I’m relatively new to Powershell and a complete Crystal Reports newbie. I’ve been tasked with writing a script to run a folder full of .rpts, export the results to excel, then email the results based on a .rtf (Geeze, why not something HARD?)

I’m stuck on figuring out what the .X is to get the report’s query, and how to pass parameters into a report. If you could point me in the right direction, I’d be eternally grateful. This was a great post and has helped me a bit but I could use one more nudge. Thank you in advance.

While I’ve managed to do that, I’m still stuck on one issue. My script finds all fields a table uses instead of just the ones used in the report (you know the ones with the little checkmark with them in CR).

Here’s the code I used to do that

function Get-CRTablesFields()
{

[cmdletbinding()]
param (
[parameter(ValueFromPipelineByPropertyName=$true,Mandatory=$true)]
[Alias('fullname')]
[string]$Path
)
begin
{
[reflection.assembly]::LoadWithPartialName(‘CrystalDecisions.Shared’) | Out-Null
[reflection.assembly]::LoadWithPartialName(‘CrystalDecisions.CrystalReports.Engine’) | Out-Null

}
process
{
try
{
$report = New-Object CrystalDecisions.CrystalReports.Engine.ReportDocument
$report.load($path)
$fname = Split-Path $path -Leaf

$results = $report.database.tables | select Fields

foreach ($line in $results)
{
foreach ($field in $line.fields)
{
$tbl = $field | Select TableName
$fld = $field | Select FormulaName
$aline = $fname + “`t” + $tbl + “`t” + $fld
write-output $aline
}
}

}
finally
{
$report.dispose()
}
}
}

If anyone knows where these fields that are only used in the report are hidden, please let me know.

Also, it is time consuming to explore all of the namespace for possible locations of this information. Does anyone know how to write a recursive get-member the behaves like get-childitem -recurse?

That would be fantastic! I could follow the script logic but wasn’t fluent enough in Powershell to know which parts were based on v2 compared to v1. I should be able to get the VS2008 Crystal Reports runtime on my work machine now that we’ve upgraded some of our environment to SQL Server 2008.

The script was based on the VS2008 Crystal Reports runtime.

The Get-CrystalReportTable script was written to support version 2 of PowerShell but we could strip out the V2 specific items and the basics of the script will still work. If you are interested, I can post a V1 compatible script.

I’m wrestling a little with which versions of the runtimes and CR Engines I need for this script, plus trying to learn powershell at the same time. I thought I was being smart by downloading VS2010 express, until I saw SAP’s CR .Net Engine is only released for versions up to VS2008.

I’ve discovered my work machine can only support Powershell v1 (it’s got XP SP2), but I can run Powershell v2 at home. Will the Get-CrystalReportTable script possibly run on v1 or does it use features that only v2 support?

Thank you for the explanations!
