Compare two dates in Java.

Ping, PingOMatic service for an updated. Requires: The Inutio XML-RPC Library.

A simple implementation of a Java timer. Executes timer task every second.

Prior to NETCF 2.0, this was a royal pain. Now, it's pretty straight-forward.

These three related functions provide basic Clipboard operations for text. While not terribly useful by themselves, they become more useful when attached to a field's context menu or, better yet, implemented in a custom control.

Fixed missing $ sign.

From RSA Security's website:
"RC4 is a stream cipher designed by Rivest for RSA Data Security (now RSA Security). It is a variable key-size stream cipher with byte-oriented operations. The algorithm is based on the use of a random permutation. Analysis shows that the period of the cipher is overwhelmingly likely to be greater than 10^100. Eight to sixteen machine operations are required per output byte, and the cipher can be expected to run very quickly in software. Independent analysts have scrutinized the algorithm and it is considered secure."

This implementation encodes the byte stream to be encrypted "in-place".

Example:
Byte[] Key = new Byte[5] { 12, 34, 22, 12, 32 };
Byte[] B = new Byte[10] { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
// Examine B array before and after this next call.
RC4(ref B, Key);
// Examine B array before and after this next call.
RC4(ref B, Key);

This snip opens any kind of document (e.g. .PDF, .DOC, .C, .HTM, etc.) using the default application associated with it. This relies on starting a new process with the .UseShellExecute property set to true.

The main overloaded function OpenDoc(filename) will open any associated document using the default OPEN verb. If you are trying to edit a file, for example, a command file, then you need should call OpenDoc with the "EDIT" verb. Some associations also a "PRINT" verb.

Since the return result is a System.Diagnostics.Process object, you can also monitor or kill the process.

Example:
OpenDoc("C:\\SomeDocumentation.pdf");
OpenDoc("C:\\AWebPage.htm", "EDIT");
OpenDoc("C:\\Test.txt", "PRINT");
System.Diagnostics.Process doc = OpenDoc("C:\\WebPage.htm");

This only seems appropriate, we were fighting with a similar issue this morning.

More often than not, if your trying to work out what's going wrong with your subclass of InputStream, why the character encoding is getting lost in your database, or your file format reader is failing, you'll need to dump a byte buffer out in a useable form.

Here's two methods, one which appends to a StringBuffer, one which simply prints out to System.out

Tim.

(NB: The line: sb.append( "n" ) ; SHOULD have a leading slash ie: sb.append( "\n" ) ; but the formatter seems to remove it...
