(New to WebForms) Crystal Reports Question

[JPdev]

Hello,

I'm trying to set up a crystal report viewer in a web form using vb.net/asp.net. I'm finding that the following line

CrystalReportViewer1.ReportSource = "C:\\report_1.rpt"

followed by

CrystalReportViewer1.Refresh()

Is failing with...
Object reference not set to an instance of an object.
etc...

Does anyone have any tips on how to setup a simple Crystal Report viewer in a web form. I've done this before in Windows Forms and not had trouble?

JPdev: I haven't used Crystal Reports but have heard it is pretty good stuff; here's an idea you might try. Several times in the past the "path" has failed (for other reasons) because it wasn't set to the "ServerPath". Just as an aside try:

Server.MapPath("myReports\report_1.rpt;"))

Again, this may not help but it worth a shot. Post back; this should be simple enough to figure out.

Using CR in a web form is NOT as simple as using it in a Windows app. I have struggeled with it in the past. Luckily it is better in VS2005.
There have been a few threads in here that I have responded to regarding CR. Also, there are many examples if you Google and on BusinessObjects website.

JPdev,

jbenson001 is correct there are lots of threads related to this. I have spent alot of time working with CR and asp.net and it's not as straight forward as you may think.
