Just trying to do a basic crystal report and viewing it with dynamic
sql server database but dont no what i'm doing wrong? I am using
integrated security.
Dim myRpt As crpt1 = New crpt1 'Where crpt1 is an existing crystal
report
'set databse interaction with crystal
Crystalviewer1.LogOnInfo.Item(0).ConnectionInfo.Da tabaseName =
"mySQLDatabaseName"
Crystalviewer1.LogOnInfo.Item(0).ConnectionInfo.Se rverName =
"mySQLServerNAme"
Crystalviewer1.ReportSource = myRpt
Hi,
use a dataset like this:
http://support.businessobjects.com/c...etdatasets.pdf
or in a ReportInit like this:
Private Sub ReportInit(ByVal blRefreshLocation As Boolean)
Dim crSections As Sections
Dim crSection As Section
Dim crReportObjects As ReportObjects
Dim crReportObject As ReportObject
Dim crSubreportObject As SubreportObject
Dim crReportDocument As ReportDocument
Dim crSubreportDocument As ReportDocument
Dim crDatabase As Database
Dim crTables As Tables
Dim crTable As Table
Dim crTableLogOnInfo As TableLogOnInfo
Dim crConnectioninfo As ConnectionInfo
Dim myArrayList As ArrayList = New ArrayList
'declare an instance of the report and the connectionInfo object
crReportDocument = New ReportDocument
crConnectioninfo = New ConnectionInfo
crReportDocument.Load(mstrReportName)
'pass the necessary parameters to the connectionInfo object
With crConnectioninfo
.ServerName = mstrDBServerName
.DatabaseName = mstrDataBaseName
End With
'set up the database and tables objects to refer to the current
report
crDatabase = crReportDocument.Database
crTables = crDatabase.Tables
'loop through all the tables and pass in the connection info
For Each crTable In crTables
crTableLogOnInfo = crTable.LogOnInfo
crTableLogOnInfo.ConnectionInfo = crConnectioninfo
If blRefreshLocation Then
crTable.Location = mstrDataBaseName & ".dbo." &
crTable.Location.Substring(crTable.Location.LastIn dexOf(".") + 1)
End If
crTable.ApplyLogOnInfo(crTableLogOnInfo)
Next
'set the crSections object to the current report's sections
crSections = crReportDocument.ReportDefinition.Sections
'loop through all the sections to find all the report objects
For Each crSection In crSections
crReportObjects = crSection.ReportObjects
'loop through all the report objects to find all the subreports
For Each crReportObject In crReportObjects
If crReportObject.Kind = ReportObjectKind.SubreportObject
Then
'you will need to typecast the reportobject to a
subreport
'object once you find it
crSubreportObject = CType(crReportObject,
SubreportObject)
'open the subreport object
crSubreportDocument =
crSubreportObject.OpenSubreport(crSubreportObject. SubreportName)
'set the database and tables objects to work with the
subreport
crDatabase = crSubreportDocument.Database
crTables = crDatabase.Tables
'loop through all the tables in the subreport and
'set up the connection info and apply it to the tables
For Each crTable In crTables
With crConnectioninfo
.ServerName = mstrDBServerName
End With
crTableLogOnInfo = crTable.LogOnInfo
crTableLogOnInfo.ConnectionInfo = crConnectioninfo
If blRefreshLocation Then
crTable.Location = mstrDataBaseName & ".dbo." &
crTable.Location.Substring(crTable.Location.LastIn dexOf(".") + 1)
End If
crTable.ApplyLogOnInfo(crTableLogOnInfo)
Next
End If
Next
Next
crystalReportViewer.ReportSource = crReportDocument
End Sub
