thanks john 4 u kind help and time very thanks to u.
I solve my problem the iwrk is that
1)i initialise my global variable static char* item;with 0 means static char*
item=0; and the write that function like this
static void TodayAppList(FormType* frm)
{
SysDBListItemType *dbListIDsP;
MemHandle dbListIDsH;
static UInt16 dbCount = 0;
UInt16 counter;
Boolean status;
ListType* lst;
static char **ItemType;
UInt16 ListItemNum;
if(ItemType)
{
for(counter=0;counter<dbCount;counter++)
{
MemPtrFree(ItemType[counter]);
}
MemPtrFree(ItemType);
dbCount=0;
}
if(frm)
{
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);
for (counter = 0; counter < dbCount; counter++)
{
if( StrCompare(dbListIDsP[counter].name,item)
== 0 )
CreatorId=dbListIDsP[counter].creator;
}
MemHandleUnlock(dbListIDsH);
MemPtrFree(dbListIDsP);
}
}
}
means the same way u told me .
2)i again call the function at the time of exit of application
TodayAppList(0);in the same manner u told me.
They way i m wrg is at that time i comment out the line in the function to
free memory and make the variable global and free memory at time of exit the
application.
but
i dont understand 1 thing that now i dont need to free the item any where is
my application even not need to initialise any where more like this which i m
doing that time.
item = MemPtrNew(20);
MemSet(item,20,'\0');
at the start of application bcz if i not do this it create problem to start the
application.
thanks 1 again.
do help me to solve my second problem
How do i change the bitmap dynamically on graphic button as i sescribe is the
previous thread if u can
