[twsocket] Exception handling in a Form
Hi May be I'm missing something, but... How can I catch an exception raised by an asynchronous function like TnCnx.Connect in a form. In a TApplication there is a Method for this (HandleException). Is there something similar for a TForm?

Re: [twsocket] Freeze when using smtp after recreating itsparentform
Hi Arno and others! Some of the heavy work load I experienced a while ago has decreased a bit so I thought that I should take the opportunity to thank You ALL that tried to help me. At the end the solution for me was to use another smtp component. Sorry about that. (As a request by Francois Piette I'm not going to mention it by name in this news group.) Even if it is like You say Arno, that the problem is not originating from ICS it is still toghether with the SmtpCli component the problem appears. This makes it impossible to use the SmtpCli component knowing that users might not be able to use our application under certain _normal_ circumstances (like in our test case with a new Dell laptop). We can not tell our users that they have to uninstall other softwares just to be able to send emails from our application. Even if it is not a bug in ICS code or design the fact remains: Other smtp components out there works just fine under the same circumstances. So that was why I was forced to take that path. But once again: Thank You all for the help! You are doing a wonderful job! Best Regards Henrik Arno Garrels wrote: The problem is *not a bug in ICS*. Instead another process injects and executes its own, buggy code in the process space of the ICS-application. Detoured.dll is used for hooking API calls. The hooking application is the culprit! That must not be a virus or trojan but may be any other application/service or security suite as well. -- 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
Re: [twsocket] Freeze when using smtp after recreating itsparentform
Strange logic Henrik, Even Microsoft's Works doesn't/didn't work with this buggy, API hooking Embassy Trust Suite pre-installed on newer DELL systems. Possibly they already fixed it in some service pack? If not, someone/we should report the bug to either DELL or Wave Systems. I was hoping that you helped identifying the Embassy Trust Suite clearly as the culprid. --- Arno Garrels [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html Henrik wrote: Hi Arno and others!

Re: [twsocket] Exception handling in a Form
Hello Veit, Normally the components handles their own exception by design (as it should be). Be sure you have no exceptions in events. If there is a chance that your code can raise an exception then you should have that event into an try excpet block and handle it. --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html http://www.mestdagh.biz Thursday, January 25, 2007, 17:04, Veit Zimmermann wrote: Hi May be I'm missing something, but...

Re: [twsocket] Exception handling in a Form
Hello Arno, Perfect chaos, sorry. Please ignore this mail. That's because we are programmers :) However there is one thing. Hitting 'reply to all' does address the mail also to the original poster. I dont like it as it start often private mailings. And 'reply to all' is a common used button in buziness. Francois is this something you can disable ? --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html http://www.mestdagh.biz -- 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
Re: [twsocket] Freeze when using smtp after recreating itsparentform
I thought it was figured out that dynamically unloading and reloading the dll was the problem, which other components probably don't do, and I think you were given a workaround that worked...to load it manually so that the loaded count always stays above 0 and it remains loaded.

Re: [twsocket] Exception handling in a Form
Hello Wilfried Thanks for your reply. The answer is a surprise for me: Of course I know try except/finally, but why does it work when I wrap it around TnCnx.Connect? I thought this is an asynchronous method? But it works. I would have expected that the try/except block is left right after calling connect and not only until the connection is established or an exception occurs. Could you please explain this?
