Problem
Adding constraints such as check constraints or foreign keys to a table are best practices to keep your data as clean as possible with minimal data enforcement rules performed at the database level. Unfortunately sometimes issues may occur where the data becomes out of synch and one of these constraints has been violated. This may be due to disabled constraints or constraints that are later added with the NOCHECK option. Finding these issues can be done by running queries to check each of the constraints, but is there any easier way to determine if the data the constraints support has been violated?
Solution
As mentioned already, one approach would be to write queries for each of the constraints and check the data to see if the constraints are being enforced. This is probably not all that difficult, but it could be time consuming. Another approach to tackle this issue is to use the DBCC CHECKCONSTRAINTS command. This command allows you to check the constraints to ensure that no data is violating the constraints that have been setup.
This command can be run as follows:
DBCC CHECKCONSTRAINTS (TableName) - checks an individual table
DBCC CHECKCONSTRAINTS (ConstraintName) - checks an individual constraint
DBCC CHECKCONSTRAINTS WITH ALL_CONSTRAINTS - checks all constraints in the database
DBCC CHECKCONSTRAINTS WITH ALL_ERRORMSGS - returns all rows that violate constraints
DBCC CHECKCONSTRAINTS WITH NO_INFOMSGS - suppress messages when query runs

This is a SQL Script that Cleans your Database Records & resets Identity Columns, and it is all in 6 lines!
/*Disable Constraints & Triggers*/
exec sp_MSforeachtable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL'
exec sp_MSforeachtable 'ALTER TABLE ? DISABLE TRIGGER ALL'
/*Perform delete operation on all table for cleanup*/
exec sp_MSforeachtable 'DELETE ?'
/*Enable Constraints & Triggers again*/
exec sp_MSforeachtable 'ALTER TABLE ? CHECK CONSTRAINT ALL'
exec sp_MSforeachtable 'ALTER TABLE ? ENABLE TRIGGER ALL'
/*Reset Identity on tables with identity column*/
exec sp_MSforeachtable 'IF OBJECTPROPERTY(OBJECT_ID(''?''), ''TableHasIdentity'') = 1 BEGIN DBCC CHECKIDENT (''?'',RESEED,0) END'

right click on your chrome icon then select properties. Under the shortcut tab you will see Target. The line ends with chrome.exe so just add –in-process-plugins after that. So the line should look something like this:
C:\Users\user\AppData\Local\Google\Chrome\Application\chrome.exe --in-process-plugins

How to use LogMeIn Free with Windows 7 Beta/RC:
1. Download the LogMeIn software to your desktop from this site: https://secure.logmein.com/logmein.zip
2. Unzip the folder to a new folder on your desktop named “logmein”.
3. Go to the start menu and search for “cmd. When you find the Command Prompt entry, right click it and select “Run as Administrator”, and Click through the warning prompt.
4.In command prompt type “cd\users\\desktop\logmein\x86” without quotes and press enter. (If you are running 64-bit Windows change the ‘x86′ to ‘x64′)
5. In command prompt type “logmein install” without quotes and press enter.
6. The installer will run and you should then see the tray icon when it’s finished. Right click on the icon and select “Open LogMeIn…”
7. Firefox will open and you’ll get an error box. Just click “OK“.
8. Copy and paste this address into the address bar: https://127.0.0.1:2002/
9. Click through if you get a popup warning you about a certificate. On the page itself you will see something to allow an exception. Click on that and then click ‘Get Certificate‘ in the next box. Again you will probably get another warning but just click add anyway.
10. You should see the familiar LogMeIn screen. Just put in your computer user credentials and then you will be asked for your LogMeIn credentials.
It is a pretty straightforward process, but does take a bit of workaround to get it setup. Hopefully over the next few months LogMeIn will add support to Windows 7 for its installer package.
You ll be suprised when entering as you used to your username and password worked ok.
In Windows 7 if you use it this way u ll get this error message:
Error: Logon failure: unknown user name or bad password. (1326)
REMEMBER to type the username like this
computername\username
password
