Foreign characters causing a duplicate attribute key error - how to avoid?

Greetings, We have a data warehouse into which we import data obtained from our outside vendors.  The data are then used to build data cubes.  Lately we have started to get a duplicate key error on the "County" attribute in our "Location" dimension.  The problem appears to be caused by these two values returned by the query that returns the distinct list of counties: Spree-Neisse Spree-Neiße These are German counties and they are really the same county, I believe.  Our data warehouse stores County as a varchar.  If I cast the stored value as nvarchar, the query that returns the distinct list of counties returns only the 2nd value and so should avoid the duplicate key error.  (I haven't tried it yet, just speculating.) This post suggests the root cause of the problem: http://ssas-musings.blogspot.com/2009/11/duplicate-key-error.html We don't have any control over the data before our vendors give it to us, and it comes from all over the world.  What is the best way to avoid occurrences of the duplicate attribute key error?  Should we be storing all our character data as nvarchar?  Would it be enough to cast the stored data as nvarchar when the cubes are being built?  Is there a better approach?  I'd like to get an idea of what the best practice would be.  Our warehouse

basic question about foreign key nocheck


I don't really want to have FK on some reporting tables, but for obscure reasons I need to define them anyway. 

I thought if I added them "nocheck" they were there but disabled.

I was able to run SSIS packages to load five interrelated tables in any order, and never got any complaints!

But just now, I did an insert of some rows on top of other rows, and got FK errors, even on my nocheck'd FKs.

So, ... "nocheck" just means not to check the existing data, but any new data *is* checked after all?

Is that right?

I guess the bulk (fast) load from SSIS manages to bypass this too?

So, there's no further way to disable the FKs, is there?




Filtering foreign key drop down list question.


I have a question concerning the way dynamic data filters records in foreign key fields in edit mode.  Here is my application as an example:


I have a table called people which has a one to many relationship to a table called addresses (to keep historical address records) as well as a one-to-one foreign key relationship to determine which of those multiple addresses is the current active address.  Dynamic data displays the one-to-one as a drop down list in edit mode but the list is populated with every address in the table to choose from.  Is there a way to filter it so that the drop down list is populated with only the possible addresses that already belong to that person rather than every address in the table (including those that pertain to other people)?


Some basic MVC question

Web Site to Web Application Question


I've been building web sites and for my next project I will be creating a web application.  I use a 'BasePage' class in all my projects but, since web applications do not contain the 'App_Code' folder, what is the best place/practice for the 'BasePage' class?



connection string question from a newbie


when publishing  in the webmatrix dialogue it asks for "destination connection string" for my "database.mdf"

I was not sure what it was so I pasted this from my web.config file :

Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\database.mdf;Integrated Security=True;User Instance=True

it all published ok, but wont run, so I guess it has somthing to do with this connection string or some kind of configuration issue.

My question is this, What should go in the field for "Destination connection string"

Security Question Answer Retrieval


I know there is a method built in for retrieving the encrypted password, but how do I retrieve the encrypted security answer?

What I want to do is have a member profile update screen that the end user can update their password and security question and answer. However, when they get to this page, I want to already be showing the security question (the easy part) and its answer (the not so easy part).

I have updated web.config with passwordFormat=Encrypted and have added a machineKey with the generator (forgot the link, but located on eggheadcafe somewhere).

I haven't done ANYTHING yet, since I already have a user store with hashed information. I wanted to get some functionality done before publishing, wiping the store and recreating users (only a couple developers).


Very Basic Question - Error message running first page


Hi Everyone,

I am running Windows 7 and I have gone into Control Panel and activated all of the IIS Functions.

The web application I am running was downloaded from the net (and has worked on other machines previously).  Once I downloaded it, I moved it into C:/inetpub/wwwroot/code/main.asp

I am a bit of a novice at this!  But I am hoping someone can point me in the right direction!


I get the following error when I try and run the web application through IE:

"An error occurred on the server when processing the URL. Please contact the system administrator. If you are the system administrator please click here to find out more about this error."

(When i click the "click here" button it just goes to the IIS site).


Appreciate any help I can get!




C#, LINQ: (List<>) Question???


Hi Everyone,

I have a strange problem:


There is an entity (Table) called "Filters" in my .edmx which has all my tables and stuff in it (to use it for LINQ queries)

I have created a class called "CustomFilters" which inherits "Filters". So now my cutom class has all the properties of the original "Filters" class (table) and 1 more additional property that i wanted which is a List of "CustomFilters":

List<CustomFilters> children = new List<CustomFilters>();

Now i get all my records into:

List<CustomFilters> theOriginalList = new List<CustomFilters>();

NOTE: first all records are tken into a List<Filters> and then these are added into List<CustomFilters> where List<CustomFilters> for children of that record is added, and then children of the child records, and so on......

so now, every record is an instance of CustomFilters which has a property named "children" which is a list again; and each child again has instanaces of "CustomFilters", and each instance again has children...and on and on and on.....

(basiacally its a data source for a treeview in my silverlight control)

every thing is good and working as expected.


linqdatasource parameters question



I'm currently getting to know the linqdatasource control. What would happen if several WHERE parameters are added to the linqdatasource control declaritively in the aspx page but no WHERE clause is defined? 

1. is there any issue with setting up multiple WHERE parameters in the aspx markup for linqdatasource but then deciding which ones actually get used at runtime by setting the actual WHERE clause at run time? Would the unused parameters simply be ignored and cause no issues?

2. when you need to modify WHERE clause or WHERE parameters at runtime do you need to do so in an event handler? such as linqdatasource.selecting?
I see from the above link it is possible, but is that the standard way to handle controlling filtering in code behind for linqdatasource?

2b. if you use an event such as linqdatasource.selecting to add where parameters and/or modify the where clause in code will that also break the builtin sorting and paging support of the linqdatasource with a gridview?

Category attribute of user control property does not work correctly in categories tab.



I have a User Control (ascx) and a property which a want to display in my categories tab in Visual Studio in the category named "Styles".

[Category("Styles"), DefaultValue(""), Description("The value for formating something.")]
public String MyFormatProperty
set { /* the code for set */; }
get { /* the code for get */; }

And here is the problem: Actually I do not need a get, because I only have to set the property (write only property). But when I omit the get, the property is displayed in the "Misc" category in the categories tab in Visual Studio. Only when I code the get as well, then the property is displayed correctly in the "Styles" category in the categories tab in Visual Studio.

Does anybody know why? How can I display the category correctly only with set?

Thanks, S.
