I use VS 2008 and I write in C# .NET.

I've to:
1) open a report
(please for the next step consider I don't really know what there is inside),
I use :
ReportDocument rpt = new ReportDocument();
rpt.Load(strPath);
ok?

2) set an database.mdb as source of data,
I've find this way:
rpt.SetDatabaseLogon("", "", "localhost", "C:\\Sample.mdb");
not shure about the parameters. is it correct to write "localhost"?
2b) do I have to pass parameters?
I don't know anything about these.
I know there is the method SetParameterValue, but I have to make this step automatically... How can I do it?

3) export in PDF
I've find some code to set export options and the method Export(crExpOpt)


I've to do all the these things without user interaction and without the Viewer.
Can someone  help me?
Thank you so much.
