I had faced this issue when i upgraded my VS2008 RDLC reports in VS2010 to adopt 2010 Schema (another night mare :)). I was using a local reprot to render in PDF format in my web apps and it consumes certein paramters to show in header, footer and also used in some of the expressions.
Unfortunately, all my textboxes that used this paramter value displayed "#Error". I had spent almost around 3 hours on this and later realized the cause. This is due to some CAS (Code Access Security) recently implemented in .net 4.0 framework. We need to give additional permission to evaluate the expression in RDLC report. Details are mentioned here in the blog nicely.
Here is the sample code of mine. The object "report" represents local report object (LocalReport report = new LocalReport();)
ReportParameter[] parameters = new ReportParameter[4];
ReportParameter p2 = new ReportParameter("datetime_format", SessionContext.CurrentSessionDateTimeFormat);
ReportParameter p3 = new ReportParameter("date_format", SessionContext.CurrentSessionDateFormat);
ReportParameter p4 = new ReportParameter("currency", "All transactions are in " + SessionContext.CurrencyCode);
//
parameters[0] = new ReportParameter("request_no", requestNo);
parameters[1] = new ReportParameter("datetime_format", SessionContext.CurrentSessionDateTimeFormat);
parameters[2] = new ReportParameter("date_format", SessionContext.CurrentSessionDateFormat);
parameters[3] = new ReportParameter("currency", "All transactions are in " + SessionContext.CurrencyCode);
//
report.SetBasePermissionsForSandboxAppDomain(AppDomain.CurrentDomain.PermissionSet.Copy());
// Added above line to grant additional permission to execute the expression assembly
//
report.SetParameters(parameters);
Cheers...
Note: The above fix is required for the expressions/formulas to work properly in the new version.

Failed to decrypt the Web.config in asp.net
After encrypting the appSettings in web.config file using the command
aspnet_regiis -pef "appSettings" "c:\<appfolder>"
you may recieve the following error
"Failed to decrypt using provider 'RsaProtectedConfigurationProvider'. Error message from the provider: The RSA key container could not be opened."
or the site will not work since it cannot read/decrypt the web.config contents (connection string or any similiar data).
Resolution
This is because your ASP.NET application identity does not have access to the .NET Framework configuration key store. To give rights use the following command
aspnet_regiis -pa "NetFrameworkConfigurationKey" "<application pool identity account>"
Hope this helps..

Millions effected with windows worm - Conficker, Kido or Downadup
The worm Conficker was discovered in October 2008. Anti-virus firm F-Secure estimates there are now 8.9m machines infected.
According to Microsoft, the worm works by searching for a Windows executable file called "services.exe" and then becomes part of that code. It then copies itself into the Windows system folder as a random file of a type known as a "dll". It gives itself a 5-8 character name, such as piftoc.dll, and then modifies the Registry, which lists key Windows settings, to run the infected dll file as a service.
Once the worm is up and running, it creates an HTTP server, resets a machine's System Restore point (making it far harder to recover the infected system) and then downloads files from the hacker's web site.
Anti-virus firm F-Secure says that the worm uses a complicated algorithm to generate hundreds of different domain names every day, such as mphtfrxs.net, imctaef.cc, and hcweu.org. Only one of these will actually be the site used to download the hackers' files. On the face of it, tracing this one site is almost impossible.
Once the worm is running on the computer, it makes it very hard for users to restore their machine to a safe point before their operating system was infected, and automatically starts to download more malicious programs, that further compromise the PC, from hackers’ websites.
It’s using multiple replication mechanisms, including USB sticks, so if someone got an infection from one company and then takes his USB stick to another firm, it could infect that network too.
Computers users are advised to ensure their anti-virus software, operating system and firewall is up to date, and that they have installed a Microsoft patch designed to combat the problem, MS08-067, which is available from the Microsoft site.

Get GridViewRow in button click event in GridView control
When we use template field columns with buttons in gridview, we may need to access the row number to find the datakeys in the button click event. And here is the code how it looks like..
protected void lnkBtnCheckIn_Click(object sender, EventArgs e)
{
LinkButton lnkButton = sender as LinkButton;
GridViewRow row = lnkButton.Parent.Parent as GridViewRow;
int fleetMovemetId = 0;
int.TryParse(Gridview1.DataKeys[row.RowIndex].Values[1].ToString(), out fleetMovemetId);
}
Njoy..

Error in Asp.Net : "Redirect URI cannot contain newline characters"
While you send the error message as query string to an error page using response.redirect method in asp.net, you may come across the following error.
To get through, you should use URLEncode and URLDecode alone or with combination of HTMLEncode and HTMLDecode.
Eg:-
Response.Redirect(@"~/errorpage.aspx?.err=" + Server.UrlEncode(exception.Message) + "&.src=" + Server.UrlEncode(exception.Source));
