MAPI and CustomProperties

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi,

I'm trying to set (and save) a custom property with each event, using the MAPI dataprovider.

I've added a button to the Calendar sample app with the following code:

            CalendarEvents events = frmMain.Instance.wndCalendarControl.DataProvider.GetAllEventsRaw();
            for (int i = 0; i < events.Count; i++) {
                MessageBox.Show(events[i].Id.ToString() + ": " + events[i].Subject + "\n" + events[i].CustomProperties["PowerOfficeGUID"]);
                try {
                    String propVal = events[i].CustomProperties["PowerOfficeGUID"].ToString();
                }
                catch (NullReferenceException) {
                    MessageBox.Show("CustomProperties.Count=" + events[i].CustomProperties.Count.ToString());

                    events[ i].CustomProperties["PowerOfficeGUID"] = events[i].Id.ToString(); //Just some data, will be something else in real life app
                    frmMain.Instance.wndCalendarControl.DataProvider.ChangeEvent(events[i]);
                    MessageBox.Show("CustomProperties.Count=" + events[i].CustomProperties.Count.ToString());
                }                
            }
            frmMain.Instance.wndCalendarControl.DataProvider.Save();
            frmMain.Instance.wndCalendarControl.Populate();
            frmMain.Instance.wndCalendarControl.RedrawControl();

However, after running through this code the new properties isn't there.

The messageboxes showed that a property was added, but when running the code again, the CustomProperties.Count shows zero again.

I'm simply not able to get the new CustomProperty to "attach" to the event.

What am I missing? How do I save the customproperty after adding it to the event?

Best regards,
G�ran

	Hi, Unfortunately, in the current version of the MAPI DataProvider a collection of Custom Properties is not yet supported... They are not saved correctly into MAPI. As a workaround I can recommend you to store your properties in some custom map or array. Also, one of a nearest updates should have updated DataProvider with this functionality fixed. -- WBR, Serge

	Hi Serge, How can I get some kind of uniqe identifier for the event to link my "custom map or array" and the event? The event.id for a particular event changes each time I run the Calendar sample app. The Custom Properties with the MAPI provider is very important to us, and I don't see any way we can use it without... Do you have an idea about when the a new version with support for this will be avilable? Best regards, G�ran

	Should be avalable in a nearest couple of weeks (10.3.1). Contact support (www.codejock.com/support) if you'd like to get a fix earlier. -- WBR, Serge

	Thanks Serge, I'll be experimenting with custom DataProvider for a while, so no immediate need for a fix. Best regards, G�ran
