Help with PutFile()

[Pablo César]

PS: To Rathi : Will be possible a little modification in f.PutFile() ( h_dialogs.prg ) and f.C_PutFile() ( in c_dialogs.c ) in the next release ?

This is very usefull, because according File Type selected by user, can be defined which kind of file can be used for EXPORT proposes.

Hola amigo Pablo

Thanks to remind

This was not only a wish, it was implemented too

So, (if you like) you can use it without waiting included in legal HMG distribution by admin.

Happy HMG'ing

Yeah, thanks for your tip. But it would be a common benefits to all when it will be in the next releases and Mr. Rathinagiri has already agreed with this implementation.

Thanks, you are right; probably Mr. Diamond was forgot it

Yes, I guess so... for also this question I make an update reminder in Pendings for NEXT release ( REMINDER ).

There is another question, very important now with UNICODE mode enhancements in this last HMG version, which it will demand some modification (like as C HMG_ functions) in your code of PutFile5P.prg

Which modification(s) may be required, would you specify please

Before answer this your question, let me put clear something I noted recentely.

You Esgici are indicating a 5th parameter for default indicated file at InputFile dialog. In other words and sample:

Screen75.PNG (4.45 KiB) Viewed 4246 times

By picture you can see where affects:

InputFileDialog2.jpg (40.2 KiB) Viewed 4246 times

But I as thinking in another parameter which allows to know the number option of array passed as at first parameter:

Screen76.PNG (5.26 KiB) Viewed 4246 times

Note first parameter is an array with two elements (two types of files: TXT & PRG) and by this extra parameter, we supose to take which one have been choosen by user (as above image showing).

One good example is C:\MiniGUI\SAMPLES\Applications\DBFview\source\DBFview.prg (see below part of it):

Code: Select all

Static Procedure ExportData()
Local cExt, cSaveFile, nIndex := 1, cAlias, nRecno

IF !Empty(nFocus)
	cSaveFile := PutFile( { {"DBF files (*.dbf)", "*.dbf"}, {"Text files (*.txt)", "*.txt"}, ;
		{"Data files (*.dat)", "*.dat"}, {"Excel files (*.xls)", "*.xls"}, ;
		{"Clipper, Foxpro files (*.prg)", "*.prg"}, {"All files (*.*)", "*.*"} }, , , , @nIndex )

	IF !Empty( cSaveFile )
		IF nIndex == 2
			cExt := "txt"
		ELSEIF nIndex == 3
			cExt := "dat"
		ELSEIF nIndex == 4
			cExt := "xls"
		ELSEIF nIndex == 5
			cExt := "prg"
		ELSE
			cExt := "dbf"
		ENDIF

So we're talking about different goals, here. Probably need the 6th parameter to attend both...

[Pablo César]

Which modification(s) may be required, would you specify please

For example, replacing hb_parc by HMG_parc. And add after line #pragma begindump this:

#define COMPILE_HMG_UNICODE
#include "HMG_UNICODE.h"

Mr. Rathinagiri, what do you think about 5th and 6th extra parameters in InputFile source code ? Both ideas are usefull...

[Pablo César]

I've tried to compose right code, but there some errors in C code. Here are for both codes proposed:
c_dialogs.c

Code: Select all

HB_FUNC( C_PUTFILENEW )

	if ( hb_parl(4) )
	{
		flags = flags | OFN_NOCHANGEDIR ;
	}
	
	if( strlen( HMG_parc( 5 ) ) != 0 )
      strcpy( buffer, HMG_parc( 5 ) );
    else
      strcpy( buffer, "" );
	  
	if( strlen( HMG_parc( 6 ) ) != 0 )
       strcpy( cExt, HMG_parc( 6 ) );
    else
       strcpy( cExt, "" );

    #define _MAX_FILTER 32*1024
    INT i, j=0, cont=0;
    CHAR *p = (CHAR*) hb_parc(1);
    TCHAR Filter [_MAX_FILTER];
    memset((void*) &Filter, 0, sizeof(Filter));
    
    for (i=0; *p != '\0'; i++)
    {  cont = cont + strlen(p) + 1;
       if (cont < _MAX_FILTER)
       {   lstrcpy (&Filter[j],HMG_CHAR_TO_WCHAR(p));
           /*
              TCHAR Text [100];
              wsprintf(Text,_TEXT("%d  %d  %s"),i,cont,&Filter[j]);

           j = j + lstrlen (HMG_CHAR_TO_WCHAR(p)) + 1;
           p = p + strlen(p) + 1;
       }

          break;
    }

}

h_dialogs.prg

Code: Select all

DEFAULT title := ""
DEFAULT cIniFolder := ""
 
For n := 1 TO HMG_LEN ( aFilter )
	c += aFilter [n] [1] + CHR(0) + aFilter [n] [2] + CHR(0)
Next
c :=  c + CHR(0)
Return C_PutFileNew ( c, title, cIniFolder, nochangedir, cDeFilName, cFileName )

Please Dr. Soto, would help us in this ? My C knowledges are not so good than yours.

Hi Pablo

Good suggestions, I agree with you, these enhancements will be good and useful.

By the way,

probably Mr. Diamond was forgot it

... or he didn't like it

TIA
