Error:When adding RDC runtime library (Crystal report XI R2) to Lotus notes

Question

Background : We have reporting feature implemented in one of lotus notes application using crystal reports 6 (OCX) and as Crystal report is going to be upgraded to CR XI version in my organisation, we need to implement the same using RDC component available in crystal XI . we have installed Crytal report XI R2 - SP 6 version for testing the integration.
we are  referring a document available on SAP web site(attached below) that illustrates the steps required to integrate the Crystal Reports®  Report Designer Component into a Lotus® Dominou2122 application.  http://www.sdn.sap.com/irj/boc/go/portal/prtroot/docs/library/uuid/509b02de-a81e-2b10-f598-822b6d6f2024?quicklink=index&overridelayout=true
Steps which have been outlined for adding runtime library in lotus domino application is shown below:-
1. In Domino Designer, add a Form to the application.
2. In the programmeru2019s pane, go to the (Declarations) handler of the Form and enter:
   Dim App As Variant,    Dim Rep As Variant
3. Select Create | Object and select the u201CControlu201D radio button in the u201CCreate Objectu201D dialog box that comes up. From the list of controls, select u201CCrystal Report Viewer Control.u201D This adds the control to the Form.
4. Click on the control and select Edit | Properties. In the u201CAppletu201D properties dialog, select the u201CSize object to fit windowu201D radio button and then close the properties dialog.
We are getting an error message while trying to add 'Crystal Report Viewer Control' control (illustated in Step 3 above) in the lotus notes form . Error message which we get is 'An error has occured while processing a request on an object'.
Alternatively , we created the object of Crystal Report Viewer on lotus notes form by adding viewer object file (Crviewer.dll) from the file system  after selecting the u201CObject from a fileu201D radio button in the u201CCreate Objectu201D dialog box and added following code in the postopen event of lotus notes form .
Set m_Viewer = Source.GetObject("Crystal Report Viewer Control")
Set App = CreateObject("CrystalRuntime.Application")
Set Rep = App.OpenReport(u201Cc:lotus
otes
ep.rptu201D)
Set m_Viewer.ReportSource = Rep
Again, when lotus notes form is opened , it gives error 'Variant does not contain object' at 'Set m_Viewer.ReportSource = Rep' .
Can any one suggest us any workaround or if iit is not possible in CR XI R2 into a Lotus® Dominou2122 application. Also, can any one provide us sample code if CR 2008 version can be integatred with lotus notes.

Answer 1

I believe, Lotus was never a "supported" development platform, though it did work - at one time or another. Eventually it did not and you are at that point. I think it was CR 10 where it started to be impossible to add the viewer to Lotus. This was never fixed and we never did find out if this was a Lotus thing or a CR thing.
Re. CR 2008 and Lotus. The RDC has been retired in CR 2008, so no luck there either for you. The only SDKs available in CR 2008 are for .NET and Java.
