VB.NET 'Object reference not set to an instance of an object' Loading PDF in Adobe PDF Reader Component

FamousMortimer used Ask the Experts™
Hi Experts,

I am tring to create a form with a PDF viewer in a WPF application.  I am using QuickWPFMonthCalendar that i downloaded here: http://www.codeproject.com/Articles/34052/Quick-and-Simple-WPF-Month-view-Calendar

I created a form and added an AxAcroPDF Control but i receive Object reference not set to an instance of an object error.  Here is the code on Day double click, that is supposed to load a test pdf.

    Private Sub DayBoxDoubleClicked_event(ByVal e As NewAppointmentEventArgs) Handles AptCalendar.DayBoxDoubleClicked
        MessageBox.Show("You double-clicked on day " & CDate(e.StartDate).ToShortDateString(), "Calendar Event", MessageBoxButton.OK)
        Dim frmProject As New frmProjectDetails
    End Sub

Open in new window

Which line throws the error?


Line 4.

I even tried putting this code in the form load event and it give the same error.

Thanks for the help.  It turns out that it was a 64bit app and the Acrobat component is 32bit.  Oops
