We are developing a VB.NET database application, using windows forms and
Microsoft Access.
The application requires dynamic reports, where the users change data on the
forms, if a report is being shown it will automatically update.
To do this we are using the .NET crystal report viewer, which loads a
crystal report that we set it's data source at runtime using a dataset. If
the user changes data on the data collection form, we update the dataset and
refresh the reports data source.
The problem we are getting it's with the memory overhead. When we first show
the form containing the crystal viewer control, an additional 20Mb of memory
is allocated. Every time the report is then refreshed with the updated
dataset, 1-2Mb is added to the memory each time. If we close the report
viewer form, none of the memory is ever recovered. If the report is displayed
again, the memory keeps increasing with every refresh.
Is there a way to release the memory used by the crystal viewer, or is this
a know issue. If it is an issue does anyone have any better alternative to
crystal reports?
Any advise would be appreciated.

Hello,
I've scoured groups and the web, and haven't found a question like mine
answered.
I'm using Visual Studio 2003 with the Crystal Reports it comes bundled
with and SQL Server 2000. Throughout the project I'm working on, I
often find I need a temporary table displayed in a report, something
that I cannot seem to do. Since temporary tables are so useful, I
cannot imagine Crystal Reports wouldn't have a way to get such

Hi,
I will be taking on a new project developing a web-based "reporting system".
The first requirement I got from BI group is "we just want to look at the
data". Basically, there is a huge database, and they want certain people to
be able to drill down to the data they want, perhaps a few graphs here and
there, and then extract selected data to an Excel file or a flat file for
further analysis. As of now there are a handful of parameters...

I am getting mixed messages from the asp.net website hosting providers - some
say they do not support Crystal Reports due to a $25,000 per cpu licensing
fee, others say all I need to do is install Crystal Reports XI (about $500)
on a dedicated server and it will run fine.
Will Reports developed with the embeded Crystal Reports in VS 2005 run in a
Crystal Reports XI environment?

I am developing a windows application in VB.NET 2005 that includes a
number
of crystal reports.
To use the reports I use the included crystal report viewer and pass a
dataset to the report at runtime in order to report from. The issue I
am
having is with the amount of memory that the crystal viewer uses and
doesn't
recover.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
