SetupDiRemoveDevice fails only on Vista with Invalid Handle,...

Hi,

i have some interessting Situation here. I started to port my Application
to Windows Vista32/64 and i have some strange Situation there: On Windows
2000 and XP based System the call to SetupDiRemoveDevice(....) works just
fine, but on Windows Vista based System i get a INVALID_HANDLE Error
and the call fails. What i want to know is, to wich part this Error Code
belongs and
to what Parameter. The First Parameter is a handle to a device information
set
and the second is a pointer to SP_DEVINFO_DATA structure. Both Information
"seems" to be valid, since it hold data and no NULL or Zero Info or
something
weird. Since the first parameter is a handle, at first you will think:"Ok
thats it,
backtrack the variable", but the second pointer to SP_DEVINFO_DATA holds
a so called "opaque handle (DWORD)", a handle to a device instance. So which
one is invalid? Is there a simple way to check this, to check which one is
invalid?

The Application asks (while starting) for Elevation and accepts only a
"real"
administrator and wont start another way. So this is excluded. Addtionally
it
enables all possible privileges the User Token has, so this is also
excluded.

Maybe important to know is that the application calls everything from the
..NET
PInvoke Layer, but i had no problems so far,...it started on Vista (like
many many
other problems solved so far). The first thing that comes to mind is that
some sort
of security restriction breaks my design, but i think i would get a
ACCESS_DENIED or
something like YOU_ARE_NOT_ALLOWED_TO_USE_THIS_ERROR_CODE. Its just
a INVALID_HANDLE,...

Any help would be really great!

Regards

Kerem

..NET is evil. :-)

Try writing a tiny command-line app in unmanaged C which will do the same.

Hi Maxim,

>.NET is evil. :-)

I dont know, but why none here likes .NET? .NET is not
evil, its just fine,...as long as you dont need any assembly
involved. One restriction of the application i am working
on is, that it is not allowed to have any external stuff, it
just has to be one big binary. So "tiny" console or "one
shot" binaries are not allowed.

Why does the application work on Windows 2000 and
XP, but fails on Windows Vista? Do you have any suggestions.
To be honest, i dont think thats an .NET (Layer) issue here,
since it work on prior windows version just fine!

Any ideas,...?

Regards

Kerem

Well,

i finally found it and it was not what i expected. A colleague wrote
some parts of the application, some classes plain to speak and he
was using some undocumented functions including the
SetupDiGetClassDevsEx(...)
which is undocumented i found. Switching to the SetupDiGetClassDevs(...)
made
everything just work fine.

But SetupDiGetClassDevsEx(...) works on W2K and XP just fine, but fails
with a INVALID_HANDLE_VALUE on Windows Vista. But now it has been
solved. Maybe they changed internals,...obvious they did,...

Thats why i always "try to avoid undocumented stuff,....!

BTW:

Is CM_Uninstall_DevNode(Ex)(...) the same as SetupDiRemoveDevice(...)?
Do you know anything,...?

Regards

Hi,

>What was MachineName argument of ClassDevsEx?

It was something like "\\MACHINAME". I know these
backslasches are sometimes really necesssary. But the
function did not return any error codes, thas the strange
thing here!

Nope, SetupDiGetClassDevsEx is documented. IIRC I used it already at W2K
times.

Did you actually need to call this function for a specific machine? Or it
was always a current machine?

Well,

the application mostly uses the Ex-Variants of the Functions
for future remote usage,...

Yet another evil and silly requirement. Add a native unmanaged DLL there, which will wrap around the non-.NET friendly SetupDi stuff.
