Hello sir,
I have created crystal report in vb.net 2005 with TOAD as backend.
when i generate report for example the date between 1/1/2007 to 3/3/2007
somtimes i will get an output with out any problem but sometime you i will
get this error
A callback was made on a garbage collected delegate of type
'CrystalDecisions.ReportAppServer.DataSetConversion!CrystalDecisions.ReportAppServer.DataSetConversion.DataSetConverter+CrdbAdoPlusDelegate::Invoke'.
This may cause application crashes, corruption and data loss. When passing
delegates to unmanaged code, they must be kept alive by the managed
application until it is guaranteed that they will never be called.
and then if i press continue i will get this error display
error in file c:\docume~1\mohammad\LOCALS~1\Temp\temp_dd{}.rpt:The request
could not be submitted for background processing.
for the same parameter.
when i uncheked the MDA option "collected delegate" i will get the follwing
error
error in file c:\docume~1\mohammad\LOCALS~1\Temp\temp_dd{}.rpt:The request
could not be submitted for background processing.
once in 5 or 10 times i can't say
So, please help me
I am in big trouble
I hope you got it please mail me on (e-mail address removed)
