multithreading - Thread abort and ThreadExit not working visualstudio2008 c++ -

i'm using threads in c++ visualstudio2008, when form closes thread still stays active tried thread::abort when form closing, after calling thread still alive. set excption handler in thread , when abort exception arrive thread exit, thread not come in in exception handler. how can close thread? othread global object thread.

private: void threadmethod(/*object^ state*/) { try{ socket server; wsadata wsadata; sockaddr_in local; int wsaret=wsastartup(0x101,&wsadata); if(wsaret!=0) { return; } local.sin_family=af_inet; local.sin_addr.s_un.s_addr=inaddr_any; local.sin_port=htons((u_short)20248); server=socket(af_inet,sock_stream,0); if(server==invalid_socket) { return; } if(bind(server,(sockaddr*)&local,sizeof(local))!=0) { return; } if(listen(server,10)!=0) { return; } socket client; sockaddr_in from; int fromlen=sizeof(from); int buffer; char buff; //this->invoke(gcnew methodinvoker(this, &form1::updatebutton)); while(!stop) { client=accept(server,(struct sockaddr*)&from,&fromlen); //con la struct int numbyte=recv(client,(char*) &mystruct, (int) sizeof(mystruct), 0); this->invoke(gcnew methodinvoker(this, &form1::updatebutton)); messagebox::show(mystruct.num.tostring()); closesocket(client); } closesocket(server); wsacleanup(); } grab (threadabortexception^ e) { exitthread(0); } exitthread(0); } private: system::void form1_formclosing(system::object^ sender, system::windows::forms::formclosingeventargs^ e) { othread->abort(); if(othread->isalive) { messagebox::show("ok"); } } }; }

how this:

// create socket non-blocking int mode = 1; ioctlsocket(server, fionbio, &mode); struct timeval timeout; timeout.tv_sec = 0; timeout.tv_usec = 100000; // 0.1 sec fd_set server_set; while (!stop) { fd_zero(&server_set); fd_set(server, &server_set); if (select(server + 1, &server_set, 0, 0, &timeout) == socket_error) { // error handling } if (fd_isset(server, &server_set)) { // phone call take , other stuff } }

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
