Configurable number formatter.

This could be used for any type of simple hash checking. It could also be used to store a "password" that had to be verified. This code is completely managed.

This routine will get an image stored in a SQL database (IBM Informix shown here) as a BLOB and return it to the screen.

To place this on an HTML page simply add

I have an MD5 hashed version as well, but can't share that...(So you can have encrypted id's passed)

Have fun,

Strip HTML Tags From a String

Gets a regular expression that'll search for any regexp pattern specified in the parameters.

I like to have these two methods in my toolbelt, even though it's syntactic sugar, I think it aids clarity.

Truncate String

Convert a password returned by JPasswordField::getPassword() into a String.

The modus operandi for this is similar to that taken by PHP's implementation of such functions. It's comparitively memory-intensive, but is much faster than running a whole bunch of tests.

Basically, you set a mask -- an array of 256 null bytes -- and set those that correspond to characters you wish to trim. Then, rather than having to test if a character is in the set of characters to trim(O(n), or linear time on *ws), you just test once (O(1), or unit time) to see if the byte in question is set.

And of course, to trim(), you just wrap trim() around both ltrim() and rtrim().

One point of caution: these functions trim in place, so copy strings before trimming them. (Of course, if you usually want access to both pre- and post-trimmed strings, you could always make these malloc() a new string and return a pointer to it . . . )

Turns any string backwards. If you input "Test" it gives out "tseT". Hope it's useful.

The snippet shows how to use it.
