How to keep Crystal Reports 2008 (libraries, dlls) Load resident in memory

We have several C# programs that are called thru out the day which in turn call crystal to print a particular report.  It takes forever on the first load and then if you proceed to print more they are quicker.  From what I read that is because each time you call the Load it has to load up some libraries (which ones would be nice to know ?), does it check to see if these are already loaded in memory?  If so is there a way to keep these loaded in memory so we don't have this delay everytime.  We tried creating a service to have the Crystal up and running, but that didn't seem to work or we did it incorrectly.

Please re-post if this is still an issue to the .NET Development - Crystal Reports Forum or purchase a case and have a dedicated support engineer work with your directly.
Load a dummy report and keep it in memory so it keeps the dependencies in memory

  • How to integrate Crystal Report 2008 with java

    Currently we are using Crystal Report XI with our application, it is working fine. Now we are updating to Crystal Report 2008.
    We have build our application in enterprise archive file. There is a web archive file(.war) file in the EAR file which contains the crystal report. Inside the .war file we have reports folder which contain jsps and rpt folder. the jsps folder contains the crystalreportviewers12 folder and .jsp files. The rpt folder contain the.rpt files. The WEB-INF which is at the reports folder leavel contains the classes and lib folder.  The crystal report jars are in the lib folder and the CRConfig.xml file inside the classes folder.  I replaced all the crystal report jar with Crystal Report 2008 jars, modified the web.xml and the CRConfig.xml file accordingly. When I opened the report it gave me an error.
    When the following line was execuated in the jsp:
    reportClientDocument.open(report, 0);
    it gave me following error:

    Hello Ted,
    As per the samples in the link provided by you I identified that the following statement was missing.
    reportClientDocument.setReportAppServer(ReportClientDocument.inprocConnectionString);
    After adding this statement the jsp was not able to compile, it gave me an error:
    ReportClientDocument.inprocConnectionString cannot be resolved
    Now my queries are:
    1. What is Report Application server(RAS)?
    2. Is it required to set Report application server in JSP page? It was not required in Crystal Reports XI. If YES, then how to configure RAS inside our applications WAR file?
    3. I am using WebSphere Application Server for deploying the WEB Archive file (WAR file). The Crystal Reports 2008  library (JARS) are embedded inside the WEB-INF/lib folder. How to specify the RAS server inside thhe WAR file? Is it some XML configuration file which we have to keep at WEB-INF level? Or we have to modify the existing CRConfig.xml file?
    4. I would like to mention here that we have bundled crystalreportviewers12/ folder in our WAR file at the same level where reports JSP pages exits.
    Thanks in advance.

  • How to connect Crystal Report 2008 server with SAP BI/BW server

    Hi Michelle,
    Older versions of CR would allow you to run CR from a network share point but you still had to have a license for each user. Current versions of CR do not allow you to do this any more, possibly using a Citrix or Terminal Server would allow this but you still need a license for each user. Older versions had a Network install option.
    And as suggested exporting to PDF or some other format is fine for end users viewing your output. They are not using CR but Adobe Reader or Word etc. to view the reports, they just can't use the Designer to view the reports.
    Hope this is clear now?
    Thank you
    Don

  • How to configure Crystal Reports 2008 and IIS7 and Windows Server 2008?

    I have downloaded and installed the trial for Crystal Reports 2008 on our Windows 2008 server.  I can open Crystal Reports on the server just fine, but I get HTTP 500 errors when I attempt to view a report hosted on that server via the web.
    As far as I can tell, the handler mappings in IIS7 are not configured properly, although I confirmed that the Crystal Reports 2008 install did add several handlers.  I read that I must configure the application pool to enable 32-bit applications.  I did that and am still getting the same error.  Documentation seems sparse and I've spent the better part of the day searching the forum here with no luck.  What am I missing?

    Don,
    Thank you for the quick response!
    We will ultimately be using ASPX/C#, but this simple case has a very basic report with no databind, just a single text label that reads "test succeeded" and I'm attempting to access it by direct URL (i.e. "http://192.168.99.21/crystalreportviewers12/test.rpt").  This works on our Windows 2000 server running Crystal Reports 8.
    I've also tested with a simple test.aspx file with only the line "Response.Write(System.DateTime.Now.ToString())" and that works just fine.  This file is in the same folder as the test.rpt file.
    If I leave the Application Pool set for the "Integrated" managed pipeline mode, I continue to get a rather generic "500 - Internal server error".  If I switch it to "Classic", I get the following error:
    Failed to Execute URL.
    Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

  • How to create crystal report 2008 with running totals?

    i want to create a report with running totals as follows:
    Balance B/F 1000.00
    Invoices     Receipts    Running B/ce
    100                            1100
                     500             600
                     500             100
    300                              400
                     400                0
    The B/F field is passed as a Parameter.

