编写了一个客户－服务器通讯程序，为何无法单步调试、

给的信息也太少了吧。
至少说明是app不能调还是dll不能调，是线程里面出问题还是socket通讯的时候出问题啊
连提问都不会啊

楼上的，是厦门的泊舟吗？呵呵，记得我吗？nice to meet u

编写了sock程序中，建立了client.cpp,server.cpp文件，里面都有main()
运行过程应该是先运行server.exe,再运行client.exe，现在问题是，在vc中我要先启动 server.cpp，但我无法单步调试，说好像无debug信息。

程序很简单，是最基本的了。相当于helloworld.刚刚开始学。
我如果想单步调试，却不行。：（help
1.先建立客户端公共函数文件connect_client.c，作用是建立sock,准备连接服务器端

struct servent *pse;      /* server information  */
struct protoent *ppe;     /*protocol information */
struct sockaddr_in sin;   /*endpoint IP address  */
int s, type;              /* socket description  */ memset(&sin,0,sizeof(sin));

        }

         memcpy(&sin.sin_addr,phe->h_addr,phe->h_length);         /*  host IP address  */
else if( (sin.sin_addr.s_addr=inet_addr(host))==INADDR_NONE )

   WSACleanup();

        }

        /**** get protocol number  from protocol name  ****/

if(strcmp(transport,"udp")==0)
       type=SOCK_DGRAM;

        /**** creat a socket description ****/
s=socket(PF_INET,type,ppe->p_proto);

if(  connect(s,(struct sockaddr *)&sin,sizeof(sin))==SOCKET_ERROR  )
   {
   printf("connect socket  error \n");
   WSACleanup();
   exit(1);
        } return s;

}
----------------------------------
2.新建客户端win32控制台工程，文件为client.cpp,并包含上述的客户端公共函数文件.
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <winsock.h>
#include "connect_client.C"
#pragma comment(lib,"wsock32")#ifndef INADDR_NONE
#define INADDR_NONE 0xffffffff
#endif
SOCKET  TCPconnect(const char *,const char *);
void    TCPecho(char *,char *);#define LINELEN   128
#define WAVERS    MAKEWORD(2,0)

void main(int argc,char *argv[])
{
  char  *host = "localhost";
  char  *service = "3333";
  WSADATA  wsadata;

  switch(argc)
  {
   case  1 :
   host= "localhost";
   break;
   case  2 :
            host=argv[1];
            break;
   case  3:
            host=argv[1];
            service=argv[2];
            break;
   default:
   printf("argment error\n");
   exit(1);
  }  if(WSAStartup(WAVERS,&wsadata)!=0)
  {
        printf("initalize failed\n");
   WSACleanup();
exit(1);
  }
  /********************/

  TCPecho(host,service);

  /********************/
  WSACleanup();
  exit(0);
}void    TCPecho(char *host,char *service)
{
  char     buf[LINELEN+1];
  SOCKET   s;
  int      outchars;

  s = TCPconnect(host,service);

  while(fgets(buf,sizeof(buf),stdin))
  {
     buf[LINELEN]='\0';
     outchars=strlen(buf);
     send(s,buf,outchars,0); if(buf[0]=='\n')
        break;
  }

  closesocket(s);}

--------------------------------------------------------
3.建立服务器端公共函数文件passive_server.C，作用是建立sock,监听客户端连接。
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <winsock.h>u_short  portbase = 0 ;SOCKET sockserver(const char *service,const char *transport,int qlen); /*-------------------------------------------------------------------
* udppassive
*-------------------------------------------------------------------
*/
SOCKET
UDPserver(const char *service)
{
   return  sockserver(service,"udp",0);
}

/*-------------------------------------------------------------------
* tcppassive
*-------------------------------------------------------------------
*/
SOCKET
TCPserver(const char *service,int qlen)
{
   return   sockserver(service,"tcp",qlen);
}

/*-------------------------------------------------------------------
*
*-------------------------------------------------------------------
*/
SOCKET
sockserver(const char *service,const char *transport,int qlen)
{
struct  servent  *pse;    /* server information    */
   struct  protoent *ppe;    /* proto information     */
    struct sockaddr_in sin;   /* endpoint IP address   */
    int  s,type;              /* socket description    */

    memset(&sin,0,sizeof(sin));
   sin.sin_family=AF_INET;
    sin.sin_addr.s_addr = INADDR_ANY;

        /* get portnumber from  service name    */
   if(pse=getservbyname(service,transport) )
   sin.sin_port=htons(ntohs((u_short)pse->s_port));
else  if( (sin.sin_port=htons((u_short)atoi(service)))==0)
{
   printf("  get portnumber error \n");
   WSACleanup();
   exit(1);
        }

        /* get protocol number from protocol name */
   if((ppe=getprotobyname(transport))==0)
    {
   printf("  get protocol number error \n");
   WSACleanup();
   exit(1);
        }

        /* choose socket type    */
   if(strcmp(transport,"udp")==0)
      type=SOCK_DGRAM;
   else
      type=SOCK_STREAM;

   s=socket(PF_INET,type,ppe->p_proto);
if( s==INVALID_SOCKET)
{
   printf(" creat socket error \n");
   WSACleanup();
   exit(1);
        }

if(bind(s,(struct sockaddr *)&sin,sizeof(sin))==SOCKET_ERROR )
    {
   printf("  socket bind error \n");
   WSACleanup();
   exit(1);
     }

if(type==SOCK_STREAM && listen(s,qlen)==SOCKET_ERROR)
     {
    printf("  socket listen error \n");
    WSACleanup();
    exit(1);
        } return s;
}
－－－－－－－－－－－－－－－
4.新建一个win32工程，添加服务器端主函数文件server.cpp
#include <winsock.h>
#include <string.h>
#include <stdio.h>
#include <stdlib.h>
#include "passive_server.C"
#pragma comment(lib,"wsock32")#define QLEN   5
#define BUFSIZE  2048
#define WAVERS    MAKEWORD(2,0)SOCKET  TCPserver(const char *service,int qlen);void main(int argc,char *argv[])
{
    char    *service = "3333";
    struct   sockaddr_in fsin;
    SOCKET   msock,ssock;
    WSADATA  wsadata;
    int      alen,cc;
    char     buf[BUFSIZE];

    switch(argc)
    {
     case 1:
     break;
     case 2:
     service=argv[1];
     break;
     default:
   printf("argment error\n");
   exit(1);
    }

    if(WSAStartup(WAVERS,&wsadata)!=0)
    {
        printf("initalize failed\n");
   WSACleanup();
exit(1);
    }

    msock=TCPserver(service,QLEN);

    while(1){
     alen=sizeof(struct sockaddr);
     ssock=accept(msock,(struct sockaddr *)&fsin,&alen);

     if(ssock==INVALID_SOCKET)
     {
           printf("initalize failed\n");
     WSACleanup();
  exit(1);
     }
     buf[0]='\n';
     while( cc=recv(ssock,buf,sizeof(buf)-1,0) ){
          buf[cc]='\0';
          printf("%s",buf);

     }
     printf("connect close... ");
     closesocket(ssock);
break;    }


}
-------------------------------------------
运行步骤，先运行服务器端文件server.cpp,然后运行客户端文件client.cpp
在客户端的窗口里输入一些文字，则会在服务器端的窗口里显示。
连续输入两个回车，则退出程序。

......疑惑ing楼主，为啥都把分给我啊？谢拉！
