Help with using Win32 API setupapi.dll in C#

[Michael]

Hi all,

I'm trying to figure out how to use setupapi.dll in C#, specifically the
SetupDiCallClassInstaller function.
I'm trying to develop a test suite which tests drivers and part of this
suite is checking whether devices can be successfully disabled and enabled.
I haven't found anything to support this in the .NET framework yet and seem
to be stuck interopping this Win32 API stuff.

Anybody w/ experience or know-how (C# source code examples) on how to
consume this part of the API?

Thanks,
-MH

Have you taken a look at:
http://www.pinvoke.net/default.aspx/setupapi.SetupDiCallClassInstaller

I haven't gone through to look and see if allt he "user defined types" are
also given, but that may help you out.

Adam,

Yes, I stopped by there the other day. It was a little helpful but of
limited use .

Also,

Does anybody know the proper way to populate the arguments that are passed
to the function call "SetupDiCallClassInstaller" ?

Where do I get the IntPtr for the second parameter and the SP_DEVINFO_DATA
info for the third?






WINSETUPAPI BOOL WINAPI
SetupDiCallClassInstaller(
IN DI_FUNCTION InstallFunction,
IN HDEVINFO DeviceInfoSet,
IN PSP_DEVINFO_DATA DeviceInfoData OPTIONAL
);

Parameters
InstallFunction - Specifies the device installation request (DIF request) to
pass to the co-installers and class installer. DIF codes have the format
DIF_XXX and are defined in setupapi.h. See Device Installation Function
Codes for more information. Note that for certain DIF requests, the caller
must be a member of the Administrators group. For such DIF requests, this
requirement is listed on the reference page
for the associated default handler.

DeviceInfoSet - Supplies a handle to a device information set for the local
machine.

DeviceInfoData - Supplies a pointer to an SP_DEVINFO_DATA structure that
specifies a device in the DeviceInfoSet. If DeviceInfoData is NULL, this
function calls the installers for the setup class associated with the device
information set.
