I have strings separates with chr(9) in a record and this works fine:
static Boolean CreaEtiquetasList (void)
{
ListPtr lst;
CharPtr selectionText;
UInt textLen,i;
CharPtr choicesEtiquetasP;
VoidHand choicesEtiquetasH;
VoidHand choicesEtiquetasPtrsHandle;
UInt numEtiquetas = 0;
if (!(PedidosLineasDBCurrentArticulo.Etiquetas)) return false;
textLen = StrLen(PedidosLineasDBCurrentArticulo.Etiquetas);
choicesEtiquetasH = MemHandleNew(textLen+1);
if (choicesEtiquetasH!=NULL)
{
choicesEtiquetasP = MemHandleLock(choicesEtiquetasH);
for (i = 0; i < textLen; i++)
{
if (PedidosLineasDBCurrentArticulo.Etiquetas[i] == 9)
{
choicesEtiquetasP[i] = '\0';
numEtiquetas++;
}
else choicesEtiquetasP[i] =
PedidosLineasDBCurrentArticulo.Etiquetas[i];
}
choicesEtiquetasP[textLen++] = 0;
numEtiquetas++;
choicesEtiquetasPtrsHandle =
SysFormPointerArrayToStrings(choicesEtiquetasP, numEtiquetas);
lst = GetObjectPtr (PedidosDetalleEtiquetasList);
LstSetListChoices(lst, MemHandleLock(choicesEtiquetasPtrsHandle),
numEtiquetas);
}
return true;
}
