how to zip a string

[Dave_Thomson]

   LabVIEW now has zip functions built in, allowing you to zip to a file.  But what if you want to compress a string for other use-cases?  Why can't we have a simple zip-a-string function?  For example, you might want to compress a string before transmitting it over a relatively slow buss.

It would appear to me, that if one is building a custom protocol as referenced in the example, one could develop protocols that were more efficient that zipping ever thought about being.  Honestly, I cannot think of a compelling reason to do that except to transmit verbatim data, in which case, you could write to a zip file, read it into a string and transmit... a work around to be sure, but gets it done.

If you don't mind using .NET, this might help:

OpenG has a Compress string function.
