sorry to bother you with an other problem,but now that i moved at home and i working on my pc (OS:windows 7)i got an error message with the same code : An unhandled exception of type 'System.Exception' occurred in CrystalDecisions.CrystalReports.Engine.dll Additional information: Load report failed. on this line impbonrecepReport.Load(reportPath)

I coudnt find any thing cause the error hapend in this line Dim myParameterFieldDefinition As ParameterFieldDefinition = myParameterFieldDefinitions(PARAMETER_FIELD_NAME) i looked for numb or name and fieldname but nothing ????

i fellowed the first part of this tutorial to set myParameterFieldDefinitions : LINK TO THE TUT and i have in my table(the table linked o the crystalReport Document) field called numb that i assigned it to PARAMETER_FIELD_NAME . and still dont know where is the error ???

now i getting a message error in the next line Dim myParameterFieldDefinition As ParameterFieldDefinition = myParameterFieldDefinitions(PARAMETER_FIELD_NAME) this is the error message An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in CrystalDecisions.CrystalReports.Engine.dll Additional information: Index non valide.

i am getting some trouble with a tutorial that i found on msdn web site : http://msdn.microsoft.com/en-us/library/ms227722.aspx. i would like to pass a parameter to my CrystalReport document,but i would like to send an integer value to my CR document and just one value(because in the tut its sending and array of string values). the code is the fellowing

Private Const PARAMETER_FIELD_NAME As String = "numb"

Private impbonrecepReport As ReportDocument

Private Sub ConfigureCrystalReports()


    Dim myArrayList As ArrayList = New ArrayList()

    myArrayList.Add(999)
    Dim numbrecep As Integer

    numbrecep = 999



    SetCurrentValuesForParameterField(impbonrecepReport, myArrayList)
   
    impbonrecepReport = New ReportDocument()
    Dim reportPath As String = Application.StartupPath & "\\" & "ImpBonReception.rpt"

    impbonrecepReport.Load(reportPath)
    CrystalReportViewer1.ReportSource = impbonrecepReport

End Sub

Private Sub SetCurrentValuesForParameterField(ByVal myReportDocument As ReportDocument, ByVal myArrayList As ArrayList)

    Dim currentParameterValues As ParameterValues = New ParameterValues()


    For Each submittedValue As Object In myArrayList

        Dim myParameterDiscreteValue As ParameterDiscreteValue = New ParameterDiscreteValue()
        myParameterDiscreteValue.Value = myArrayList.ToString()
        currentParameterValues.Add(myParameterDiscreteValue)

    Next


    Dim myParameterFieldDefinitions As ParameterFieldDefinitions = myReportDocument.DataDefinition.ParameterFields
    Dim myParameterFieldDefinition As ParameterFieldDefinition = myParameterFieldDefinitions(PARAMETER\_FIELD\_NAME)
    myParameterFieldDefinition.ApplyCurrentValues(currentParameterValues)


End Sub

i got this error message

i am making a e-trade website and i have for exemple 03 products 1) Product N°1 = 5$ 2) Product N°1 = 10$ 1) Product N°1 = 8$ and when the consumer choise one product one row of matrix will be created in an other page with the name of the product and the price ---------------- product1 / 5$ ---------------- and like that with the second product and the third . and i want to store this session in the PC of the client ,cause the client can delete a product after he choise it.

the good in the Dictionary object is that can open a session in the client part(the pc of the client) and you can store the information. in the case that he refresh the page all the information still in his pc ,and that what i am looking for ,and i don't know if i can do that with PHP.