    Hi  panayiotis,
    In order to create a running total you need to have absolute clarity on the following:
    (i)Whether the running total be set on change of field/record/group.
    (ii)Whether the running total be set on change of record/group OR never.
    Make the appropriate choice.
    Apply this to the field to summarize and type of summary in Running Total Pane.
    Thanks,
    Amogh.

  • Crystal Reports 2008: Failed to load database information

    Hi,
    I have an application (windows forms) that loads a report as a ReportDocument, and prints it to a predefined printer.
    This report is drawing its data from an xml file with an xml schema, both of which have hardcoded paths in the report.
    I have built the project into an installer and have installed it on my local machine. Works great, prints fine.
    However whenever I install it on another machine (and thus deploy the redistributable) I get the following error when the user tries to print.
    CrystalDecisions.CrystalReports.Engine.DataSourceException: Failed to load database information.
    Error in File temp_b647a5f7-7ab3-4f76-8154-0063f3b2b394 {1ADFD95E-D1A2-42A9-AC96-E8DBE2B9940A}.rpt:

    Failed to load database information.
    I have narrowed the exception in my code down to the following line (which I don't think is the problem)
    LabelToPrint.Load(Util.workingDirectory + "Labels\\" + fileName + ".rpt");
    LabelToPrint.PrintToPrinter(ps.PrinterSettings, ps, false);
    Is there something that I need to set up on the users system that I don't know about? Could the system not have ODBC capability? Any help would be greatly appreciated.
    Thanks,

    What we need to do now, according to our customer's requirement is how to add a Digital Signature to the PDF report.
    The one million question is: Is there any way using Crystal Reports 2008 .NET Libraries to add a Digital Signature to a report (in its PDF version)???
    Thanks in advance for your Help

  • How to use CRAXDDRT.DLL in crystal report 2008?

    Hello All,
    We have purchased Crystal report 2008 Full software.
    We need to insert BLOB field into Crystal report 2008 at runtime using *CRAXDDRT.DLL*.
    How can I insert OLE object and bind it at Runtime using crystal report 2008?
    Is it possible to insert Ole Object runtime using crystal report 2008? If yes how and if not is there alternative to perform this job.
    Please let me know your feedback.
    Thanks

    CrxDDrt.dll is only provided in order for the Crystal Reports designer in the .NET IDE.
    1) You are not licensed to use this CraxDDrt.dll
    2) Even if you were, in previous versions of CR, there were licensing implications to using the craxDDrt.dll (read $$)
    3) Once your project would be done, using CR 2008, you would not be able to distribute the runtime as there is no CR MSM or MSI that contains the craxDDrt.dll and it's supporting runtime.
    In your original post you say:
    "I need to show Word and Pdf file in to Crystal report 2008 using CRAXDDRT.DLL";
    I do not understand why you'd need to do this using the craxddrt.dll? You should be able to insert a BLOB field using the RAS SDK for .NET and CR 2008. Now, one hting you will have to keep in mind. If you insert a multipage .doc or .pdf file into the report, you will only get the first page of that document. I suggest you try this in the CR designer first. Always remember that if you can not do a certain thing in the designer, you will not be able to do it at runtime either. Giving all the limitations above, if you are still interested in doing this using RAS, let me know and I'll set you up with some resources to get you going.

    The error invalid export DLL or export format may occur when exporting to Excel and RTF formats in .NET applications utilizing the Crystal Reports 2008 runtime (v 12.0)
    Other export formats like Adobe PDF, Crystal Reports, CSV all export with no error
    Some customers have resolved this by adding C:\Program Files\Business Objects\BusinessObjects Enterprise 12.0\win32_x86 to their environment path variables
    This may have something to do with the file libpng10.dll. Both crxf_xls.dll and crxf_rtf.dll are dependent on it.
    Thanks in advance for your co-operation. We hope to figure out what is causing this issue soon.

