C# Keys Enumeration Confused: Keys.Alt or Keys.RButton | Keys.ShiftKey | Keys.Alt
Category : Programming Languages

I was trying to test whether the Alt key was pressed.


I had a check similar to:


private void ProcessCmdKey(Keys keyData)
{
if (keyData == Keys.Alt)
{
System.Console.WriteLine ("Alt Key Pressed");
}
}

Anyways needless to say when I breakpointed when I had pressed the Alt key the debugger told me the key that was

Is it possible to use pure Encrypting and Decrypting keys in asymmetric cryptography instead of private and public keys?
Category : Programming Languages

Is it possible to use pure Encrypting and Decrypting keys instead of private and public keys? As I know in .Net asymmetric RSA implementation private key RSAParameters parameters = (new RSACryptoServiceProvider()).ExportParameters(true) is a superset of public key. And using private key we can both encrypt and decrypt our data. But I need key only for decrypting data. How to do it?

Perl: Compare keys of 2 hashes & print the difference between the closest keys
Category : Coding

UPDATE(16/1/13)


Borodin pointed out another possibility which I completely overlooked.
In the actual files (I manually sat and started looking through 46 files, each about 10MB large), there are cases where for a particular value in File1, no smaller value exists in File2 (but a greater value does).


Likewise there exist cases where for a particular value in File1, no

Java and Web development: good practices to store custom sensitive data such as private keys, API keys, etc
Category : Programming Languages

What do you advise to store custom sensitive data within a Spring MVC application (or within any other JAVA Web MVC application actually)? Let's say I've an API key and I need it to be available for my controllers. Several solutions I could think about:

2- Using a context

Do AIR applications support system wide hot keys or media keys?
Category : Web Design

I know one of the features of AIR is it lives in a sandbox on the desktop, but can a AIR application hook to system wide hotkeys or the media keys (Play, Skip, etc.) on the keyboard? In other words, can an AIR application running on the desktop respond to keypresses even if the application does not have focus.


If so, how?
