I have a VB6 app which connects to either a SQL Server or Oracle Database. It includes some Crystal Reports, made with an old version (CR 8.5).
I'm working on upgrading the Crystal viewer to CR 2008 (using Interop Forms Toolkit).
Everything is working fairly well, but I am seeing a few reports which are painfully slow to appear. Other reports are perfectly fine.
I would appreciate any tips for things to look at that would cause a crystal report to appear quickly in the CR 8.5 preview window, but slowly in the CR 2008 preview window.
The most recent Crystal reports version supported by VB6 is Crystal XI. I know that you can create a COM object in .NET and call it from VB6 , but this will not change the fact that Crystal 2008 is not supported. Sooner or later you will hit a report where the VB6 app will have issues, which you cannot resolve . To check if this is the case for the current reports create a temp .NET project and run one of them. If the report works fine obviously the issue is VB6. Of course there might be other reasons for the slow reports. Did you change the machine where you are running them ? If yes , do you have the same printers installed and the same drives (including mapped drives) on the new machine?
P.S. Actually to test the report in .NET you don't need to create a project. It will be easier if you download one the existing .NET Crystal viewers on the market. Usually they have trial mode , which will be enough for your test. Let me know if this will work better for you , I can post some links
Here's something that vastly sped up the processing (previewing or printing of the reports):
Open the report in the Crystal 2008 editor
Database menu, select "Verify Database"
Save
Doing that changed some fields from "PersistentMemoField" to "StringField", and removed some "DatabaseName" values. Anyway, I'm happy with the results.

I am working on Visual Studio 2010 , developing a windows app.
I want to create some simple reports. I am confused about which reports should I use in the application.
The reports which are available in the Visual Studio or the crystal reports.
what are the advantage of report over each other ?
I am working on reports after long time so, can I get some simple links, so I can understand workflow of it.
Crystal Reports seems well documented, more ressources available than Microsoft Reporting
Huge API in CR (just try to print a Microsoft Reporting-report without preview, that's ridiculous!)
Crystal Reports somehow slower than Microsoft Reporting with huge amount of data
Designing reports against custom BusinessObjects is really worse (Wizard isn't even able to "see" objects in another project!) in Crystal Reports
Crystal Reports's preview integration into our apps is much better than in Microsoft Reporting (just try to make your own toolbar!)
Microsoft Reporting's integration in the dev environment is superior to CR (which's habit to implement it's own DB-connection is bad taste)
Both seem to lack designers, our users can use at runtime from within our apps (not external!) to manipulate reports which we prefer to store in the DB (seems to be quite easy with Microsoft Reporting as it's only XML to be stored!) for better managability and deployment.
We have recently upgraded to windows 7 and have noticed that there are compatibility issues with my previous version of MS visual Studio 2005.
From taking a look around the web I believe that this issue is due to SP1 for Windows 7. My organisation will not get rid of SP1 just for one or two developers so I need to figure out a work around.
This is the issue...
I have an old MS visual studio website that has a report located on the home. This report was created in MS VS 2005.
Other versions of Visual Studio in have are 2010 and 2012. I have tried to convert the 2005 report into 2010 and this does state that it has been converted but I still cant open or do anything with the report. My 2005 web site is too large to convert or move into 2010 and we can still maintain this 2005 site by opening this up in 2010. It just seems to be a problem with the 2005 report.
I'm running out of options to make a simple change to a report. Anyone else got any ideas? I have even tried to create this report in 2010 and then add this to my 2005 site but this doesn't work.
Regards
Betty.
You say a report and then say that it is a whole site? Why not run a second site in tandom? Make a whole new site and name it differently like
http:// (servername)/Reports2012
Then put reports there. You cannot open a converted report in a site that is for a prior version, you can view it in Microsoft Business Intelligence Studio, BIDS, which is an add on to Visual Studio. If you can upgrade but cannot view it there, there is something wrong with the language file potentially. I would then make a copy of it in the old 2005 BIDS, then take that copy and see if you can upgrade that and if it will work. If that STILL does not work you could make a test report in BIDS 2010(SQL 2012 works on VS 2010, yes weird but true) to assure you can create reports there. Many times people try to open SQL Server 2012 Reports on VS 2012 and it won't work. You need 2010 add on you can find it under All Programs>MS SQL Server 2012>SQL Server Data Tools(They made the naming very confusing as it opens up and display BIDS, but calls itself 'Data Tools' under the programs). Every other version of SSRS lines up with that year of SQL Server to that year of VS. Not 2012.
If the report upgrade still does not work, yet you can create a run a new report fine; I would suggest potentially opening up the file dircectly. Your projects in a Reports solution generally have a file '(something).rdl' that RDL is the actual file and is just XML markup of the language. This is a last resort as you are essentially trying to do manually what the upgrade is failing to do in the xml. You merely copy a working report, and then paste the parts of the old report into their correct sections. Ensure the XML is valid as well.
If you cannot manage that to work you will need to recreate the report from scratch.
We are developing an application which generates reports in .rpt format. When we open the various types of report using Crystal Report Viewer 2011 all of them work fine except for one, which causes Crystal Report Viewer to crash ( - [Internal Error DataViewL573] ).
The application is built with Visual Studio 2005. The reports are generated with the Crystal Decisions plugin.
I have two reports; One that loads fine in the Viewer (GOOD.rpt), and one that causes it to crash (BAD.rpt).
Does anyone know of any quick avenues of investigation outside of taking apart the report construction process itself? Are there any known issues with the viewer that I should be aware of?
Cheers,
Lordmonkey.
It is probably a "corrupted" report. Not all Crystal runtime engines are created equal.
See this KB article:

