Value does not fall within the expected range - exception

Hi all,

I am getting "Value does not fall within the expected range" exception in my applecation.

I am using

Crystal report designe - Crystal Report 2011

Runtime - SAP BusinessObjects 13.0.1.220

And Visual Stdio 2010

After debugging I get to know exception is coming in this line. :: rptDoc.SummaryInfo.ReportTitle = strPDFFileName

I am trying to set ReportTitle at run time, and I am setting report title value as Guid (Operating system auto generated value like "7389fa56-693e-46ee-933a-b56c305d4d90" )

Note ::- I am not getting this exception every time, But out of 100 time I am getting it 10,11 time

Is there is some limitation of Report Title max length? or some thing else is giving this issue.

Please help me

Thanks.

Best regards,

Nitesh
