For some reason, some of the fields in our database use a different collation than the default. There doesn't seem to be a pattern as to which fields use the different collations, so I'd like to run a query to find which fields use this collation and change them to the default. Does anyone know how to do this?
View 2 RepliesI seem to be getting the following error when trying to do an inner join on a new table I have recently created. The only way I have got around this so far is to put "COLLATE SQL_Latin1_General_CP1_CI_AS" into my join. Cannot resolve the collation conflict between "SQL_Latin1_General_CP1_CI_AS" and "SQL_Latin1_General_CP1_CS_AS" in the equal to operation.
I have not seen this error previously when doing joins, and it is a real pain. My only thoughts are that I have recently added the ASP.NET Security tables to my database - could this be causing the issue? Is there a conflict with collation going on? Although all my tables seem to be using the same Collation as the "aspnet" tables when I look at the extended properties of each table.
I'm creating a site that will offer several different services (blogs, videos, images..), all under the same site.
Each service will use a separate database and all services must use the same membeship info. Users will only need one login to access all these services.
For the membership database i will use the default aspnetdb database.
There are two ways i can think of:
1) Use a join-query between two databases, each time i want to show some service records per user.
2) Create a custom membership-info table in each service's database, and keep it in sync with the master membership table in aspnetdb database.
The custom membership table will be like this:
Id - int, primary, identity
UserId - uniqueidentifier (of aspnetdb database)
What is the best way to do this in the long run, when i will have six or seven or more services ?
I have 2 Linq to Entity queries, here they are:
[Code]....
In "query" there are several columns, 2 of them are NIIN and Qty. In "objViewDDRT" there are only 2 columns, they are NIIN and AvailBalance.
What I need to do is for each row in "query" check to see if the NIIN is in "objViewDDRT", and if it is get the AvailBalance for that NIIN from objViewDDRT.
I was put in charge of a database that has no source control, and all work was done in the database. I want to pull all the objects (stored procs, views, tables) from the database, and add to my new source control.
Is there a way to get all the objects into individual files out of a database?
Our database is SQL 2005. I have Visual Studio 2005/2008/2010 (beta 2) at my disposal.

View 1 RepliesI have a gridview control that displays expenses claims received from clients. I have a template field that contains a checkbox - if this is ticked, a value from the gridview is added to a variable and this is outputted to a label control.
What I then want to do is to update the database according to which row has been ticked. I have so far the following code that adds each value to an array, which I was then hoping to access in the sql query i.e. Update table set value = value where id = (id's added to array)..
Code as follows - so far I'm just displaying the count of values in the array to make sure they are actually being added:

This seems a little clunky, as in slow. Is there a better way to get the Class B (User) information without making a query every time?
im developing a silverlight project using silverlight 3, vs2008 and linq2sql. when projects starts, im storing all the data from database into some static list variables. so when ever i need data, im reading it from those static list variables. all i want to know is, is it good to store data in static list variables and use it when ever necessary or is it good to get data directly from DataClassesDataContext object like db.mytable. which is the rite and fastest way or retrieving data. i mean which will use less connections to database?

have some Objects, lets say Employee and Role defined as below and I have defined relationships in my database that gives me a list of objects say employees and thanks to my framework each employee object also has a Role object linked via the RoleIDID, UserName, Password, Email, RoleIDRoleID, RoleNameSo in code I can do something like this
Employee emp = dataService_GetEmployeeByID(1);
string RoleName = emp.Role.RoleName;
Now here is my problemI can bind any object in a repeater and it works fine for the first level in my relationship
For instance <%# Eval("UserName") %>
But I need to be able to show the details for my child objects as well (Role) so something like this (which does not work)
<%# Eval("Role.RoleName") %>
I am working on a website where the content has to be displayed in English, Polish, Slovak and Czech. Currently, everytime a special character used in the non-english languages (such as Á or â), it displays as just a normal A or a. I've traced the problem down to the database. Currently the collation is "Latin1_General_CI_AS", and when the special foreign characters are put on to the server, the server saves it as a normal standard english character.
I've looked at several answers, but most seem to change the database collation within the SQL query, and this is something that isn't feasible for me to do (due to the size of the site). What I'm trying to do is find a collation for the database that will allow the foreign characters to be saved as well as the english characters (a bit like how UTF-8 works in HTML).
I know how to bind a simple objects to a dropdown list. However I am having problems binding my objects which contains sub objects to the control.i.e. with simple object i just do ddl.DataValueField = "myproperty"
with my objects they contains sub objects which i want to bind. I have tried ddl.DataValueField = "sub-object.myproperty" which doesnt work.
I need to get values of all individual cells from the row of a grid view and assign eac one fo them to seperate variables. Should i just access the control values directly from the gridview (the controls are template fields) or is it best to run an sqlq select query for each value i want to retrieve.

