Hi All,
I had a task which is compare the customer age in the background and if he is 18+ then I have to show
him he is allowed for a new feature(this is typically a click link which in turn call another service) if he is under 18 then there is no display of new feature.

Client asked me to present that new feature to please the people who are eligible.

I have done all the background tasks except the presentation.
my code struck here

if(age>18)
{
///////////

}

Any suggestions????

Thanks

use some link or linkbutton or tab according to your page need and display it in only when your condition gets true.

Hello I have a gridview with this form

ID_student -------exam_mark1 ------exam_mark2-----average

to calculate the average score I used this code

double average = 0;<br />
        foreach (GridViewRow MRow in GridView1.Rows)<br />
        {<br />
            average = double.Parse(MRow.Cells[2].Text ) + double.Parse(MRow.Cells[3].Text);<br />
            average = average / 2;<br />
            MRow.Cells[4].Text = moyenne.ToString();<br />
        }

but it returns me the following error: The format of the input string is incorrect.

Help me ,thanks

the Cells collection is zero-based, so you want to average Cells(1) and Cells(2) adn put the answer in Cells(3), not 2, 3 adn 4 as you have it.

But what a horrible way of doing things...on teh sassumption that these results are pulled from a database, why not pull the average directly out of that in your select statement?

Or at least calculate the average in teh RowDataBound event....

Did you try to debug your code? Debugging if for this purpose only.

As already suggested, better to do this calcaluation and assiging in rowdatabound event.

I still have the same error.

I forgot to say that the gridview is in edit mode for columns -exam_mark1 ,-exam_mark2 and I do not know if this is the cause.

when the teacher populated the gridview he clicks insert button to insert the marks in the database and then clicks on the button average whose code is the top one.
if I use sql to calculate the average. the sql query becomes long because the pivot.if I use RowDataBound I calculate the average row by row?
thanks

Hi All,

Please help me regarding a doubt. i have a .xml file which is having around 3000 nodes, now I want to retrieve the name attribute of those nodes for which store attribute>30. Please suggest the esaiest way to do it.

Thanks,
Inder....

Load the xml with the XmlDocument and use xpath to get the nodes. Iterate those nodes the read the attribute.

Example:

<code>

            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.Load("XMLFile.xml");
            XmlNodeList selectedNodes =  xmlDoc.SelectNodes("//Store[@Stores>30]");

            foreach (XmlNode item in selectedNodes)
            {
                Console.WriteLine(item.Attributes["name"].Value);
            }

            Console.ReadLine();
</code>

My xml file:

<?xml version="1.0" encoding="utf-8" ?>
<Stores>
  <Store name="Name1" store="10"/>
  <Store name="Name2" store="20"/>
  <Store name="Name3" store="30"/>
  <Store name="Name4" store="40"/>  
</Stores>

Prevent upload of renamed and Password protected file in asp.net C#

Hi ,
We are developing a portal in asp.net (C#), where user can upload documents , We need to prevent the upload of Renamed files(the extensions changed Ex.xxxx.exe changed to xxxx.docx) , and Encrypted files(Password protected). Please advice .

Nancy

You won't be able to detect whether a file name has been changed prior to upload. As for encryption, there are copious amounts of documentation covering that subject.

One assumes you want to restrict the uploaded file types to a certian set - eg doc, docx, pdf.. whatever. So I would think it possible to examine the uploaded file/s (byte by byte) in the code-behind to at least check that its format is that of the supposed file type, according to its extension. Some research would be required to determine a reasonable test for each type, but I wouldn't have thought that that would be beyond the wit of man... or woman.

You can always manually type in the url with parameters to a browser. However, where is the request coming from? Is it from your own page? Then you need to determine why the query string is not being supplied.

yes you're right that's what i'm doing is typing the url on the address bar with the query string. and it is my page. is fiddler something that would be useful in this situation? i'm talking about trapping the request/response.

Calling multiple Page Methods in parallel

4-Oct-10 22:54

Hello All,

We have the following scenario.

1. In code behind page I have defined two Page Methods.
suppose Page Method 1 executes Add funtionality of two numbers. Page Method 2 executes Substraction functionality.

2. I want those two methods to execute at the same time in parallel. When the methods are called from JavaScript, they are called in sequential order. However, those two methods Add() and Subtract() should be called in parallel to improve the performance by getting the response quickly.

Can you please shed some light on this and help us to solve this issue.

Hi,

I have Siebel On demand web service wsdl, I want to consume Siebel OD web service in my .Net console application.
I want to update Siebel OD picklist from .Net client
I can implement this from below 2 ways.

1. Add web reference and VS will automatically create proxy class.
2. Dynamically create input soap message and pass soap message across with help web service extension’s
webrequest and webresponse methods.

Please advice which one of above process will be good in performance, scalable, lightness of invocation of web service.

Thanks,

Request.Cookies.Add Vs Response.Cookies.Add

I was just reading some article and there was an example regarding Cookies in ASP.Net. The example was using Request.Cookies.Add and I was like, Request is used to get something from client side, so this code is written incorrectly. But when I tried the code, it was a surprise for me to know that both exist and both does the same job. So I'm just wondering if someone out there knows the secret about this having Response and Request Add method for Cookies! Adios
