Hi everybody,
I m writting an application which calulates some results and send them thr e-mail.I want my VC++ program to send this mail to specified address without using Outlook Express or Microsoft Outlook...or without opening any browser window...in fact i want to send them undetected..that means user shud not know abt sending mails....plzzzzz anybody tell me how to do this..its urgent...do u think socket programming will do this?
thanx in advance
sushb4u,
Try looking into the tools by MarshallSoft, I have used their lib/dll e-mail tools for some time now with very very very good luck. They are very easy to code into your app and invisible to the user as they use their own functions and do not use Outlook or Outlook Express. They can be found at. www.marshallsoft.com
HTH Good luck
Jim
hi jim..thanks a lot for ur quick reply..but will u plz tell me in detail??i mean what shud i look for on this given url??and how can i use that tools in my code??is it necessary to load those tools on user's computer??plzzzzz reply back...its a bit urgent.
again thanks in advance.
You'll want to look at the "SEE4C" Email engine for c/c++ under the "Products" listing, it does require a dll to be on the users computer to send email in the background. There is full documentation online for reference/programmer and can be viewed. I looked and tested many email tools over a 4 month trial for one of my apps and found this one to be the best and easiest to understand and get running quickly. They do offer eval versions also.

Hi Vanaj
Well if this library be downloaded, can it be used for longer time? As it is evaluation version, i think there might be some what resisting the use for longer time.
Any comments
The following is a simple console application which sends an email...

Additionally you might take a look at http://codeproject.com/internet/csmtpconn.asp. It wraps the SMTP protocol including the mentioned MIME attachments...
Investigate MAPI, look at CDONTS.DLL
Hi Andreas,
how to execute this code??if i create new console application where to add this code??
Well...the code I posted can basically copied directly into a console application. So simply create an empty console project, add an empty *.cpp file and copy/paste the whole code into the file...
it gives this error
d:\vcprojects\m\m.cpp(165) : fatal error C1010: unexpected end of file while looking for precompiled header directive
You can also specify the Subject, an alias for the sender and receiver (besides just their e-mail addresses), and the type of message to compose (HTML, plain text).
Here's a partial example of how to send an HTML e-mail from CodeGuru:
Code:static const TCHAR szMailFrom[] = TEXT("CodeGuru");
static const TCHAR szMime[] = TEXT("content-type: text/html; charset=us-ascii");
...
wsprintf(szSend, TEXT("DATA\r\n"));
send(hSocket, (PSTR)szSend, lstrlen(szSend), 0);
recv(hSocket, (PSTR)szRecv, sizeof(szRecv) / sizeof(TCHAR), 0);
lstrcpy(szRecv, "");
// Send message header...
wsprintf(szSend, TEXT("From: %s\r\nTo: %s\r\nSubject: %s\r\n%s\r\n\r\n"),
szMailFrom, szMailTo, szMailSubject, szMime);
send(hSocket, (PSTR)szSend, lstrlen(szSend), 0);
// Send message body. Do not use wsprintf here. It only allows for 1024 bytes.
lstrcpyn(szSend, szMailBody, ARRAYSIZE(szSend));
send(hSocket, (PSTR)szSend, lstrlen(szSend), 0);
// Send message end...
lstrcpy(szSend, TEXT("\r\n.\r\n"));
send(hSocket, (PSTR)szSend, lstrlen(szSend), 0);
recv(hSocket, (PSTR)szRecv, sizeof(szRecv) / sizeof(TCHAR), 0);
Andreas' code can be used, you will need to modify it for you purpose though.
Here is a COM object that can be used to populate and send email from the VC++ application. Its very easy to use.
Just make sure you initialise the COM libraries
http://www.programmersheaven.com/zon...1168/25879.htm
Good luck.
If this is not what you are after check out the Message Application Programming Interface as suggested earlier.
Well...there was indeed missing a " in the posted code...anyway...attached is a compiled console application including the source... :cool:Quote:

Andreas,
in the code you attached why do you send line by line as opposed to the entire data buffer at once?
I am sure there is a good reason behind it, but I can't figure it out?
Thanks
Maybe because sprintf, like wsprintf (as I found out), has a limit of 1024 characters. Not always enough for the entire message body.Quote:

Makes sense to me, I will test it out.
Thanks for the reply
Well...and to provide another reason...this is old code, copied and pasted for a long time...maybe it needs a rewrite... :cool:
Really? Did not know that....thanks for pointing that out...Quote:

