There is a bug in hb_DirExists()
Fixed in the new version FWH2310 to be released very soon

Rao, as far as I know, xHarbour already have a working HB_DIREXISTS() function. To fix FWH you only have to remove this code from harbour.prg:
- Code: Select all Expand view
#ifndef __XHARBOUR__
// to be used with Harbour 3.4
// function hb_HSetCaseMatch( ... )
// return hb_HCaseMatch( ... )
#else
function hb_DirExists( cDirName )
// local cDir := CurDir(), lExists := .F.
local cDir := CurDrive() + ":\" + CurDir(), lExists := .F.
if DirChange( cDirName ) == 0
lExists = .T.
DirChange( cDir )
endif
return lExists
#endif

Master Enrico, HB_DIREXISTS() Never worked with xHarbour.
Maestro Enrico, HB_DIREXISTS() Nunca trabajo(Funcionó) en xHarbour.

Mr. Enrico
Thanks.
This function was written many years back in harbour.prg of FWH, when this function was not existing in xHarbour.
Yes the recent versions of xHarbour have this function.
We'll go by your advice.
ps: done. removed

Please, provide a sample demonstrating the problem. You can't use FWH but pure xHarbour console. Otherwise you are using the FWH modified function and not the xHarbour native one.

Thank you. As far as I read on the changelog, this function is in xHarbour lib since 2008.

He realizado esta prueba en modo consola y si ubica el archivo dentro de la carpeta de samples
#include "fileio.ch"
#define CRLF Chr(13)+Chr(10)
FUNCTION Main()
LOCAL cDir := "C:\Program Files"
IF HB_DirExists(cDir)
?cDir + CRLF + CRLF + If(IsDirWritable(cDir), "You can write in this directory.", "You have not permissions to write in this directory!")
ELSE
?cDir + CRLF + CRLF + "Directory not found!"
ENDIF
IF File("pruebadir.map")
?"Archivo si se encuentra"
EndIf
RETURN NIL
FUNCTION IsDirWritable(cDir)
LOCAL cFileName
LOCAL nFileHandle
nFileHandle := HB_fTempCreate(cDir, NIL, FC_NORMAL, @cFileName)
IF nFileHandle != F_ERROR
fClose(nFileHandle)
fErase(cFileName)
RETURN .T.
ENDIF
RETURN .F.

Sorry, I don't understand. Is that the behavior you expected or not?

Master Enrico, I don't use CONSOLE MODE. I'm saying that with FiveWin, the command NEVER worked.
Maestro Enrico, no uso el MODO CONSOLA. Lo que digo es que con FiveWin el comando NUNCA funcionó.

/*
HB_DirScan
Scan a directory tree and build a files and folders list
Syntax:
*/// HB_DirScan( <cPath>, <cFileMask>, <cAttributes> ) --> <aDirsAndFiles>/*
Arguments
<cPath> : A character string holding the drive, directory and/or file specification to retrieve information for. Default is current directory.
<cFileMask> ( skeleton > : For filter files to add to the list, (can include wild card characters). Default is ‘*.*’.
<cAttributes> : A character string holding file attributes can be specified. Information about files carrying these attributes is retrieved. One or more characters of the table below can be included in <cAttributes>. For add directories to the list add ‘D’ to <cAttributes>.
Attributes for HB_DirScan() :
Attribute Meaning
--------- -------------------------
A Archive
D Directories
H Hidden files
R Read-only
S System files
Returns
<aDirsAndFiles> : A two-dimensional array of five columns; holding information about files in the <cPath> and the that match <cFileMask>. An empty array, if no matched file found or an error occured.
Description
The HB_DirScan() function is similair to the Directory(). The first difference is that HB_DirScan() scans recursively all sub- directories in the directory specified with <cPath>. And second difference is Directory() don’t requires <cFileMask> parameter, instead this info included in the <cPath>.
The result is a two dimensional array . Columns can be accessed using #define constants from the DIRECTRY.CH file.
Constants for the HB_DirScan() array :
Symbolic Numeric
Constant Value Meaning Data Type
-------- ----- ------------------- --------------
F_NAME 1 File name Character
F_SIZE 2 File size in bytes Numeric
F_DATE 3 File date Date
F_TIME 4 File time Character
F_ATTR 5 File attributes Character
*//*
Files
Header: Directry.ch
Example
Assuming this directory tree and files exist :
C:\
| temp D
+ ---- + Dir1 D
| doc1.docx F
| test1.bat F
| test1.txt F
+ Dir2 D
| doc2.docx F

You didn't understand. The function HB_DIREXIXST() of xHarbour works fine but FWH redefined it uncorrectly. Now it should be ok.
