Just can't stay away

I have tested several approaches to detect the case when a requestfile is canceled. None works (OS4.1 Update 6,, not tested on OS4.1FE
(for requeststring there are no such problems)
eg


unset m  ; can i test if m is set?

 set m `REQUESTFILE TITLE="Choose your music"`

 echo $m  ;prints $m  if canceled 

 ; if $m EQ ""

 if $m EQ "\$m"

    echo "No music"

 endif

 unset m

Has anyone a suggestion ?

@JosDuchIt

Try to keep it simple, this should work


DELETE T:music FORCE QUIET

REQUESTFILE TITLE="Choose your music" ACCEPTPATTERN="*.(mp3|mod|wma|m4a)" TO T:music

IF NOT WARN

  ;play music command goes here, eg.

  playtunes <T:music

  DELETE T:music FORCE QUIET

ELSE

  ECHO "No Music"

ENDIF

If the redirection doesn't work try:


IF NOT WARN

  SET m `TYPE T:music`

  playtunes "$m"

  UNSET m

ENDIF

or simpler:


IF NOT WARN

  playtunes `TYPE T:music`

ENDIF

If IF NOT WARN doesn't work you can use IF EXISTS T:music instead as the file isn't created if you cancel the requester.

edit: changed code a little to remove pointless if exists check.

@JosDuchIt

This should work:


set m ""

set m `REQUESTFILE TITLE="Choose your music"` 

if $m EQ "" 

   echo "No music" 

endif

Quote:

can i test if m is set?

Yes:


get >nil: m

if warn

  echo "m is not set"

else

  echo "m is set to $m"

endif

Quote:

set m ""
set m `REQUESTFILE TITLE="Choose your music"`
if $m EQ ""
echo "No music"
else
echo "music $m"
endif

saved as thomas.bat & protected +S
gives me the following output

5.Stock:Backup_Datas/Gui4Cli/C/RTF-Riddle> thomas.bat
music Thomas.bat

when selectingt the script
5.Stock:Backup_Datas/Gui4Cli/C/RTF-Riddle> thomas.bat
music

when hitting cancel

It does not seem to solve the issue imho a canceled requestfile returns something that looks like an empty string but is not?

Sorry, I didn't see the missing quotation marks. The if statement has to look like this:


if "$m" eq ""
