I use the following code to open and view the report (I use a CRViewer control on a form and the code is executing on
Form_Load event):

Private Sub Form_Load()

Dim crystal As CRAXDRT.Application
Dim crxBookingsOpeningsReport As CRAXDRT.Report

    Set crystal = New CRAXDRT.Application
    Set crxBookingOpeningsReport = New CRAXDRT.Report
   
        Set crxBookingsOpeningsReport = crystal.OpenReport(App.Path & "\Reports\TheatricalBookingsOpeningsGroupByCircuit.rpt")
         
    With crxBookingsOpeningsReport
        .ParameterFields.Item(1).ClearCurrentValueAndRange
        .EnableParameterPrompting = False
        .ParameterFields.Item(1).AddCurrentValue (Date)
    End With

    crxBookingsOpeningsReport.Database.Tables.Item(1).SetLogOnInfo strServerName, strDatabaseName, strUsername, strPassword
     
     Me.Left = 300
     Me.Top = 300
     Me.Width = Screen.Width - 500
     Me.Height = Screen.Height - 900

     crvBookingsOpenings.Width = Me.Width - 500
     crvBookingsOpenings.Height = Me.Height - 700
     crvBookingsOpenings.ReportSource = crxBookingsOpeningsReport
     crvBookingsOpenings.ViewReport
     crvBookingsOpenings.Zoom 120

End Sub

My report data source is a stored procedure in MS SQL Server 2000 which takes one parameter of datetime type.
The report is correctly displayed and printed in Crystal Reports. I use Crystal Reports 8.0 and VB6 (with SP6 installed)

When I open the form, I get the error:

VB6.exe application error
The instruction at "0x42e38840" referenced memory at "0x00000044". The memory could not be "read".
Click on OK to terminate the program
Click on Cancel to debug the program

If I click on Cancel button, VC++6.0 openes and I get the message:

Unhandled exception in VB6.exe(CRAXDRT.DLL): 0xC0000005: Access Violation.

Can somebody help me please ? I need an answer really fast

Try replacing your first 5 lines with these 3:

Dim crystal As New CRAXDRT.Application
Dim crxBookingsOpeningsReport As CRAXDRT.Report

    Set crxBookingsOpeningsReport = crystal.OpenReport(App.Path & "\Reports\TheatricalBookingsOpeningsGroupByCircuit.rpt")

can you test if the code works with a stored proc that does not take parameters?

if that's the problem, then i would assume the date variable is the problem. does it work when hardcoding the value?
ie: crxBookingsOpeningsReport.ParameterFields(1).AddCurrentValue CDate("3/3/1995 12:00:00 AM")
