Re: Multi file selection

[Vytas]

Hi All,

I have been using cGetFile() to get user file selection. How do I go about allowing a user to select multiple files using the <Shift> and <Ctrl> keys? My search did not find anything perhaps I was not using the proper key words. Any guidance is appreciated.

Vytas,

I found the messages below in my notes. I have not tried it so I don't know if it works. Let us know.

Hi,

Found a solution. The 7th parameter of cGetFile() is the flags to control
the multiple files selection. But the cGetFile have a little bug which
ignore your previous flag if you pass in the 7th parameter.

To correct the cGetFile(), refer to line 164
   if( dwFlags )
      ofn.Flags = dwFlags;

Just change it to
   if( dwFlags )
      ofn.Flags |= dwFlags;

And everything will work perfectly well.

Lastly, the 7th parameter to pass in is hex 200 which is decimal 512

Hi James,

Thanks for the lead. I have confirmed that the seventh parameter set to 512 does in fact evoke the multi file selection option. However it also causes the file names to be displayed in short name format even if the lLongNames parameter is set to true. How to fix this problem is beyond my abilities.

My application can live with 8 character names however in this day and age others may not. If the revised code still returned the selected files in a space delimited string the parsing out of filenames containing spaces may present a bit of a challenge assuming that the item separator remains a space character.

Tanks,

Vytas

LOCAL ErrorFileDir := CurrentDrive + ":\" + "b4\AML"
LOCAL Files := cGetFile("AML File|*.txt|" + "DataBase | *.dbf |","Multi Select",1,ErrorFileDir,.f.,.t.,512)
LOCAL File := cGetFile("Txt File|*.txt|" + "DataBase | *.dbf |","Select One ",1,ErrorFileDir,.f.,.t.)
? Files,File

Output from first Multi select cGetFile
Z:\b4\AML\ BatName.txt CPM9PN~M.TXT

Output from first Single file select cGetFile
Z:\b4\AML\Copy (2) of AddProjection.txt

Vytas,

Perhaps this will help.

A working sample follows:

#include "Fivewin.ch"


FUNCTION MAIN()

    ? CGETFILE32( "*.*", "Test", , , , 2060 )

    RETURN NIL

Hi James,

It does display the files in long name format. However using either 512 or 2060 as a WinAPI flag did not let me select more than one file. Either there is a magic number required that I do not know, or I am again on the wrong track to solving this issue.

Thanks again,

Vytas

[Enrico Maria Giordano]

This is a better sample. But unfortunately it doesn't return the selected filenamed.

Code: Select all

#include "Fivewin.ch"


#define OFN_ALLOWMULTISELECT 0x200
#define OFN_EXPLORER         0x80000


FUNCTION MAIN()

    ? CGETFILE( "*.*", "Test", , , , , NOR( OFN_ALLOWMULTISELECT, OFN_EXPLORER ) )

    RETURN NIL

[James Bott]

Enrico,

What does it return? It should be returning an array, right?

James

[Enrico Maria Giordano]

It should return the selected path name followed by the selected file names, each of them NULL separated with an extra NULL at the end. What I instead see is only the path name. I think that the cause is the _retc() API used inside CGETFILE() function.

EMG

[Vytas]

Hi Enrico,

I get the same results as you. Is this a bug in FiveWin?

It seems that the only way to implement multi file select is by getting an array of files and then creating a multi item pick list. Or is there a better way?

Thanks,

Vytas

[Enrico Maria Giordano]

I get the same results as you. Is this a bug in FiveWin?

I would not call it a bug. Simply, multifile selection is not yet implemented in cGetFile().

Let's hope it will be.

[carlos vargas]

sorry for my bad english

Enrico

Plase search in hwgui or minigui functions for open files, this functions in both library permit select multi file and return a array with the file select. the sources with minimal change work in fwh.

Hi Enrico,

Thanks for taking the time to solve the issue. I hope you will forgive me for asking how do I go about compiling and linking your sample code? I run a make file (listed below) and get the following errors. I suspect it has go something to do wil paths but I am not sure what I should be modifing.
