Re: [twsocket] Design problem: function result and getAsync
Hello Lutz, Just write as always but you have a typical code that need to be executed in a separate object. So let the object behave as a normal ojbect. Later it is also very easy to use the thing in other applications. And you can use the normal async methods. unit uJob type TJobResult = procedure(Sender: TObject; const TheResult: string) of object; TJob = class private FCli: THTTPCli; FOnResult: TJobResult; procedure TriggerResult(const TheResult: string); public procedure GetResult; property OnResult: TJobResult read FOnResult write FOnResult; end; --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html http://www.mestdagh.biz Thursday, November 3, 2005, 03:26, Lutz Schröer wrote: > Hi, > I've got a small design problem with the GetAsync method.

This is a perfect case where writing a component (or a class) is very helpful. In the component or class, you can encapsulate everything related to a process and then use it from any other unit. -- Contribute to the SSL Effort.

It does not have to do with different units but with asynchronous nature of method GetAsync. Most async methods are also available as blocking methods, for instance GetAsync/Get. --- Arno Garrels [TeamICS] -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
[twsocket] Design problem: function result and getAsync
Hi, I've got a small design problem with the GetAsync method. My basic understanding is that after I called the getAsync method I have to do the further processing in httpRequestDone. This is no problem until I want to put the code in a different unit. For example: unit1.pas: -- function xxx.getResult(): string; begin http.getAsync; end; procedure xxx.httpRequestDone(Sender: TObject; RqType: THttpRequest; ErrCode: Word); begin // do some result processing end; main.pas: -- [...] result := unit1.getResult(); [...] Obviously this can't work. How do I have to design my unit so that I create a nice and simple function call in my main program but the actual code resides in a different unit?
