Custom viewer at F3 key for .torrent files

I'm writing application to view information from torrent files like torrentlister plugin for Total Commander.

Now at F3 key I have configured external Directory Opus viewer but at F3 key I want run may application.
I want do something lik this

if (extansion of selected file == "torrent") { torrentinfoviewer.exe full path of selected torrent file } else { Directory Opus external viewer }

How to do this in vbscript or java script ?

This is one way...

[code]function OnClick(data)
{
var cmd = data.func.command;
var tab = data.func.sourcetab;
var sel = tab.selected_files;
cmd.deselect = false;

if (tab.selstats.selfiles != 0)
{
	if (sel(0).ext == ".torrent")
		cmd.RunCommand('"C:\\path\\to\\program.exe" '+'"'+sel(0).realpath+'"');
	else
		cmd.RunCommand("Show");
}	

}[/code]
This will only pass one file regardless of how many you have selected, will pass the first selected file in the lister.

Thanks soon I Will test it

When I said one file will be passed it's only for the .torrent files, the external viewer will still get more than one passed to it.

Also had a few unnecessary characters in the one line can be changed to.

cmd.RunCommand('"C:\\path\\to\\program.exe" "' + sel(0).realpath + '"');

Do not work. After I pasted this script F3 key stoped work, external viewer also my application don't start

Are you using Opus 11? If so you might have to add @script jscript at the beginning. And/or change the function type to script I can't recall exactly how it's setup in 11 I'm using 12. Also make sure you change the path to the program.exe along with the exe name itself.

Yes I use 11 version.

I pasted this script

[code]@script jscript

function OnClick(data)
{
var cmd = data.func.command;
var tab = data.func.sourcetab;
var sel = tab.selected_files;
cmd.deselect = false;

if (tab.selstats.selfiles != 0)
{
if (sel(0).ext == ".torrent")
cmd.RunCommand('"E:\Directory Opus\Torrentinfoviewer\TorrentInfoViewer.exe" "' + sel(0).realpath + '"');
else
cmd.RunCommand("Show");
}
}[/code]

after I psted script F3 key stoped working

Make sure Function Type is set to Script Function.

Now works thanks.
