SetupDiRemoveDevice fails only on Vista with Invalid Handle,... Kerem Gümrükcü 11/1/2008 7:01:07 AM 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!

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.

Re: SetupDiRemoveDevice fails only on Vista with Invalid Handle,... Kerem Gümrükcü 11/2/2008 6:25:25 AM 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 Kerem

The standard controls need a little improvement but you can create the UI in zero time (and usually it's not simple at all - in MFC you 'd need days to do all this work...). It has a few limitations (as a Win32 wrapper) but I hope future versions of .NET will be much better. :)

Re: SetupDiRemoveDevice fails only on Vista with Invalid Handle,... "GP" <no[ at ]spam.com> 11/5/2008 4:22:50 PM Hello again! Just to clarify (this maybe the wrong topic for the kernel-dev group): The .NET Platform is surly not a Environment that shall be used for "Low-Level" Applications. Kernel Mode Development is not possible at all, and User-Mode Windows APIs are desiged to be used in a C Environment. Allthough .NET has a strong P-Invoke Layer which allows Developers to use most API Functions (allmost all User-Mode APIs can also be called from ..NET), it takes much longer to code, and it takes much longer to test. Using .NET for a Product that needs eighter very many or very complex APIs is of cause not a good choice. But saying that .NET is just (another) RAD Tool (like Delphi or VB<=6) is also wrong. The .NET Platform targets all kind of environments, not only Windows GUIs. My personal Opinion is that System.Windows.Forms is one of the Modules in .NET that are not really good (in case of Performance and Resource-Usage). I cannot speak about WPF because I haven't used it until now. Microsoft has done big investments in the .NET Platform, and it still does. For very many modern Apps it is very well suited. Like using .NET for "Low-Level" Dev-Work is a wrong choice, using C(++) for e.g. an Web-Service based Application Server or a modern Web-Application is also not very efficient. If a Product needs some Low-Level stuff why not code them in C(++), and use COM, P-Invoke or C++/CLI to make it accessable for .NET? GP
