If I know the Value of a Key, how do i get the Key itself?  If I have a PCMCIA modem, and I eject it and reinsert it, the Key changes.  I need to get the value of this Key.

hi jeffspence, what's about that

first, get all key names with tregistry.getkeynames(tstrings)
then, you go down this list in a loop and set every key as current key with tregistry.openkey(keyname,false) and try
tregistry.getvaluenames(tstrings) on it. When you know the name
of the value, this method should work
hope this help

Just a guess, does the key change any time or only if the key is kept open by your app ? Always use the CloseKey method as soon as possible.
If not, try to open the key one hierarcy step above and take rene100's solution.

Why search through the entire registry? Is the value being stored to a different root? At least, set the RootKey. That way you aren't navigating through (potentially) megabytes of irrelevent key data.
