Hi
anyone know where i can found informations about registry keys and
particulary how HKEY_CLASSES_ROOT is builded and structured.
I'am doing a function that get all verbs for given extension.

The algorith that do this is:
1.i have Extension="pdf"
2. i look in HKCR for key "*.pdf"
3.after i find it i look ValueData for HKCR\.pdf\(Default) and i find what
application is default for this ValueData = "AcroExch.Document"
4. now i look for verbs (Keys) under HKCR\AcroExch.Document\Shell\

This works fine but on some computers i dicsovered that they don't have
"Shell" key ,but they have "CurVer" key and if you look you have another
ValueName "(Default)" that point to "AcroExch.Document.7". Where this ends?
Is there any FAQ or HOWTO how this works? Links?

PS:i am developing this under VB6

The Registry in completely proprietary to Microsoft and they can
pretty well do what they like with from one version of Windows to
the next.

Are you, perchance, trying to open a pdf file in whichever application
the user prefers? If so, use the ShellExecute API call directly on the
pdf file; that way Windows can work out what to "open" it with ...
