Microsoft JScript runtime error: 'Sys' is undefined

This error we can solve by adding some code in webconfig file ... code is bellow

XML

<httpHandlers>
      <remove verb="*" path="*.asmx"/>
      <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
      <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
      <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false"/>
    </httpHandlers>
    <httpModules>
      <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
    </httpModules>

place this code in <system.web>

This does not work, anyway this code is already added when solution/projects are created.

Did you try Google - http://www.google.com/search?q=Microsoft+JScript+runtime+error%3A+%27Sys%27+is+undefined&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a[^]

It isn't that hard my friend and is said to be the programmer's best friend. The sooner you learn using it, the better for you.

Happy Coding!

Good Link

thank you now my code is working

Ankur^\m/ 6-Apr-11 0:30am

Most welcome! I am glad that you got it working.
I would also request you to add an answer here explaining how you solved it. You may also refer to the links which gave you the solution.
Thank you!

hows it working sathishreddyA Saab ?, is it fashion applauding all-n-around your near, jst for makin some points ?

Ankur^\m/ 14-Sep-12 7:50am

The way I see is you are creating multiple comments "just to make some points". Did you go over the link and read the discussions? :doh:

sathishreddy A 6-Apr-11 0:51am

ya sure

guru.talk 14-Sep-12 2:46am

Dear, Im having same issue, but wht that link, does do except opening same link. And Dalek Dave G , u r saying good , for what !

Ankur^\m/ 14-Sep-12 7:49am

The link gives a millions of pages which discuss the same issue. There is no point wasting your time answering the same question. Googling and reading the discussion about a problem would save you a lot more time than typing it here and waiting for someone to respond. If you are not able to find a solution even after reading those discussions, it then makes sense to come here and ask the question providing details of what you tried.
Hope you understand now guru talk G!

Solution 2 solved my problem. Sigh, nice to see when asking for help people just direct you to google searches.

Ankur^\m/ 2-Oct-12 12:33pm

That's because you will save your's and people's time by doing that. Why rediscover the wheel? Just a search and you have a list of discussions from all those people who have been through this.

MCPD-Guy 3-Oct-12 9:39am

I undestand what you are saying but instead of reading one forum/post from CodeProject, you now have to go through all those searches to find the correct solution. It would be a different story if you posted a single link to a solution. Google is a developers best friend!!

Ankur^\m/ 4-Oct-12 1:47am

Well believe me that's not really the case these days. Google does amazing work in sorting the results for you. It would be top 2-3 links mostly where you will have your answer. Also there are times when a problem could have multiple solutions. Unless you read at least 2-3 discussions you may not find a solution that suits you.
Certainly Google is developer's best friend!
