I think I've a problem with Exception in this period.

I set all appointements in my calendar control (with resources view), when I set a great quantity of item the control is showed with horizontal scrolbar and I try to move it to bring into my control the apponintement i like, but if I don't attend some second the application show me 983 exception

 'Eccezione first-chance a 0x642b922c in Visual Office.exe: 0xC000008E: Floating-point division by zero  

and at the end of them another one

Eccezione first-chance a 0x77b68ab2 in Visual Office.exe: 0xC00000FD: Stack overflow. 

ro.

each routine on my application run under structured management of errors and when an exception occurred the application show to user the problem and save a Log into a table with the information about the problem

Message, Source, StackTrace, TargetSite.ToString(), Help link and other...

but when i move the scroll bar the management of error don't intercept an exception. VS2010 show the exception on output window and then breack the application.

How can I provide you the information about the error?

The settings in Vs2010 are checked correctly in debug > exception > Common Language Runtime Exceptions but anyway when this exception occured on my debugger (vs) it show me a dialog box message that inform about the error without
the information of the detail and VS2010 open another window that inform that the origin of the stack is not available

i find the origin of the error, this is the message
[code]

'Auto,0,0,0' is not correctly for the property 'Margin'.

I'm using framework ver. 4.0

I set the Date and EndDate after creating the appointements.
The following code show you how it work

                I populate the control with appointements...

                Form_Prenotazioni.calendar.BeginInit()

                Form_Prenotazioni.calendar.Date = MyStart

                Form_Prenotazioni.calendar.EndDate = DataFine

                Form_Prenotazioni.calendar.EndInit()

                'avvia la visualizzazione del form
                Form_Prenotazioni.ShowDialog()

 

According to your opinion how I set these values?

When the new version is ready, I appreciate if you feel me through this forum.
Thanks in advance.

CreateImage method export the image like Visual method implemented in each ui control wpf.
Both work correctly but do not save the image not showed into view, when you have the scrollbar you export only a part of calendar.

honestly I don't know, because, before this error message sometimes is showed, in any case when I populate the control and I move the scrollbar fastly, is generate an unspecified error: StackOverFlow with an unknowed origin, You was been really polite to send me the new version, the first problem on the margins of the calendar was resolved, but the second, about the scrollbar continues.

Two year ago I worked with your Calendar control in windows form with the same condition and I was pleased but now I think this version has some problems to be solved, also the time is a problem on my application, for export control takes less than 1 second, for import control requires more than three minutes

I post a link contains a zip file, into you find un origin .xml exported by my calendar control with the following code

 Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles Button2.Click, Button3.Click, Button4.Click

        Select Case TryCast(sender, Button).Name
            Case Me.Button2.Name 'export
                Me.calendar.SaveTo(My.Computer.FileSystem.SpecialDirectories.Desktop.ToString & "/test.xml")
            Case Me.Button3.Name 'import
                Me.calendar.LoadFrom(My.Computer.FileSystem.SpecialDirectories.Desktop.ToString & "/test.xml")
            Case Me.Button4.Name 'cancel
                Me.calendar.Schedule.Items.Clear()
        End Select
    End Sub
