I have a button click event code block in which data should be updated to my database. After stepping through the code, the ExecuteNonQuery() executes, but no data in my database is changed. I don't think there is a problem with my code although I will include it just-in-case.

I'm confident that my command text and my parameter adding is correct.
i have in asp.net a few textboxes and i wish to update my database with the values that they encapsulate. The problem is that it doesn't work and although it doesn't work, the syntax seems correct and there are no errors present . Here is my linkbutton:
<asp:linkbutton id="clickOnSave" runat="server"
onclick="Save_Click" Text="Save Profile" />
and my update function
protected void Save_Click(object sender, EventArgs e)
{
SqlConnection con = new System.Data.SqlClient.SqlConnection();
con.ConnectionString = "DataSource=.\SQLEXPRESS;AttachDbFilename=C:\Users\alex\Documents\seeubook_db.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True";
con.Open();
String commandString = "UPDATE users SET last_name='" + Text4.Text.Trim() + "' , first_name='" + Textbox1.Text.Trim() + "' , about_me='" + Textbox5.Text.Trim() + "' , where_i_live='" + Textbox2.Text.Trim() + "' , where_i_was_born='" + Textbox3.Text.Trim() + "' , work_place='" + Textbox4.Text.Trim() + "' WHERE email='" + Session["user"] + "'";
SqlCommand sqlCmd = new SqlCommand(commandString, con);
sqlCmd.ExecuteNonQuery();
con.Close();
}
I have a local database which is updated regularly. Now I need a good way to reflect the local database changes into the remote sql server. Both the server have same database structure.
All the above pocess should work automatically from the local database server because I need to update the remote one so that the website visitor can get the updated results in the morning.I need a detailed description/ procedure to accomplish the work.
I am working on developing a .net application with c#. I have a remote DB server with sql server 2008. I have a process (exe) that writes to several tables including MSH table. I have anr sproc that updates message id in the MSH table. The update sproc is fired after the write process. When I put some break points in my code and run it through the debugger, the update srpoc always updates the record in the MSH table amd looks like everything is working fine. But when I remove the breakpoints and just run the application, I find that the records are not updated.. I run through the debugger again with breakpoints and copy the update command and parameters to test it running directly on sql server management studio query window, it works. No exceptions thrown, but update sproc does not work without the debugger with breakpoints on. Any clues what I should be looking for to troubleshoot?

I have a stored procedure which works with a temp table, and a regular sql server permanent table.en I perform an update in the stored procedure on my permanent table or temp table, the update doesnot occur? If I just manually execute the udpate code (Lines 19&20) then the update will occur. However it does not occur
in my stored procedure when I execute it from my C#. The other sql will execute but not the update?
The users of my webapplication are validated using database connection. This requires each user is a sql server database user. While logging their validity is checking by trying to create a connection using userid and password entered by the user. If connection opens successfully, it is a valid user. I also have a page in application to change the password, where sp_password is used to updated database password.
string connectionString = ConfigurationManager.AppSettings["DBServerName"];
//try to create a new connection dynamically using user id and password
connectionString = connectionString + User ID=" + userId + ";Password=" + password;
using (SqlConnection connection = new SqlConnection(connectionString))
{
connection.Open();
}
The problem is after i change password, and logout and try to login, i am able to login using old passwd also. The line of code which creates and open connection succeeds with both old and new password. If i stop and run the application again this works.
the site normally works fine in all popular browsers including firefox, chrome, safari and ie.
but doesn't work in ie 8 when it's redirected via a proxy server and it gives an error saying
"Message: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

i am adding a connection in asp.net using visual web developer to sql server database file, it's an MDF file.
when i click test connection i get this:
Only books and of course these books will be stored in an SQL server database at a romote host. So farhere are the tables I haveBooks.. of course, which describe each book that will shop up on the web site.. The site will have the ability to show all books or search books by author, catagory, etc,..Book_Catagories or properties or? This is something that the person I'm writing the web site for wants and he wants the ability to add a book to more than one catagory such as a theme book, first edition, autographed, etc,.. He wants to be able to add the catagory or catagories at the same time he enters the book..

