Int32 Rec=0;
LocalID dbID;
DmOpenRef dbPP;
Int16 result;
MemHandle recordH;
DateTimeType today;
ToDoItemPtr toDoItem;
UInt16 indexP=0;
Int16 offset=0;
static char **ItemType;
TimSecondsToDateTime (TimGetSeconds(),&today);
dbID = DmFindDatabase (0,toDoDBName);
if(dbID)
{
dbPP=DmOpenDatabaseByTypeCreator
('DATA',sysFileCToDo,dmModeReadWrite);
ItemType = (Char**)MemPtrNew(1 * sizeof(Char*));
while (true)
{
DmSeekRecordInCategory(dbPP,&indexP,offset,dmSeekForward,0);
if (DmGetLastErr()) break;
recordH = (MemHandle)DmQueryRecord (dbPP,indexP);
toDoItem = (ToDoItemPtr) MemHandleLock (recordH);
if (DateToInt (toDoItem->dueDate) == toDoNoDueDate)
{
if (!(toDoItem->priority & completeFlag))
{
FrmCustomAlert(DateAlert,toDoItem->description,NULL,NULL); //giveng error
message at this line
ItemType[indexP] =
(Char*)MemPtrNew(sizeof(toDoItem->description));
StrCopy(ItemType[indexP],toDoItem->description);
break;
}
}
result = DateCompare(today,toDoItem->dueDate);
if((result==0) && (!(toDoItem->priority &
completeFlag)))
{
ItemType[indexP] =
(Char*)MemPtrNew(sizeof(toDoItem->description+1));
StrCopy(ItemType[indexP],toDoItem->description);
break;
}
MemHandleUnlock (recordH);
}
lst =
(ListType*)FrmGetObjectPtr(frm,FrmGetObjectIndex(frm,ToDayDueList));
