This is the best method as far as I can think.

2. The lazy option – change registry key to accept more or infinite numbers

regedit - > navigate to

HKEY_LOCAL_MACHINE/SOftware/Crystal Decisions/Report Application Server/InprocServer/ReportDocument

Change the value of the field MaxNumOfRecords to -1(For Unlimited No. of records)

 

Your sys admin may sue you for changing this J

 

3. I like writing more code, give me an option – ok now for you, the option is create a factory class and when creating class check if the max has reached and clear the old ones. (Not a good idea isn’t it?)

public class ReportFactory
{
    protected static Queue rptQueue = new Queue();

    protected static ReportClass CreateReport(Type reportClass)
    {
        object report = Activator.CreateInstance(reportClass);
        rptQueue.Enqueue(report);
        return (ReportClass)report;
    }

    public static ReportClass GetReport(Type reportClass)
    {
        if (rptQueue.Count > MAX_COUNT) ((ReportClass)rptQueue.Dequeue()).Dispose();
        return CreateReport(reportClass);
    }
}

Choose your own method, as I mentioned my fav is the first one...

Good luck
