Hi again,

October 26. 2019 at 15:30 (3:30PM) CEST (UTC+2) I presented kbmMW core features.

The presentation focused on the central pieces of kbmMW like the transport, transport stream, custom service and simple client, in addition to showing a little bit about the traditional query service and client features.

If you have a great idea for a topic, and perhaps even would like to present it yourself, then just contact me on email at kbm@components4developers.com. I welcome just about anything of interest for Delphi, as long as its legal and can be viewed by minors. Even presentations about competing products are valid topics!

  1. Kim,

    Some questions:
    1. When I have a service derived from TkbmMWCustomQueryService how can I make it multi-threaded? I.e. when there are multiple users and threads requesting TkbmMWClientQueries how can I make them run in different threads so that one long query of one user would not make everybody wait? Where can I read more on that subject?
    2. Is it possible to have TkbmMWClientQuery on a client side but on a server side to have a procedure that would construct the dataset ‘manually’ instead of using pre-made query components? Is there any documentation or sample code?
    Thanks in advance,
    Alex Liberov

  2. Hi Alex, I will try to answer you with the things I have already learned.
    1) Any KbmmwXXService is Multithreaded, the only thing you need to set the service flags that is if there will be a Pool for a limited number of instances of a service:
    // Return the maximum number of instances that is allowed to run.
    {$IFNDEF CPP}class{$ENDIF} function TkbmMWCustomServiceXXXX.GetMaxInstances:integer;
    Result:=-1; //unlimited

    or you must create an instance per thread/session (stateful). In the kbmmw service wizard, select ‘stateful’ service.
    {$IFNDEF CPP}class{$ENDIF} function TkbmMWCustomQueryServiceXXXX.GetFlags:TkbmMWServiceFlags;
    check demo: Demo\Basic\Stateful
    2) Dont understand exactly your question, do you mean to use a clientside query like ‘select * from XXxxxx’ , withotu having to have a corresponding Server side qury object for that select? the queyr servcie is for that, ti create a new TkbmMWXXXquery (FireDAC, ODAC, ADO, Etc) on the fly when a sql query is submitted via kbmMWClientQuery.

    check demo:
    Demo\Basic\Client (Coomont client demo)
    Demo\Basic\SQLiteServer (serve side demo using SQLite database)
