Re: [twsocket] best way to reset HttpCli
Francois, See my post, it is not sufficient to use OnRequestDone. There might still be messages pending in case of abort/network error when SetReady is called twice!

OnDocEnd is when the document is complete (Time to commit in database for example) while OnRequestDone tells you the component has finished your request and is ready for the next one. -- [EMAIL PROTECTED] The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

Make a property for it in the derived class then. This method would be much
faster than object recreation!

Re: [twsocket] best way to reset HttpCli
I've decided to just free/re-create the httpcli at run-time, works the best.

Re: [twsocket] best way to reset HttpCli
I think so,
If you call Abort, OnRequestdone will be triggered.
You can set a flag when you call abort, and then you can take action in
OnRequestdone.
You problably have to free some streams anyway, which are usually freed in
OnRequestdone.

Re: [twsocket] best way to reset HttpCli
I reported this as BUG in 2007. Then nobody seemed to find a real solution
and I found a workaround:
I created a descendent in C++ and,
void __fastcall httpClient::SetReady()
{
if(alreadySetReady)
return;
alreadySetReady = true;
PostMessage(FHandle, FMsg_WM_HTTP_SET_READY, 0, 0);
}
//---
alreadysettrue is reset before each get/head/postasync. Then you should
enter your next call in ONRequestdone. It has complex reasons yet if you
really want to know, breakpoint the original setready.

[twsocket] best way to reset HttpCli
Hi, I am using a httpcli created on run-time. I first connect to a website, and after DocEnd I call another procedure that changes the event procedures and connects to a different website. On the 2nd call I get an Exception "HTTP component is busy", so I do this before trying the 2nd call try LoginSocket.Abort; except end; that, however, generates another exception. Checking the httpcli state before the abort, it is "Waiting Body" What is the best way to "reset" the component between both calls and leave it in a "Ready" state? The first call is GetAsync and the 2nd one is PostAsync. -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
