I know there are GetFirstFile and GetNextFile in LabWINDOWS,Is there such functions for Dir?

[RobertoBozzolo]

I'm not aware of a native method to obtain the directory listing; you could try using the system DIR command redirecting output to a file and reading the output file.

The command DIR /a:d /b > file.txt creates a file with the name of the subdirectories found in directory. The file can next be processed line by line to manage results.

Hope this helps

Can I achieve your method in LabWINDOWS?run some DOS command?

[RobertoBozzolo]

Yes, you can use the system () command that waits for the function to end before return.

As an alternative you can use LaunchExecutable () that doesn't wait for program conclusion or even better LaunchExecutableEx () that permits you to hide the window for the launched program. In these cases, you will need to use ExecutableHasTerminated () in a loop to be sure the process is terminated before processing the results.

I used system("command.com /C dir g:\\0907\\FT/a:d/b> FILE.txt"); But I got following in FILE.txt,

FT1601~1
FT1601~2
FT1601~3
FT1601~4
FTFAAC~1
FTFABC~1
FT1660~1
FTFA54~1
FTFA64~1
FTFA74~1
FTFA84~1
FTFA94~1
FTFAA4~1
FTFAB4~1
FTFAC4~1
FTFA3C~1
FTFA44~1
FTFA4C~1
FTFA5C~1
In fact,it should be
FT1601A-013
FT1601A-014
FT1601A-015
FT1601A-016
FT1601A-017
FT1601A-018
FT1660A-010
FT1601A-002
FT1601A-003
FT1601A-004
FT1601A-005
FT1601A-006
FT1601A-007
FT1601A-008
FT1601A-009
FT1601A-010
FT1601A-001
FT1601A-011
FT1601A-012

Depite the function names, you can use GetFirstFile() and GetNextFile() to list directory names as well.

e.g. result = GetFirstFile ("C:\\SearchPath\\*", 0, 0, 0, 0, 0, 1, fileName);

Can I get DirName[] order by name of dir?

[msaxon]

Not with that function, you would have to sort the list yourself.

Looks like that you get only the short names ( truncated to 8.3 format). If you are on NT or newer you might try cmd.exe instead of command.com
