Win32SystemSupport

BREITH Karl-Albert (AREVA)

 

Some time ago, using Windows XP, the following code piece worked just fine and returned

the correct path to gvim.exe.

 

 

Win32SystemSupport new

                getVariableWithPath: (Array with: 'SOFTWARE' with: 'Vim' with: 'Gvim')

                                               name: 'path'

                ifAbsent: [nil].

 

With Windows 7 (and Windows 8) I am getting always ‘nil’ as answer, although gvim is installed and

the registry path as given above is correct.

Has anyone a clue for me ?

 

Karl

Hi Karl,

if the Windows 7/8 Machines run on 64bit, then you need to explicitly access the 64bit or 32bit part of the registry. 

See http://msdn.microsoft.com/en-us/library/windows/desktop/ms724072(v=vs.85).aspx

Kind Regards
Karsten

Re: Win32SystemSupport

Niall Ross
Dear Karl,
    if you are running a 32 bit program (e.g. a 32 bit VisualWorks
image) on a 64 bit platform, you get indirected to the 32 bit area of
the registry automatically.  Similarly, a 64 bit image sees only the 64
bit registry keys.  Thus if your image and installed Gvim are
bit-mismatched, that could explain why you do not see the key.

A mask must be set a if running a 32 bit image on 64 but not wanting
this indirection.  (And the same for 64 bit wanting to see 32 bit,
though it could instead look explicitly in SysWOW6432.)  KEY_READ and
KEY_WRITE give the standard masks.  The base image now includes
KEY_WOW64_64_KEY and KEY_WOW64_32_KEY (see their comments).  You can
subclass Win32SystemSupport and override to set the mask, e.g.

KEY_READ
    ^super KEY_READ + (ObjectMemory is64Bit ifTrue: [0] ifFalse: [self
KEY_WOW64_64KEY])

and the same for KEY_WRITE if you want to write, and then arrange to
route the specific not-wanting-indirection call(s) through your
subclass.  This will read (and/or write) to the 64 bit key regardless of
whether your image is 32 bit or 64 bit.  Use KEY_WOW64_32_KEY to access
always 32 bit similarly.

(Obviously, only use your subclass when you need to defeat the indirection.)

Be aware there is already a Win64SystemSupport subclass of
Win32SystemSupport in Windows Messages.

             HTH
