I need to change a user's role in my application. Therefore I need to know the correct syntax in code behind to alter a user's role; i.e. string sql = "ALTER TABLE ...etc". I'm not sure how to implement this at all. Is it similar to the INSERT INTO query used in code behind, where we define the parameters etc?

how do i write my alter schema query in Asp.net
using the sqlclient object..
I have a table that contains image data type and has more than 20,000 records.I want to change its file group to the new file group. I tried to change it using table designer, but everytime I wanted to save it, it occured an error with this message:
[Code]....
Does anyone know how to change file group using Alter Table query? I'm using SQL Server 2005.
I am using the ASP.NET membership system and I have found the ability to 'add user to role' programtically, but I am wondering if there is a way of changing a user role?
I don't simply want to add a user to another role and I can't seem to find the 'remove user from role' command.
I am using forms authentication and authorization through roleManager. I have two Roles - "Customers" and "Employees". The redirection to the default page for the "Customers" role is working fine, but I get an oledb error stating that one or more parameters are not being passed when I redirect a user from the "Employees" role. The following is the code in login.aspx that handles the authentication of the user:
If myReader.Read() Then ' We have a match
If myReader(1) Then ' This is true if an Employee and false otherwise
If Not Roles.IsUserInRole(logInUser.UserName, "Employees") Then
Roles.AddUserToRole(logInUser.UserName, "Employees")
End If
ElseIf Not Roles.IsUserInRole(logInUser.UserName, "Customers") Then
Roles.AddUserToRole(logInUser.UserName, "Customers")
End If
FormsAuthentication.RedirectFromLoginPage(logInUser.UserName, logInUser.RememberMeSet)
Else
Response.Write("Invalid credentials")
End If............................................
Here I have specified a query which gives an idea about how to drop a constraint and recrate it..

Parent_TableName: is the name of the table where we actually reffer.
I have the following code that I wasnt to alter the Dataset before it is bound to the dropdown list.

What I would like to do is ALTER the dataset for the Parent (dropdown list - ddlRT). I need to format and disable certain topics. I have a script I create before I added the datarelations.
Im using two stored procedures to write and update values in a SQL DB. Im using the SQLDatasource update method. When I run the webpage on my development server everything runs fine. When I try and run the web page on my Live server I get the following error :System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding This always takes 30 seconds to fail - and looking at google it seems that this is a connection timeout error.In my web.config file I have updated the connectionstring line to include a timeout setting :
connectionString="Data Source=myserver;Initial Catalog=ReportServer;Integrated Security=True;Connect
Timeout=10000"
But this hasn't helped at all.
I am using SQL SERVER 2008 database. I have a table Customers in which the CustomerID column is had datatype INT intially but due to increase in Customers the number range is exceeding which may cause error arithmetic overflow of data. Hence I thought to modify the datatype from INT to BIGINT and wrote an alter script but when I ran the script it failed. Hence provide me in creating alter script for the updating the datatype of the primarykey column for the Customers table.

I'm not getting any error messages but when I view the web page in the browser, it is stuck in a continuous loop where the page displays (correctly), then posts back to the server and displays again.
1. I have a GridView on my page and it uses sqldatasource with parameterized query. What I want to do is, on page load (where nothing has been selected so no parameter supplied), I want it to query everything (something like SELECT * FROM [this_table]) but since my SelectCommand is something like
SELECT * FROM [this_table] WHERE [this_column] = @someParameters AND [that_column] = @someParameters.
Can I play around with default value to achieve something like that but how ? Now, when the page loads, it doesn't show anything (No Gridview).
2. On my page, I made something like (username, gender, address, and more) and one single search button. That means, no single control enable auto postback. What I am trying to accomplish is building dynamic query
(if username specifed -> SELECT * FROM [this_table] WHERE [username] LIKE @username).
If both username and gender are specified (SELECT * FROM [this_table] WHERE [username] LIKE @username AND [gender] = @gender) and you know the rest. How can I do this using GridView and SqlDataSource ? To my knowledge, I can only specify one SELECT statement in a sqldatasource.

This query works perfectly on the query analyser.
But when configuring the Table adapter ,I try executing the query and i get 0 rows affected.
What could I be getting wrong in this case.
NB:Existing GalleryID has been supplied.
By right clicking on my database i created a query in server explorer. But where are this query stored can't find them back. I should aspect that their is a folder query's like there is a folder tables but this isn't the case.

