Hello:

I was hoping there where a few .NET gurus here that could help me understand some basic programming using the CRYSTALDECISIONS.SHARED and CRYSTALDECISIONS.ENGINE assemblies.

First off, here is my Powershell code to load a report, set parameters, and then displays the parameters for viewing on the screen.


[reflection.assembly]::LoadWithPartialName('CrystalDecisions.Shared')
[reflection.assembly]::LoadWithPartialName('CrystalDecisions.CrystalReports.Engine')

$report = New-Object CrystalDecisions.CrystalReports.Engine.ReportDocument
$report.Load("C:\TEMPLATE.rpt")


#hard code prompted values here
$customer = '065447'
$location = 1000
$locationsToExclude = 0
$range = New-Object CrystalDecisions.Shared.ParameterRangeValue
$range.StartValue = 1
$range.EndValue = 999

#main report parameter mapping
$report.SetParameterValue("Parent",$customer)
$report.SetParameterValue("Location",$location)
$report.SetParameterValue("@LocationsToExclude",$locationsToExclude)
$report.SetParameterValue("LocationRange",$range)

#sub reports parameter mapping
$report.SetParameterValue("Pm-SHIPMENT.PRO",'FB_Pointer.PRO')

$report.HasRecords

#$parameterField = New-Object CrystalDecisions.Shared.ParameterField

foreach ($parameterField in $report.DataDefinition.ParameterFields)
{
        write-output "The current value of:"
        $parameterField.Name
        write-output "In report:"
        $parameterField.ReportName
        write-output "is:"
        $parameterField.CurrentValues.Value
        write-output "Of kind:"
        $parameterField.DiscreteOrRangeKind
        write-output "-------------------"
}


QUESTION 1
What exactly does HASRECORDS do? If I leave out that line, the report has no data and is blank. Is HASRECORDS basically an 'execute' command?

QUESTION 2
The FOREACH loop at the end simply shows parameter values for each parameter, but the parameters on the sub report never show anything. How do I access the values of the sub reports?


Thanks for any input.
