1. This has nothing to do with ASP.NET; please use the correct forum.
2. Please put your code between <pre> tags; use the code button above the edit window.
3. Please provide details of the error; where does it occur, and what is the exact text of the message?

Hello,
After converting MVC 4 project to MVC 5 I am getting an error "this website has redirect loop". In my web.config file I have the following:
<authentication mode="Forms">
<forms loginurl="Account/Register" timeout"2880:="">
When I try to click on any menu item, it tries to redirect to /Account/Register page. This was working fine before the conversion. How do I resolve this?
Thanks.

this code doesnt work in page which has masterpage ?
<asp:content id="Content1" contentplaceholderid="ContentMaster" runat="Server">
<script type="text/javascript">
$(document).ready(function() {
$('html,body').animate({ scrollTop: 150 }, 1000);
});</script>

Define "doesn't work". Do you get a script error in your browser's developer tools?

You're missing the point. "It doesn't work" isn't enough information for anyone to diagnose the problem. You need to describe the problem fully, including the full text of any error messages.

Thanks for all!

That's to be expected. You're using jQuery from your script block, so you need to include the jQuery script before it will work.

how can we create a database design for automated symposium/conference management system

hi,
We are trying to convert our asp.net application from targeting to .net 2.0 to .net 4.0 or 4.5. For that what we have done is we changed the application pool to run under .net 4.0 and registered aspnet_regiis from VS2010 command prompt and
set the target framework property of the application in Visual Studio IDE to point to .Net 4.0.
Now the application is not building it is showing errors in xsd, xsds designer and xsds .cs file. I don't know when .Net can convert everything from 2.0 to 4.0 why it cant handle the xsd files.
Is there any ways to convert the xsd files from .net2.0 to .net4.0 automatically, without recreating the xsd files from the scratch, because it is giving the following errors. Please help in solving the problem. Thanks in advance.
Here is the error message:
Error 7 Missing partial modifier on declaration of type 'DIS.CnpWeb.XMLFiles.Model.SurveysDataTable'; another partial declaration of this type exists C:\Abdul\ZZFDPSource\ORFdpProd\XMLFiles\SurveyBalance.cs 319 22 ORFdpProd
Thanks & Regards,

The error itself doesn't say too much. But as a shot into the dark I'd say that some class has moved into another namespace than it was on .Net 2.0.
You could try to do an incremental update and update to 3.0 first, then to 3.5 and so on, if the error has to do with the framework you can either determine at which version the change affecting you has occured, or you might even see a "Blablabla was deprecated" warning if you are lucky.

Hi, you can try changing the web.config file from target framework node from pointing to 2.0 to 4.5 and try.

1. You answered to the wrong post.
2. Your answer is useless, since the OP already tried that, and THEN his code stopped compiling.

How can we help with this information  .The Question is not clear.You mentioned some problem exist but you are not describing anything
Get the Selected value of dropdown in SelectedIndexchanged Event and display it.
To learn all there is to know. I know I'll be disappointed one day, but I've made a good start, and the eventual disappointment is likely to be brief.

Hello,
how can I calculate the percentage of the occurrences of each word in a text in c #? I would need to draw a graph using the canvasjs charts to represent the number of occurrences of data in general? Where can I find examples? Thank you.
|
|
|
|
|
Where is the problem? Define word borders? Count the total number of words? Count the occurences of a single word? Divide the occurence of a word by the total number of words and multiply with 100? ...?
|
|
|
|
|
hi..
You can use the linq to get the occurence of each word in a string like below ::
string aa = "hey how are you ? where are you going ?";
string[] a = aa.Split(' ');
var qry=from chld in a
select new { name = chld, cnt = (from r in a where r.Equals(chld) select r).Count() * (100 / a.Length) };

Ehm sorry for inconvenience.
Ehm i would calculate the percentage of values by field value. I will explain:
1) from db i'll select with c# all value from one field
var data = from db in contextDB.CERTIFICATES
where db.TYPEALGORITHM == "typeofalgorithm"
select db <== algorith is a field of my db
i made it for 4 differents algorithm ok?
well i want calculate number of each typeofalgorithm used and transform into percentage and put into pie javascript (I knowhow to do it) but i don't know how to do the percentage calculation and retrieve in
percentage to put into pie.
Thanks!!!
Very Much!
Sorry for my bad english!
