You know hot the mirc icon changes depending on what ur doing, send or receiveing fdata, I wanted to do something like that with a dialog and some text. But dunno how.
Make a dialog with an icon in it then use /did -g <DialogName> <IconID> <Path\to\New\icon.ico> with a on text event. If that doesn't make sense, just use what's below.
Code:
ON 1:TEXT:*:#:{ .did -g SomeDialog 1 $mircdir\icondir\SomeIcon.ico }
