Open multiple files via contextmenu

[starzboy]

Hello
recently i had been playing with ComamndLine, and i chose to open 3-4 files with my exe via context menu integreation.
I noticed that when i use GetCommandLine, i see "path to my exe" "1st chosen file" and the rest open in differnt instances of the app.
How to make it single instance ?
now my question is how do i get the rest of the files when i had opened ?
In general how to load more than one file via context menu integeration ?

Please help

if i remember right the shell extension should be com based, and work from DragQueryFile .. etc..
not GetCommandLine

Why do you need to do this?

What happens when you use "Send To" ?  Supposing of course you make a shortcut of your program in your "Send To" folder ?

Hmm, or maybe your proggy can detect if there's a previous instance running and pass the filename to that and then exit.

Or you could do this in this opposite way with GetOpenFileName, which can handle multiple file selection.

EDIT: Just tested, and yes, the Send To method works as expected.

Hi,

to make Windows explorer open only one instance of your program - to process multiple files - the program must be "DDE-aware". You can probably see examples of other programs which support this feature in your Windows registry. If there exists a "shell/open/ddeexec" key with a value such as "[open("%1")] or similar, then a running instance of this program will be notified by explorer via DDE about the arguments.
