VB guy neds help with real code

VB guy neds help with real code

VB guy neds help with real code

(OP)
Hi all,
I know that this may not be the correct forum, but I thought I would give it a shot....
I have a snipet of C code I need a little translation on. I only know a small amount of C or ++ so I am kind of stuck. I understand that there are some values assigned in the code that you cant see because it is missing, but I am hoping that you can do you best. My main focus is what occurs with the sprintf call. Any help at all would be greatly appreciated. Here is the code:

void IS_NewPalletNumber( char PalletNumber[] )
{
   int PalletSeed;

   static char GrafTable[] = "0123456789ABCDEFGHJKLPQRTUVYX#";

   if ( LogSettings.PalletNumber >= IS_MaxPalletNumber ) {
       LogSettings.PalletNumber = 0;
   }/*if*/

   PalletSeed = LogSettings.PalletNumber;

   /* Keep the pallet numbers unique between 10 machines */
   PalletSeed += ((MachineNumber-1) * 2000);

   sprintf( PalletNumber,"%c%03d",
       GrafTable[10+(PalletSeed/1000)], PalletSeed % 1000 );

   LogSettings.PalletNumber++;
}/* IS_NewPalletNumber */

Thanks again,
Bill

RE: VB guy neds help with real code

OK, I'll give it a shot. I'm doing this from memory (which is rapidly failing me) so it may not work like it's supposed to.

SUB NewPalletNumber (PalletNumber$)
    REM void IS_NewPalletNumber( char PalletNumber[] )

    REM static char GrafTable[] = "0123456789ABCDEFGHJKLPQRTUVYX#";
    dim GrafTable$[30]
    GrafTable$[0] = "0"
    GrafTable$[1] = "1"
    GrafTable$[2] = "2"
    REM You get the general idea. You could also set this up as a string then use
    REM the INSTR function but this gives you an idea of how the C code worked
    GrafTable$[29] = "#"

    REM I assume in the original C code that LogSettings is a structure. In the
    REM BASIC code I'll assume that LSPalletNumber% and MaxPalletNumber%
    REM are global variables. MaxPalletNumber% is set somewhere else.
    REM LSPalleNumber% = LogSettings.PalletNumber
    REM MaxPalletNumber% = IS_MaxPalletNumber
    REM if ( LogSettings.PalletNumber >= IS_MaxPalletNumber) {
    REM  LogSettings.PalletNumber = 0;
    REM }/*if*/
    IF LSPalletNumber% >= MaxPalletNumber% THEN LSPalletNumber% = 0

    REM PalletSeed = LogSettings.PalletNumber;
    PalletSeed% = LSPalletNumber%

    REM /* Keep the pallet numbers unique between 10 machines */
    REM PalletSeed += ((MachineNumber-1) * 2000);
    REM I'm also assumming that MachineNumber% is a global set somewhere else
    PalletSeed% = PalletSeed% + ((MachineNumber% - 1) * 2000)

    REM sprintf( PalletNumber,"%c%03d", GrafTable[10+(PalletSeed/1000)], PalletSeed % 1000 );
    REM I'm going to break this into parts to make it easier to understand
    I% = 10 + (PalletSeed% / 1000)
    J% = PalletSeed% mod 1000
    X$ = LTRIM$(RTRIM$(STR$(J%)))
    WHILE LEN(X$) < 3
        X$ = "0" + X$
    WEND
    PalletNumber$ = GrafTable$[I%] + X$

    REM LogSettings.PalletNumber++;
    LSPalletNumber%  = PalleNumber% + 1
  
EXIT SUB


I hope that helps. As you can see, sprintf does a lot. It sets up the return string and formats it, too.
