ok but when send and recv from windows to this device work well
but when change windows ->unix the system sometimes hange sometimes work well

thanks for replay but i want to complete sequence no hang at half
the code run sometimes right some times complete
so i want guarantee to send guarantee to receive

but i see unlike when i send data in range unsigned not signed and i receive wrong data i do like your solution but doesn't work well

thanks i will try for that
thanks alot :)

thanks for response
but some time connected server hang recv still block for ever

thanks for that this problem occur where server restart and reset its configuration where problem are you think

i cant debug due to on unix i write on text and run code with display message it connect then send first command and send second then replay
when send third command may be connection loss or time out but when telnet normally it return data well
this problem suck me
thanks for response

is there configuration on aix solve this problem of timewait

ok thanks for this tips
but why it working for some server but other not
but when i use telnet command i work well i work on unix platform
when i reboot system this problem occur before thant there is nooo problem

thanks alot
but i change code as you say
and the time out occur for some server although when use telnet command line it return data

it work correctly for almost server expect some one
so i ask is the read function get all data in all cases or not

ok but max wait is 35
and it work correctly for almost server expect some one
so i ask is the read function get all data in all cases or not
----
memset i use it dure to under it i read all data for single if memset remove
may be add return response of previous command + current command

yup

O_NONBLOCK not recognize on AIX7.1 i use FIBNREAD

iam so sorry but i write quickly and capslock open :D

OK IF THIS CASE YOU SAY OCCUR HOW TO OVERCOME ALSO
DUE TO THIS SERVER MAY BE WRITE TRUE TO IT BUT NOT RESPONSE SO I WANT TO SOLVE WAITING

i can't know problem with this piece of code but
try to debug on selection changing event on drop down list
and check when call select function the event occur one or more one time

your solution is logic and i will do it but there are service that connect to this all time with no limit need all to handle

i work on AIX ibm 7.1 server with with 16 core every core 3.7 GH and ram 16 G ram
so i think this is no probelm and it it background service so difficult to debug
i use instead show message

are you solve it
i face it now

not work

why you check on previous on datarowbound event and this event occur every row may be case terminate your program in first bound row

i know it wrong it just dummy code i want to cast

it compile fine but i need to send unsigned char
i will update question
sorry for this

not tcp but the data in accept in write function

I MEAN THAT multi-thread application every new thread have access to database
and this code

m_Manager->c_section.Lock();
int res=m_Manager->m_DB.BookFreeTestHead("AXE",&h);
m_Manager->c_section.Unlock();
printf(" res is %i ",res);

in thread and another threads also BookFreeTestHead but i did't want two thread have the same free test head

Ok thanks for your time ,respect and your replay
i will try agine if i fail i will post question with this code and add other relevant information.
:) :)

ok this code snippet inside parse function due to you say i'am not ensure
parse function do :)

i accept it to write a comment on it only

thanks for advice but a problem but the same problem is still not solved
the function parse take a pointer of vector list and i change of it
then i use it after function return 0 value to ret variable so function it work correctly

no i use on windows visual stdio 2012 and use on linx gcc 4.9
but on unix xlc also the same problem
it also run on oracle linux only

i sorry for new question but i solved it it linux and run then i see your answer i try it in windows problem doesn't solve

i sorry for this i mean the same code dosen't run on windows but it run well on linux

it work on linux but windows no
vector<cparsertoken*> &cop =mycom->param;
// mycom->get_first();
iter = cop.begin();
int i = 0;
for(;iter!=cop.end();iter++)
{


k = ParseTokens(*iter,NULL,token, temp, polist,true);

if(k<0)
{

return k;
}
}

it already like that i will change it now in post sorry

it return vector iterator incompatiable and program stop at comment //program stop

in debug viewer it appear that it call deconstructor of TCPserver socket and
shut down it it return this error socket is closed so what about when i bind socket
agine in deconstructor to listen agine or this way not optimized

iam sorry for that but it thousand of line of code and also it work well for 30 min then stop and start
i post this question expecting may be a common guideline for this probelm

this windows service is listening on port 6000 to handle any request on it by tcp conncetions
there is main thread tcp for listening and all chaild tread that handle connection and process request but after 30 min the service close listening socket up normal

thank you , i have been able to link the library

i know but when i commentated while true that contain read and write for each connected client the accepting more client work perfectly but every client open session read first and server return response one time i wont every client write and read from server all time