I have some issues with my reports since I have updated them to VS2010 format.
Even though I have modified references to from v9 to 10 for Microsoft.ReportViwer.Common and Microsoft.ReportViewer.WinForms as well, when I try to type code. in a field, what is after "Code." is always underlined with red and I get #ERROR instead of the value I want when I print the report. I know it is case sensitive and I double checked the spelling multiple times.
Moreover, I don't know why but I have errors with the Fields! syntax; I seem to have to use the Fields().value to get them to work (at the places I don't need to call custom code too)
These reports worked well before conversion (over 20 reports converted this way) but do not now. Seems like custom functions are not "seen" by the report designer. I tryed to make them public, shared; all I had is the same stupid #ERROR display.
I want them to work in VS2010 to avoid always having to modify them in VS2008 and then go back in VS2010
It's a winform application with framework 3.5
Any idea of what could cause that and what is the remedy?
Many thanks
Nico
There are a couple of ways to use custom code in SSRS. Firstly you can enter VB directly into the window under
Report -- >Report Properties --> Code
Another way is to write a custom DLL (which can be done in any .NET language of course), which then needs to be copied to both your dev machine and the production report server.
You then need to create references to that assembly in the project using:
Report --> Report Properties --> References (I assume you know this).
If you are not using your own custom assembly, and just using a reference to one on your machine then there could be some confusion on the server as to where to find the dll's. You may need to copy DLL's to the folder as indicated in the KB link below:
http://support.microsoft.com/kb/920769
When you drag a field onto a tablix or textbox, and have a look at the value expression, does it use the Fields!Fieldname.Value syntax? That syntax is natural to SSRS so it sounds like something seriously broken in your visual studio 2010 there if that is not working. I take it you installed visual studio 2010 to create web applications. What you haven't explained is which version of BIDS or SSDT you are using. If you are developing reports for SSRS 2008 R2 or earlier, then these are not compatible with visual studio 2010. There's no compromise there.
If you are developing for SSRS 2012, then you are using either SSDT by itself (which installs a shell version of visual studio 2010) OR if you already have visual studio 2010 then you need to install service pack 1 for VS2010 and then install SSDT from the SQL Server 2012 disc.

I just made the move to Visual Studio 2010 from 2008 and I guess I didn't do enough research before I moved. I seem to have gotten myself in quite a bind.
I knew Crystal Reports was no longer a part of 2010 but the beta was downloadable. I followed this document for deployment. My only change to this document is on the bindingRedirect element I changed the newVersion attribute value to 10.5.3700.0 because that is what is in the GAC and what was in the manifest of my 2008 project.
Unfortunately this is not working. Whenever I try to run a crystal report I get the exception :
An error has occured while attempting to load the Crystal Reports runtime.
Either the Crystal Reports registery key permissions are insufficient or the Crystal Reports runtime is not installed correctly.
At this point I think I am going to have to roll back and go back to VS 2008 until SAP comes out with a runtime. I can't believe there is not a work around for this as it will break so many projects that have Crystal Reports included in them.
Has anyone been able to work around this? If so, how?
Download the required package from here, install it and it will work,
Crystal Report Runtimes
