this question has answer here: socket tcp c# how clear input buffer? 2 answers i using below code receiving tcp packets tool. while(socket.connected) { var buffer = new byte[4096]; int receivelength = socket.receive(buffer); if (receivelength != 0) { byte[] response= new byte[4096]; processpacketdata(buffer, out response); socket.send(resposne); } //sleep(100); } when using code, problem facing is,for socket.receive() function buffer doesn't getting flushed. every time, when calling socket.receive(buffer), new data packets getting appended old packets contained in buffer. want avoid situation. there solution this? receive not receive packets. receives amount of bytes greater 0 bytes. use return value receivelength find out how received , process amount.

in order improve loading speed of webpage want set expiration date images. not sure though how this. i loading image through css, through cloudfront s3 bucket in aws. specify expiration date? this example of how load pics: .bg-header { background: url("https://dt25rte355.cloudfront.net/assets/12456.jpg"); background-size: cover; height:480px; in directory containing files, create new file called .htaccess , add following inside: <filesmatch "\.(gif|jpg|jpeg|png)$"> header set cache-control "max-age=172800" </filesmatch> you can add additional file types regular expression, , apache add specified header every image request. note method require files hosted on server.

i'm using c# , making lists sqlite query responses. list1 contains field name of field in list2 list1[i].field = fieldname i want use fieldname stored in list1[i].field access item in list2 like: list2[ii].+list1[i].field+ i have no idea if possible in way in c# i'm relatively new , going off knowledge of php work. for type of data structure, use dictionary (key/value pairs) dynamically select properties of object. specific example, accomplished reflection, not commonly used since other structures make easier. list2[ii].gettype().getproperty(list1[i].field).getvalue(list2[ii], null); reflection isn't fastest type of solution typically, , it's not great come in behind , maintain code lot of reflection if can avoided. alternatively, use linq transfer list2 list of object types list of dictionary objects list2[ii][list1[i].field] accomplish same thing. var listdictionaries = list2 .select(l => new dictionary<string, object>()

i looking general debugging "tricks" finding source problem of kind of error message: build/nat.cpp.o:(.bss+0x0): multiple definition of `input::hellocounter' build/sam.cpp.o:(.bss+0x0): first defined here collect2: error: ld returned 1 exit status here, input::hellocounter global variable defined in header file, header file well-guarded ifndef... . pasting source here should pointless there many. wondering whether have general techniques debugging in such situation, e.g., inserting special code expose issue? information, using ubuntu 14.04, clang/g++ compiler. this implementation-specific issue. did not specify compiler or operating system using, no particular platform can offered. however, example, in similar situation on linux use nm(1) tool binutils search object code files ones define symbol, locating object code files define it, , determine ones should not have defined. once it's known object code file's definition should not there, co

okay, first of all, i'm new directx11 , first project using it. i'm relatively new computer graphics in general might have concepts wrong although, particular case, not think so. code based on rastertek tutorials . in trying implement shader shader, need render scene 2d texture , perform gaussian blur on resulting image. part seems working fine when using visual studio graphics debugger output seems expect. however, after having having done post processing, render quad backbuffer using simple shader uses final output of blur resource. gives me black screen. when debug pixel shader vs graphics debugger, seem sample(texture, uv) method returns (0,0,0,1) when trying sample texture. the pixel shader works fine if use different texture, normal map or whatever, resource, not when using of rendertargets previous passes. behaviour particularly weird because actual blur shader works fine when using of rendertargets resource. i know cannot use rendertarget both input , outpu
