VS 2010 Looking For A More Elegant Solution
Jun 21, 2011I am creating a card game and although I have a solution to my question it feels very forced and awkward.
What I want to be able to do is to iterate through a collection but not necessarily start at the begnining or stop at the end.
Some details/examples. Imagine a game (I'll mentally use Spades) with 4 players.
Player 1 Deals cards to all 4 players which makes Player 2 the first to bid. The rub is that after player 4 bids, player 1 should then get his turn to bid.
Player 1 <-- Dealer
Player 2 <-- First to bid
Player 3
Player 4
I can't just iterate over the collection because a For each p as Player in Players would never make it back to player 1 to allow him to bid. As I said, I can make it work with some nested loops but I'm hoping someone might have a better solution. It certainly feels like there must be one. I run into more of the same as the deal moves around the table and as tricks are taken. If a more detailed example is needed, feel free to let me know.
Most Efficient/Elegant Address Validation?
Oct 15, 2010I made this small location class so that I can better handle address information which I am going to be sending off in requests to the Google Maps API. One thing I have left to do is some validation to make sure that the address has enough information to return a result back. For the application, the level of accuracy should be as loose as a single City (meaning that it should work as long as a zip code or city/state is provided since it will find the geographic center of that area automatically in Google Maps)

Foreign Key Constraint Error / Parent Record Does Exist But Won't Let Child Record Be Created
Feb 21, 2010While I've previously many years of relational databases and procedural languages, I'm stumbling with Visual Basic. In this problem, the simple situation is that I have two files, parent and child. The primary key of the parent file (Area file) is linked by a relation to one of the two fields that makes up the primary key in the child file (Project file) (unique key is formed from 'area' and 'project'). I have the default table adapters created on both files. I have created two maintenance forms showing one each of the two files in datagrid view format.I can create some records in the Parent (Area) file, but when I try to create a record in the child (Project) file, using one of the valid key values from the Area file, I get the 'ForeignKeyConstraint [relation name] requires the child key values [actual value] to exist in the parent table' which I'm absolutely definitely sure it does.
I haven't done any actual coding for those two maintenance forms, just dragged-and-dropped the files from the data sources screen onto separate forms so it creates the controls itself. But I can't work out, if it already knows the data does exist because I can load it back in to the Area maintence form, why it can't check itself to find out the record does exist. Why does it think the record from the parent record doesn't exist? It does exactly the same thing, whether or not the database is in access or SQL Server Express. I have all the latest updates.
Adding Association (link Table Record) Without Creating A New Related Record?
Jul 31, 2011I have two tables Products and Categories with a many to many relationship. I am trying to copy the categories linked to one product (OriginalProduct) to another product (newProduct). The problem is when I execute the SaveChanges() method, I not only get the records in my linking table, but it also creates another copy of the categories in the categories table. I've tried this in many ways but here are the last couple that I've attempted:
' Copy Product/Categories
For Each oneProdCategory In OriginalProduct.Categories
Dim relatedCategory = _productContext.GetObjectByKey(New EntityKey ("ProductInfoEntities.Categories", "RecordId", oneProdCategory.RecordId))

Event After Next Record Has Populated Child Record In A Datagrid?
May 27, 2011Visual Studio Pro 2010 Win 7 64 bit running bootstrapped to a MacBook Pro i5 (blasphemer!!!) works really well though!!New to vb.net, have used vb6 for several years and finding the transition interesting to say the least.I have an access database with a vb.net front end all auto bound by the connection and binding wizards (I know, I know...) Not too complicated, but a simple 2 table related db. On the form the parent table shows customer details with the child table related and displayed by datagrid. I have a field in the child table for images and I have figured out how to store and retrieve images to the db. I am using the datagrid.rowheadermouseclick event to reload the picturebox on the main form as I click down the child table datagrid. Now I need to be able to click the bindingnavigator, go to the next record and have the program reload the image for the next child record. The problem is I'm trying to use an event from either the datagrid or bindingnavigator to reload the picturebox in the child table after moving to the next record, but all of the events I am trying are firing before the next record is moved to and therefor the logic I'm using to retrieve the image from the db is not working.
Anyone with an idea on how to move to the next record and then run my logic to populate the picturebox? What events might I use that fire after the next record has been populated? I know this is probably not that hard, but I have been racking my brain all day now.