Thanks for time but it also did't solve the problem is if first thread that accept connection
accept client and begin to read and write the thread that accept wait to end read of the read thread but i need accept run all tim eand read write to other client also run and handle all time

ok but re->start already do this and Handleresponse inherit from thread that call run in every drived class

OK really THANKS FOR YOUR TIME :)

thanks problem solved
the problem like you say in type casting
but after accept it closed thread and listing why

I know i write it like this but this is not problem when i change to dynamic_cast
the server dosen't listen when i telnet on it
((ITCPServer *)&run)->Bind();
// (dynamic_cast<itcpserver*>(run))->Bind();
if i reverse comment the server dosen't fire listen thread
i really heat that

(dynamic_cast<itcpserver*>(run))->Bind(); doesn't run program couldn't be run

i try to print Socket variable after Socket = socket(PF_INET,SOCK_STREAM,0);
it take a specific value
but when i use it before accept
accept(Socket,(struct sockaddr*)&client,(unsigned int*)sizeof(client)))
Socket always take default value here of constructor
why this occur i call first Bind() function in main function then call start listen

this is reserved function
i talk about Socket dosent change in cooment

No for what :)

yes exactly i mean it :)
thanks

i know but i convert string to byte must be in specific format so when i get byte in format windos-1256 cannot convert into iso-8859-1 data Lose

if i use string to decrypt it must be in format iso-8859-1 else it generate error in decoding but when i use this decryption on system support only windows-1256 encoding the encrypting
string save with data lose when i get it to decript generate error

i use cipher rsa encryption
i get byte by memeber function getbytes in string

this in C# i want in java

i sorry i know, may be i use wrong words but this errors not occur constantly i want to prevent it permanently for that i optimize code
if you have windows multi threading code in c++ 6 and mutex aemaphore in one project
you will help me ////////////
this code

yes as you say my brother :) but first the stack overflow occur in say as example on the
line 20 when i use memory pointer in these variable in may be case at line 50
or not due to this is peace of threading application

this case cause stack overflow //if i do like this

I MEAN GAME ENGINE HAVE EXCELLENT TUTORIAL AND I CAN DO FANTASTIC GAME WITH NO RESTRICTION IN EFFECTS AND PERFORMANCE

thanks :)

THANKS I WILL TRY IT REALLY I SEE CODE MORE TIME BUT I DIDN'T SEE IT I HOPE THIS TO BE THE PROBLEM THANKS VERY WELL :)

thanks for hint i improve question :)

it is a
windows service the debuging data just some long address in memory <br>
 <br>
but can i optimize this function or divide it into two function

i cant due to it thread section from big multi threading question
but what should i do

and this peace of code is only threading function

when i comment the function
m_Manager->m_DB.zte_get(terminalid,(int &)*rac,(int &)*shelf,(int &)*slot);
it run well bur if i return it the threading didn't complete the the function

thanks for replay but this peace of code it run well alone but when i embedded this code in
threading system it case stack over flow or access violation when i call more time i think
due to the large string

may be right but when i debug it on this string it work well but when i commit in app
may be run and may be not it case stack overflow when i call more times in threads

OK for example when i call parsing function for first time and second it work correctly but when i call third times it case stack over flow but when i work on high ram it work perfectly

thanks for replay but i want to send and receive data throw this port or to be more accurate
i want to sniffing data throw this port

thanks very much for your interesting , thanks alot

yes it is interactive services :D

yes i do this and also i pass the full exe path in command line and parameter but don't work it should be work as console application not as windows service

i want to run exe file from service due to if i restart machine the service automatic run exe file with no need from me to run it

if i create process like your code is it run or not due to i try this code and no action

it doesn't run with me , it run only when i run as console application not as windows service
