I want to read the data from a database and set them in a list in a
dynamic way, I mean without caring how many fields that database
has. The code I�m using is:
static void FillList(DmOpenRef Base, ListType *lst)
{
char **itemList;
char * recPtr = NULL;
MemHandle recHandle;
int probe, numOfRecords;
numOfRecords = DmNumRecords(Base);
probe = 0;
itemList = (char **) MemPtrNew(numOfRecords * sizeof(char*));
gListChoices = itemList;
gListNumItems = numOfRecords;
while (numOfRecords > probe){
recHandle = DmGetRecord(Base, probe);
if (recHandle == NULL)
ErrDisplay ("ERROR");
recPtr = MemHandleLock(recHandle);
itemList[probe] = recPtr;
DmReleaseRecord (Base, probe, true);
probe++;
if (recHandle)
MemHandleUnlock(recHandle);
}
LstSetListChoices(lst, itemList, numOfRecords);
}
Code in frmOpenEvent (MainFormHandleEvent):
list = (ListType *)FrmGetObjectPtr (frmP,
FrmGetObjectIndex(frmP, MainList));
FillList(UbicDB, list);
LstSetSelection(lista, 0);
Code in frmCloseEvent (MainFormHandleEvent):
if (gListChoices) {
for (i=0; i<gListNumItems; i++){
MemPtrFree((MemPtr) gListChoices[i]);
MemPtrFree((MemPtr) gListChoices);
gListChoices=0;
}
}
When I execute the program only the first field appears and nothing
more.
PD: When I create the list I put 1 visible item (I can't put more
because the CodeWarrior Linker says that no fields exist for the
list, this value can�t be bigger than 1 and my idea is to creat the
fields at runtime) so I don�t put any field.
Thanks.