    Hi,
    I am also having the same problem, except that I am not using Crystal Report 2008 runtime but the actual Crystal Report 2008 installation on Windows XP SP2 with VS Studio 2005 (VC++). MS .NET Framework 2.0.
    Cyrstal Report XIR2 was installed on the same machine but uninstalled before installing Crystal Report 2008.
    So only one instance of libpng10.dll and found in C:\Program Files\Business Objects\BusinessObjects Enterprise 12.0\win32_x86
    Crpe32.dll        3/1/2008 version 12.0.0.683
    Crxf_xls.dll       3/1/2008 version 12.0.0.683
    Crxf_rtf.dll         3/1/2008 version 12.0.0.683
    crdb_oracle.dll  3/1/2008 version 12.0.0.683
    libpng10.dll       3/1/2008 version 1.0.30.0             122880 bytes
    There is no problem for exporting to pdf, html, word, csv, Crystal Report. If I create a testing report without any data from database, the testing report can then be exported also to rtf and xls.
    Oracle 11.1.0.6 is the DB for the reports.
    Adding C:\Program Files\Business Objects\BusinessObjects Enterprise 12.0\win32_x86 to the path did not resolve my problem.
    Any idea to fix this issue?
    Thanks

  • Crystal Reports 2008-Vista-ERROR-crw32.exe Entry Point Not Found in dll

    Hi Experts,
    I just installed the Crystal Reports 2008 (with SP0) on my Vista (Home) machine.  When I try to start the CR 2008, I am getting the below error message:
    Error Title: crw32.exe - Entry Point Not Found
    Error Message: The procedure entry point ?PrintLegend@CMapXLegend@CSLib300@@QAEXJJJJJ@Z could not be located in the dynamic link library cslibu-3-0.dll
    Here are the things I tried to resolve the above problem:
    1) Uninstall and Reinstall the CR 2008.  -  No change.
    2) I configured the DEP to accept Crystal Reports (Performance - Advanced - DEP allow). 
    None of these seem fix the problem. 
    Can you please help me kick start the Crystal Reports 2008? 
    Thanks,
    Arun

    Please try with this:
    Run a command prompt as administrator. From the start menu, select "All Programs", then "Accessories" and right-click on the "Command Prompt" shortcut and choose "Run As Administrator". From here you can use the following command to disable Data Execution Prevention (DEP) with the following command:
    bcdedit.exe /set nx AlwaysOff
    Keeping your command prompt open, run your setup or other process being stopped by DEP. Then, to turn it back on again, do the same and run the following:
    bcdedit.exe /set nx AlwaysOn

  • How to overcome the Memory leakage issue in crystal report 2008 SP2 setup.

    I have developed the small windows based application tool with help of  Visual studio 2008 for identify the memory consumption of crystal report object. It helps to load the crystal report objects in the memory and then released the object from the memory. The tool simply does the u201CLoading and Unloadingu201D the objects in the memory.
    The tool will be started once u201CTest_MemoryConsumption.Exeu201D executed. The u201CTest_MemoryConsumption.Exeu201D consumes u201C9768 KBu201D memory before load the crystal report object in memory. It means, 9768 KB is normal memory consumption for run the tool.
    Crystal report object initiated by the tool and object help to load the report in memory once the tool initiated the crystal report object. Now u201CTest_MemoryConsumption.Exeu201D consumes u201C34980 KBu201D memory during the crystal report object creation and report load process. The actual memory consumption of crystal report object is 34980u20139768=u201C25212u201DKBu201D. 
    The memory consumption u201C34980 KBu201D will be continued till the end of the process. The memory consumption will be reduced to u201C34652 KBu201D from u201C34980 KBu201D once report load process completed. It means, u201C328 KBu201D memory only released from the memory consumption. Tool enables the Release command for the crystal report object. But crystal report object does not respond to the command and will not release his memory consumption.
    The memory consumption u201C34652 KBu201D will be stayed in the memory once job ends.  If i again initiate the crystal report object then it crystal report object start to consume the memory from 34652 KB.
    Database objects and crystal report objects are properly used in the tool. The object release commands properly  communicated to crystal report setup. But the u201CCrystal report service pack 2u201D setup unable to respond the commands which has enabled from .Net Tool.  Crystal report objects are properly initiated and disposed in the tool. But the crystal report unable to release from the server.
    The memory consumption will be reduced once the server restarted or kill the application.
    Crystal report 2008 and crystal report 2008 SP2 setup available in the server.
    Microsoft .Net Framework 2.0 SP2, Microsoft .Net Framework 3.0 SP2 and Microsoft .Net Framework 3.5 SP1 are available in the server,
    Could you please suggesst how to avoid the memory consumption keep increasing and  how to release the memory consumption  once the crystal object disposed???

