Save an appointment.
Retrieve appointment information.
Export an appointment.

Steps
To save an appointment, use the
1. Before you save the appointment, to identify appointment fields that have changed since the
appointment was last saved, invoke i
commit()
2. Invoke .
if(event.isModified()) {
event.commit();
}
1. To retrieve an enumeration of appointments, invoke
ventList eventList = (EventList)PIM.getInstance().openPIMList(
E
PIM.EVENT_LIST, PIM.READ_ONLY);
Enumeration e = eventList.items();
2. To retrieve an array of IDs of fields that have data for a particular task, invoke
PIMItem.getFields()
3. To retrieve the field values, invoke
while (e.hasMoreElements()) {
Event event = (Event)e.nextElement();
int[] fieldIds = event.getFields();
int id;
for(int index = 0; index < fieldIds.length; ++index) {
id = fieldIds[index];
if(e.getPIMList().getFieldDataType(id) == STRING) {
for(int j=0; j < event.countValues(id); ++j) {
String value = event.getString(id, j);
System.out.println(event.getFieldLable(id) + "=" + value);
}
}
}
}
1. To import or export PIM item data, use an output stream writer to export tasks from the
BlackBerry® device to a supported serial format, such as iCal®.
2. To retrieve a string array of supported serial formats, invoke
PIM.supportedSerialFormats()
3. To write an item in serial format, invoke
character encoding to use when writing to the output stream. Supported character encodings
include "UTF8," "ISO-8859-1," and "UTF-16BE". This parameter cannot be null.
EventList eventList = (EventList)PIM.getInstance().openPIMList(
PIM.EVENT_LIST, PIM.READ_ONLY );
ByteArrayOutputStream bytestream = new ByteArrayOutputStream();
Enumeration e = eventList.items();
while (e.hasMoreElements()) {
Event event = (Event)e.nextElement();
PIM.getInstance().toSerialFormat(event, byteStream, "UTF8",
dataFormats[0]);
}
