Please read if you have public ASP.NET sites

Posted By:      Posted Date: September 28, 2010    Points: 0   Category :ASP.Net
Yesterday, a new crypto oracle-type vulnerability was publicly disclosed. It is an important vulnerability that is likely to be exploitable on a large proportion of ASP.NET sites, even those that are using configuration settings that were previously considered safe. There is a workaround available already that should be set-up right now. You should pay a lot of attention to this and apply the workaround without trying to simplify it as that may result in your sites still being vulnerable. The issue is rather subtle (like pretty much all oracle attacks are). Scott published a blog post with all the details that I will not attempt to reproduce here in order to minimize any chance of confusion. Please go to Scott's post , read it and do what you...(read more)

Read Data from XML document with an special node (Multilingual Sites)



I have a question that how can I read a value of a XML line with specific nodes?

For example:

      <Item Value="Welcome" Text="Welcome to this website..." />
      <Item Value="Welcome" Text="Bienvenue sur notre site" />

How can I get "Welcome to this website..." when my site language was set to EN and my  requested value English/Item > Welcome (value)?

and how can I get "Bienvenue sur notre site" when my site language was set to FR and my  requested value French/Item > Welcome (value)?

Thank you

SharePoint Tutorial - Team Sites

Team sites are small web sites that are created to store everything about a particular thing. For example a site can be created for a department in an organization like human resources. I site can be created for a particular project. A site can even be created for a meeting. Everything about the thing (department, project, meeting) like documents, lists, calendars, etc. is stored in that site.

Creating Sites/Lists/List Items under Current User Context in SharePoint By Using SPUserToken

Usually we do this by performing the action under RunWithElevatedPrivileges method and updating the listitem using SPListItem.SystemUpdate() method (see here). but this approach has its own flaws like (RunWithElevatedPrivileges will run under system account, we cannot use SystemUpdate for SPSite,SPWeb,SPList, since it runs under system we will "CreatedBy" by as SystemAccount).

Scripts not read when in head tag


I just upgraded to VS2010 if that matters.  I'm learning JQuery and noticed that scripts don't work if they're in the head tag.  Also, I need the script tag with type="text/javascript" in the head (with nothing else) in order for the JQuery scripts in the body to work.

Very bizzare, any suggestions?

With a separate script tag in the <body> with my JQuery script, this works

<head runat="server">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" />
<script type="text/javascript">

This doesn't:

<head runat="server">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" />

Read Excel file from Web Application (C#)



I have a web app where user uploads a file.

File is saved in server locally and I want to read some data from it.

Currently my development  server has office 2003.

So do I need office 2007 in order to be able to  read an excel from office 2007 ?

What are other requirements  ?

I tried a test, using

Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.Application();
Microsoft.Office.Interop.Excel.Workbook wrkBook; // = new Microsoft.Office.Interop.Excel.Workbook();

wrkBook = excelApp.Workbooks.Open(@"C:\www\excel_files\b.xls", ....);

But When trying to open the file I get the error:

Exception from HRESULT: 0x800A03EC

So I'm wondering what I'm missing.

Public Shared function doubt????

I am using VB.net/ASP.NET and SQL Server 2000 for a web application.

For populating the dropdowns, I wrote a Public Shared function LoadDDL(), in which I pass the dataset and dropdown name to set.

I have my doubts that this function will produce unexpected results for concurrent users. And will mix the results among sessions because it is a Shared function.

I am confused here. Is it the right way to go?

Please advice. Thanks in advance.
