send http request

samme sekund er nok lidt svært - bare den tid det tager at spinne diske op, lave
BIOS check, begynde at starte Windows op er nok mere.

Men du kan sagtens bede Windows scheduler om at køre et program ved boot.

Du kan sende en HTTP request med et færdigt program som f.eks. wget.

Det er heller ikke svært at kode selv (og nu er spm. jo stillet i C/C++).

Jeg har postet C kode til det mange gange.

et af dem:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>

#include <windows.h>
#include <errno.h>

void get(char *hostname,int port,char *path, char *fnm)
{
  FILE *fp;
  int sd,status,len,first,tmp;
  char cmd[512],resp[51200],*body;
  struct sockaddr local,remote;
  struct hostent *hostinfo;
  /* create socket */
  sd=socket(AF_INET,SOCK_STREAM,0);
  if(sd<0) {
      printf("Error creating socket: %s\n",strerror(errno));
      goto fin;
  }
  /* bind socket */
  local.sa_family=AF_INET;
  memset(local.sa_data,0,sizeof(local.sa_data));
  status=bind(sd,&local,sizeof(local));
  if(status<0) {
      printf("Error binding socket: %s\n",strerror(errno));
      goto fin;
  }
  /* lookup host */
  hostinfo=gethostbyname(hostname);
  if(!hostinfo) {
      printf("Error looking up host: %s\n",hostname);
      goto fin;
  }
  /* connect to host */
  remote.sa_family=hostinfo->h_addrtype;
  memcpy(remote.sa_data+2,hostinfo->h_addr_list[0],hostinfo->h_length);
  *((short *)remote.sa_data)=port;
  tmp=remote.sa_data[0];
  remote.sa_data[0]=remote.sa_data[1];
  remote.sa_data[1]=tmp;
  status=connect(sd,&remote,sizeof(remote));
  if(status!=0) {
      printf("Error connecting to host: %s port: %d\n",hostname,port);
      goto fin;
  }
  /* send GET request */
  sprintf(cmd,"GET %s HTTP/1.1\r\nHost: %s\r\nConnection: close\r\n\r\n",path,hostname);
  status=send(sd,cmd,strlen(cmd),0);
  if(status<0) {
      printf("Error sending GET request\n");
      goto fin;
  }
  /* read response */
  fp = fopen(fnm,"wb");
  first = 1;
  while ((len=recv(sd,resp,sizeof(resp),0))>0) {
      if(first) {
          body = strstr(resp,"\r\n\r\n") + 4;
          first = 0;
      } else {
          body = resp;
      }
      fwrite(body,len-(body-resp),1,fp);
  }
  fclose(fp);
fin:
  closesocket(sd);
  return;
}

int main(int argc,char *argv[])
{
  WSADATA WSAData;
  WSAStartup(0x0101,&WSAData);
  get("www.eksperten.dk",80,"/img/elogo.png","elogo.png");
  WSACleanup();
  return 0;
}

fløjt hvis du skal bruge en Linux version

sorry ventetiden Arne.. der har været gang i den på mit job..alt for mange web templates skulle klargøres, og sådan du ved...

FFLLØØJJTT  :)

prøv:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>

#include <sys/socket.h>

OK ?
