Hello friends ,Am trying to run my project which involves organizer api usage and I have written a function called save,wen i click on this function ,I am getting the error as "Process 1321, thread 1322 stopped at 0x7cdc4772: A data abort exception has occurred."
my save function code is below
@void addevent::saveClicked()
{
// Read data from page
QDateTime start(m_startTimeEdit->dateTime());

QDateTime due(m_dueTimeEdit->dateTime());
if (start > due) {
    QMessageBox::warning(this, "Failed!", "Start date is not before due date");
    return;
}

m_organizerTodo.setDisplayLabel(m_subjectEdit->text());
m_organizerTodo.setStartDateTime(start);
m_organizerTodo.setDueDateTime(due);
int index = m_priorityEdit->currentIndex();
m_organizerTodo.setPriority((QOrganizerItemPriority::Priority) m_priorityEdit->itemData(index).toInt());

index = m_statusEdit->currentIndex();
QOrganizerTodoProgress::Status currentStatus = (QOrganizerTodoProgress::Status) m_statusEdit->itemData(index).toInt();
QOrganizerTodoProgress oldStatus = m_organizerTodo.detail<QOrganizerTodoProgress>();
m_organizerTodo.removeDetail(&oldStatus);
if (currentStatus == QOrganizerTodoProgress::StatusComplete && oldStatus.status() != QOrganizerTodoProgress::StatusComplete)
    m_organizerTodo.setFinishedDateTime(QDateTime::currentDateTime());
m_organizerTodo.setStatus(currentStatus);

// Save
if (m_calendarComboBox->currentIndex() > -1) {

Run your code in a debugger and see what causes the crash.

imrrk

Ok Zap I will check out..and one more thing my entries are not getting saved in device calender?

Once again, a debugger will help you see why that is so.

imrrk

whether any mistake in code?

tdmatsu

does it work on Simulator?

edit: For my defense, couple of comments above were not visible when I posted this :)

Yes, the use of a debugger is most likely the only resoure you have to find your coding errors. Maybe your program is not executing a part, which it should execute.
Nobody can answer or help you in that respect better than your own debugger.

andre

The use of a debugger, either human and/or in the form of a computer program, is your only hope of finding your problem. Both require an investment by you, either in time, in money or both.

ok. anyway, if you know that the crash is always happening in that function, i think it's just a matter of time and effort to find out which line is crashing.

happy debugging!
