Windows 7 causing issues

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   The following code gives an error on Windows 7, but works fine on Windows Vista and below.  Any ideas would be appreciated :(, there is more code to this but we broke it down to bare minimum so others can try to help us.
CComPtr<IMalloc> spIMalloc;
HRESULT hResult = ::SHGetMalloc(&spIMalloc);
LPITEMIDLIST progFolder = NULL;
hResult = ::SHGetSpecialFolderLocation(NULL, CSIDL_PRINTERS, &progFolder );
CComPtr<IShellFolder> spIShellFolder;
CComPtr<IShellFolder> spFolderProgram;
hResult = ::SHGetDesktopFolder(&spIShellFolder);
hResult = spIShellFolder->BindToObject(progFolder, NULL, IID_IShellFolder, (void **)&spFolderProgram );
CComPtr<IEnumIDList> spIEnumIDList;
hResult = spFolderProgram->EnumObjects(NULL, SHCONTF_NONFOLDERS, &spIEnumIDList );
ULONG ulCount = 0;
LPITEMIDLIST listNoFolder = NULL;
hResult = spIEnumIDList->Next(1, &listNoFolder, &ulCount ); // hResult shows an error
spIMalloc->Free(progFolder);

Any help much appreciated

	Hi, Maybe Windows7 wants first parameter to EnumObjects - some window handle. Check if our Explorer sample works with Windows 7.

	But strange thing is other CSIDL, eg. CSIDL_PROGRAMS works fine on Windows 7, it is just CSIDL_PRINTERS which is very strange. Could be a bug with Windows 7, as our code works on all OS's except this one. And the code as I said works fine with other CSIDL's just not the printer one. See Windows 7 has changed the way printers are stored by the looks of it, as it now has Devices and Printers instead of the old Printers
