Re: [twsocket] Freeze when using smtp after recreating itsparentform
I have not paid very much attention to this duscussion, but I want to say something about using ICS on many diffent computers and different platforms. My company have made software based on ICS that run on W95, W98, NT, W2000, WXP and Vista. The components used is HttpCli, SMTPCli, HtmlSMTPCli, POP3Cli, HttpServer, SocketServer and WSocket (including the SSL-versions of the components). I have no problems on any platforms. The only time I have had problems, have been other components that needs for example Mime32.dll or other dll's that come from installing programs that is not standard in the platform. Or maybe to old winsock. Some times I have had trouble when freeing a component from inside an eventhandler for the component, or freeing a form that contains a component that is still working, but that is bad programming, even if it made problems only on some of the platforms.

Re: [twsocket] Freeze when using smtp after recreating itsparentform
Hi Arno and thanks for Your effort!
I'm sorry to say that Your answer doesn't promote ICS at all. I don't
possess enough knowledge about winsock and smtp to be absolutely sure but I
am not willing to accept that it isn't possible to use ICS components on
"all" computers. (You can see the answers on Your questions in Your message
below.)
If I can't be sure it's going to work on the majority of my customers
computers I can not use ICS smtp components.
So, since I really like ICS I go at it once more; These are the known facts:
- Everything works on all tested computers if we let one smtp component
exist at _all_ time when the application is running. (It doesn't have to be
the one used to send the emails. See my work around code). As I said I have
almost no knowledge about smpt communication (that's why I use ICS) but
isn't this a tell tail about the error that obviously can appear in the
component under certain circumstances...?
- The recreate approach (create the component when needed and free when
ready) works on all computers using other smtp components, for instance with
Indy. (Indy has problems with Swedish characters in the subject so I must
switch to use some other smtp component. I already use ICS in another
application so I would very much like to use ICS in all of my application.)
- Arno: Even if we don't understand _why_ it works: Is there any harm using
the strange work around I attached earlier? (Just to bee on the safe side on
computers where the component error may show...)
Sorry to bother You all with these emails.
I really appreciate all the help I get!
Best Regards
Henrik

Henrik,
I still guess that it's caused by any crap process running on this box. Why
else does it not happen on other computers as well?
[Henrik]: It does happen on other computers. I assure You that the one I use
were I get the same freeze as my customer, has no real-time protection
software, internet security suites or malicious software, anything like
that.
I don't know the Norman software, but have you tried to uninstall it?
[Henrik]: This is not the problem as You can read in my earlier posts. (FYI:
It's a widespread Antivirus software from Norway.)
I would also check the auto-started processes as well and turn them off one
after the other. Then I would search for strange processes in the process
list that do not exist on the other, working boxes. That's at least worth a
try.
[Henrik]: Even though my opinion I wrote early in this mail, that I can't
check this on all my customers computers, I've checked this on my test
computer. Everything seems ok.

Thanks, I found the problem:

// Release the database lock.
UnlockServiceDatabase(sclLock);

It simply got the service hanging during system boot if service type
was auto. Just FYI.
BTW, the function is useful in adding the description but it should be
called after install or a few mins.

You can also specify a LoadGroup, that is the name of the load ordering group of which your service is a member. The startup program uses load ordering groups to load groups of services in a specified order with respect to the other groups. The list of load ordering groups is contained in the following registry value: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\ServiceGroupOrder Also check value of property ErrorSeverity (dwErrorControl). http://msdn.microsoft.com/library/en-us/dllproc/base/createservice.asp?frame=true http://support.microsoft.com/?scid=kb%3Ben-us%3B102987&x=9&y=13 Have you tried a service-depency on RPCSS? --- Arno Garrels [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html -- 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
