Check whether xp_cmdshell is disabled or not

Xp_Cmdshell

- Spawns a Windows command shell and passes in a string for execution.

The Windows process spawned by xp_cmdshell has the same security rights as the SQL Server service account.

xp_cmdshell operates synchronously. Control is not returned to the caller until the command-shell command is completed.

xp_cmdshell can be enabled and disabled by using the Policy-Based Management or by executing sp_configure

To check whether xp_cmdshell is disabled or not. Run the following Query.

SELECT CONVERT(INT, ISNULL(value, value_in_use)) AS config_value

FROM  sys.configurations

WHERE  name = 'xp_cmdshell' ;

To enable the xp_cmdshell, you can refer the following msdn doc.

JQuery InnerFade Issue

I have recently used the Jquery plugin "Innerfade",  to fade in and out any element included in the container.

Reference : http://medienfreunde.com/lab/innerfade/

Its very easy and so simple. But, one issue that really bugged me is that, if i left my browser open for awhile, then all the images with in the container will start fading fast on top of the another image. 

I found the bug fix for this. If you experiencing the same issue using innerfade plugin. You can modify the "jquery.innderfade.js" script line 93 and 96 as i did. It fixed the issue.

line 93...$(elements[last]).stop(true,true).slideUp(settings.speed);
line 96...$(elements[last]).stop(true,true).fadeOut(settings.speed);

PHP and C#.Net MD5 code mismatch

Are you experiencing the MD5 code mismatch, even though you are using the same string and key in Php and dot net? Of course it does... Since we need to convert the string + key into ASCII bites. You can use the below code in C#.Net to match the MD5 code in php.

               var strKey = "********";

               var strValue = "abcd";

                byte[] asciiBytes = ASCIIEncoding.ASCII.GetBytes(strValue  + strKey);

                byte[] hashedBytes = MD5CryptoServiceProvider.Create().ComputeHash(asciiBytes);

                string hashedString = BitConverter.ToString(hashedBytes).Replace("-", "").ToLower();