    Hi Don..
    My case is different one. I hope, the problem with Run time Installation setup file (Crystal report 2008 Serivce Pack2 installer) which we installed in the server.
    Let me explain with Live scenario which our client faced in crystal report 2008 Service pack2 Installer.
    Our client is using a application to help to print their reports. The application is developed with Windows service.
    Windows service keep on running in the server. Windows service executes the client 's crystal reports( Labels Report, Stock  report) which designed for clients need and the reports will be printed from printer. 
    10 Same type report (Label Report) will be printed in 1 minute. Reports are not printing during non business hours. But the windows service keep on running.  Memory cosumption of application will be 160 MB in business hours.
    For Example, On Monday the application memory consumption starts with 160 MB. The Memory consumption will be reached 165 MB  in peak business hours. Then the memory will be ended in163 MB in the End of Monday. It means, The memory consumption will be in 163 MB during the non business hours. Reports will not be printed in non business hours.
    On Tuesday, the application memory consumption starts with 163 MB and it will be reached 168 MB during the peak hours. The Memory consumption will be ended in 165 MB in the end of Tuesday.  The same process contiues till friday. End of friday, the memory consumption of the application will be ended with 170 MB.
    Application Memory Consumption slowly increasing in the server. In 5 days, Memory consumption reached Threshold value (170 MB) of the server. Application gets hanged up once the memory consumption reached 170 MB. We got the error messages as "Attempted to read write protected memory " / "Not Enough memory for process".  If we restart server / If we restart the service then memory consumption of application get reduced to 160 MB.
    From the above scenario, We came know that the either the problem with Application object or the problem crystal report object. In the application, We have checked dispose methods of application objects completly. I am sure that  application objects are properly disposed in the application. I hope the problem not with application objects. The problem with Crystal report objects.
    Application properly communicates the dispose methods to crystal report objects. Crystal report objects are not released from
    the memory.
    Crystal report 2008 Serive Pack 2 setup installed in the server. 
    As you said, If Crystal report runtime is not released from memory then memory consumption keep increase???  In service oriented architecture application, how to unload the crystal report runtime??
    Do you any fix for this kind of issue??
    Willl Crystal report 2008 service pack 3 help on this issue??

  • Problem with keydecoder.dll in Crystal Reports 2008 Trial Version

    Hello,

  • Alternative to craxddrt dll in crystal report 2008

    Hi,
    I have been using crystal report 8.5 where there was a control called RDC for end users to design the report which uses craxddrt dll. Now we have purchased crystal report 2008 and we have the same requirement but since RDC is not supported now,  could you please guide how to implement the logic of RDC in Crystal report 2008 with Visual Studio 2008?
    Your help will be appreciated.
    Regards,
    Vibhuti

    Hi, Vibhuti;
    It's not that the RDC is not supported with CR 2008, it does not exist. You will have to use the .NET assemblies.
    See the thread at the top of this forum for some getting started tips:
    Read Before Posting - Where to find Crystal Reports .NET SDK resources
    You can find some samples here:

  • "Invalid export DLL or export format" with Crystal Reports 2008

    I've included this sticky because we are seeing many posts in this forum regarding the error Invalid export DLL or export format when exporting to Excel and RTF in .NET applications using the Crystal Reports 2008 .NET SDK.
    Issue
    - Exporting a Crystal Report to Excel or RTF format
    - .NET application using the Crystal Reports 2008 runtime (version 12.0)
    - error Invalid export DLL or export format
    We've been doing some testing in-house and haven't reproduced this behavior. In order to figure this issue out we will need your help. If you are getting this error please reply to this post with the following information:
    - Server Operating System
    - Version of the .NET Framework
    - How did you deploy?
    - If you deployed with CRRuntime_12_0_mlb.msi - what was the date of the file and its size?
    - What is the file version of crpe32.dll on your server? You'll find this in the C:\Program Files\Business Objects\BusinessObjects Enterprise 12.0\win32_x86 directory
    - How many libpng10.dll files are on your system? List all instances.
    - Any additional comments
    What We Know
    - The error invalid export DLL or export format may occur when exporting to Excel and RTF formats in .NET applications utilizing the Crystal Reports 2008 runtime (v 12.0)
    - Other export formats like Adobe PDF, Crystal Reports, CSV all export with no error
    - Some customers have resolved this by adding C:\Program Files\Business Objects\BusinessObjects Enterprise 12.0\win32_x86 to their environment path variables. Note the system must be restarted after editing the path variable.
    - This may have something to do with the file libpng10.dll. Both crxf_xls.dll and crxf_rtf.dll are dependent on it.
    - libpng10.dll has changed versions from SP0 to SP1. In SP0 it was 1.0.30.0 and in SP1 it is 1.0.30.1
    libpng10.dll dependencies
    The dependencies have also been updated for libpng10.dll in service pack 1. This may have something to do with the export issue. If you've deployed your application with the latest merge modules or setup package for service pack 1 you'll want to make sure you have version 1.0.30.1 of libpng10.dll.
    Version 1.0.30.0
    - zlib.dll
    - msvcr71.dll
    - kernel32.dll
    Version 1.0.30.1
    - boezlib.dll
    - msvcr80.dll
    - kernel32.dll
    Thanks in advance for your co-operation. We hope to figure out what is causing this issue soon.

