Hi All,
I am working on a project with MFC and i need one of my windows to display the user detailes(First Name, Last Name, WorkPhone and Personal Phone) who logged into the computer. I Can use MAPI or CDO for this, access the address book, iterate thru the users and get the detailes.
Is there a way that i can use to identify the current user address book detailes instead of iterating thru the address book.
Some sample codes will help me.
Thankyou,
Kasi

Are you wanting to know how to actually use one, or implement one?

Hi
I like to show a picture in Dialog box with zooming facilities
I derived a class from CStatic
I enabled horizontal and vertical scroll bar using ModifyStyle in PreSubClassWindow
I already set other details using Scrollinfo and OnHScoll and OnVScoll
but i can't scroll image using arrows and thumb in scroll bar
how can i solve this ?

here i have a clue. but not sure weather it suits your requirement.
take the scroll bars outside your control,
in the on hscroll and on vscroll events, or on hitting the arrows,
increment/decrement the co ordinates of the image wrt. the control appropriately.
i remember, long back, when i had to display a big city map on my dialog,
i had to do the same thing for panning and zooming the map.
good luck.

You better use scrollbars in a scrollview. (it is complicated enough)

hi, i am doing some socket programming. the problem is that when i use the port number 80, then the error is 10051 which means Network is unreachable, but my network is working find. also when i use any random number for port, the error is 10061 which means Connection refused.
please guide me. here is my code ----
#include <windows.h>
#include <winsock.h>
#include <stdio.h>
#define NETWORK_ERROR -1
#define NETWORK_OK 0
void ReportError(int, const char *);
int WINAPI WinMain(HINSTANCE hInst, HINSTANCE hPrevInst, LPSTR lpCmd, int nShow)
{
WORD sockVersion;
WSADATA wsaData;
int nret;
struct in_addr addr;
addr.s_addr = inet_addr("127.0.0.1");
sockVersion = MAKEWORD(1, 1);
WSAStartup(sockVersion, &wsaData);
LPHOSTENT hostEntry;
hostEntry = gethostbyaddr((char *) &addr, 4, AF_INET);
if (!hostEntry)
{
nret = WSAGetLastError();
ReportError(nret, "gethostbyaddr()");
WSACleanup();
return NETWORK_ERROR;
}
SOCKET theSocket;
theSocket = socket(AF_INET,
SOCK_STREAM,
IPPROTO_TCP);
if (theSocket == INVALID_SOCKET)
{
nret = WSAGetLastError();
ReportError(nret, "socket()");
WSACleanup();
return NETWORK_ERROR;
}
SOCKADDR_IN serverInfo;
serverInfo.sin_family = AF_INET;
serverInfo.sin_addr = *((LPIN_ADDR)*hostEntry->h_addr_list);
serverInfo.sin_port = htons(80);
nret = connect(theSocket, (LPSOCKADDR)&serverInfo, sizeof(struct sockaddr));
if (nret == SOCKET_ERROR)
{
nret = WSAGetLastError();
ReportError(nret, "connect()");
WSACleanup();
return NETWORK_ERROR;
}
MessageBoxA(NULL, "Great, it is good", "socket Successful", MB_OK);
closesocket(theSocket);
WSACleanup();
return NETWORK_OK;
}
void ReportError(int errorCode, const char *whichFunc)
{
char errorMsg[92];
ZeroMemory(errorMsg, 92);
sprintf_s(errorMsg, "Call to %s returned error %d!", (char *)whichFunc, errorCode);
MessageBoxA(NULL, errorMsg, "socketIndication", MB_OK);
}

not sure I fully understand your issue
you've created a tcp socket client app
1) you try to connect to (local loopback address 127.0.0.1) on port 80 and get an error - do you have an ethernet adaptor, and tcp/ip set up on your machine ? - you should be able to ping yourself on 127.0.0.1 and get a valid response before you try this - then you'll need something listening on port 80 - depending on what sort of a machine, it could be IIS for example, or a server harness
2) you try a random port - unless you fix the issues at (1), its not going to work AND you would need something listening on all the ports on machine to catch the connect on a 'random' port - I dont see what a random port does for your case

thanks for the reply.
i can ping 127.0.0.1 easily and getting a valid output.but i dont know how to ping using a port. i have 2 ethernet adaptors, one is used for internet and other is spare. my internet is working find, so port 80 is also working well ??

not necessarily - you'll likely be connecting out to a web-server on port 80 on that server - unless you have something listening on your own machine on port 80 you'll get a connect fail

can u tell me the changes i should make so that it can work ?

