Files to Programs links

[Aldo Cavini]

Peter, Wayne --

sorry I'm a registry novice I looked through the Win32Api help file and it is not easy to understand. Peter, I didn't know how the SendTo menu work; now I'm puzzled on two more questions:
1- How to create a shortcut file by program
2- Where to write it - that is, how to get the USER path to reach the SendTo folder

(and, of course, I still need help on the automatic extension files process on esplorer).

Thanks

I work with SendTo without using the registry:
Just copy a shortcut to your program to the SendTo-folder.
In your program you can obtain the file name by using command$.
If multiple files is selected, you get a " "-delim. list.
The only problem is that if too many files is selected, an
error occurs.

Peter, thanks a lot - Now I know the correct way to manage the registry entries.

Now I need the registry key names to do what I want. That is, the keys to add an entry to the SendTo menu, and the keys to link a file extension to an application program.

Is this what you are looking for?

I would like to add a PB program the two following capabilities (bBoth capabilities should be enabled/removed as a response to DDT checkboxes):

1 - Add/remove an entry to the Send To menu
2 - Create/delete the automatic link to the file extension (double-clicks on explorer)

I think I must use the registry, both write and read (read to get the initial status of my checkboxes inside the DDT). Can someone tell me the main "tricks" to do this? Any help would be greatly appreciated.
