Durgesh,
Well it's *OBVIOUSLY* because of ItemType = (Char**)MemPtrNew(dbCount *
sizeof(Char*));
You're freeing it, and then immediately allocating it again.
You could use something like the code I originally suggested where you
call the function again with a zero parameter to tidy up.
Or you could make ItemType a global, and free it on exit from your app.
Or, if you are already calling this function twice - once to set up and
once to clear, but for some reason are not able to call the function
with a zero parameter, you could rewrite the function as follows.
static void TodayAppList(FormType* frm) {
SysDBListItemType *dbListIDsP;
MemHandle dbListIDsH;
static UInt16 dbCount = 0;
UInt16 counter;
Boolean status;
ListType* lst;
static char **ItemType;
UInt16 ListItemNum;
// item = MemPtrNew(20);
//MemSet(item,20,'\0');
if(ItemType)
{
for(counter=0;counter<dbCount;counter++)
{
MemPtrFree(ItemType[counter]);
}
MemPtrFree(ItemType);
dbCount=0;
}
else
{
status = SysCreateDataBaseList(sysFileTApplication,
0,&dbCount, &dbListIDsH,true);
ItemType = (Char**)MemPtrNew(dbCount * sizeof(Char*));
dbListIDsP = (SysDBListItemType*)MemHandleLock (dbListIDsH);
if (status == true && dbCount > 0)
{
for (counter = 0; counter < dbCount; counter++)
{
ItemType[counter] =
(Char*)MemPtrNew(dmDBNameLength+1);
StrCopy(ItemType[counter],
dbListIDsP[counter].name);
}
lst =
(ListType*)FrmGetObjectPtr(frm,FrmGetObjectIndex(frm, TodayPrefList));
LstSetListChoices (lst,ItemType,dbCount);
ListItemNum= LstGetSelection (lst);
item= LstGetSelectionText(lst,ListItemNum);
MemHandleUnlock(dbListIDsH);
MemPtrFree(dbListIDsP);
}
}
}
Regards
John Sutton

Subject: RE: List draw error
here is my code 4 the list it is give memoy lick error when exit the
application static void TodayAppList(FormType* frm) {
SysDBListItemType *dbListIDsP;
MemHandle dbListIDsH;
static UInt16 dbCount = 0;
UInt16 counter;
Boolean status;
ListType* lst;
static char **ItemType;
UInt16 ListItemNum;
// item = MemPtrNew(20);
//MemSet(item,20,'\0');
if(ItemType)
{
for(counter=0;counter<dbCount;counter++)
{
MemPtrFree(ItemType[counter]);
}
MemPtrFree(ItemType);
dbCount=0;
}
status = SysCreateDataBaseList(sysFileTApplication,
0,&dbCount, &dbListIDsH,true);
ItemType = (Char**)MemPtrNew(dbCount * sizeof(Char*));
dbListIDsP = (SysDBListItemType*)MemHandleLock (dbListIDsH);
if (status == true && dbCount > 0)
{
for (counter = 0; counter < dbCount; counter++)
{
ItemType[counter] =
(Char*)MemPtrNew(dmDBNameLength+1);
StrCopy(ItemType[counter],
dbListIDsP[counter].name);
}
lst =
(ListType*)FrmGetObjectPtr(frm,FrmGetObjectIndex(frm, TodayPrefList));
LstSetListChoices (lst,ItemType,dbCount);
ListItemNum= LstGetSelection (lst);
item= LstGetSelectionText(lst,ListItemNum);
MemHandleUnlock(dbListIDsH);
MemPtrFree(dbListIDsP);
}
}
and i think it is bcz of this
ItemType = (Char**)MemPtrNew(dbCount * sizeof(Char*));
