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 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.
