I need to search html pages by using the indexing services, metatags (that eventually become properties withing the Indexing service catalog) and column definitions in .asp files and in .idq files. I've done this afew times in XP but I'm struggling with Win 7. On this page: http://www.codeproject.com/KB/database/Indexing_Service_HOW-TO.aspx if you search for the title “How to add new properties for an indexed file” you will see that the column definition has to be added to the Indexing Service Registry. The tutorial says: “Add a string entry named "DefaultColumnFile" to the Registry key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ContentIndexCommon". "DefaultColumnFile" should contain the full path to your Columns Definition File.” The problem I have is that although I have done this many times in Win XP, in Windows 7 the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ContentIndexCommon does not exist and it doesn’t make any difference if I create it or not. Any help will be appreciated. Thanks

Hi, after I testing on my machine, HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ContentIndexCommon will not exist in Windows 7, but it is exist on Windows XP. As the registry in Windows 7 is not completely match with Windows XP, I suggest you try to use Windows XP Mode: Install and use Windows XP Mode in Windows 7 Furthermore, you can try to use Windows Search function in Windows 7 http://msdn.microsoft.com/en-us/library/aa965362(VS.85).aspx Hope it helps.