I was guessing that was the case. Turns out it isn't. wsprintf DOES have a 1024 limit. sprintf does not.
Here's a little test:
You'll find that the original string is printed in its entirety. The new string, however, ends at the 24th K.Code:#include <windows.h>
#include <stdio.h>
int main()
{
// Create a really large buffer...
char szBuffer[4096] = {0};
// Fill 100 elements with consecutive letters (0-99=A, 100-199=B,..., 2500-2599=Z)...
for (int i = 0; i < 26; i++)
for (int j = 0; j < 100; j++)
szBuffer[i * 100 + j] = 65 + i;
// End the string at the 2600th element...
szBuffer[2600] = 0;
// Display the string...
printf("Original String\n%s\n\n", szBuffer);
// Now, copy the string using sprintf/wsprintf...
char szBuffer2[4096];
wsprintf(szBuffer2, "%s", szBuffer);
// Display the new string...
printf("New String:\n%s\n\n", szBuffer2);
return 0;
}
K = 10th letter...
10 * 100 elements/letter = 1000...
Add the 24...
1024 elements copied into new buffer.
If you change the wsprintf line to use sprintf instead, it works fine.
That is possible, but maybe it is to do with memory..
Not really sure
Andreas,
I could run that code and i m not getting any errors..still it doesnt send any mail..i mean i gave cmd line arguments like this
"sendmail mail.infotechsa.com sushp@infotechsa.com sushp@infotechsa.com message.txt"
this doesnt send mail to abv address...plz tell me some details abt last arguement ..is it a .txt file?if yes,shud i give full path of that file on my computer?or i what else shud i enter there?
plzzzzzz reply.
Well...it sends the mail correctly, however the body is somehow empty...I need to test this further I guess...sorry about that...Quote:

Hi everybody..
all abv programs need name of smtp server...but i have only email address of receipent...so does anybosy know function or api to get smtp server name from given email address??or else can i use any standerd smtp server for any email id?if yes...plz tell me which smtp server i can use.
Thanks
Normally you would send email through your smtp server for your ISP/email account unless you are trying to hide your email address/identity/IP address. Many ISP's are not accepting email directly from a person to their smtp server unless they have a email account on that server. Many ISP are checking origin of email and if it is not from a registered email server(IP address) it won't relay email or accept the mail. With 80% of email today as spam ISP's are cracking down on people using their resources for someone elses gain.
So just send the email through your ISP's smtp server and all will work just fine.
HTH
hi...thanz a lot...but i m sorry..i didnt get much..:((
what do u mean by
"Normally you would send email through your smtp server for your ISP/email account "
ya i dont want to hide senders email address or identity...but user can enter any email id in from and to fields....so how can i get smtp server for that account's ISP??
If this is the case then you would have the user enter their smtp server address. As with most ISP's today in order to send email through their smtp server you must have a email account and log on with a user id and password this keeps people from using false return email address and using their smtp servers to relay SPAM.Quote:
ya i dont want to hide senders email address or identity...but user can enter any email id in from and to fields....so how can i get smtp server for that account's ISP??
user's stmp server address means which address?? i mean suppose i m not asking for from id (it is fixed) and i m asking for only "To" address...and user entered "abc@yahoo.com" and suppose my from id is "me@mycomp.com" then i have to use which smtp server? server for input email address or server for mycomp's address?Quote:
If this is the case then you would have the user enter their smtp server address.
i m sorry if i m creating some confusion...but plz reply:(
You would use the smtp server for "me@mycomp.com", you use the smtp server of the senders address.Quote:
"To" address...and user entered "abc@yahoo.com" and suppose my from id is "me@mycomp.com" then i have to use which smtp server? server for input email address or server for mycomp's address?
ok... thanx a lottt:) my prog is working now.
can i give any points or like something that??i m new to this forum...thats why i m asking this.
How do I rate a thread?Quote:

Well, i rly like your code but... Most servers currently need TLS/SSL support, which i do not know how to implement.
:confused:
You realise this threads over 5 years old?
Indeed.
Well, any one has tried sending emails with SMTP Authentication under VIsual C++?
It seems to be a useful feature.
The following one using visual C++ but only support the VC++ 2005 and 2008.
http://www.naughter.com/smtp.html
I like VC++ 6 better for its reliable codes and smaller code size.
"Please note that as of v2.70, the code is now for Visual C++ 2005 or later. I will not be supporting VC 6 anymore for this code, so please don't email me requesting this<gg>. Remember VC 6 is now a ten year old compiler. It's now time to upgrade to VC 2005 or VC 2008!"
Maybe someone can share the V2.70 or earlier edition while the author stopped providing aged releases.
I use this send mail vc++ code but it gives error error during call to recv<> reply:-1 - 10054 and remaing all lines.so give me solution,exactly what is the problem
I'm an old VB6 guy working my way through MSVC. At 56, it's hard to assimilate enough to write MSVC effectively before I'm retirement age! Your generous and cooperative attitude will help more people than you know. Thank you so much.
Hello. When I run the program I get an error message like this. I would be glad if you help. Thank you in advance.

Hi,
I am also using this program and it works for me if I use char (ascii), but as soon as I use unicode wchar to send the subject and the body, I get an email with a blank subject and body.
Any ideas why this is happening?
Would you mind posting the code you used with notes where you made changes? I'm new to this and need a little bit more information...Quote:
