List the files in a folder

Hi Jérôme,

the DOS command file is an option,

But if you are willing to invest a bit more time, I would recommend a little DLL.

Success, Uli

I used the following

#include <windows.h>

#include <dos.h>

#include <io.h>

#include <stdio.h>

#include <stdlib.h>

/* **************************** Global Variables */

char SI1[8001];  /* Input1 Stringbuffer 8K */
char SO[8001];   /* Output Stringbuffer 8K */

XEXPORT(long)  um_showtree(void)
{  /* show all files under directory (path in $35) */
   long retval;
   all_clr();
   UGETREGS(35,SI1,sizeof(SI1)-1);                             /* Filename */
   strcpy(SO,"um_showtree starts from: ");
   strcat(SO,SI1);
   strcat(SO,"\n");
   retval = (long) dirscan(SI1,1);
   UPUTREGS(30,SO);                                  
   return(retval);
}

/* ********************************** Internal Routines ****************** */

int dirscan(char *pattern,int dmode)
{
   struct _find_t  c_file;
   unsigned attrib;
   int done, return1;
   char fullname[_MAX_PATH];
   char a[_MAX_PATH];
   char b[_MAX_PATH];

      if (pattern[0] == 0)
      { 
         strcat(strcpy(SO,"Illegal pattern: "),pattern);
         return(-2);
      };      
      make_path(pattern,a);
      if (get_fileattr(a,&attrib) != 0)
      { 
         strcat(strcpy(SO,"No file access: "),pattern);
         return(-5);
      };      
      if ((attrib & _A_SUBDIR) == 0)
      { 
         strcat(strcpy(SO,"Path not a directory: "),pattern);
         return(-6);
      };      
      done = _dos_findfirst(strcat(strcpy(b,a),"\\*.*"), _A_SUBDIR, &c_file );
      while (!done)
      { 
        if ( (strcmp(c_file.name,"..") != 0)
        &&(strcmp(c_file.name,".") != 0)  )
         {
           strcat(strcat(strcpy(fullname,a),"\\"),c_file.name);
           if ((c_file.attrib & (_A_SUBDIR) ) != 0)
           {
              if (dmode == 1)
              {
                 strcat(strcat(strcat(SO,"DIR:"),fullname),"\n");
              }
              if ((return1 = dirscan(fullname,dmode)) != 0)
                 return(return1);
              if (dmode == 2)
              {
                   if (_rmdir(fullname) != 0)
                 { 
                    strcat(strcpy(SO,"Error removing dir: "),fullname);
                    err_str();
                    return(-3);
                 };
              }
           }
           else
           {
              if (dmode == 1)
              {
                 strcat(strcat(strcat(SO,"---:"),fullname),"\n");
              }
              if (dmode == 2)
              {
                 if (remove(fullname) != 0)
                 { 
                    strcat(strcpy(SO,"Error removing file: "),fullname);
                    err_str();
                    return(-4);
                 };
              }
           }
         }
        done = _dos_findnext( &c_file );
      }
   return(0);
}

thanks Ulrich, i'll try it...

also use this dll, I must :

- Create a file dll with this code inside,

- Put the dll in the Bin folder ( with others dll),

- Make a signature with operations,

- and call it from Uniface..

Ok I'll go over there...

Hi Jerome,

no need for signature, it uses $registers for data exchange: getregs, putregs.

$35 = "C:\mydir"  ; provide a search template
perform "um_showtree"  ; just keep it going
my_list = $30
 

You can place the DLL next to the application with an INI assignment (ASN in Uniface8+):
[userdlls]
;path=..\3gl
demandload=MY123.dll,another.dll
 

Give me 2 days to prepare a Uniface 7.2.06 prototype package plus docu for you.

Anything else i can add for you to the package?
Like reading a flat file line by line, the famous USEQREAD?

Success, Uli

Hi Jerome,

another option which is already available in Uniface 7 is the interrupt statement.
You find it documented at $UUU http://march-hare.com/puuu/undoc/interrupt.html

Interruptcodes 10 will list files, interruptcode 11 subdirectories of a given mask.

file_mask = "C:\mydirectory\*.xml" ; can be relative to the workingdirectory
interrupt(10,file_mask)
list_of_files = $result
delitem list_of_files,1  ; the first is the file_mask

Perhaps this suits your needs.

From Version 8 onwards, you can use the function $ldirlist:

variables
  string  vFilePath, vContent
  numeric N
endvariables
  $dir$ = "drinks\tea"
  vContent = $ldirlist($dir$,"File")
  putmess "Files in directory '%%$dir$':"
  N = 1
  getitem vFilePath, vContent, N
  while ($status > 0)
    putmess "  %%vFilePath%%%"
    N = N + 1
    getitem vFilePath, vContent, N
  endwhile
end

Success, Uli

ok it's good Ulrich, I'll just do : dir /b /a-d > toto.txt.

Put this code in a bat file before running a startup Shell.

Thanks ( as usual) for your help, and your knowledge.

Hi Jerome,

You know all of this is available in Uniface 9 :-)

Theo.

Hi Théo,

See that with my company ;-)

I'd love Uniface 9 !!

Jérôme
