Sending emails

[Ian Swift]

I was wondering how I would go about getting a VC++ application to send a file via email when I click a button.

Thanks

Hi!

Here's one of the methods to send an e-mail through a VC program. U can add the code in the Button Clicked Event.Make use of the MAPI32 Dll and header files mentioned below for the same. Refer online help for more info.

#include <windows.h>
#include <mapi.h>

LPMAPILOGON lpfnMAPILogon;
LPMAPISENDMAIL lpfnMAPISendMail;
LPMAPILOGOFF lpfnMAPILogoff;

MapiRecipDesc recipient ={0, MAPI_TO,"Suganya Swaminathan", "SMTP:suganyas@aditi.com", 0, NULL};

MapiMessage message ={0, "Greetings", "Hello, Ms.Sukanya!\n",NULL, NULL, NULL, 0, NULL, 1, &recipient, 0, NULL};

LHANDLE lhSession;
HANDLE hMAPILib;

hMAPILib = LoadLibrary("MAPI32.DLL");
lpfnMAPILogon =(LPMAPILOGON)GetProcAddress(hMAPILib, "MAPILogon");
lpfnMAPISendMail =(LPMAPISENDMAIL)GetProcAddress(hMAPILib, "MAPISendMail");
lpfnMAPILogoff =(LPMAPILOGOFF)GetProcAddress(hMAPILib, "MAPILogoff");
(*lpfnMAPILogon)(0, NULL, NULL, MAPI_NEW_SESSION
, 0,&lhSession);
(*lpfnMAPISendMail)(lhSession, 0, &message, 0, 0);
(*lpfnMAPILogoff)(lhSession, 0, 0, 0);
AfxMessageBox("Message to the Suganya sent.\n");
FreeLibrary(hMAPILib);

Do let me know if this works.

I tried your program, I am not getting any errors or warnings (except: HMODULE instead of HANDLE for hMAPILib ), but it's not working.
When I tried to with HANDLE, I got an error of conversion from void* to HINSTANCE* not possible. So, I made that to HMODULE, then I am not getting any errors but it's not working also. let me any wrong...if it has
