use RDC in ASP.NET

[Former Member]

I have a Classic ASP application using Crystal Reports 8.0. It is using the ActiveX Viewer to display the reports on IE. It is working just fine.

But, I want to covert it to use ASP.Net on VS 2005. I don't want to rewrite the whole structure with new Crystal Reports version with RAS...etc. I simply want to modify all of my ASP codes to ASP.Net, then continue to use the Crystal Report RDC components, and continue to use the ActiveX Viewer.

I am thinking I will have to manually rewrite the rptserver.asp and SmartViewerActiveX.asp files into aspx files.

Is this possible? Has anyone done this successfully? Or is there an easier solution?

Hi Paul,

The RDC is not supported nor has it ever been tested in .NET. If you do use it SAP can't help you, I've heard of some developers doing it successfully but most eventually run into problems. So you may be able to get the app to work on your DEV box but when deploying you'll likely have problems that we don't have a solution for.

Also be aware that as of CR 9 the RDC was changed, the old log on methods and Parameters API's have been replaced with updated methods. And CR 9 and above will read old reports but you cannot save them in CR 8.5 or lower formats, once saved they will no longer open in CR 8.5 or lower.

The RDC has now been completely deprecated and as of CR 2008, it's no longer shipped but still available in CR XI R2 ( 11.5 ) but it's end of life is this June.

You can get complete CR functionality now, everything but the standalone Report Designer, with VS 2010. See this [link |http://www.sdn.sap.com/irj/sdn/crystalreports-dotnet]for downloads and more info.

Also, CR for VS 2010 is the only version of CR supported in VS 2010, meaning no escalation path to get any older versions of CR fixed.

Thank you
