LINQ to SQL - Validating if item is in Database, but if item is not items not inserting into databas



I am new to this, so bear with me.  I am writing an application in C# that uses LINQ to validate a datacontext off a textbox to see if the record exists already.  If the record does exist I inserted an if statement to advise the user that the record exists, if the record does not exist I would like to allow the record to be added to the database.  If I take out my else statement everything works fine as far as inserting goes, but I do not want to allow inserts in this scenario.  I have tried moving the if and else statement to different parts of the code but can't quite figure this one out.  Any help would be apprecaited, attached is the code.  This code is set to a button press.  As a matter of fact, if you see any other errors along the way please feel free to point them out. 



    protected void enterBTN_Click(object sender, EventArgs e)
        //make new data context

        SHCDataContext insNewAll = new SHCDataContext();
        //LINQ to check if customer exists in database
        var checkExisting = from c in insNewAll.Customers
                            where c.custLastName.Contains(custLastNameTB.Text.ToString())
                            select c.custLastName;
        //make list to store values

How to reflecting database changes immediately on asp.net page


Hi Everyone.

I have a web site that is highly dependant on a SQL Server 2008 database.  I am using linq to sql to connect to the database and require the website to reflect database changes immediately.  Currently the changes are only reflected once a postback occurs and the database is requeried.

Is there a way to get the asp.net page(s) to be alerted of an database change and then to reflect it immediately, or within seconds, on the display?  I am aware that one can use the SQLDependency class and ADO.NET to do this, but am not aware of any linq to sql possibilities.

Any help will be greatly appreciated.

Visual Studio 2010 Shows Blank Page during web development


I just upgraded a web project from VS2008 to VS2010 Ultimate (Windows7 64bit, IE8/Google Chrome. When I run the web project in the development server (by hitting F5) everything acts like it is supposed to except everything comes up blank. Even the directory structure page is blank, just an empty HTML open and close shell. I get no errors no indications of failure, nothing. When I try to use google chrome I get the same blank page no matter where I navigate to, even if I try to navigate to a non-existant location on the dev server. I know the code compiles and acts correctly because I can deploy it to our QA servers without issue. Any ideas? 

Database login set up issue

Hi folks, I have more than one domains trusted each other, one user has already been granted access in the server, but I don't see it using Exec  xp_logininfo. I even tried adding the user as sysadmin. no problem for most of other users from the same domain. For another user, when I run the Exec  xp_logininfo, it returns: Msg 15404, Level 16, State 11, Procedure xp_logininfo, Line 62 Could not obtain information about Windows NT group/user 'INTL\RTxie', error code 0x534. what happened to these two accounts? is it a SQL issue or Active Directory issue? That domain has 15000 accounts across over 100 domain controllers. my domain has roughly the same amount users. they are trusted each other under same forest. Thank you in advance.

Unable to install SP3 on SQL 2005 due to Database Services language being blank

Hi all,   I have an issue that requires me to upgrade to a later SP (currently on RTM), but when I try to install SP3 Database Services cannot be ticked. Upon inspection I see that its reporting "This update requires language ENU.  The language for this product instance MSSQLSERVER is . Download the upadte for langage .", when I check teh Language field to the right it is blank, other parts however are fine and can be upgraded. Can you advise please as I don't know how to manually set the language (which is reported inside SQL itself as English (United Kingdom)) and I cannot un/reinstall. Thanks, John

Single-page restore/recover in an online database

I am working with SQL Server 2008 64-bit (10.0.2531) on Windows Server Datacenter 2008 SP2 (64-bit). The problems I am having almost certainly stem from my lack of understanding of how SQL Server's transaction log is handled during recoveries. I am using this document as a rough guide. Here' what I am doing: 1. I intentionally corrupt a single data page in a normal table, so that I can practice single-page recovery. 2. I attempt to read the corrupt block in SQL. As expected I receive an error. 1> select top 10 firstname from ds2.dbo.customers 2> go Msg 824, Level 24, State 2, Server IP-0AF647E0, Line 1 SQL Server detected a logical consistency-based I/O error: incorrect pageid (expected 4:896; actual 3:0). It occurred during a read of page (4:896) in database ID 5 at offset 0x00000000700000 in file 'C:\sql\dbfiles\cust1.ndf'. Additional messages in the SQL Server error log or system event log may provide more detail. 3. I take a log tail backup before I do anything to try to fix the corruption: 1> backup log ds2 to disk = 'c:\sqlbackup\ds2.bak' with norecovery 2> go Processed 5 pages for database 'ds2', file 'ds_log' on file 1. BACKUP LOG successfully processed 5 pages in 0.041 seconds (0.857 MB/sec). 4. I  restore the corrupt page from backup: 1> restore database ds2 page='4:896' 2> from disk='c:\sqlbackup\ds2.bak' 3> with norecovery 4&

Master Page css linking issue

I'm having an issue with my css file linking to one of my nested master page.This is the general setup of my site:Root-RootMaster.master--Dir1---Dir1Master.master---Dir1Style.css--Dir2---SubDirA----Dir2Master.master----Dir2Style.cssI have a content place holder in the <head> of the RootMaster.master so that I can specify a css file for each nested master page.  I have Dir2Style.css linked in Dir2Master.master, and it works both in the designer and on the site for all content pages.  It's linked like so:<link href="Dir2Style.css" rel="Stylesheet" type="text/css" />However when I link Dir1Style.css to Dir1Master.master, it is only linking correctly in Visual Studio.  Whenever I open a content page in that directory using that master it doesn't apply the css.  I've also tried dragging and dropping the css file onto the page so that it sets up the path itself, and it still won't work.  The only way I've been able to get it to show correctly on the site is by doing a <% ResolveUrl() %> for the href, but then it doesn't work in the designer.  Any ideas on why it's working for one and not the other?  Both the nested master pages are set up the exact same except for the css link...

SSIS And Sybase Source OLEDB connectivity issue with code page for character set
