I am migrating the reporting functionality of my company's web
application from Crystal Reports 9.x to SQL Reporting Services 2000,
and I am using the Reporting Services web service to render the reports
to the browser (typically as PDFs). The typical process for retrieving
a report is as follows:
1. A screen in the parent browser window collects the report criteria.
2. A button click posts back the parent window to process the criteria
and a new browser window is opened via Javascript, with the parameters
for the report passed along in the query string.
3. The ASPX page in the new browser window (child window) processes the
query string parameters, and requests the report from the Report
Server.
4. The binary array returned from the web service is written to the
response stream (with proper header information set for the file type)
and the report is opened in the child browser window.
The above process works without fail. The issue is, sometimes (and
only sometimes), when posting back in the parent browser window after
the report is rendered in the child window, the page trace is rendered
along with the HTML. Trace is disabled at both the page and
application level (in the web.config), but the trace still appears.
I'm assuming this has something to do with rendering the PDF, but I
think I'm dotting all the Is and crossing all the Ts as far as
rendering the report to the Response stream:
Code is below (VB.Net):
results = reportProxy.Ren der(ReportName, format, Nothing,
Nothing, Parameters, Nothing, Nothing, Encoding, MimeType, Nothing,
Nothing, Nothing)
Response.Append Header("content-length",
results.Length. ToString())
Response.Append Header("content-disposition",
"inline:filenam e=" & ReportName & "_report." & extension)
Response.Conten tType = contentType
Response.Clear( )
Response.Binary Write(results)
Response.Flush( )
Response.Clear( )
Response.End()
Am I missing something that might cause the trace to rendered on a
different page?
TIA,

I have a datagrid in my web control class that I am trying to get the current
rows displayed for. I have enabled paging on the datagrid so if the user is
currently on page 3 of 8, and if I have allowed for the table to show only 5
rows at a time, for example, I want to get the 5 rows that are displayed on
page 3 of 8. How do I do this???? Thanks!

Hello
I am currently in the process of creating a web page to display and edit reporting data. It consists of a few label
with instructions, a Drop-Down-List and Button (Load) to select a report to display, when the user selects a report and clicks the load button it will perform a postback and populate a datagrid on that page. The datagrid also exposes an edit button that they can click, which fires the EditCommand function and allows them...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
