Hello there, 
I have an application which has the following extension embedded inside it meaning any file with that extension should be able to open up with the application. However, as a part of testing i am supposed to view the .dgn file in preview pane. but after sequencing the application and publishing it, it so happens, i'm unable to preview the .dgn files in preview pane. The source on the other hand works fine. sequencer has captured the files and registries in its entirety and no registry is missing in sequenced application. can any one help me out.

Under HKCR, for the '.dgn ' entry, are therer 'Content Type' and/or 'PerceivedType' string values? Are they the same as the native install?

To check the preview functionality is working, if you just add a 'PerceivedType' with a value of 'Text' does it show a 'txt' view?

  • Thank you for replying. I have cross checked and tripple checked my sequenced with the native install, all the entries are present in the bubble. As far as the question of content type goes this is what my registry entry looks like
    Windows Registry Editor Version 5.00

    [HKEY_CLASSES_ROOT\.dgn\ShellEx\{8895b1c6-b41f-4c1c-a562-0d564250836f}]
    @="{FA92550E-848B-4A92-9427-E57213310ADC}"
    there is no PerceivedType entry in the bubble or in the native install. I guess, PerceivedType isnt required for all the applications. Correct me if I am wrong
    • What about at the 'HKEY_CLASSES_ROOT\.dgn' level? Take a look at 'HKEY_CLASSES_ROOT\.xml' or 'HKEY_CLASSES_ROOT\.html' as examples.
      • No mate! nothing in that hive too. The Registry key I mentioned above is all that is present in the application. There's nothing more the app creates all by itself during functional validation. I guess, we can close this ticket. But not before I thank you for bringing up the ContentType and PerceivedType registry entries into picture.
