RE:Delphi6 - cristalreport ?
Tal ves la dificultad de uso entre versiones no sea muy diferente, no lo aseguro pues no he usado crystal, sin embargo, aqui dicen algo muy importante:
http://www.businessobjects.com/products/reporting/crystalreports/vcl/default.asp
"Integrate Crystal Reports into your Delphi and C++Builder applications using the Crystal Reports Visual Component Library (VCL). For registered users, four versions of the VCL are available to address your requirements:
1. Crystal Reports XI VCL - supports Delphi 7 and C++Builder 6
2. Crystal Reports 10 VCL - supports Delphi 7 and C++Builder 6
3. Crystal Reports 9 VCL - supports Delphi 7 and C++Builder 6
Note: Due to the addition of unicode compliance, the Crystal Reports 9, 10, and XI VCL cannot be used with older releases of Delphi, C++Builder, and Crystal Reports."
Osea que para delphi 6, hay que usar la 8 o anterior
