Delphi Labs: DataSnap XE - Callbacks

I was always intrigued by a possibility of doing callbacks in client/server, distributed applications. RAD Studio XE demos include "CallbackChannels" demo that shows how to use callbacks with different DataSnap communication protocols (TCP/IP, HTTP) and architectures (DBX, REST).

Delphi Labs: DataSnap - Passing "Plain Old Delphi Objects" Parameters

One of the cool new features in introduced in Delphi XE is a possibility to use TObject-descendant as parameter types in DataSnap server methods. I was planning to cover different possible parameter types that you can use in DataSnap applications, but it would be a huge discussion. Jim Tierney from Embarcadero has already discussed different [...]

Delphi Labs: DataSnap XE Transport Filters

Delphi Labs keep going! I have just published the latest episode in the "DataSnap XE" serie on communication filters. In DataSnap architecture you can use different communication protocols, like TCP/IP, HTTP or HTTPS, and you can also use transport filters that make it possible to programmatically access the raw stream of bytes that are transmitted between [...]
