Ok, that sounds good. Now, in order for you to be able to see the reports in a web app, you will have to download SAP Crystal Reports, Developer Version for Visual Studio .NET (2010 / 2012 / 2013).
You will then have to add a bit of code to view the reports. The simplest code would be:
CrystalReportViewer1.ReportSource = <path to the report>
Now the above is pretty trivial, but lacks any power. E.g.; the report engine will prompt for DB logon and any parameters, which you may not want. Also, you will not be able to change the database logon (server, DB, table, etc.). For that you will have to expand the code. Once you have a working app, you will need to deploy the CR runtime to the server.
Perhaps the best place to start with all of this is here:
Crystal Reports for Visual Studio 2005 Walkthroughs
(Don't let the title throw you - the doc applies to all versions of CR and .NET)
There are a number of samples here:
Crystal Reports for .NET SDK Samples - Business Intelligence (BusinessObjects) - SCN Wiki
And of course the Developer Help files:
SAP Crystal Reports .NET SDK Developer Guide
SAP Crystal Reports .NET API Guide
One last thing. There really are two SDKs - Crystal Reports and InProcRAS. Both come with SAP Crystal Reports, Developer Version for Visual Studio .NET, however RAS is much more powerful in that it allows report creation APIs, may be a bit more stable (according to some people), provides finer control over tasks such as printing and so on. The Developer Help files for EAS are here:
Report Application Server .NET SDK Developer Guide
Report Application Server .NET API Guide
Samples are here:
NET RAS SDK Samples - Business Intelligence (BusinessObjects) - SCN Wiki
And a pretty good doc:
How to Use The RAS SDK .NET With In-Process RAS Server
