Because it is a system process, 33 the administrator of a Windows NT system can limit Shell extension handlers to 34 those on an approved list by setting the EnforceShellExtensionSecurity value of the 35 HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer key to 1 36 (one). 37 To place a Shell extension handler on the approved list, create a REG_SZ value whose 38 name is the string form of the handler's GUID under 39 HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Shell Extensions\Approved. 40 41 The Shell does not use the value that is assigned to the GUID, but it should be set to 42 make inspecting the registry easier. 43 44 Your setup application can add values to the Approved key only if the person installing 45 the application has sufficient privileges. If the attempt to add an extension handler 46 fails, you should inform the user that administrative privileges are required to fully 47 install the application. If the handler is essential to the application, you should fail 48 the setup and notify the user to contact an administrator. 49 50 While there is no need to add values to the Approved key on Windows 95 or Windows 98 51 systems, there is no harm in doing so. The system will simply ignore them. However, there 52 is no guarantee that the key will exist on these systems. Your setup program must be able 53 to handle this case. 54 </MSDN> 55 56 We add the following entries to the respective registry key 57 "{C52AF81D-F7A0-4AAB-8E87-F80A60CCD396}"="Apache OpenOffice Column Handler" 58 "{087B3AE3-E237-4467-B8DB-5A38AB959AC9}"="Apache OpenOffice Infotip Handler" 59 "{63542C48-9552-494A-84F7-73AA6A7C99C1}"="Apache OpenOffice Property Sheet Handler" 60 "{3B092F0C-7696-40E3-A80F-68D74DA84210}"="Apache OpenOffice Thumbnail Viewer" 61 62 These shell extensions are implemented in the 'shell' project. We ignore registration 63 failures because of insufficient privileges. The reason is: On systems which restrict the 64 use of shell extensions by applying the aforementioned policy probably only people with 65 sufficient privileges are allowed to install applications anyway. On systems where the 66 use of shell extensions is not restricted registration failures because of insufficient 67 prviliges have no negative effect because the shell extensions will work anyhow. 68 */ 69 70 #ifdef _MSC_VER 71 #pragma warning(push, 1) /* disable warnings within system headers */ 72 #endif 73 #define WIN32_LEAN_AND_MEAN 74 #include <windows.h> 75 #include <msiquery.h> 76 #ifdef _MSC_VER 77 #pragma warning(pop) 78 #endif 79 80 #include <malloc.h> 81 82 #ifdef UNICODE 83 #define _UNICODE 84 #endif 85 #include <tchar.h> 86 87 struct RegistryEntry 88 { 89 TCHAR* Key;
