Microsoft JScript runtime error: ASP.NET Ajax client-side framework failed to load

You suddenly might end up getting above message when trying to run your ASP.NET project. There various solutions given in forums and only after changing the web config as follows worked for me!

  <httpHandlers> 

 <remove verb="*" path="*.asmx"/>
 <add verb="*" path="*.asmx"  

validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
 <add verb="*" path="*_AppService.axd"  

validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
 <add verb="GET,HEAD" path="ScriptResource.axd"  

validate="false" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

send mms from sql server (only within Sri Lanka)

Most of us know that we  can send MMS messages  using gmail. For the sake of completion I ll list down the basic steps to achieve it.

1)  Compose a new mail. In the to box type your mobile number (i.e. 009477xxxxxxx@mms.dialog.lk for Dialog, 009471xxxxxxx@mms.mobitel.lk for Mobitel). I haven't tried this with the other service providers. 

2) Type in you message and send it as you are sending a normal email.

I have taken this to a one more step further by using this concept to send mms messages from SQL Server dbmail. Follow these steps

1) Create a mail profile for your gmail account using Database Mail wizard. Specify your maill account setting as follows.

2) Call the created profile inside your stored procedure ass follows.

EXEC msdb.dbo.sp_send_dbmail
    @profile_name = 'sendmail',
    @recipients = '009477xxxxxxx@mms.dialog.lk',
    @body = 'Congrats for sending first MMS..!!.',
    @subject = 'Test MMS' ;

It will take some time to deliver sms  to the recipient. Please note that the recipients phone must support MMS for reading this message.  You can use this method to send a simple SMS without being bothered about buying a SMS gateway. 



Note: If you receive the "gmail smtp error 5.7.0" message when sending mail, try changing SMTP from smtp.gmail.com to smtp.googlemail.com

asp.net Menu flickering

When you are using a asp.net menu when any postback occurs and the page gets rendered again the menu "flickers" for a moment. When this happens the whole menu items will be displayed for some time.

As following post suggests setting display:none in #menu ul li ul solved the menu flicker issue for me .

Edit
If the above solution  doesn't work try setting the RenderingMode ="Table"  in the Menu .

select item;

2)
