Hi,
I have an interesting problem. I am allocating an array of strings.
This array is filled from the database and then used for populating
pop-up list. When program is ran, list pops up fine, item gets
selected, but when I tap on the trigger again I get:
"just read from the ... which is the reserved field of the
frmControlObj," bla-bla-bla.
If my clean-up portion of the code is commented out, everything runs
fine, but creates memory leaks. Clean-up portion is:
for (i = numRec - 1; i >= 0; i--)
{
MemPtrFree(programsArray[i]);
}
MemPtrFree(programsArray);
I would appreciate any ideas why it is happening. The code is bellow:
static Boolean frmNewM_trProg_OnSelect(EventPtr event)
{
ListType *list = GetObjectPtr(lstPrograms);
Int16 listItem, cardNo;
UInt32 numRec = 0;
Err err;
char** programsArray;
MemHandle record;
LocalID progLocID;
Program* prog;
int i;
MemPtr ptr;
err = DmOpenDatabaseInfo(progDB, &progLocID, NULL, NULL,&cardNo, NULL);
if (progLocID != 0)
{
err = DmDatabaseSize(cardNo, progLocID, &numRec, NULL, NULL);
}
programsArray = (char**)MemPtrNew(numRec * sizeof(char*));
for (i = 0; i < numRec; i++)
{
record = DmQueryRecord(progDB, (UInt16)i);
if (record)
{
prog = (Program*)MemHandleLock(record);
ptr = &prog->programName;
programsArray[i] = (char*)MemPtrNew(StrLen(ptr) + 1 );
StrCopy(programsArray[i], ptr);
MemHandleUnlock(record);
}
}
LstSetListChoices(list, programsArray, numRec);
listItem = LstPopupList(list);
if(listItem != -1)
{
ControlType *trg = GetObjectPtr(trProg);
CtlSetLabel(trg, programsArray[listItem]);
}
for (i = numRec - 1; i >= 0; i--)
{
MemPtrFree(programsArray[i]);
}
MemPtrFree(programsArray);
return true;
}
