Upgradting from CR9 (VS2k2) to CRXI R2 (VS2k5)

Question

I'm in the process of upgrading our application from CR9 to CRXI R2.  At the past I was able to create an MFC class from the actual ActiveX viewer and thus able to create an instance of the viewer on my dialog.  I'm attempting to do the same thing with the new version of the CRViewer ActiveX component but no such luck (no interfaces available in the "Crystal ActiveX Report Viewer Control 11.5<1.0>" control).  I then attempted to add the same control Crystal ActiveX Report Viewer Control 11.5<1.0> on a new dialog and when I right-click to create a variable for the viewer control I get the error message "Extender Provider failed to return an Extender for this object."
Hope I made my self clear and thank you in advance for your response.
Sorry I added the question in the wrong forum. Please disregard this posting as I will repost it in the correct forum.  Thank you.

Answer 1

Not sure if this will help, but this is an internal tip I've stored since version 10 of CR:
how do you upgrade an RDC cpp app to v10?
1) Open project
2) go to Resource View and open your dialog with the crystal report viewer
3) Delete the old viewer. If your computer only has version 10, this will show up as a blank activeX control, you may have also received an error message when you loaded the project 'activeX control could not be instantiated'
4) Right click on the dialog and select 'insert activeX control'
5) Select the Crystal ActiveX Report Viewer Control 10
6) Resize the control how you would like
7) Right click on the dialog and go to the class wizard.
8) Select the 'member variables' tab.
9) Delete the existing Viewer member variable. It will have the Control ID IDC_CRVIEWER1 or something similar. You can also check the type: CCrystalreportViewer9 or CCrystalreportViewer depending on the previous crystal report version you were using.
10) Select the Control ID for the new viewer and add a member variable for it. It will tell you it needs to generate a c++ wrapper for it. Allow it to do this. You will need to name the variable.
11) If you selected a different variable name than you were using originally, you will need to update the references to the viewer
12) you must import the new craxdrt. IE:
#import "c:\program files\crystal decisions\report designer component\craxdrt9.dll"; no_namespace
becomes
#import "c:\program files\common files\crystal decisions\2.5\bin\craxdrt.dll"; no_namespace
Only thing to watch for on the above; step (12) the file path would be "c:\program files\business objects\common\3.5\bin\craxdrt.dll";. Oh, and of course, line (5) changes to Crystal ActiveX Report Viewer Control 11.5
