Problems using RSClientPrint

We are using VB.NET 2005 to develop a WinForms application that uses SQL Server 2005 Reporting Services to produce reports.

We want to print a large report programmatically without preview. RSClientPrint looked like a good solution but it produces an error when we try to use it.

Details...
I added Interop.RSClientPrintLib.dll Version 1.0.0.0 to my application and used the code sample I found at:
http://msdn2.microsoft.com/en-us/library/ms159195.aspx

The call to print looks like:
RSClientPrint.Print("http://ourServer/reportserver", strReportPathParameters, "Report_name")

This call generates an error message:
"An error occured during printing. (0x80004002)"

and throws an exception:
"Specified cast is not valid"

Any ideas appreciated.

I think it would help if you include in your post the line of code that sets the strReportPathParameters parameter... The entire code block would be even better.

The entire block of code follows:

Dim RSClientPrint As New RSClientPrintLib.RSClientPrint

RSClientPrint.MarginLeft = 12.7
RSClientPrint.MarginTop = 12.7
RSClientPrint.MarginRight = 12.7
RSClientPrint.MarginBottom = 12.7
RSClientPrint.Culture = 1033
RSClientPrint.UICulture = 9

Dim strReportPathParameters As String = ""
Dim strTempValue As String = ""
Dim iCounter As Integer = 0
Dim myEnumerator As IEnumerator = _
m_parameterValues.GetEnumerator
Dim aParameterValue As ParameterValue
While myEnumerator.MoveNext()
aParameterValue = CType(myEnumerator.Current, ParameterValue)
strTempValue = aParameterValue.Value
strTempValue = strTempValue.Trim
strReportPathParameters += "&" + _
aParameterValue.Name + "=" + strTempValue
End While

strReportPathParameters = "%2fAppFolder%2ftax_invoice" _
+ strReportPathParameters

'Copy from the help file
'RSClientPrint.Print("http://localhost/rtm", "%2fEmployee_Sales_Summary&ReportMonth=6&ReportYear=2004&EmpID=20", "Employee_Sales_Summary")

'Our call that generates the errors
RSClientPrint.Print("http://ourserver/reportserver", strReportPathParameters, "Tax_Invoice")

Hi mate,

I got exactly the same problem as you did, have you got any clue now?

Thanks.

|||Any updates on this situation?.. I'm in the exact same boat|||From everything I've been able to find, the RSClientPrint utility is an activex control that is only usable from client side code on a webpage, and it won't work in a winform. It also won't work being called from server side code. It must be called from the webpage itself (ie javascript).
