Binary Display Formatter

I would like to be able to display a binary string in the following format:

8 bits:

0000 0000

16 bits

0000 0000 0000 0000

32 bits

0000 0000 0000 0000 0000 0000 0000 0000

Yet when I grab the string, i want to eliminate the space.

Can I perform this task without haveing to tokenize the string to read it every time i want the data.

It there away to build a display formatter...but for the display only..not having to manupulate my original string??

Thanks
