Your problem with the MemHandleUnlock in the second position is that you
have just deleted that handle with the DmDeleteRecord.
What you want to do is like this:
for (recordNeuNum = 0; recordNeuNum < numRecordsNeu; recordNeuNum ++)
{
DmSeekRecordInCategory(gVeranstaltungNeuDB, &recordNeuIndex, 0,
dmSeekForward, dmAllCategories);
recordH = DmQueryRecord (gVeranstaltungNeuDB, recordNeuIndex);
if (!recordH)
{
FrmCustomAlert(MyAlert, "Problem beim Auslesen der neuen DB!",
"", "");
err = DmGetLastErr();
break;
}
else
{
pointer_auf_neue_v= (Veranstaltung_neu *)
MemHandleLock(recordH);
neueVeranstaltung = * pointer_auf_neue_v;
// delete all old records.
TimSecondsToDateTime (TimGetSeconds (), &dateTime);
todayInt = ( ((Int32) dateTime.year-1904) << 16) + ( ((Int32)
dateTime.month) << 8) + ((Int32) dateTime.day);
dateInt = ( ((Int32) pointer_auf_neue_v->datum_jahr) << 16) + (
((Int32)
pointer_auf_neue_v->datum_monat) << 8) + ((Int32)
pointer_auf_neue_v->datum_tag);
if (todayInt > dateInt)
{
MemHandleUnlock(recordH);
err = DmDeleteRecord(gVeranstaltungNeuDB, recordNeuIndex);
deletedOldRecordsNum ++;
}
else
{
// so now, every record is in the future..
// do some stuff with this record
MemHandleUnlock(recordH)
}
}
} // next in loop
