i writing qt tcp/ip client. want check connection state server before send data sever. far knowledge can following methods use bool ' connectionstate ', set variable when connected sever , reset variable on disconnected() signal. before sending data server (client->write()) check value of variable. use ' client->state() == qtcpsocket::connectedstate ' way check connection state. which practice. or other method this. thanks in advance. qtcpsocket derived qabstractsocket , provides state() function. returns 1 of following enums: - enum socketstate { unconnectedstate, hostlookupstate, connectingstate, connectedstate, ..., listeningstate } so, assuming m_psocket qtcpsocket , check if connected:- bool connected = (m_psocket->state() == qtcpsocket::connectedstate); you add boolean , keep track of state, if network error occurs need ensure in-sync actual connection state.

i expect that data begins @ example 0x100 (memory location) , before it's commands... not sure! help! okay, detail question: see memory long array 1 byte space. space filled hex numbers. variables can fill memory example 0x0000 - 0xffff. how know example 0x002f command (for example 'mov') or number data? the cpu doesn't know. it's conventions. when start computer or embedded device starts executing bootloaer flash storage. in turn, bootloader loads startup code persistent storage memory , starts executing (typically os kernel) @ address loaded it. in turn, kernel load additional modules , init code @ known memory locations , execute there. at point, memory virtualization enabled, , executable files loaded in memory , each associated process , address space. executable header , os conventions define code , data segments locations. but code segment may contain embedded data, , dynamically allocated memory may contain code, instance in just-in-...

i'm designing report can have 1 or n elements in datatable. if report has 1 element, won't have page break. if report has more 1 element, want after every element page break. got variable (true or false) asl in condition if there more elements. i'm using eclipse birt version 4.3.1 thanks in advance if have footer row or that, can add following oncreate script row: if(vars["trueorfalsevariable"] == true){ this.getstyle().pagebreakafter = "always"; } and, of course, else if want force no-page-break (but should work automagically if element small enough).

i have in c++ for ( rowidx = 1; rowidx < (nbrows - 1); rowidx++ ) in order using cuda ,how should handle it? because in cuda do: if (rowidx < arraysize) ... if set rowidx=1 before calling if (rowidx < arraysize) , doesn't work. ----update ---------------------------- a simple example illustration. __global__ void test_func(int *a_in,int *b_in,int *c_out) { size_t rowidx = blockidx.x * blockdim.x + threadidx.x; rowidx=1; if (rowidx <array_size) c_out[rowidx]=a_in[rowidx]*b_in[rowidx]; } //fill matrices (int i=0;i<array_size;i++){ a_in[i]=i; b_in[i]=i+1; c_out[i]=0; } if use rowidx=1 ,then taking first result correctly.the rest zeros. for simple replace of loop given functionality provided in example, kernel can looks way. __global__ void test_func(int *a_in,int *b_in,int *c_out) { size_t rowidx = blockidx.x * blockdim.x + threadidx.x; if (rowidx > 0 && ...

i creating tcp server in c# 5.0 , using await keyword when calling tcplistener.accepttcpclientasync , networkstream.readasync however when check cpu usage of server process explorer have following results: tcp sync version: 10% cpu usage tcp async version: 30% cpu usage half of usage kernel usage. moreover, measured how many time received data adding counter inside while of network stream, , async version loops 120,000 times while sync version loops 2,500,000 times. in term of message received/second async version 15% slower sync version when receiving messages 3 different clients. why async version use lot more cpu sync version? is because of async/await keyword ? is normal async tcp server slower sync counterpart? edit: here example of async tcp server code public class asynctcplistener : itcplistener { private readonly serverendpoint _serverendpoint; // custom class store ipaddress , port public bool isrunning { get; private set; } privat...
