Question : Crystal Reports Shell in C#

I am looking for ways to make a shell for Crystal Reports using C# winforms.

Basically, to create a small shell that can load up crystal reports from file.

Most of the search for the said control online seems somewhat 'weak'.
I am using VS2008 and the control microsoft makes available is the

MicrosoftReportViewer

What I am looking to accomplish here is:

1) Load the reports from a directory (flexible)
2) The shell must be agnostic, ie, no change in code no matter what report it's being fed.
3) These reports are expected to have parameters of their own (such as "from" "to", company etc)

Answer : Crystal Reports Shell in C#

the Report Viewer is not compatible with Crystal Reports. it has its own viewer. check http://www.emoreau.com/Entries/Articles/2006/09/Feeding-Crystal-Reports-from-your-application.aspx
