32/64 bit issue!

rbuser

Running XE2 on a 64bit machine but compiling 32 bit programs. Delphi apps
work fine, reportbuilder "works" fine but whenever a report is run, when
app closes down it gets the "Windows has encountered problem ...."
message. If reports not run then app closes fine.

Apps run fine under 64bit whether reports run or not!

Any suggestions as to where I could look for a solution please?

Many thanks

John B

Hi John,

This is not a known issue.

Which exact version of ReportBuilder are you using? If you create a
simple, minimal application that uses a report, are you able to recreate
this error? If so, please send the example to
support@digital-metaphors.com in .zip format and we'll test it on our 64
bit machines.

Hi John,

Are you by chance have any non-RB db controls connected to the same
datasets as ReportBuilder? If so, this can sometimes cause issues with
the new threading architecture of the multi-page preview. To resolve
the problem, you can either keep separate datasets for RB or make a call
to TDataset.DisableControls before printing the report. Something like
the following.

DataSet.DisableControls;
try
Report.Print;
finally
Dataset.EnableControls
end;

If this is not the case, my suggestion would be to begin simplifying
your application to try to isolate the problem. Start by removing all
event code associated with the report(s). Then the data access. Once
you get to a point that the report runs properly without error, begin
adding features back to isolate the issue.

?Hi Nico

I'm using the latest version of RB Std edition.

I have done what you asked and it works fine, so there is something within
the particular application itself that is peculier to when reporting is
run that is causing this. Any suggestions as to where I might look?

Many thanks

Regards

John
