Reading ConfigSections from web.config: [modified]

The obvious way is to store something in the session to say you're logged in, and to make all your pages derive from a base page that redirects to the login page if that is not set.

Hi
I am having problem with reading configSections from web.config file.
Can anyone provide a sample code, how to read this group.
Following in the web.config:

<configurations>
<configsections>
<sectiongroup name="merchants">
<sectiongroup name="merchant" type="System.Configuration.NameValueSectionHandler, System, Version=10.5.3700.0, Culture=neutral, PublicKeyToken=b77a5c561934e089, Custom=null">
</sectiongroup>
</sectiongroup>
</configsections>
<merchants>
<merchant>

<add key="name" value="shehzad" />
<add key="url" value="localhost" />
</merchant>
</merchants>

I am trying following code to read but the object a contains null value.
NameValueCollection a = (NameValueCollection)ConfigurationSettings.GetConfig("merchants");

web.config file text

<code><configuration>
<appsettings>
<add key="connection" value="User ID=11;password=111;DataBase=11111;Data Source=localhost" />
<add key="MyPractice_DataAccessLayer_Type" value="11" />
<add key="111" value="111" />
</appsettings>
<connectionstrings>
<add name="MyPracticeConnectionString" connectionstring="Data Source=RAJEEV;Initial Catalog=MyPractice;Integrated Security=True" providername="System.Data.SqlClient" /></connectionstrings></code>

to read that
in c#
using system.configuration;

string connectionsttring=configurationmaneger.appsettings["connection"].tostring();

This was not the one that I was expecting. The appsettings section can be read easily but my concern was to read ConfigSections group which we used for our customized section.

This means AJAX, or it means changing the image URL using javascript, if you know what the other image is when the page is generated.

actual problem is that
1- image crated on the imgvar.aspx
2- calling that image on registration.aspx
<asp:image id="Image1" runat="server" imageurl="~/imgvar.aspx">
3- and now if user enter the wrong signature then that image should be change . then how to refresh that image and imgvar.aspx page for new image.

well, imgvar.aspx does not exist anymore. So, you need to know what image you want to show, either on the server ( which means an AJAX call ) or have it embedded in the script if you know it, so you can just set it on the client. But, if you need to store some data so the next time the user goes to imgvar.aspx they see a different image, then you probably need the AJAX call if you don't want a postback. imgvar.aspx will need to rebuild itself to show the new image you want it to show, and it will need to do that in response to state that is stored ( probably in your database, I am guessing ), by the ajax call from registration.aspx.

Refer a capcha implementation here:

http://www.codeproject.com/KB/aspnet/CaptchaImage.aspx[^]

To refresh the image, simply have a JavaScript function which sets a blank.gif and set SRC value as a new call to aspx page with a random number to prevent caching.

Hi,

I want to open the tif files in web pages. but picture box will not support tif files. How convert tif files into gif or jpeg files programatically when i retrieve the data from database (I am storing only the path of picture files).

Christian Graus12-Feb-08 17:33

Really, you need to run a batch converter to convert them into the right format at the point of storage, not at the point of retrieval. GDI+ will load a tif, and store it as a jpg.

Thank you. I too think so. But the images have been stored already. Is there is no way to solve this problem?

Christian Graus12-Feb-08 19:36

12-Feb-08 19:36

Not really - you can write code to generate a new jpg out of the tif image, but that seems like a pain to me. Why not just run a batch converter, then do an update to your db to replace .tif with .jpg ?

In that case I have to update the database. Thank you Graus.

OK, but it doesn't relate to the presentation tier, so it's really a VB.NET or C# question. I'm only saying because asking in the right forum will get you more coverage and more answers.
