Entity Framework 4 and DB2: database generation error -

Entity Framework 4 and DB2: database generation error -

We are using Entity Framework 4 RC on Visual Studio 2010 with DB2 version 9.7.3.4. I also have VS add-ins and can see the DB2 database in server explorer. I have created a very simple VS console project and it works fine against SQL Server, so I know it's valid. I have references to "IBM.Data.DB2.9.7.3" and "IBM.Data.DB2.Entity" in my project.

In the app. My connection string is:

  & lt; Name = = "productcontact" provider name = "IBM data .db2" connection string = "database = db2 test; user id = XXXX; pwd = XXXX; server = XXXX; continue security information = true;" / Gt;    The first statement of my code is a database launcher:  
  DbDatabase.SetInitializer  (New DropCreateDatabaseIfModelChanges  () ;    During the run-time, when I reach a line that causes data change, I get an error:  
  Model Compatibility Can not check because the database does not have model metadata.   
 Because I requested that the database be abandoned, it is not a logical error, does anyone know what the reason might be?   
 
  I will first try to get from CreateDatabaseIfNotExists, which will add the AdmittataData table for schema. I believe the error is that EF is saying that he can not get that table.  <>  DbDatabase.SetInitializer & product;   
 Run it once, then once you have the AdmitTata table, make changes to DropCreateDatabaseIfModel.

Integrate flash games in android app? -



    3 is a flash game that I want to integrate into a menu / list in the Android app. So when the user selects the game from the list, the game starts with the help of the Android Flash Player.   Is it better or better with webwave?   Is there any good tutorial?   Thank you! Adobe Flash provides a good way: you can create a breeze for the Android app.    Use this to create your menu and compile three games in your air app.   Here are some tutorial links about how to publish AiI for Android applications and:   PART1: AIR for Android, PART2:   Publication for Android apps: Ai:   I do not believe that the Android Flash Player can be launched with a single intention so far, so using Java Android will not solve it (now ) And   and a third approach Whatever you mentioned, it should work - using the webwave.
