This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms

Actually, this issue is not caused by IIS, the problem occurs when the following conditions are true: The HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\fipsalgorithmpolicy registry subkey is set to 1. ASP.NET 2.0 uses the RijndaelManaged implementation of the AES algorithm when it processes view state data. The ReindaelManaged implementation has not been certified by the National Institute of Standards and Technology (NIST) as compliant with the Federal Information Processing Standard (FIPS). Therefore, the AES algorithm is not part of the Windows Platform FIPS validated cryptographic algorithms. To work around this problem, change the configuration in the application-level Web.config file. Specify that ASP.NET use the Triple Data Encryption Standard (3DES) algorithm to process...

Nested IF in Microsoft Excel

It is possible to nest multiple IF functions within one Excel formula? Answer is “YES”. You can nest up to 7 IF functions to create a complex IF THEN ELSE statement. The syntax for the nesting the IF function is: IF( condition1, value_if_true1, IF( condition2, value_if_true2, value_if_false2 )) This would be equivalent to the following IF THEN ELSE statement: IF condition1 THEN value_if_true1 ELSEIF condition2 THEN value_if_true2 ELSE value_if_false2 END IF This applies to Excel 2010, Excel 2007, Excel 2003, Excel XP and Excel 2000 Reference: Muthukumar (http://nadarmuthukumar.blogspot.in), Ref1 Hope you liked this and let me know your thoughts on post through your comments ...

Increment for loop by step n

Normally i++ increments i by 1, in order to increment i by nth count you can use i += n where n is any number. e.g. for (int i = 0; i < 11; i += 2) { Console.WriteLine(i); } Reference: Muthukumar (http://nadarmuthukumar.blogspot.in) Hope you liked this and let me know your thoughts on post through your comments...
