Suggested Path for VB6 migration for CR

[Former Member]

Hello,

We have and old legacy app, parts of which were developed in VB6 and are now undertaking a tech stack modernization effort.  We are using the VS2008 VB upgrade to to upgrade to VB.NET with .net 3.5, then upgrading that to VS2013 and .net 4.x.  The app had also utilized Crystal Report ( version 6!) via some wrapper classes around calls to the CRPE32.DLL to run our reports.  Since we have not upgraded CR in so long, I am not even sure what the current API interface is.  I know there are .net classes, but is direct DLL API still supported?  I am in need of determining the least painful way to get our CR VB code modernized.  Any suggestions are appreciated.  Note that I would prefer to get something working under VS 2008 first.

Thanks,

Leor

That did not answer my question, and I am not looking for outsourcing services, but thanks.

Hi Leor,

As Ido mentioned, RDC COM SDK for VB development is completely deprecated from CR 2008 onwards and now there is only .NET and Java SDK.
There is no migration / upgrade path for RDC App to CR .NET, you would need to rewrite the same logic using CR .NET APIs.

The .NET SDK is almost the same for CR 2008 and CR for VS 2013 so you could directly develop your app for .NET 4.0 if you wish to. See below page which for the CR for VS 2013 downloads and the SDK developer and API guides.

Thanks,

Thanks for the update!  So which was the last version of CR that supposed the CRPE32.DLL?

Is there any SAP docs on migration from the crpe32 api to the .net api?

I wouldn't call it support for CRPE32.dll because the dll still exists in CR installation its just that it is no longer licensed to be used for direct development (does not provide any APIs).

Its the RDC COM SDK that's deprecated from CR 2008. Last version supported with RDC was CR XI R2.

Again, there is no migration path from RDC to .NET. You would have to rewrite the same logic in .NET using SDK assemblies.

See below KB

The other developer resources are here:

If you could post specific queries of what you want to achive with .NET SDK, we could possibly point you to sample applications download.

Thanks,

To reply to your question, the last version to support crpe (print engine APIs) was 8.5 (released in about 1998), support terminated about 2004.

Neither the CRPE nor the RDC are supported in .NET.  You need to move to Crystal Reports for Visual Studio (.NET).
