EOutOfResources CopyBitmap

rbuser

Hello,

we have the following problem. Our customer are working with Citrix. On
a citrix client machine there are many sessions of our application. As
Printer Driver there are Citrix Universal Printer.

It happens sometimes that the user get the exception EOutOfResources. We
know it happens during the Delphi Method CopyBitmap in Graphics.pas.
It happens only if the user show the report in a preview (not if he
print the report)

We think, that the Printer Driver is the problem.

My collegue has asked why does ReportBuilder use the printer driver for
the preview? He think, that makes no sense.
Can we change this? Is it possible to say the reportbuilder to use not
the default printer driver if the user only want to show the report in
the preview window?

Best wishes
Bernhard

For future reference, please always specify Delphi version, ReportBuilder
version, etc.


Most common cause of EOutOfResources exception is that the application is
leaking resources. I recommend running the app under a tool that check for
memory/resource leaks. AQTime and FastMem are two tools that can be used to
do this.


The printer driver is used to perform calculations about the size and
position of objects, word wrapping, etc. This is required to print
accurately. It does not use up resources, nor does it do anything with
bitmaps. To have an accurate Preview of what will be Printed, the printer
driver should be used to generate the preview.

If you prefer /not/ to use a printer driver, you can set
Report.PrinterSetup.PrinterName to Screen. It is one of the items available
in the drop down list of the object inspector, the Page Setup dialog, or can
be set via code.

Thanks for your answer.
We have all checked and there is definitive no resource leak.
On the computer where it happens there is in this moment enough free
memory. It happens always in CopyBitmap.

Try using the Delphi debugger to trace into
TppScreenDevice.CalculateScaledPageSize. That method is using the Zoom
precentage to calculated the size of a bitmap called FPageImage. The size is
calculated in screen pixels.

Try creating a very simple test application - a trivial report. And then
test to see whether that encounters the issue.

If this only happens on Citrix, then I would look to Citrix as the cause of
the issue. We have customers that use Citrix successfully, so it should be a
matter of getting things configured properly. Perhaps there is a limit to
how much memory each client app can use. Make sure in your Delphi project
you do not use auto-create forms and create/destroy forms efficiently to
conserve resource.

Now we know, that the reason is CreateCompatibleBitmap. In a simple
testapplication I'm creating with citrix many bitmaps with 256*256
pixel. On Citrix I'm only able to create 141 bitmaps. If I'm creating
bitmaps which are bigger (the reportbuilder creates bitmaps for the
preview with 926*1280), than I can more less bitmaps create.

Do anybody know if Citrix the memory for bitmaps/graphics is limiting?
The support of citrix has so far no idea. But if I don't use citrix but
Remote Desktop, I'm able to create much more bitmaps.

Now we have the solution. Citrix simulates the graphic memory. But for
each session there is only 32 MB.
We solved the problem that the user can set the color depth only to
16bit (not to 24 bit).
