Request user input through client-server reporting

rbuser

Hi,

I extended RAP with a function that shows a custom made input form to
extract some dates from the user.
This all works fine when the report is generated by the application that is
running it, but the report hangs when I use the function in a client-server
configuration.
Ths server side is build into a NT service application and the client side
is a stand alone app that connects to the server.

Is there a way to show forms and request user input through the
client-server configuration?

Greetings,
Ranjii.

I assume that are using RB Server Edition and creating a ClientReport app
that connects to an RB Server. In a Server environment all of the RAP code
executes on the server, thus you cannot write RAP code that displays any
dialogs. You need to implement code on the ClientReport side.

Check out RBServer\Demos\Clients\Custom Parameters and
RBServer\Demos\Servers\Custom Parameters. The examples work together. Each
example includes a ReadMe.doc and commented code.

Thank you, the whole parameter thing is working, sending to the server and
accessing the parameters in the report works fine now.
There is only one small problem, I can not seem to cancel the report;
I tried rsClientReport1.Canel when the user cancels the dialog on the
client side,
I tried checking if parameters exist in the report it self and if the
don't cancel the report,
I tried checking for parameters on the server side, but the thing just
won't cancel.
I'm probably missing something somewhere, but I'm getting pretty lost.

So the question would be; how do i cancel a report?

Greetings,

I researched this and currently there is no way to cancel a report that is
invoked from the report explorer. The ClientReport demo is using the
BeforePrint event to display the form. However, Report.BeforePrint occurs
too late to Cancel. For the next release we will add an
OnInitializeParameters event that contains a Cancel parameter that is passed
to the event-handler.

One alternative for implementing a solution with the current release would
be to create a custom ClientReportExplorer form that can show the parameter
dialog prior to calling print. You can register your custom
ClientReportExplorer as the replacement for the current
ClientReportExplorer. If you would like to pursue this, please send an email
to support@digital-metaphors.com and we can send you the source code to the
ClientReportExplorer.
