I am getting a little further, but still having issues...

If you need more information, I'd be glad to give it, but I am
developing an ASPX page so that the user can select multiple values for
a specific field, then pass them on (using Crystal Reports 10 on a
separate ASP page). Here is the code behind the button that will
launch the report (is in a file called StateSelect.aspx.vb:

Protected Sub Button2_Click(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Button2.Click
Server.Transfer("/NewCrystalReports/genericreport.asp", True)
End Sub


When I launch the ASP page and hit the submit button, I get the
following error in the IE window:

Brent,

I'm pretty certain that you can't server.transfer from a new ASP.NET
application back to an old ASP application. Server.Transfer will try to make
your ASP.NET application load the .asp page into it's runtime. That of
course can't happen since the code is foreign to it.

Brent,

Yes, Sreejith is correct you need to use a Response.Redirect. And then
include the values you need to pass to the ASP page in the querystring.

I don't suppose there's a way to pass the request parameters through
code instead of appending it to the URL, is there?

I ask because what I am passing is a filter selection for a Crystal 10
report that contains the States the report should be viewed for and the
report name itself (to lessen the number of ASP files I have to maintain
in the virtual directory), and that URL may be quite long and contain
some illegal characters.

 

[S. Justin Gengo]

Brent,

The only other thing I can think of is a bit lengthy, but you could put a
literal control onto a page and then use the HttpWebRequest object to post
to the page with the included parameters and then render the results to the
literal.

That would look something like this:

***Also a word of warning. It took me a while to get this working (sorry it
took so long to post back) because I kept getting 405 Method not allowed
errors from the site I was testing this code against. It turned out that the
server was refusing the posted data because I was using fake parameters. You
have to post with each and every paramter named exactly as the page is
expecting and go directly to the page or you'll get that error.

Another approach would be to create a table to hold the transaction data for
the report..

steps would be like this...

create a key value from asp.net page
save params for the report in the transaction table with the key , from
asp.net page
redirect to the asp page & pass the key using query string
read the parameters from asp page
delete the record in the transaction table for the key, from asp page..

What Justin suggested may be a better solution than this. if the crystal
report is being opened in the same window as asp page , would assigning the
response to literal work ? the Request.ContentType will need to be changed i
suppose. not sure..

Sreejith,

Good point. I was assuming that it's a web report. If it isn't then a
response.type coud be set to deliver the stream as a file.
