32bit and 64bit Apps using Crystal 2010sp1 with a recordset

Question

Hi
I'm using Crystal 2010sp1 with VS2010. I have some code that I did not write, which obtains a recordset and passes that to the ReportDocument. It then goes on to .Export() the report.
When my app is compiling as 32bit the .DataSourceConnections on the ReportDocument contains 1 item with the following properties:
DataBaseName=""
DBConnHandler=0
IntegratedSecurity=False
LogonProperties = { "ADO.Net DataSet Object", "0,4AFECC" }  { "ADO.Net DataSet Object", "0,4AFECC" }
{ "Internal Connection ID", "2e3b2f7f-0c31-472a-9773-f301a7ba9a3e" }  { "Internal Connection ID", "2e3b2f7f-0c31-472a-9773-f301a7ba9a3e" }
Password = ""
ServerName = "NewDataSet"
Type = CRQA
UserID = Nothing
And it exports perfectly!!
When compiled as "Any CPU" and running on a 64bit machine, the properties are:
DataBaseName=""
DBConnHandler=0
IntegratedSecurity=False
LogonProperties = { "Field Definition File", "BL_Extras.ttx" } { "Field Definition File", "BL_Extras.ttx" }
Password = ""
ServerName = "D:\EntaV4\ENTAReports\rpt\BL_Extras.ttx"
Type = CRQA
UserID = Nothing
And the export fails with the exception:
"Failed to load database information. Error in File BL_Extras {9D634275-70C4-42E8-B7EE-C2A69C0CDD2B}.rpt: Failed to load database information."
Why under 64bit is Crystal setting different connection details? And where is it getting the path for the ttx file in the ServerName property, my app and report are on my C drive in a totally different location. That folder on D had never existed on my machine.
I do happne to have the ttx file for this report, but putting it next to the rpt or in the above path makes no difference. I don't have the ttx for other reports though anyway and running as 32bit it works even if I delete the ttx though.
I have searched the error and found several pre-SP1 and non-recordset scenarios. I also read a little about create XML files for the reports but that is going to be too much work as there are hundreds of reports. It's not a lack of a 64bit ADO driver is it?
I thought i'd ask here for other solutions before I step back in time 10 years and make this app 32bit only.
I'm pretty sure this all worked on 2008 with CR2008.....

I exported the data as XML from my datatable like you said. I did it both running as x64 and x86, the output was the same.
I thought i'd eliminate any bad code that might be in my main app by writing a little test app that loads that xml and drops it in a viewer control. I started a new project in VS, added a form with the Crystal Report viewer. I then wrote code to load the rpt file, and read the xml into a dataset, and then setdatasource on a report object to the first table of that dataset (which is what my main app is doing).
Dim crReportDocument As New ReportDocument
Dim filePath As String
Dim ds As DataSet
filePath = "c:\64crystal.xml"
ds = New DataSet()
ds.ReadXml(filePath)
crReportDocument.Load("C:\inetpub\wwwroot\SchedulerManager\rpt\BL_Extras.rpt")
crReportDocument.SetDataSource(ds.Tables(0))
CrystalReportViewer1.ReportSource = crReportDocument
Running it in x86 I am prompted for some parameters that the report required, and then the report renders in the viewer perfectly, no problems.
Running this app in x64 prompted me for the parameters, and then I get a msgbox saying:
Failed to load database information
Error in File BL_Extras {CD6C5C52-744C-433E-9297-87ECC3834262}.rpt:
Failed to load database information.
So then going back to what you asked, I went to the viewer control and click 'choose a crystal report' I get a 'Bad forumula result' error. If I select 'Create a new Crystal Report' and then 'From and existing report' and select the rpt file i'm working with. It then shows the rpt file in the VS designer with all the fields and sections and looks fine, though returning to the viewer gives the 'Bad Formula result' again. Seem to get this on several reports so am assuming its just because there is no data yet.
On this report now in my project I went to set datasource location and selected the XML it then shows NewDataSet with Table under it in the treeview. The update button is disabled if i select the table. If I select the dataset and click update it tells me:
"Some tables could not be replaced, as no match was found in the new data source. Please specify the table required for any unmodifeid tables". The top pane of this window is showing the file details of the ttx that it thinks is located on the D drive.
If I go to database expert and move the table over it then prompts me to find the ttx file. It doesn't let me skip this so I give in and tell it where it is. I then get the link tab. It shows the ttx with 23 fields and my xml table with 27 fields. It has 11 fields linked automatically,
A comparrison of the ttx and XML in notepad shows the following, the bold fields are the ones that did not auto link.
DateOption, ttx:Number, xml:unsignedByte
StartDate, ttx:dateTime, xml:dateTime
EndDate, ttx:dateTime, xml:dateTime
VenueGroups, ttx:Memo, xml:string
Profiles, ttx:Memo, xml:string
Users, ttx:Memo, xml:string
Extras, ttx:Memo, xml:string
RepGrouping: ttx:Number, xml:unsignedByte
IncludeDiscount, ttx:Number, xml:unsignedByte
VgrDescription, ttx:String(50), xml:string
CurSymbol, ttx:String(3), xml:string
CurName, ttx:String(30), xml:string
CurScaleFactor, ttx:Number, xml:short
ProDescription, String(50), xml:string
UseName, String(30), xml:string
TransactionDate, ttx:Datetime, xml:dateTime
StxCode, ttx:Number, xml:int
StxDescription, ttx:String(100), xml:string
MrwID, ttx:String(3), xml:string
MrwDescription, ttx:String(100), xml:string
Sales, ttx:Number, xml:int
Returns, ttx:Number, xml:int
Reserved, ttx:Number, xml:int
GrossSalesAmount, ttx:Currency, xml:decimal
GrossReservedAmount, ttx:Currency, xml:decimal
SalesVAT, ttx:Currency, xml:decimal
ReservedVAT, ttx:Currency, xml:decimal
Right clicking on all of these bold items on the table side (in the link tab) says that those bold fields are type Number. So not sure why the first 8 don't link as they are looking for Number. As for the last 4, in SQL these fields are type money, once read by vb.net into a datatable they are of type decimal. Not sure what crystal is expecting here.
I can manually link the 8, but it tells me for the 4 currency fields that the "data types are not compatibile"
I still don't get why if running as 32bit and passing the datatable from xml or sql to the rpt, even without the ttx, works without issue.
I think for now that i'm going to have to simply compile my main app for 32bit, but would still like to understand what is going on here. Thanks for helping to look into this.
Tony.
