Virtual Developer Workshop: Containerized Development with Docker

Environment: VC5.0, Win95/98/NT

An Explorer context menu is the menu that pops up when you right-click on a file or folder form within Explorer or My Computer or any other standard file browse dialog.  You see them for apps like WinZip, virus scanners, image viewers, etc.  But, there is surprisingly little documentation on them, and the examples that are out there are mostly pretty poor.

I've taken the basic SHELLEX sample from the MSDN and filled in the missing parts, added multi-threading and a progress dialog and packaged it for you to use for your own applications.

The source package includes a lengthy readme file that explains the inner workings of the code, how to add your own changes, how to debug it and the things you'll need to know if you want to distribute the final product.  Please read the notes on running and debugging - shell extensions are not normal apps, you'll need to do some special setup steps before you can run or debug them.

A friendly warning:
If you've never seen a COM DLL before, this code may be confusing.  But trust me, there are only a few sections that you will have to modify in order to add your own code.

I don't know anything about the other kinds of extensions that are possible : property pages, namespace extensions, etc.  Don't ask.

Have fun!

This is distributed as a VC5 project.  I don't know if it will work on VC4 or VC6.

  • How to do it with ATL

    I'm a newcomer to ATL and COM, and I've been trying to write a context menu handler via the VC++ 6 ATL wizards. I've studied the ShellExt example from Microsoft, but it doesn't use ATL. Does anyone have a sample of an extension written with ATL? I've just posted a query on this matter in the win32.programmer.ole/ui newsgroups.

    But one question remains. If I register the dll for the class '*' it works. but if I register it for only the class e.g. '.mp3' I don't get my contest menu extension when right-clicking on a file with extension .mp3. The entries in the registry are correct.

  • Building fully functional applications using Shell Namespace Extension

    Posted by Legacy on 09/24/1999 07:00am

    I have been working on a project that fully uses Shell
    Namespace extension, with a full GUI merging with existing
    Exploer (property pages, context menu, help, drag and drop, etc.).

    Our application even goes futher to have sub namespace DLLs
    that are managed by a "master" Shell Namespace DLL, the
    framework we built can be used in any other projects that
    are hierarchical in nature, good examples are database
    viewer, file structure viewer, etc. If you have some
    questions on any of these, I may be able to help you.
