Need help

rbuser

I need to know how can I access the values of report custom parameters.

in the client side I have this code :

rsClientReport.VolumeName := 'GesComPlus' ;
rsClientReport.ReportName := 'Contactos\Contactos' ;
if rsClientReport.GetReportParameters then begin
rsClientReport.ReportParameters.Clear ;
rsClientReport.ReportParameters.Items['ppDataBase'].Value :=
t.DataBase ;
rsClientReport.ReportParameters.Items['ppContactosTiposID'].Value := 1 ;
rsClientReport.ValidateReportParameters ;
rsClientReport.Print ;
end ;



at the server how can I access this values ?????


Thanks

See the following article and check out the RBServer\Demos\ that are related
to csutom parameters. Each example contains a ReadMe.doc.

I. SessionParameters
--------------------

1. Each time a client communicates with the server, the client must send the
session id.

2. Each time the server receives a client request, it authenticates the
request. These are the possible cases:

a. No session id specified or invalid session id specified
Validate the session parameters passed from the client. If valid, then start
a new session and generate a new session id. The session id will passed
back to the client.

b. Existing session, no session parameters specified or same session
parameters specified.
Use the session parameters for the existing session.

c. Existing session, new session parameters specified.
Validate the new session parameters.

3. The SessionParameters are always passed to the custom parameters related
events.

a. For the TrsServer events such as OnValidateSessionParameters, the session
parameters are passed in the "aParameters" parameter.

b. For the TrsReportVolume events, there is an "aEventParams" parameter that
contains a SessionParameters property (i.e. aEventParams.SessionParameters).
Note that the aEventParams object contains a different set of properties
depending upon the report volume event. The specific properties are
documented in the online help


II. ReportParameters
--------------------

ReportParameters are only relevant to a request for a specific report. The
relevant ReportVolumeEvents that are provided are: OnGetReportParameters,
OnValidateReportParameters, and BeforePublishReport. Each of these events
passes an "aEventParams" object to the event-handler that contains the
SessionParameters, ReportParameters, and other information. Again, note that
the aEventParams object contains a different set of properties depending
upon the report volume event. The specific properties are documented in the
online help.

The ReportParameters passed from the client are automatically assigned to
the TppReport.Parameters property. In the server custom parameters demo, the
ReportTemplateVolume.BeforePublishReport event is implemented to add the
session parameters to the TppReport.Parameters.
