Hello ICS team,
I´m currently using your implementation of shared handles in all my
applications (I have actually removed all AllocateHwnd and changed to use
your implementation in your to share handles between objects and save some
OS resources), and I think that I have found a flaw in the
Well
I have seen that you UnregisterMessage routine already removes messages from
the queue:
if FHandle 0 then
while PeekMessage(LMsg, FHandle, Msg, Msg, PM_REMOVE) do {loop} ;
Strange.. must be something else, I will keep digging!

Hello!
I would like to know if ICS is already stable for 64bits development.
I`m porting my system to 64bits and I updated to ICS8, but I´m having many
issues (ICS is in the core of my system) that looks like memory overflow or
overwrite, so, I´m trying to find out the problems and I want to

normal router/firewall Port Forwarding, as per many good sites found
with Google. So much safer than letting UPnP work.

PS: UPnP is not the same as Plug and Play hardware detection, that is a
totally different animal.

I thought about that too
But I found the problem. The LocalAddr (or addr? don´t remember now) must be
changed to local IP address, not 0.0.0.0, or else I don´t receive the
responses
Thanks!

Hi
I´m researching on UPnP communication and I found that it relies on multicast
messages sent to address 239.255.255.250 on port 1900
I tried to receive messages from this multicast address using ICS but it does
not work. Using other multicast addresses it works just fine, but I simply
can´t
Hi Anton,
I call it directly, in order not to allocate handlers, if you create a class
with a handle and post a message to it, it will be the same as using TTimer
directly, because you will use as many resources as TTimer would use (1
handle per instance), unless you create a class that is
Hello
I would suggest the changing of constant WH_MAX_MSG in
OverbyteIcsWndControl.pas to a global variable to which we can change on our
software, without changing ICS code.
Doing this will allow us to control the amount of shared resources per handle,
giving the ability to create more
HI Arno
True, I think that will help, I will add this line to my ICS code to check
if it works, but I believe that it will work
I also think that this is something that must be on ICS code, on
UnregisterMessage as you proposed, not custom code.
I will test and come back to you soon

Msg := 0;
while PeekMessage(LMsg, FHandle, Msg, Msg, PM_REMOVE) do {loop}; // ==
added
if FMsgCnt = 0 then
DeallocateHWnd;
end;
Just a little correction
while PeekMessage(LMsg, FHandle, Msg, Msg, PM_REMOVE) do {loop}; // ==
added
Msg := 0;
Or else you will pass 0 to
That won't work since TIcsWndHandler declares a static array with
length WH_MAX_MSG.
Instead I suggest that TIcsWndHandlerPool gets a public, thread-safe
method which checks whether the value can be changed and would raise
an exception if not. This method would succeed only if the pool
was empty
Hi
I´m studying TICSWndControl so I can use it as base class for my app.
I´m curious about something, you have the constant WH_MAX_MSG = 100, which
means that each Handler created can handle up to 100 different messages, from
different objects right?
Is there a reason to be 100? If I increase
Hello all
While I was trying to use TICSWndControl as base class to share handles for

Windows limit the number of windows handles to 10.000. That's why ICS V7
is
designed to use only one handler for a lot of TWSocket so that you can
create a lot of sockets. Which OS are you using which allows creating
1.000.000 handles ?
After more testing, and a clear mind of a new
I'm still stuck with Delphi 7 at the office, so I don't know if this has
changed during the years. However, looking at the source code of
TIcsWndControl.AllocateHWnd(), it appears that it's still locking the
resource in order to create new handles. My guess is, no.
I think that they lock in

Reusing the design I've done is very easy. Just derive your class from
TIcsWndControl and override the methods
AllocateMsgHandlers, FreeMsgHandlers and MsgHandlersCount to get your own
messages. See how it is done in many ICS components. very easy.
It is really easy to use and it is
TIcsThreadTimer is a good choice for 10,000+ of lazy timers,
when accuracy isn't very important.
TIcsTimer is a 'normal' timer that requires a TIcsWndControl instance
to work. There are demos of both in the MiscDemos directory.
What I did was something similar, but not using messages

That is really nice, did you get that by just activating the desktop

One limitation with such kind of implementation (might not be relevant)
is that the application blocks until entire list of events is processed.
Like iterating over a list of n server clients blocks all clients.
Yes, that is true, but I try not to have long processing in timers, just
routines
Dear ICS Team,
I found a problem in our software that is limiting the total ammount of TCP
sockets that I can create.
The problem that I found is that I can´t create many many instances of
TWSocket, because of its internal message handler (I did many tests), here are
my findinds:
We use
It will be interesting to hear an answer to this...
Thank you,
Why? Is that a silly question? :(
I don´t know how ICS works internally, I´m just wondering what is happening

I´m having a problem with a customer, and I sucessfully reproduced the same

I have checked the ICS code, and I found this:

Sorry I misunderstood. I thought you used method DnsLookup.
So in this case it is simple to fix, call method DnsLookup and connect
with a dotted IP address from the OnDnsLookupDone event handler.
Hi Arno
Thanks for the clarification
So, if I use the method DnsLookup all the requests will be
Yes, it is safe, however I would consider to use WSocket_gethostbyname
as well (more work).
What is the differenc? I See that wsocket_gethostbyname returns more
information, but is there a reason to use it instead of the other method?
Thanks

Hi,
I had a very strange problem with your library v7 and Delphi 2010.
My software relies too much on RTTI for Record data, and (After loosing a whole

I should have searched it before.
I can also split into more servers if it is the case, to make a load

to D2009 yet. Will ICS-7 work on D2007?
