CodeProject: Property Page and Context Menu Shell Extension ATL Wizards. Free source code and programming help

These custom wizards allow you to create Property Page and Context Menu shell extensions. The objects that are created have all the interfaces that are necessary for either the Property Page or Context Menu shell extensions. Some default functionality has been added however it is recommended that the developer familiarises themselves with articles indicated in the references before editing the default auto generated code.

Installation

To install the Shell Extension Wizards you need to download shellext_dll.zip and extract the files to '???\Program Files\Microsoft Visual Studio\Common\MSDev98\Template\ATL'. You then need to register atlshlex.dll using regsvr32.exe. The Shell Extension components should then be available from ATL Object Wizard.

Usage

The shell extension components should now be available from the ATL Object Wizard.

These shell extension components have been grouped together as they both use the same page in the object creation sheet, see below. This extra page was created using the ATL Object Wizard Property Page component which is also available from this site.

This page allows you to choose whether the shell extension object applies to folder or files and if the shell extension object will be available if multiple files/folders are selected. There is also an option as to if the shell extension object will apply to all files (*) or to a particular file type. Extra file types will need to be added in by the developer.

References

Information on the IShellExt, IShellPropSheetExt and IContextMenu interfaces is available in the MSDN.

Unicode

Even though I have tested the code in unicode format I decided it was needless as I wanted the wizards to run under VC6 regardless of whether they were running under NT or Win9x.

STL

Because I have used the STL to give me extra functionality such as maps and lists etc. this code does produce known warnings when compiled under 'Warning Level 4'.

All articles are supplied as-is, as a howto on a particular task that worked for me in the past. None of the articles are supposed to be out-of-the-box freeware controls and nor should they be treated as such. Caveat emptor.

Been involved in programming from the early '80s. First on my Spectrum, then an Amstrad. Did lots of Fortran while at University before becoming involved in Forth, Prolog, Pascal, Occam, C and eventually C++. Eventually started programming on the Windows platform using Borland’s OWL framework, during my postgraduate years. When I started work in '94, I learnt MFC followed by COM and ATL and never looked back. Now working exclusively in .NET, working on WinForms, ASP.NET and the Compact Framework using C# and VB.NET. Using every bit of the .NET framework I can such as WebServices and writing my own controls for my .NET Portal, and for the Compact Framework. Still lots I don't know, but the end of the universe hasn't happened yet - I wonder if I'll have time?

I was a permanent employee for a number of companies until Dec 2000 before going independent after the DotCom I ws involved with went DotBomb. Now supplying consulting services to various institutions in London and surrounding regions i.e. UK Smile

.

Now started using BizTalk and the latest .NET framework - yeha.
