[REBOL] Re: More REBOL IOS questions.

Hi Ed,
<< Does REBOL View, for example, support a drag & drop interface? I have
seen no evidence of this, but admit that the time I've spent looking at
it is probably no more than two hours. >>
Allen Kamp has done some really nice demos of D&D inside View apps. Getting
D&D events from Windows is another matter. I haven't tried catching
WM_DropFiles, though it may be possible. The new SYSTEM port may allow
catching WM_ messages but I haven't tried it.
<< Can REBOL call external applications? I know it can connect to Oracle
through ODBC and I assume it can through TNS Names, but can it call
other applications (at least through OS calls) and execute them with the
appropriate parameters? Case in point: can it call SQL*Plus, pass the
User and Password and script to be run? >>
View/Pro and Command can. The Link client still can't AFAIK. We have a
script on our IOS server that doesn't run under Link, because we need to do
that. No problem running that way if you don't mind doing it.
<< I know IOS can detect file changes. Can it intercept those changes
programmatically? Can we use it to create a log of files that have been
changed?
Not sure exactly what you mean, but probably yes. If you're going through
IOS, you will see items published and, if you're writing your own post-func
for your reblets, you can act on that. You could also have a daemon-type
process that polls for things if that will work for you. Callbacks might be
possible with the new system port as well, but I haven't tried it so I don't
know, under Windows, if you can use the file-change notification APIs.
