programming with the registry

Hi,

i'm interested in finding out about programming with the windows registry.  Does anyone know of a good general guide to using it from VB - and most importantly - what contraints there are?  i.e. I assume we're not meant to put massive amounts of information in the registry - if everyone did that it would get unstable pretty quickly wouldn't it?

is there a limit to what we should store in the registry?  Is there a guide to "good programming practices" for the registry anywhere that anyone knows of?

thanks

Ken

VB comes with some simple registry readers and writers, for example:

SaveSetting "AppName", "Section", "Key", "Data"
ThisSetting = GetSetting"AppName", "Section", "Key")

this has a limitation, because keys using these built-in functions are only ever stored beginning at this location:
HKEY_CURRENT_USER\Software\VB and VBA Program Settings

if you want to be able to read/write keys to/from different locations, you can do a private declare to a win32 api call within VB.

some general guidelines for registry:

- store user specific data (or machine-specific) for your app in the registry. if you must store more than 50 pieces of data, it's usually best to implement a text file or DB, so as not to clog up the registry.

small error above. should be:

ThisSetting = GetSetting("AppName", "Section", "Key")
