  • .NET - alpha-numeric representation of numbers

    - by mack369
    I'm implementing serial key functionality in my application. User needs to enter at least 64bit number in order to register the application. Because typing number like 9,223,372,036,854,775,807 will take a while I want to compress it a bit. The first guess was to code this number hexadecimally but it still is quite long (0x7FFF FFFF FFFF FFFF). Is there any standard method in .NET to code this number alphanumerically using for example: digits, upper-case and lower-case characters?

  • java beginner- in which folder should I place a "database.properties" file

    - by Arvind
    I read some tutorials on how to read data from a database.properties file- which basically stored key-value pairs. What i want to know is, in which folder should I place this file? Is it in the root (ie "src") or within a package... And how do I access this file, if it is placed in "src"- my code will be within a package (and the package's directory will be under src)- so how do I access the properties file, which is in "src", from a class within a package?

  • Passwordless SSH using cgi-perl script

    - by AV
    Hello, This is my first shot at trying out cgi-perl scripts. I have SSH keys set up between my (root user) local machine and a remote machine. I'm trying to run a command on the remote box and display the output on a webpage hosted from my local machine. The script runs fine from command line however, it throws SSH key error when called from the webpage because the user running the script is apache and not root. Is there a way to get around this issue?

  • NSTextField enter to trigger action

    - by Chris
    I've been looking all over for a simple example of how to have an action (or button) be triggered when the enter key is hit in the text field. Should I subclass the text field? Would I need to set a delegate to call the action I need? Is there a way to catch the event in my main window controller class? If you could even just point me to the right direction that would be great. Thanks.
