Please i need some help about this problem.i want to pass an integer value as a paramater to my report using this code
cryRpt.Load(Application.StartupPath & "\SpecificAreaReport.rpt")
Dim crParameterFieldDefinitions As ParameterFieldDefinitions
Dim crParameterFieldDefinition As ParameterFieldDefinition
Dim crParameterValues As New ParameterValues
Dim crParameterDiscreteValue As New ParameterDiscreteValue
crParameterDiscreteValue.Value = Me.AreaNameTextBox.Text
crParameterFieldDefinitions = cryRpt.DataDefinition.ParameterFields
crParameterFieldDefinition = crParameterFieldDefinitions.Item("empID")
crParameterValues = crParameterFieldDefinition.CurrentValues
crParameterValues.Clear()
crParameterValues.Add(crParameterDiscreteValue)
crParameterFieldDefinition.ApplyCurrentValues(crParameterValues)
The problem is when i run this code it gives me a COM Exception which i dont understand why it is giving me that exception at this line---- crParameterFieldDefinition = crParameterFieldDefinitions.Item("empID")