There are no changes to make in your code. I just ran it and it works as expected.
|
|
|
|
|
which port are you using ?
if i use a port which is used by other program like utorrent, it works only when i run utorrent, else dont. if i put some other port number, it shows the errors.
i am using kaspersky internet security 2009 with windows 7rc and visual studio 2008. windows firewall is stopped. i also checked with KIS stopped, but no success.
now what to do ?

sorry, o/night here in Aus... as per Led Mike, there's nothing wrong with your code. Now you need to develop a server or grab some test code from someone's project to build one.
TCP programming involves two parts - a client, which you've got, and server, listening on a port - you still havnt indicated that you have a server listening to/on a connection, so Im not sure what sorta results you expect.

do u mean that i should write another program which listen to this port ??
also, if i want to send some information using the send() function, can i use the same port or i have to use another port for that ?

rahuljin wrote: do u mean that i should write another program which listen to this port ??
yes - the whole point of connecting to something is something must be waiting/listening on the other end ! .. maybe you could use something like http://www.aprelium.com/abyssws/[^]
rahuljin wrote: also, if i want to send some information using the send() function, can i use the same port or i have to use another port for that ?
if you are in the connected state, you have a channel open and you can send to and receive from it - depending on whats on the other end - the simplest test of your code is whats known as an echo server - it reads what you send it and sends you back the same info - see here for an example - I dont get why you're asking about another port
http://www.paulgriffiths.net/program/c/echoserv.php[^]
and here
http://www.csc.villanova.edu/~mdamian/Sockets/TcpSockets.htm[^]
I hate to say this, but it sounds like you're a little out of your depth - this sort of material is covered in lots of network programming books, and there's plenty out there on the net
Maybe you should spent some time doing a bit more research

thanks for the help. this is the first time i am writing something about tcp ip. i tried to get a book for tcp ip at my place but didn't find any.
i will try to read online.
thanks again.

'Connection refused' means that port is not active (no TCP server using the port number).
'Network is unreachable' might be meant some firewall had blocked the packet.
Can you check the firewall settings?
|
|
|
|
|
i have set it as trusted application and granted all rights.
i also have tried with firewall off, but the same result.

is there any way to give an address to bind() ?? i want that the program only except or recevice information from a specific address only. but when i try it gives an error - 10049. how should i resolve it ?
|
|
|
|
|
Post your code to bind() here, pls. And also, the IP address of the pc that you executed the program.
|
|
|
|

int getServer::getInfo()
{
ifstream ifile(path);
if(ifile)
{
ifile.getline(sss, 80);
sockVersion = MAKEWORD(1, 1);
WSAStartup(sockVersion, &wsaData);
listeningSocket = socket
(
AF_INET,
SOCK_STREAM,
IPPROTO_TCP
);
if (listeningSocket == INVALID_SOCKET)
{
nret = WSAGetLastError();
reportError(nret, "socket()");
WSACleanup();
return NETWORK_ERROR;
}
serverInfo.sin_family = AF_INET;
serverInfo.sin_addr.s_addr = inet_addr(sss);
serverInfo.sin_port = htons(23571);
nret = bind(listeningSocket, (LPSOCKADDR)&serverInfo, sizeof(struct sockaddr));
if (nret == SOCKET_ERROR)
{
nret = WSAGetLastError();
reportError(nret, "bind()");
WSACleanup();
return NETWORK_ERROR;
}
nret = listen(listeningSocket, 10);
if (nret == SOCKET_ERROR)
{
nret = WSAGetLastError();
reportError(nret, "listen()");
WSACleanup();
return NETWORK_ERROR;
}
theClient = accept
(
listeningSocket,
NULL,
NULL
);
if (theClient == INVALID_SOCKET)
{
nret = WSAGetLastError();
reportError(nret, "accept()");
WSACleanup();
return NETWORK_ERROR;
}
byteRece = recv(theClient, st, 100, 0);
if (byteRece == SOCKET_ERROR)
{
nret = WSAGetLastError();
reportError(nret, "send()");
WSACleanup();
return NETWORK_ERROR;
}
MessageBoxA(NULL, st, "Server Status", MB_OK | MB_ICONEXCLAMATION);
closesocket(theClient);
closesocket(listeningSocket);
WSACleanup();
return NETWORK_OK;
}
in ip.txt, if i put the ip --- 127.0.0.1 for same pc, it works or if i set the instruction ---
serverInfo.sin_addr.s_addr = INADDR_ANY;
if i put an ip address of other pc in the network, then bind() shows an error -- 10049. the ip is like 192.168.250.201.
|
|
|
|
|
serverInfo.sin_addr.s_addr = inet_addr("127.0.0.1");
...
nret = bind(listeningSocket, (LPSOCKADDR)&serverInfo, sizeof(struct sockaddr));
It is common sennse always succeeds above.
But,
serverInfo.sin_addr.s_addr = inet_addr("192.168.250.201");
...
nret = bind(listeningSocket, (LPSOCKADDR)&serverInfo, sizeof(struct sockaddr));
will succeeds only when this server program is executed on the pc which has IP address '192.168.250.201' exactly.
Note that bind() address is not client address but server address. So you cannot choose client by bind() and you should check accept()'ed client address by means.
Another situation, you have some local IP address and global IP address 10.0.0.1 by PPPOE, you may not wait for connection on 10.0.0.1 usually, because 10.0.0.1 address is owned by a router which connecting another network. Then you should wait on your local IP address and make change the router settings, for example DMZ or static routing, which 10.0.0.1 in-bound packets can route to your local IP address. In this case, in fact, it is not a programming issue but the network setting issue.
