How to send mail in c windows application

To send an email from a C Windows application, you can use the Windows API function SendMail or a third-party library such as Win32 Mail or C++ Mail. Here's an example of how to use SendMail:

Using SendMail

Include the windows.h header file in your C file:
```
#include <windows.h>
```

Declare the SendMail function:

int SendMail(LPCTSTR lpszTo, LPCTSTR lpszSubject, LPCTSTR lpszBody, LPCTSTR lpszAttachment);

Call the SendMail function with the required parameters:
```
int ret = SendMail("[email protected]", "Test Email", "This is a test email", NULL);
```
In this example, lpszTo is the recipient's email address, lpszSubject is the subject of the email, lpszBody is the body of the email, and lpszAttachment is the path to an attachment file (set to NULL if no attachment is needed).

Using Win32 Mail

Include the win32mail.h header file in your C file:
```
#include <win32mail.h>
```
Create a MAIL object:
```
MAIL* mail = new MAIL();
```

Set the recipient's email address, subject, and body:

mail->SetTo("[email protected]");
mail->SetSubject("Test Email");
mail->SetBody("This is a test email");

Add an attachment (optional):
```
mail->AddAttachment("attachment.txt");
```
Send the email:
```
mail->Send();
```
Using C++ Mail
Include the cppmail.h header file in your C++ file:
```
#include <cppmail.h>
```
Create a Mail object:
```
Mail mail;
```

Set the recipient's email address, subject, and body:

mail.SetTo("[email protected]");
mail.SetSubject("Test Email");
mail.SetBody("This is a test email");

Add an attachment (optional):
```
mail.AddAttachment("attachment.txt");
```
Send the email:
```
mail.Send();
```
Note that these examples are simplified and may require additional configuration and error handling depending on your specific use case. Additionally, the SendMail function is only available on Windows XP and later versions, while Win32 Mail and C++ Mail are more widely supported.
