A customer was developing a custom namespace extension and they found that when displayed in My Computer, it showed up in the Other<\/i> category. <\/p>\n\n\n

They wanted it to appear in the Network Locations<\/i> category because it represented a network device. <\/p>\n

Explorer categorizes the items based on the SH­DESCRIPTION­ID.dwDescription­Id<\/code>. We saw this structure some time ago when we tried to detect the Recycle Bin<\/a>. By default shell namespace extensions are given SHDID_COMPUTER_OTHER<\/code> as their description ID and the clsid<\/code> is the class ID of the shell extension itself. <\/p>\n

To customize the description ID, go to the shell namespace registration and add the following: <\/p>\n

\nHKEY_CLASSES_ROOT\\\n    CLSID\\\n        {clsid}\\\n            DescriptionID=REG_DWORD:9\n<\/pre>\n
The magic number 9 is SHDID_COMPUTER_NET­DRIVE<\/code>. You can use any of the values supported by the SH­DESCRIPTION­ID<\/code> structure<\/a>. For example, if your shell extension wraps a file system directory, you may want to use SHDID_FS_DIRECTORY<\/code> so that it gets categorized under Folders<\/i>. <\/p><\/p>\n","protected":false},"excerpt":{"rendered":"
