 Posted: Mon Mar 14, 2016 11:49 pm Post subject: GET_MULTIPLE_FILENAMES bug - ROOT folder of a drive |
 |
|
I ran the example given in the HELP file to assist me with another issue. What I got was a very odd behavior.
The code is:
| Code: |
WINAPP
INCLUDE <windows.ins>
LOGICAL L,next
CHARACTER*256 filename,filter,defpath
filter = "Free Fortran files (*.f90)"//char(0)//"*.f90"//char(0) &
//"All files (*.*)"//char(0)//"*.*"//char(0)//char(0)
defpath = char(0) !Gives the current working directory
L = .TRUE.
next = .FALSE.
DO WHILE(L)
filename = char(0)
L=GET_MULTIPLE_FILENAMES@(0,"Dialog Title",filename,256,filter,defpath,next)
next = .TRUE.
IF(L) PRINT*, trim(filename)
END DO
END
|
When run against my D: drive (and I've selected a few files), I get:
| Code: |
D:\\MISCSTMT001.FXS
D:\\msdia80.dll
D:\\Multiple transfer.psd
|
The doubled backslash should not be there. I have put a check in my code to prevent this for occurring. |

Funny... I use the following code without problems - perhaps you may try it?
| Code: | WINAPP
program test
include <windows.ins>
logical*2 l,n
character*120 cpath,cfile,filter
filter = 'Image files (*.JPG)'//char(0)
cpath = char(0)
l = .true.
n = .false.
do while (l)
cfile = '*.JPG'//char(0)
l = GET_MULTIPLE_FILENAMES@(0,'Select',cfile,120,filter,cpath,n)
if (l) print*,cfile
n = .true.
end do
end |

Yep, does it here, two different Windows 10 machines.
When you ran this, were your files at the root (i.e. C:\ or D:\)?
Works fine if not at the root..... |

| Also occurs under Windows 2000, and, like Windows 10, only when selecting root level of the drive. |

Indeed, the same behaviour at my PC when searching for files in the root directory. So you may use a trick - the changes are marked with !!!:
| Code: | WINAPP
program test
include <windows.ins>
logical*2 l,n
integer*4 root
character*120 cpath,cfile,curdir@,filter
filter = 'Image files (*.JPG)'//char(0)
cpath = char(0)
root = 0 !!!
if (leng(curdir@()) == 3) root = 1 !!!
l = .true.
n = .false.
do while (l)
cfile = '*.JPG'//char(0)
l = GET_MULTIPLE_FILENAMES@(0,'Select',cfile,120,filter,cpath,n)
if (root == 1) cfile = cfile(1:3)//cfile(5:)//char(0) !!!
if (l) print*,cfile
n = .true.
end do
end |

This is fine when you are not changing the folder. However, you can use this function to go wherever you please to find files, then return the names.
The more general case is something like:
| Code: |
nnn = index(PATTERN,':\\') ! look for the odd behavior
if(nnn.ne.0) PATTERN = PATTERN(1:nnn+1)//PATTERN(nnn+3:) ! remove the :\\ and replace with : |
where PATTERN is the pathname returned. |
