VB.NET 2008 and Crystal Reports

I'm writing a small app in vb.net 2008 Pro that executes a crystal report that was created in Crystal XI. This report has several subreports all of which use the same stored procedure that is used in the main report. I can run this report without issue through crystal but when trying to execute it through vb.net code, I receive the following error:

This field name is not known.
Error in File C:\..........
Error in formula <Record Selection>.
'({group_plan_renewals;1.PROD_CD} like '*' & 'Dental' & '*' or
'
This field name is not known

I can tell which subreport this is referring to, so I tried removing that subreport to see if it would then run, but it just goes on to the next report and lists the same error for the first line in the record selection formula. I'm stumped. Any insight is greatly appreciated.

I do not have any code to post because this error isn't triggered until after the the function to load the report is done... if there is code that you need to see that would help, please let me know. This really seems more like an issue with the report/subreport though.

How exactly are you executing it?.. proc.start?
or loading it in a report document?.. If loading in a report document, try this

report.Load(ReportType, OpenReportMethod.OpenReportByTempCopy)

I'm not sure I understand... I have a separate form in my application with the report viewer component on it. I just use the following code from my main form to load the report:

        objForm.ViewReport("\\atlas\d atlas\Dept\IT\Reporting\Crystal\11.0 Copied Designs\Health Plan Renewal.rpt", , "@Begin_dt=" & begin_dt & "&@End_dt=" & end_dt & "&acct_mgr=" & am & "&ben_anal=" & ba & "&Name=" & group)
        objForm.Show()
 
 
 
Here is the code behind the report viewer form:
 
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Partial Class frmViewReport
    Inherits System.Windows.Forms.Form
 
    'Form overrides dispose to clean up the component list.

        Try

Wait... I see what you mean. Unfortunately that didn't work. Here is the code that I used after your suggestion:

Try

objReport.Load(sReportName, CrystalDecisions.Shared.OpenReportMethod.OpenReportByTempCopy)

intCounter = objReport.DataDefinition.ParameterFields.Count

I ran into the same problem several years ago.. try this... it has always worked well for me.

Dim CR As New ReportDocument
        Dim strReportPath As String = "\\...."
        CR.Load(strReportPath)
        '
        ' Declare the parameter related objects.
        '
        Dim crParameterDiscreteValue As ParameterDiscreteValue
        Dim crParameterFieldDefinitions As ParameterFieldDefinitions
        Dim crParameterFieldLocation As ParameterFieldDefinition
        Dim crParameterValues As ParameterValues
        '
        ' Get the report's parameters collection.
        '
        crParameterFieldDefinitions = CR.DataDefinition.ParameterFields
        '
        ' Set the first parameter
        ' - Get the parameter, tell it to use the current values vs default value.
        ' - Tell it the parameter contains 1 discrete value vs multiple values.
        ' - Set the parameter's value.
        ' - Add it and apply it.
        ' - Repeat these statements for each parameter.
 
        crParameterFieldLocation = crParameterFieldDefinitions.Item(0)
        crParameterValues = crParameterFieldLocation.CurrentValues
        crParameterDiscreteValue = New CrystalDecisions.Shared.ParameterDiscreteValue
        crParameterDiscreteValue.Value = txtCpar.Text.Trim
        crParameterValues.Add(crParameterDiscreteValue)
        crParameterFieldLocation.ApplyCurrentValues(crParameterValues)
        'CR.PrintToPrinter(1, True, 0, 0)

Where would I put the connection info for the report with this code?

ASKER

Please ignore my last comment. I figured it out... however, I'm back to receiving the same error as in my initial post. Any other ideas?

mpeaden2

I use integrated security...

see code snippet.
this also works for me.. may spark some new ideas for you


Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        myConnectionInfo.DatabaseName = "XXXXX"

        setDBLOGONforREPORT(myConnectionInfo)

Thank you. This is actually what I'm already using for the connection info. It doesn't seem like the error I'm receiving has anything to do with the connection. I could be wrong though. I'm open to trying anything at this point.

Ar eyou using the CR XI dlls or the ones that come with VS 2008 for Crystal?

I'm using what came with VS 2008. I'm wordering if I maybe add the existing crystal report to the project... if that will make a difference. I'm thinking that it won't but I suppose it's worth a try. It's just odd that it's saying the field doesn't exist and it's referring to just a normal field in the stored procedure in the sub-report... not a parameter or anything.

mpeaden2

If you haven't already tried.. I would create a simple test report without any stored procs and test stored proc with the code you are using and see if you get the same error. And build from there until you pinpoint the problem..

pcareWI

ASKER

Thanks... I'll try that. I have a feeling it has to do with the sub reports. I'm going to just try removing all of the sub reports first and see if just the main report runs. I'll post with the results.

Thanks.
