Sample Descriptions
Name Category Description
Arrays Intermediate This sample shows how to use TROArray for presentating DB tables in a master/detail relationship.
Async Introduction This sample shows how to call methods on a RemObjects SDK server asynchronously.
There may be times where you want to submit a request for information and defer receiving the result until a bit later. A very simple calculation (Sum) is performed, but this has a built in ten second delay so that it is possible to query the server before the calculation is completed.
Auto Server Introduction
Architecture This sample shows how a client can control its server when they are both running locally. This is useful if you want to provide a simple standard alone solution which is easily upgraded to multi-tier (or you might want to provide both options).
Broadcast Chat Intermediate This example shows how to use the TROBroadcastServer and TROBroadcastChannel channels to write an UDP broadcasting chat program.
Class Factories Architecture
Advanced This example shows how to use a Class Factory to generate three types of server:
Singleton: all clients access a single server object.
Single Call: server instances are created on demand and destroyed after processing the method call.
Pooled: multiple server instances are accessible by clients. This works exactly the same as Singleton, unless the first server instance is busy.
Note: to test this sample properly, you need to run at least two clients.
COM Advanced This sample shows how to call an existing RemObjects SDK server using COM.
DataSnap Architecture Standard example of the use of the TRODataSnapModule and TRODataSnapConnection components.
Dispatch Notifier Architecture
Advanced This example shows how to customize message dispatching. IRODispatchNotifier is a special interface that TROInvoker classes know and look for.
If your server side object implements it, the IRODispatchNotifier.GetDispatchInfo method will be called before the target method is invoked.
Dynamic Request
(not shipped with the trial version) Introduction This example shows how to use the TRODynamicRequest component to execute server methods.
Extended File Transfer Intermediate This example shows how to transfer files to and from a RemObjects SDK Server in chunks and how to monitor new files via server events. Note: needs at least two clients open. File(s) uploaded from one client are downloaded to the other(s).
First Sample Introduction This sample provides an introduction to using the Delphi edition of the RemObjects SDK product. The example shows how to define/implement methods on the server and how to access them from the client. The data consists of name information and four simple methods are provided by the service: Nicknames, VerifyName, CheckName and FullNames.
FPC Server Architecture
HTTP Chat Channels This shows how to use polled events to create an HTTP based chat program.
The clients poll every few seconds for new messages and the server distributes the messages to the appropriate client(s).
MegaDemo Channels This comprehensive example illustrates many of the features of the RemObjects SDK by providing benchmark facilities for the various protocols and channels supported.
Multi Channel Introduction
Channels
Architecture This example provides an introduction to using the Delphi edition of the RemObjects SDK product. It shows how to use different channels to connect to the server application.
Named Pipes
(not shipped with the trial version) Channels
Intermediate This example shows the use of a named pipe connection. It creates a named pipe server as a Windows service.
Proxy Server Architecture
Advanced This example shows how to create a proxy server to redirect the calls to another server without having to recreate the RODL file, thus allowing the use of the same types of the original server.
This provides total control. As every call will pass from the proxy class before going to the real server, you can even stop methods from being dispatched any further.
RODL
(not shipped with the trial version) Introduction
