Yahoo Mail is absolutely worthless

I have been having this problem for over four weeks now.

Every time I log into my yahoo account it shows the message below.

There was a problem accessing your account. Please try again in a moment.
Error #1

Not sure what the cause is but it stops me from accessing my account.

I was able to access my account yesterday via yahoo's widget on their homepage.

I am not sure if you have run into this issue... but incase you have and know the resolution please let me know

.Net 3.5 and Partial Classes and Multi Layered System

.Net 3.5 and Partial Classes and Multi Layered System

I want to break my project down into 3 layers of code.


 I was hoping to be able to simply create partial classes in the Logic library so I would not have create a brand new set of classes
 Unfortunately you can not create partial classes outside the main library which contains your DBML

 I can create a class with the same name under the Test1.Logic namespace, and simply inherit the Test1.Data class.

This gives me all the classes and their methods in the Logic library without a lot of code and now I can build my entire logic in the LOGIC library

Hope this gives you a jump start on your project.

I would use this script to quickly create the LOGIC classes from your DATA classes



      SELECT      Table_Name

      FROM  Information_Schema.Tables

      WHERE Table_Type = 'BASE TABLE'

      ORDER BY Table_Name







      PRINT 'class ' + @TableName + ' : Test1.Data.' + @TableName + '


      } '


      FETCH NEXT FROM tc INTO @TableName






Remember though that you will still need to create the datacontext manually

Have an excellent day.

Cannot add an entity with a key that ...

Cannot add an entity with a key that is already in use

This ERROR has caused me a lot of aggrevation over the last couple of days as a sniplet that I was using earlier all of a sudden stopped working.

And even when I went back and checked the history it showed no change to that code block.

I read a bunch of articles online (for over 3 days) which led me to believe that the problem was with the LINQ framework and not my code.

Despite strongly disagreeing with the idea to add an IDENTITY column, I finally bit the bullet and added the column but still no luck.

I yelled out in pain "WHY THE HELL WOULD THIS NOT WORK" after a couple of sleepless nights, I tried something else, I tried calling the db.SubmitChanges() function in the begining of my function.

P.S. I am extending my datacontext by using Partial Class

So I had code that looked something like this

Partial Class FancyDataContext
 Public Sub AddYahoo()
  Dim db as FancyDataContext = Me
  Dim NewRecord as New FancyRow
  db.Fancy.InsertOnSubmit( NewRecord )

  db.SubmitChanges() 'THIS IS WHERE IT ERRORED OUT

 End Sub
End Class

I tried variations of my code to see if there was something that I could do to fix this code that was working perfectly fine previously.

What I found was simply AMAZING.
I simply chagned my code from above to

Partial Class FancyDataContext
 Public Sub AddYahoo()

  Dim db as FancyDataContext = Me
  Dim NewRecord as New FancyRow
  db.Fancy.InsertOnSubmit( NewRecord )
  db.SubmitChanges() 'THIS IS WHERE IT ERRORED OUT
 End Sub
End Class

And it errored out.
And Ofcourse, what I noticed was that the function calling my AddYahoo() function was making changes to the datacontext that were not being committed in its block and handing my function the bad data

I did a quick search on LINQ Discard Chagnes and used the article on and created the discard function

Public Sub DiscardInsertsAndDeletes(ByVal data As DataContext)
    ' Get the changes
    Dim changes = data.GetChangeSet()
    ' Delete the insertions
    For Each insertion In changes.Inserts
    ' Insert the deletions
    For Each deletion In changes.Deletes
End Sub

So my code now said 

Partial Class FancyDataContext
 Public Sub AddYahoo()

  Dim db as FancyDataContext = Me
  Dim NewRecord as New FancyRow
  db.Fancy.InsertOnSubmit( NewRecord )

  db.SubmitChanges() 'THIS IS NOW WORKING :D YEAY

 End Sub
End Class

So at the end of it all it was human error.

My apologies to the MSFT team for doubting them.

Hope this saves you some aggrevation in the future.

Have an excellent day.
