must port number be 25 for SMTP?
No. There are 216-1 ports, but port 25 is the most common.

i am testing a SMTP program, the program changes port from 25 to 6400 if connection failed
If your program is using port 6400, that means that the SMTP server must also be using port 6400. If the ports do not match, your program will not work.

port 6400 comes from this function:
SERVENT*pServer = getservbyname( "mail", 0);
pserver->s_port is 6400

cheers

Outlook uses CDO, which is a COM wrapper around MAPI. Search MSDN, or Google for, Outlook automation. Here are some MAPI examples.

The value from 'getservbyname' is in network byte order. If you 'ntohs' 6400 you get 25. Curious that.

plz can any one help in getting a code which writes and reads data into excel sheet using c++ or vc++..

use utilities for office. mso97.dll exports the required class to manipulate with office documents from your C++ application, get necessary classes from mso97.dll as a part of your application.

Just a tip.
If you create a text file, even a HTML page with colors and tables, and name it as .XLS, it will be read by Excel converting the HTML formatting to Excel as close as possible...I have got good results using this approach

Hi Shiva,
You have some options, but I would say the easiest is using Automation, but the drawback is Excel has to be installed on the client machine. The other option is using ADO and accessing Excel files as if they were databases, in this case Excel doesn't have to be installed, but you are limited on what you can do.
Anyways, to use Excel automation, check this article on the MSDN

Hi Friends,
I want to find out MAC address. I am using following method
GUID uuid;
CoCreateGuid(&uuid);
char mac_addr[18];
sprintf(mac_addr,"%02X:%02X:%02X:%02X:%02X:%02X",
uuid.Data4[2],uuid.Data4[3],uuid.Data4[4],
uuid.Data4[5],uuid.Data4[6],uuid.Data4[7]);
OutputDebugString(mac_addr);
But Every time it's giving the different address...

First of all, you need to understand the difference between a MAC address and a GUID. If you really don't know the difference, may be this can help:
MAC Address: A 12-byte hexadecimal address used by the media access control layer of an 802.2 connection. It is an identifier of a network node that differentiates one node from another on a network.
GUID (Globally Unique Identifier): A 16-byte (128-bit) value that uniquely identifies some entity, such as a COM class, or COM interface. Examples of GUIDs are the CLSID and the IID. A GUID is also referred to as a Universally Unique Identifier (UUID).
To learn how to get the MAC address of an ethernet adapter, fire your MSDN and search for the keywords "MAC Address". Among your search resuls, you'll find an HOWTO article regarding your query. That is the solution to your problem.

If your NIC is bound to NetBIOS, you can use this.
There's also the Win32_NetworkAdapterConfiguration WMI class.
GetAdaptersInfo() and GetIpNetTable() can also be used.

The name of your SMTP server.
I'm a bit wary of aiding you, many uses of what you want to do are dubious and you haven't explained why you want this functionality.

we have many customers, we need to tell them same news every month, it wastes time.
this app will be a good help.
the process is: read email addresses from list then send news one by one.
name of SMTP server? why does the app always say "can not connect to"?
could u give me a sample string?
i use the string "203.161.1.284" - from gethostname(), is this right?
cheers

I'd expect something like smtp.myisp.com. Your value isn't a valid IP address, FWIW. It'll be the same address that your current email client uses.
In SMTP you only need to make one connection, then you provide the list of addresses, then the message. It's worth reading the relevant RFCs (821/822 are the originals) then you'll have some understanding of the process. Creating a basic SMTP client isn't really very difficult, the complications arise when you start looking at authentication and MIME etc.

Paul,
thx for fast reply.
this is not my ip address because i don't know myself - except i copy from ipconfig.
i am testing this program now home, i use phone line to connect to the internet.
my current info is idxwc04-184.idx.com.au, could i change the string to name of SMTP server? or how can i get the name of SMTP server?
cheers

There are two ways to send email from your machine to a@b.com.
1. Do a DNS query for the MX record for b.com. Connect to the SMTP server on that address. Send your email using SMTP.
2. Connect to your local SMTP server, usually supplied as part of your Internet package by your ISP. Send your email using SMTP. This server will relay it to the b.com server.
The former is not guaranteed to work because there is a growing trend to only accept email from a whitelist of IP addresses and your home machine is unlikely to be on the whitelist whereas your ISP's SMTP server is. This is the way that viruses and spammers tend to operate.
So you need to do the latter. You will know what your local SMTP server is because your ISP will have told you and that is how your (for example) Outlook Express connection will be set up.
If you have an Internet connection that doesn't provide Email, and so doesn't provide an SMTP server then I don't see how you can reasonably expect to proceed.

I can't tell you what Outlook is using, I expect it's SMTP.

Override PreCreateWindow() in your child frame class and make sure cs.style includes WS_MAXIMIZE.