View 2 RepliesI have a project to build a portable customer information app. Because the client works in remote locations, there is not always Internet service available, so a live online option is not feasible. I plan to construct the project with Visual Web Developer 2010 Express, with .aspx pages for data entry and use an .mdb to store data.
The client has a small server on their site. I can install SQL and copy all tables from the app into a new database. However, I'm not sure how to set up syncing between the portable copies and the onsite database. My questions are:
How do I link the portable with the onsite SQL database?
Through a script, or do I need to use Linked Servers in SQL?Would an Insert statement work? But how do I compare the two, as there may be changes on either side...?
How do I initiate the transfer?
Through a Submit button which runs the script on the user's page? Or, do I need Visual Basic or a SQL script?
I have taken over development of a asp.net 3.5, c#, MSSQL website, which I did not create.
There is a form on the website which adds all kinds of information into my SQL database. I have added two fields to the database, two corresponding extra form questions and added to the c# code behind so that these new fields are treated in exactly the same way as the existing ones.
I am therefore completely stumped as to why those two fields aren't populated in the database when I submit the form.
No page errors or anything, it's just the fields remain empty when the other pre-existing ones are populated just fine.
Is there something obvious I'm missing - for example is there a setting in the database I'm not enabling to allow the two new fields to be written to by my c# file?
I was not a programmer before this, I'm just picking it all up as I go along.
I am working on my first web site using ASP.net. In the past I was working with ADO to build Windows Forms applications.To the point...I want to know how to link my SQL db with the db that is inside in the ASP Web Site project. If I change the database using SQL Management Studio the data will be updated until I remove the .mdf of the project and add again the .mdf from my folder of SQL. I need to be able to update the database outside (Via the WebSite) and inside using SQL Server.

View 10 RepliesI have created normalised data tables to hold look up information (such as venues, players, teams etc) and want to dynamically update the 'matches' data table (my transactions) using webpages instead of running SQL queries.
What I want to do is select a name from a drop down list and then post the relevant ID associated with that name to my 'matches' table. At the moment I can only link to the value in the drop down list, i.e. the name which is incompatible with the validation which expects a primary key integer.
I'm sure this problem is a fairly common one but I haven't found the right answer on any of the tutorials or blogs, all of them assume that the data is de-normalised or describe things in more technical ways than I can yet understand. If anyone can point me to a 'how to article' or tell me what I am doing wrong, I would be grateful.
I have a system in which users can enter records into a database via ajax. Each user may hold many values in the database, with different pageId and itemId values. Each user is identified by a GUID set to a cookie. The system needs to prevent the user from entering two pieces of data with the same pageId and itemId, so I've created a script to do two database updates:
Firstly, all records are deleted from the database where the memberGUID, pageId and itemId fields match (i.e. they've already added this item).
Secondly, the record is then recreated.
It all works brilliantly, except when the GUID value is passed into the delete statement, then I just get a caught exception.
So this works:
[Code]....
But this doesn't:
[Code]....
The weird thing is that because the GUID value is being saved in the second database call, it is definitely there and is definitely the right data type etc. Even if I hard-code it into the delete procedure it still causes the whole thing to fail.
why it's failing when I add the GUID parameter in the deletion process?
i would like to update database which resides on web server from my database which is on my computer. One method is to upload the file and than make a connectionstring. But its not possible while I do so in every 10 secs.

Creating a system with web front end and SQL backend (microsoft obviously). I have tried using the asp.netsqlprovider but i can;t as i am only allowed one database on the server, so i then tried to update my current database with the triggers to input the schema into the already existing database.Next step i create my own table with two simple fields of username and password and try and authenticate that way, i can't get that to work either.
I ahve limited permissions on the network as i am a University Student. I really don't know what to do. Never had to create a log on system before and i thought it would be far simpler than this. I ahve used Microsoft's sqlprovider schema before and it worked fine. I have also authenticated via IIS and AD too before. I can't do any of those two in this instance it seems.I need an alternative for logging in users, if needs be in can be crude. I also still need to have some kind of two different views too for logged in users and not logged in users, but that can change if needs must.Don't let me down people, haha. Think this posts in the correct place, i could not find another one i thought could be more relevant.
