.Data.EntityState.Modified);

      Did anyone else check this question via code to be sure?

    • Oleksandr from Germany 02 12 2012, 8:52 PM Report Spam

      I would choose the answer B:
      context2.ApplyCurrentValues("Parts", part1);

      Here is the reference:

      "If the object being attached has updated property values, use one of the following methods [...] System.Data.Objects.ObjectContext.ApplyCurrentValues()" (c)

      I think this is exactly our case, because part1 is the attached object with updated property values:
      4. Updates the data in part1.
      5. Updates the database by using a new ContosoEntities context object named context2.

      But wait for Lyudmyla's comment…

    • Jay from United Kingdom 02 12 2012, 7:34 PM Report Spam
      @azzlack & @Lyudmyla

      There is one question were you are opting for contradictory answers. Would be grateful if you could verify which one is correct.

      You are adding a process to the application. The process performs the following actions:

      1. Opens a ContosoEntities context object named context1.
      2. Loads a Part object into a variable named part1.
      3. Calls the Dispose() method on context1.
      4. Updates the data in part1.
      5. Updates the database by using a new ContosoEntities context object named context2.




      context2.ObjectStateManager.ChangeObjectState(part1, System.Data.EntityState.Modified);

    • hen from Germany 02 04 2012, 9:09 AM Report Spam
      thanks alot!
    • Lyudmyla from Ukraine 02 03 2012, 9:19 AM Report Spam
      @Hen correct one is:
      IEnumerable<Tuple<int, Part>> result = part.Descendants
      .GroupBy(p => p)
      .Select(g => Tuple.Create(g.Count(), g.Key));

      If you make distinct() before groupBy(), you will receive all parts with count 1.

    • Hen from Germany 02 03 2012, 9:11 AM Report Spam
      Okay the following seems right:
      IEnumerable<Tuple<int, Part>> result = part.Descendants
      .GroupBy(p => p)
      .Select(g => Tuple.Create(g.Count(), g.Key));

      Because I had 100% in the "Querying Data" and "Manipulating Data" parts of my exam.

      Thx for the dumbs!!!

    • Hen from Germany 02 02 2012, 1:10 PM Report Spam
      In this dumb there is the following question:
      The application must provide a component part list for any product. The component part list must give the quantity of
      each distinct part that is required to manufacture that product.

      You need to create a LINQ expression that deliversa a result of type IEnumerable<Tuple<int,Part>> to meet the
      Which expression should you use?

      -> the answer in the dumb is:
      IEnumerable<Tuple<int, Part>> result = part.Descendants
      .GroupBy(p => p)
      .Select(g => Tuple.Create(g.Count(), g.Key));

      But what about the following answer:
      IEnumerable<Tuple<int, Part>> result = part.Descendants
      .GroupBy(p => p)
      .Select(g => Tuple.Create(g.Count(), g.Key));

      I guess this one is right…
      Any comments?
      Best wishes, Hen

    • JPD from India 01 28 2012, 8:35 AM Report Spam
      Passed the exam 920/1000 an hr back with MK, Azzlack, dxjonet and stalker.
      3 new questions
      1. Entities – States Class, Cities, Delete of state id raises which exception – (EntityException, Constraint Exception, Update Exception, ENtityUpdateException)
      2. Class Workflow – Has Workstepflow inside. Get workflow data as well as related workstepflow. Dont rem options
      3.You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to develop an application. You use the ADO.NET Entity Framework Designer to model entities.

      You need to create a Plain Old CLR Object (POCO) class that can be used with the ObjectContext.CreateObject method to create a proxy.

      What should you do?
      Ans – Create a custom data class in which all properties and methods are Virtual.

      All, pls go through Training kit, MK, Azzlack, dxjonet and stalker dumps.
      Please double check all ans in dumps

      Troll , the questions which I included in the link are the new questions which I faced in the exam last week :) the testlet question " the new one" was an image that include a function mapping for a stored procedure the SP return a collection of products"you have to figure that by ur self :p" and you have to choose the collection type for the function import:

      A- choose parts from entities.
      B- choose a scaler with Int32
      C- Choose a string scaler.
      D- create a complex type and name it products.

      The answer is D.

      I will include the rest in the dumb or if you have time to help me in creating the new dump i will be happy :)

    • Umair from United Kingdom 01 03 2012, 3:42 PM Report Spam
      Cleared my exam with 920 marks on 21st 12ember 2011.
      MK and Azzlack's dumps are good.
      All the questions in testlet was from Azzlack.
      Around 40% questions were different in the main test as compared to what you find in MK.
      So, I would say that better go through the book first and then do these dumps.
    • vesela from Bulgaria 12 29 2011, 11:09 AM Report Spam
      Testlet of MK + Azzlack helped me a lot to pass on 21.12 in Bulgaria 960 points. Testlet is the same, but there are 20-23 new questions of 60. Most of the new questions are connected to ADO.NET and LINQ to SQL, but the most difficult questions in my oppinion (connections, security) are from the azzlack test. There are lots of questions about Entity Framework and data access with entity sql that the azzlack contains too. Thank you azzlack and MK
