Activestate Perl and "Drag and Drop"

zzspectrez has asked for the wisdom of the Perl Monks concerning the following question:

Hello, I am having a bitch of time getting drag and drop to work with perl on Windows XP. It's been a while since I have been hacking around with perl.. So maybee Im just rusty. However, I remember doing this before with windows 98 no problemo. If I remember the jist.... You just use pl2bat on your perl script and then when you drop a file onto the batch file it is passed to your script in @ARGV... right??

Doesnt seem to work...
------------------------------

#!perl 

print "TEST\n";
print "ARGV: ..@ARGV..\n";
<>;
[download]

------------------------------
Then:

c:\pl2bat test.pl
c:\test.bat
HELLO
ARGV: ....

c:\test.bat test.pl
HELLO
ARGV: ..test.pl..
[download]

Ok seems to work...
Then I double click on the batch file... I get the expected.

HELLO
ARGV: ....
[download]

It waits for me to hit return then the cmd window closes.
If you drag and drop on to the batch file, the cmd window opens and then immediately closes...

vitals....
**Win Xp
**Activestate Perl
c:\perl -v
This is perl, v5.8.2 built for MSWin32-x86-multi-thread
(with 25 registered patches, see -V for more detail)
.... snip .......

.Any Suggestions???

thanks..

I think what is happening is that the `<>;` [download] is reading one line from the file that you dragged onto it, then Perl is exiting. Try `print "TEST\n"; print "ARGV: ..@ARGV..\n"; <STDIN>;` [download] On my Windows XP, drag and drop is not working at all for perl files. Did you have to set some extra registry/ftype/assoc setting? Double clicking runs okay for me. Updated: Oh, yeah, the whole pl2bat step. Yeah, that works.	[reply] [d/l] [select]

Use <STDIN> not <> or use -Mouse ? - tye	[reply]

That was it..... *Thanks...* So what did <> default to when you drag and drop?? It worked as expected (read from STDIN) untill you droped something on it. Does it default then to @ARGV or to the actual file descriptor of the file dropped on it?? Thanks!	[reply]
