You can go through my article Numeric Edit Control[^] to find an answer to your problem. You can also download the complete source code with the article and use it as it is to save your time (of course only if you are working with MFC).

Does the SMTP server exist that you are referencing? If so, is it using port 25 for the SMTP service?

I would be inclined to ask my ISP about their SMTP server. If you are doing this from within a company, then ask the network administrator.

must port number be 25 for SMTP?

i am testing a SMTP program, the program changes port from 25 to 6400 if connection failed

it looks strange.

cheers

No. There are 2¹⁶-1 ports, but port 25 is the most common.

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

i wait for my ISP.
thanks, i will post new thread if need help

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.

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 Cool | :cool:

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 i create a Array template,how to provide the function of insert the data into the Array?

29-Apr-04 2:35

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.

Go through the MFC sources, you will find information regarding this in the CArray class's source code.

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.
