Hey guys,

I need your help, actually with two mostly-separate things.

1) I need to find a way to add an entry to the context menu in Windows Explorer so that when the user selects a file or folder, it has a new option for "Import". Once the user selects that menu item, it needs to call a custom-built EXE (written in VB.NET 2005), passing the selected file/folder path as an arg.

Here's the good news - I found an easy way to do it, but it works just for folders. If I add, in the registry, an entry under HKEY_CLASSES_ROOT/Folder/Shell an entry called "Import", and under that an entry called "command", and set the default of that entry to the path to my EXE (plus %1 as the end to pass the path), it works for folders.

But I cannot figure out a way to do it for files.

2) If the user selects two folders, or two files, or a file and a folder, I want it to open one instance of my EXE with both paths passed to it. I think the way to do this is to keep it with the one "path" arg, but add code to the module such that if the EXE is already in memory and running, just add the new path to it (probably via a public sub or function) rather than starting up a new instance of the form.

Unfortunately, I can't figure out either how to check if it's already running, nor how to transfer data to the already-running instance of it so that I can add the other items to it.

Also bear in mind that I'm writing this in VB.NET (2005).

Any ideas?

Bearing in mind that you have access to the same APIs as the other .Net languages, including C++, take a look at the source code for TortoiseCVS or TortoiseSVN, which both do exactly what you're looking for.

And if there isn't a native .Net version of the function you want, I know for sure you can also call raw Win32 APIs from VB.net, because I've done it myself. (God knows why the plaform SDK doesn't have full coverage in .Net. Rolling Eyes