    Our company has also been experiencing this issue with deployed versions of our software, and during my examination of the error I have made the following discoveries:
    For us the error has only been reproduced on Windows 2003 running Citrix
    The error does not occur on Windows XP, Windows 2003 or Vista without Citrix
    For installation of our application we use the CRRuntime_12_0.msm merge module (version 12.0.0.683, file size 46790KB)
    As mentioned in the first post this error is related to the files crxf_rtf.dll and cfxf_xls.dll being unable to locate its reference to the file libpng10.dll during load.
    I have run the application with ProcMon (http://technet.microsoft.com/en-us/sysinternals/bb896645.aspx) attached on both environments that work correctly and that does not work and iIve made these observations:
    During load of dlls Windows searches for references in the following orders (see http://msdn.microsoft.com/en-us/library/ms682586.aspx):
    1. The directory from which the application loaded.
    2. The system directory.
    3. The 16-bit system directory.
    4. The Windows directory.
    5. The current directory.
    6. The directories that are listed in the PATH environment variable.
    Looking at the ProcMon log for the environment where it works correctly (Windows XP, no Citrix) it looks like this . Numbers represent the search order mentioned above:
    Load Image     C:\Program Files\Business Objects\BusinessObjects Enterprise 12.0\win32_x86\crxf_rtf.dll     SUCCESS     Image Base: 0x3e640000, Image Size: 0x79000
    (1) QueryOpen     C:\Program Files\<our application name>\libpng10.dll     NAME NOT FOUND     
    (2) QueryOpen     C:\WINDOWS\system32\libpng10.dll     NAME NOT FOUND     
    (3) QueryOpen     C:\WINDOWS\system\libpng10.dll     NAME NOT FOUND
    (4) QueryOpen     C:\WINDOWS\libpng10.dll     NAME NOT FOUND     
    (5) QueryOpen     C:\Program Files\Business Objects\BusinessObjects Enterprise 12.0\win32_x86\libpng10.dll     SUCCESS      ...
    So you can see it finds the file in the "current directory"
    Now, from the environment where it does not work (Windows 2003 Server / Citrix):
    Load Image     X:\Program Files\Business Objects\BusinessObjects Enterprise 12.0\win32_x86\crxf_rtf.dll     SUCCESS     Image Base: 0x3e640000, Image Size: 0x79000
    (1) QueryOpen     X:\Program Files\<our application name>\libpng10.dll     NAME NOT FOUND     
    (2) QueryOpen     X:\WINDOWS\system32\libpng10.dll     NAME NOT FOUND     
    (3) QueryOpen     X:\WINDOWS\system\libpng10.dll     NAME NOT FOUND     
    (4) QueryOpen     X:\WINDOWS\libpng10.dll     NAME NOT FOUND     
    (5) QueryOpen     X:\Documents and Settings\<my user name>\WINDOWS\libpng10.dll     NAME NOT FOUND     
    (6) QueryOpen     ... loops trough all paths in the PATH variable, finding nothing
    As you can see somehow the current directory is %USERPROFILE%\WINDOWS and not the Crystal Reports bin path in this environment at the time of loading the dll.
    I have yet to discover why this is the case, but i tought i could share what I have found =)
    The %USERPROFILE%\WINDOWS folder is not a standard Windows folder, and I think it is used by Citrix for some files (like win.ini)
    This also shows why adding the bin folder to the PATH variable is a valid workaround for some, but for us this is not really a good solution as we need this to work out of our installer. We don't always have consultants do the installations for the customers and we cannot expect them to manually edit the PATH variable, and we don't want to add to the PATH variable in the installer unless this is the only way...
    So, I hope this maybe can bring you closer to being able to reproduce it. I'm still looking into it, will post more if I find something else interesting
