Hi,

Has somebody been able to use the function cGetFile() ?

Regards.

Carles,

Its still on our todo list. We would like to fix it, or maybe we could implement one ourselves, but it could get complex.

Antonio

Nothing is complex for you

Carles,

We are building a cGetFile() of our own. We are going to publish a first prototype asap.

Carles,

Here it is:

Code: Select all

#include "FWCE.ch"

function Main()

   MsgInfo( cGetFile( "*.*", "\" ) )
   
return nil

static function cGetFile( cMask, cPath )   

   local oDlg, oBrw, oBtn, aItems, cFileName := ""

   DEFAULT cMask := "*.*", cPath := "\" 
   
   aItems = GetItems( cMask, @cPath )

   DEFINE DIALOG oDlg TITLE "Please select a file" ;
      SIZE 220, 210
   
   @ 0.4, 0.7 LISTBOX oBrw ;
      FIELDS aItems[ oBrw:nAt, 1 ], aItems[ oBrw:nAt, 2 ], aItems[ oBrw:nAt, 3 ],;
             aItems[ oBrw:nAt, 4 ] ;
      HEADERS "Name", "T", "Size", "Date" ;
      COLSIZES  100, 15, 70, 40 ;
      SIZE 100, 82 ;
      ON DBLCLICK SelFile( oBrw, cMask, @cPath, @cFileName, oDlg )

   oBrw:SetArray( aItems )
   oBrw:aJustify = { .f., .f., .t., .f. }
   oBrw:bKeyChar = { | nKey | If( nKey == 13,;
                     ( SelFile( oBrw, cMask, @cPath, @cFileName, oDlg ), oBrw:SetFocus() ),) }
   
   @ 5,  3 BUTTON oBtn PROMPT "Ok" ACTION SelFile( oBrw, cMask, @cPath, @cFileName, oDlg )

   @ 5, 10 BUTTON "Cancel" ACTION oDlg:End()
   
   ACTIVATE DIALOG oDlg CENTERED
   
return cFileName

static function CheckItem( oBrw, cMask, cPath )

   local cItem := Eval( oBrw:bLine )[ 1 ]
   local cType := Eval( oBrw:bLine )[ 2 ]
   local aItems

   if cType == "D"
      if cItem == ".."
         cPath = SubStr( cPath, 1, RAt( "\", cPath ) - 1 )
         cPath = SubStr( cPath, 1, RAt( "\", cPath ) - 1 )
         aItems = GetItems( cMask, cPath += "\" )
      else   
         aItems = GetItems( cMask, cPath += cItem + "\" )
      endif   
      oBrw:SetArray( aItems )
      oBrw:nAt = 1
      oBrw:bLine = { || { aItems[ oBrw:nAt, 1 ], aItems[ oBrw:nAt, 2 ],;
                          aItems[ oBrw:nAt, 3 ], aItems[ oBrw:nAt, 4 ] } }
      oBrw:GoTop()
      oBrw:Refresh()
   endif   

return nil

static function GetItems( cMask, cPath )

   local aInfo := Directory( cPath + cMask, "D" )
   local aItems := {}, n
   
   if Len( cPath ) > 1
      AAdd( aItems, { "..", "D", "", "" } )
   endif   

   for n = 1 to Len( aInfo )
      if "D" $ aInfo[ n ][ 5 ]
         AAdd( aItems, { aInfo[ n ][ 1 ], "D", aInfo[ n ][ 2 ],;
               DToC( aInfo[ n ][ 3 ] ) } )
      endif   
   next    
   for n = 1 to Len( aInfo )
      if ! "D" $ aInfo[ n ][ 5 ]
         AAdd( aItems, { aInfo[ n ][ 1 ], "F", Str( aInfo[ n ][ 2 ] ),;
               DToC( aInfo[ n ][ 3 ] ) } )
      endif   
   next    

return aItems

static function SelFile( oBrw, cMask, cPath, cFileName, oDlg )

   if Eval( oBrw:bLine )[ 2 ] == "F"
      cFileName = cPath + Eval( oBrw:bLine )[ 1 ]
      oDlg:End()
   else
      CheckItem( oBrw, cMask, @cPath )
   endif
   
return nil

Carles,

Using object oriented code, it gets better structured:

Code: Select all
