How to fix Crystal Reports Bug that causes Buffer too small for string or missing null byte error?
Details of my Page:
I have an aspnet listbox that allows multiple selects. ListBox something like this: All, House, Mechanical, Comfort, Noise, Electrical. <--small example...maybe 50 options. User can select as many options as needed. Then these options are passed through a string as parameter Issues to a stored procedure variable @Issues. However that all works.
The Problem:
When i pass the querystring to CrystalReportsViewer, I get the above error.
I have a field on the the report called:
report.SummaryInfo.ReportC
where
Comments1 = ReportTitleName <--not too big
Comments2 = selections from List which can be up to 50 words
Comments3 = EnteredByInformation <--not too big...
and depending on size of Comments2, I will get the error: Buffer too small for string or missing null byte error.
My Question:
Is there anyway to make report.SummaryInfo.ReportC
otherwise how would I fix?

i hope that helps with version question.

oh...and it doesn't happen until i load the query string into the report object and it works if i only select up to 10 options...but past that it will give the error....also error points directly to report object:
report.SummaryInfo.ReportC
report is Crystal Report Object
Private report As New CrystalDecisions.CrystalRe
If I remove one of the QueryStrings or pick less data from select object, it does not give an error.
report.SummaryInfo.ReportC
report is Crystal Report Object
Private report As New CrystalDecisions.CrystalRe

CR XI is not supposed to have a string length issue.
Is the problem when the string gets to around 254 characters?

yes...and the error that's given is exactly the one that I included...yes, but its either the buffer size is too great or the number of characters may be causing the issue...also...I noticed that the field that the data is going to is a IFieldObject...

Another note: if i add that string to an <asp:Label id="lblText"...>
the super long string will show on page...however if i try to pass it to the field on the report I get the error.
so it's not an issue with the QueryString length that i'm using to pass data with (as I thought it would be since Buffer error) or i would get an error when I pass string to lblText.Text...however when I pass that same text to CR IFieldObject, it's too big...i know it does fail when text size is: 1459. Its stops at length 511...after that it crashes.

Sounds like the CR.IFieldObject is limited to 512 hcaracters.

Thanks for your help and time...i don't think we've actually moved forward on a solution, but I'll give you all the points. you did verify what I thought was the case...Thanks for your time.
I don't think it is the Crystal length. I suspect it is an ASP or system buffer.
