Hi,

I'm busy evaluating the CalendarPro Active-X in a VB.NET dev enviroment for our company, and have encountered some problems implementing custom event handlers for a MySQL data source.

Implementing doRetrieveDayEvents & doCreateEvent, for example, works fine, but doUpdateEvent doesn't get fired at all.

I've implemented following code directly in the frmMain class:

        Private Sub CalendarControl_doRetrieveDayEvents(ByVal sender As System.Object, ByVal e As AxXtremeCalendarControl._DCalendarControlEvents_DoRetrieveDayEventsEvent) Handles CalendarControl.DoRetrieveDayEvents

            dbController.doQuerySelectEvents(e.dtDay, e.events, CalendarControl.DataProvider, nUserID)

        End Sub

        Private Sub CalendarControl_doCreateEvent(ByVal sender As System.Object, ByVal e As AxXtremeCalendarControl._DCalendarControlEvents_DoCreateEventEvent) Handles CalendarControl.DoCreateEvent

            dbController.doQueryInsertEvent(e.newEventID, e.pEvent, CalendarControl.DataProvider, nUserID, e.bResult)

        End Sub

        Private Sub CalendarControl_doUpdateEvent(ByVal sender As System.Object, ByVal e As AxXtremeCalendarControl._DCalendarControlEvents_DoUpdateEventEvent) Handles CalendarControl.DoUpdateEvent

            MessageBox.Show("test doupdateevent") 'temp
            'dbController.doQueryUpdateEvent(e.pEvent, CalendarControl.DataProvider, nUserID, e.bResult)

        End Sub

Am I wrong putting above code directly in the main form?

Thanks in advance,

Laurent

Hi Laurent,

This is strange. I have just tested this -- added 3 empty handlers and all 3 events are coming fine.

DoUpdateEvent comes when you move/resize/edit existing event in the calendar.

My code is like the following:

Private

Sub frmMain1_Load( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase .Load

CalendarControl.SetDataProvider("Provider=CUSTOM;")

CalendarControl.DataProvider.Open() ' Ensure that you call Open!

End Sub

Private Sub CalendarControl_DoCreateEvent( ByVal sender As Object ,

ByVal e As AxXtremeCalendarControl._DCalendarControlEvents_DoCreateEventEvent)

Handles CalendarControl.DoCreateEvent

End Sub

Private Sub CalendarControl_DoRetrieveDayEvents( ByVal sender As Object ,

ByVal e As AxXtremeCalendarControl._DCalendarControlEvents_DoRetrieveDayEventsEvent)

Handles CalendarControl.DoRetrieveDayEvents

End Sub

Private Sub CalendarControl_DoUpdateEvent( ByVal sender As Object ,

ByVal e As AxXtremeCalendarControl._DCalendarControlEvents_DoUpdateEventEvent)

Handles CalendarControl.DoUpdateEvent

End Sub

Serge,

Strange indeed, but I guess the problem was somewhere (?) in my code.

After lots of debugging, I decided to start from scratch and use the VB6 sample as an example (and read the documentation...).

A little bit embarassing, since I didn't manage to find the bug...

Anyway, everything works fine now!

Thanks for your time,

Laurent
