CR RDC 11.0 vs 11.5

Question

We are using the Crystal Reports RDC 11.0 in our application developed in Powerbuilder, but now a customer needs to have the 11.5 version installed and this is causing some problems.
I get errors when I try to connect to the database and when trying to set the reportsource on the viewer control.
oleCrystal.LogOnServer("crdb_oracle.dll", ls_Server, '', ls_user, ls_pw)  //Connecting to databse
this.object.ReportSource = l_oleReport //Setting the reportsource.
Both of these works fine with 11.0. What are the equivalents in 11.5 and where can I find the documentation for the 11.5 version of the RDC?
Alternatively, is it possible to have both viewers installed and connect to 11.0 specifically?
Thanks in advance.

Jan Erik

I'll break the reply into two post as it is a bit lengthy and these posts loose formatting after 1000 chars or so.
.LogOnServer is a method that was deprecated in CR 8.5. So, the further away from 8.5 you go, the less reliable it is. From CR 9 on, you should be using the connection properties bag. See [this|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/00635998-751e-2b10-9cba-f50ee1e4ef81] article and the help files for CR XI or CR XI r2 for more details.
It is never a good idea to have CR XI and CR XI r2 on the same box. In this case I do not think it is the crviewer dll that is the issue, rather it is the craxdrt.dll.
You should be able to use prog ID to specify the version of crviewer and craxdrt you want to load. Something similar to [this|http://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes_boj/sdn_oss_boj_erq/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes.do] note.
I also have the follwoing from an old CR Kbase:
How do you add a Crystal Report Viewer to a Visual Basic form at runtime?
The following code demonstrated how to add a viewer at runtime, set the reportsource and view the report.
Dim Report As New CrystalReport1
Dim crViewer As Object
Private Sub Form_Load()
'Create and add a version 8.5 Crystal Report Viewer.
Set crViewer = Me.Controls.Add("CRViewer.CRViewer";, "crViewer")
'Create and add a version 9 Crystal Report Viewer.
Set crViewer = Me.Controls.Add("CRViewer9.CRViewer";, "crViewer")
'Create and add a version 10.0 Crystal Report Viewer.
Set crViewer = Me.Controls.Add("CrystalReports10.ActiveXReportViewer.1";, "crViewer")
With crViewer
.Visible = True
.ReportSource = Report
.ViewReport
.Zoom 100
End With
End Sub
Private Sub Form_Resize()
With crViewer
.Top = 0
.Left = 0
.Height = Me.ScaleHeight
.Width = Me.ScaleWidth
End With
End Sub
