How can I read the filenames from a folder
« Thread started on: Mar 19th, 2010, 11:01am » |

Hello Everyone
Could someone let me know how I can read (into some kind of variables) the filenames from a particular folder in Windows.
Many thanks
Danny

Google "MSDN findfirstfile"
or search the group files for FindFirstFile or FindNextFile. That's the API's that you need.

Hi
Running this results in the error Not in a FN or PROC
Could someone let me know what I need to do to run this. I just want to be able to read filenames into a string variable. Thanks.
LOCAL dir%, sh%, res%
DIM dir% LOCAL 317
SYS "FindFirstFile", "*", dir% TO sh%
IF sh% <> -1 THEN
REPEAT
PRINT $$(dir%+44)
SYS "FindNextFile", sh%, dir% TO res%
UNTIL res% = 0
SYS "FindClose", sh%
ENDIF
ENDPROC

The code has evidently been lifted from a PROC, because of the LOCAL, DIM...LOCAL and ENDPROC:
Code: LOCAL dir%, sh%, res%
DIM dir% LOCAL 317
...
ENDPROC
Therefore the easiest thing to do would be to use it in a PROC or FN yourself.
Trying to run the code outside a PROC or FN would risk a memory leak, because of the DIM. You could change the memory block at dir% to a structure; that would make the code more elegant and avoid the memory leak, but it's a lot of work when the alternative of putting it in a PROC or FN is so much easier.

I have written a Wiki article listing a function FNfiles which reads the contents of a disk directory into a string array (not dissimilar to Liberty Basic's FILES statement):
http://bb4w.wikispaces.com/Listing+the+contents+of+a+directory
This may be useful when you want to avoid using the Windows API directly.