I have a gridview with a column of text boxes bound to a value from a database.

View 5 RepliesI'm building an ASP.NET MVC 2 site where I'm currently implementing an OpenID sign-up form. Unfortunately, I'm foreseeing a possible security bug/vulnerability inside my architecture.
Here's how I want OpenID login to work:
User requests /Account/Login, Controller sends back OpenIDLogin View. User enters their OpenID into the View, then OpenID authorization takes place, and finally the OpenID is returned to the Controller.The Controller checks whether the OpenID is currently in use by a user in the system or not. If it is, the user is logged in to that account. If not, the registration process begins.
And now, the OpenID registration process:
The OpenID identifier, as well as any other information provided by the OpenID provider (such as email address or name), is put into my custom ViewModel and sent to my OpenIDRegistrationForm View.The RegistrationForm View stores the OpenID in a hidden field to make sure that it gets sent back to the Controller.The user fills in the RegistrationForm View and sends it back to the Controller.The Controller creates the user account and puts the OpenID into the database.
The bug that I see within my architecture is that a user could modify the hidden value in the RegistrationForm View. Thus, they could spoof their OpenID! I will make sure to add another round of checking to the final Registration Controller Action to make sure that the OpenID that is provided doesn't exist yet, but there is still a possibility for spoofing. Can my architecture be improved somehow? I don't want this to end badly...
One solution I'm considering is encrypting the OpenID before I send it to the View and then decrypting it when it reaches the Controller. Should I try this?
so I am new to ASP and I am confused here about how to obtain specific data from a specific cell.so, i have a gridview that i fill from a SQL source, this works fine. what i have been task to do is add an editable text box and a comments portion to the site. these controls are to be inside the gridview. my dilema is getting the primary key of the row i am inside of.
Example when i click in the text box i created and i change the text the "ontextchanged" event fires; however, i am having difficultly at that point getting the primary key from column [0] of that specific row. i need this so that i can update the database.here is some of my code

firstly a static class only ever exists once and is not an instance. Any static members (ie static int NoOfPeople;) is stored in one place and is shared between all sessions (like the old global variables).
Now static methods is where i'm not 100% sure. If I have a static method that doesn't use any other static members could this cause inconstant results, example (this is a fairly pointless method but just a quick example of the top of my head)
[Code]....
So in this example if two sessions (or threads) were to call this at the same time - would they both get back the expected results, because the method only uses private data (a, b and totalToReturn).Im sure this sounds a little simple but I will be using static methods to build user objects and various other objects that there will have to be a 100% garentee that the objects will not get mixed up between sessions and the wrong things return to the user.
I have certain information in my webconfig such as the name of the database i am connecting to. However, I would like a situation where my aspx is able to obtain that information as well and display it in a label. Hence, how do I go about doing that.
View 3 RepliesI wish to obtain the domain SID from a user account that has been used to access my web page, but...
In some instances, you dont have access to the HttpContext object to call HttpContext.Current.Request.LogonUserIdentity.User.Value
All the static function is able to accept is a user-name as a string, and a domain-name as a string.
If the domain is left blank, it is amused that the user account name is within the same domain as the IIS server that the process is executing upon. :/
