Drag&Drop Vs COMMAND$

IFAIK no, its set when you run your app.

I think there are (MS Windows *not* PB) limits, on how many filenames you can recieve in COMMAND$.
These can be overcome with drag and drop.
That could be a reson not to use the command line option at all, and force the user to drag and drop.
Otherwise you shold handle this.
I have at least one app that issues a warning like:
"Due to a limitation in MS Windows etc. etc."

Is there a %WM_thingy for COMMAND$ ?

SELECT CASE CBMSG
CASE %WM_INITDIALOG
' Blah blah
CASE %WM_DROPFILES
CALL GetDroppedFiles(CBWPARAM) ' Retrieve the filenames
InputStr = ""
FOR k = 1 TO UBOUND(gDroppedFiles)
InputStr = InputStr+" "+RIGHT$(gDroppedFiles(k), LEN(gDroppedFiles(k))-INSTR(-1, gDroppedFiles(k), "\"))+" "+$CRLF
NEXT
MSGBOX InputStr,," Files Dropped"
CASE %WM_COMMANDSENT ' Or something?????????????
NumFiles = 0
TempStr = " "
WHILE TempStr <> ""
INCR NumFiles
TempStr = PARSE$(COMMAND$, any " ", NumFiles)
gDroppedFiles(NumFiles) = TempStr
WEND
END SELECT

I checked win API, but once again I have no idea what the *keyword* might be short of cracking open my copy of 1479 paged Petzold.

Mike, it is generally application-dependent, however, the more flexible an application is, the better it is to use.

When you pros write an app do you write code to cover dropping files on the .exe icon as well as on the main dialog window of the .exe, or do you just offer one solution?