View 5 RepliesI've got a query such as
Dim MediaQuery =
From m
In dB.DOWNLOADS _Where m.ID = id _Select
which returns a record from the database. One of the fields in the record is a FK to another table. I need to read this value to be able to set a dropdown based on the ID but I can't work out how to access it. For a standard record I can just do the following txtTitle.Text = MediaQuery.FirstOrDefault().TITLE
However with the foreign key it doesn't work like that. I've tried drpGroup.SelectedIndex = MediaQuery.FirstOrDefault().DOWNLOAD_GROUPS.ID where DOWNLOAD_GROUPS is the FK field but it returns Object reference not set to an instance of an object. If you're simply wanting to read some values from a single db record in the entitiy framework and one is a foreign key how should I go about getting the value?
I have a listbox (UsersListBox) which shows all the users and a gridview (gvRoles) which shows the users' roles when their username is selected in UserListBox. gvRoles is below. When I click the buttonfield in gvRoles, I'd like for my OnRowDatabound event to call up the gvRoles_RowDatabound method. I'm trying to get this method to remove the username selected in UserListBox from the role in the row clicked. How do I go about that using the roles and membership classes?

I'm trying to allow logged user who are in department XYZ to perform some task for my third party App. I have two SQL tables named Users & UserList. The third party app (GoldMine) graps the USERNAME from the Users table and store it as UserID which I then referecnce SessionID. The UserList table has two columns (GM_UserName & Department) which I'm interested in. When a user login into the 3rd party app (GoldMine), i then compare the USERNAME (from Users table) to GM_UserName (from UserList table) and see whether GM_UserName is in = 'Dept XYZ'. Take a look at the SQL query below.
sqlDept = "SELECT USERNAME FROM Users LEFT JOIN UserList ON UserList.GM_UserName=Users.UserName WHERE UserList.Department ='Dept XYZ'"
I'm able to do this.
If Session("Userid") = "TestUser1" Or Session("UserID") = "TestUser2" Then Do this Else Do that End If
BUT unable to do this...
If user's Department = 'Department XYZ' Then
Do This
Else
Do that
End IF
I want to display a menu (which will be strongly typed with it's own unique model) across all pages only if a user is logged in.What menu items are available depend on the user's role and also I'll need to hit the repository to get numbers like "x Messages", etc
Been scratching my head for a simple solution here. Don't want to create something that need changes all over the place.All my controllers derive from a BaseController, all my Models from BaseViewModel....probably where I'll be implementing functionality for this.
I have created a webpage using wizards to set up the objects, can I change the name of all the datasources by just going into the code and entering the new database (the tables are identical) ?ORDo I have to work my way back through all the wizards and re-enter parameters?
View 3 RepliesI have a datatable that looks as follows:
Make,Ford,0
Model,Fusion,0
Year,2010,0
Make,Ford,1
Model,Focus,1
Year,2010,1
I'd like to loop through each row and replace all the values of the same type in the 3rd column with a different value.
So for example I would change all the 0 to 1234 and all the 1 to 1235. So I'd end up with:
Make,Ford,1234
Model,Fusion,1234
Year,2010,1234
Make,Ford,1235
Model,Focus,1235
Year,2010,1235
Whats the best way to do that ?
I want to implement access control for usercontrols depending on user role(s), I want to do it on the control base class, in such way that on every user control I only need to set a string with allowed roles to see the user control
This is how an user control class may look like:
public partial class SimpleMenu : MyUsrControlBase
{
protected void Page_Load(object sender, EventArgs e)[code]...
How to set up user control visibility from the base class depending on the validation result?Also which event in the user control is the best to set the roles?
AlloweRoles = "RoleA, RoleB"
When I create a new login for my SQL Server 2008 I also specify a password for this login. But when I, after the creation is done, check the login's properties the password is much longer than the one I specified. If I here change the password once again, SQL Server 2008 will automatically change the password for the login - again. ANd I don't know what the password that SQL Server keep putting for my logins, since the password consists of small black dots.
View 4 RepliesHow can I change the parameter value from Interger to String.
Here below is the part of the code that creates problem; the constant "sqlStatement" is as string, but when the parameters "@ProdColor" read the value it returns an integer instead of the proper type which is a string. I have tried every ting like: CType(sqlStatement(splitItems(1)), string)
Or convert or parse, but it keeps returning the wrong type.
Const sqlStatement As String = "INSERT INTO ProductDetails (ProdID,ProdColor,ProdSize) VALUES"
If item.Contains(",") Then
splitItems = item.Split(",".ToCharArray)
cmd.Parameters.AddWithValue("@ProdID", SqlDBType.Int).Value = sqlStatement(splitItems(0))
cmd.Parameters.AddWithValue("@ProdColor", SqlDBType.NVarchar).Value = sqlStatement(splitItems(1))
cmd.Parameters.AddWithValue("@ProdSize", SqlDBType.NVarchar).Value = sqlStatement(splitItems(2))
