Because it is a system process, the administrator of a Windows NT system can limit Shell extension handlers to those on an approved list by setting the EnforceShellExtensionSecurity value of the HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer key to 1 (one). To place a Shell extension handler on the approved list, create a REG_SZ value whose name is the string form of the handler's GUID under HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Shell Extensions\Approved. The Shell does not use the value that is assigned to the GUID, but it should be set to make inspecting the registry easier. Your setup application can add values to the Approved key only if the person installing the application has sufficient privileges. If the attempt to add an extension handler fails, you should inform the user that administrative privileges are required to fully install the application. If the handler is essential to the application, you should fail the setup and notify the user to contact an administrator. While there is no need to add values to the Approved key on Windows 95 or Windows 98 systems, there is no harm in doing so. The system will simply ignore them. However, there is no guarantee that the key will exist on these systems. Your setup program must be able to handle this case. We add the following entries to the respective registry key "{C52AF81D-F7A0-4AAB-8E87-F80A60CCD396}"="OpenOffice.org Column Handler" "{087B3AE3-E237-4467-B8DB-5A38AB959AC9}"="OpenOffice.org Infotip Handler" "{63542C48-9552-494A-84F7-73AA6A7C99C1}"="OpenOffice.org Property Sheet Handler" "{3B092F0C-7696-40E3-A80F-68D74DA84210}"="OpenOffice.org Thumbnail Viewer" These shell extensions are implemented in the 'shell' project. We ignore registration failures because of insufficient privileges. The reason is: On systems which restrict the use of shell extensions by applying the aforementioned policy probably only people with sufficient privileges are allowed to install applications anyway. On systems where the use of shell extensions is not restricted registration failures because of insufficient prviliges have no negative effect because the shell extensions will work anyhow. */ #ifdef _MSC_VER #pragma warning(push, 1) /* disable warnings within system headers */ #endif #define WIN32_LEAN_AND_MEAN #include #include #ifdef _MSC_VER #pragma warning(pop) #endif #include #ifdef UNICODE #define _UNICODE #endif #include struct RegistryEntry { TCHAR* Key;
