Stored procedures
Lists the subdirectories of a given directory and returns the full paths of listed subdirectories.
Other uses: For each directory found, fListDirectory can automatically call a special procedure written in WLanguage. This procedure is used to handle the current directory. In this case, fListDirectory returns the number of listed directories.
Example
WINDEVJavaUser code (UMC)
ADirectory, ResListDirectory are strings
DirectoryToList is string
DirectoryToList = "C:\MyDocuments"
 
// List all the directories present in DirectoryToList.
ResListDirectory = fListDirectory(DirectoryToList)
// For each directory found
FOR EACH STRING ADirectory OF ResListDirectory SEPARATED BY CR
// Add the directory into TABLE_DirTable
TableAdd(TABLE_DirTable, ADirectory)
END
WINDEVJavaUser code (UMC)
DirectoryToList = "C:\MyDocuments"
 
// List the directories present in DirectoryToList.
// The DirectoryAttribute procedure returns the number of read-only directories.
ResListDirectory = fListDirectory(DirectoryToList, "DirectoryAttribute")
Syntax

Listing the subdirectories of a directory Hide the details

<Result> = fListDirectory(<Path of initial directory> [, <Options>])
<Result>: Character string
Name of listed directories, separated by CR characters (Carriage Return).
<Path of initial directory>: Character string
Path of directory from which the subdirectories will be sought.
WindowsLinux This parameter can be in Ansi or Unicode format.
Universal Windows 10 App The directory path corresponds to a relative path in relation to the current directory. The current directory corresponds to the data directory of application.
Reminder: Only the directories found in the data directory associated with the application can be used.
<Options>: Integer constant or combination of constants (optional)
Options that can be taken into account:
fdInterruptibleThe iteration can be interrupted by pressing ESC. The function will return the name of directories listed until the interruption.
Universal Windows 10 App This constant has no effect.
fPathUNICODE<Result> will be a string in Unicode format.
Universal Windows 10 App This constant is ignored.
frNotRecursiveThe iteration is non-recursive. Subdirectories are ignored.
frRecursive
(Default value)		The iteration is recursive. Subdirectories are automatically taken into account.

Listing the subdirectories of a directory by calling a procedure for each directory Hide the details

<Result> = fListDirectory(<Path of initial directory> , <WLanguage procedure> [, <Pointer> [, <Options>]])
<Result>: Integer
Number of listed directories.
<Path of initial directory>: Character string
Path of directory from which the subdirectories will be sought.
WindowsLinux This parameter can be in Ansi or Unicode format.
<WLanguage procedure>: Procedure name
Name of the WLanguage procedure ("callback") called for each listed directory. This procedure is used to handle the current directory.
For more details on this procedure, see Parameters of the procedure used by fListDirectory.
<Pointer>: Optional integer
Pointer passed to <Procedure name>.
<Options>: Combination of Integer constants
Type of iteration performed for the directory files:
fdInterruptibleThe iteration can be interrupted by pressing ESC. The function will return the number of directories listed until the interruption.
fPathUNICODE<Result> will be a string in Unicode format.
frNotRecursiveThe iteration is non-recursive. Subdirectories are ignored.
frRecursive
(Default value)		The iteration is recursive. Subdirectories are automatically taken into account.
Remarks
