Sending Email
Introduction
During the software development, I have seen many applications that requires incorporating email support. I remember, once I was to develop an application, which sends emails at the specific time to specific people with the customized messages. For that I developed a COM service that used MAPI. MAPI, i.e. Messaging Application Programming Interface, is the standard messaging architecture and a complete set of functions and object-oriented interfaces. Here I have an Email component, a COM DLL, which is a set of messaging functions that helps you create messaging-enabled applications. This COM component uses Simple MAPI to achieve that.
Note: MAPI is used by various industry-standard e-mail clients, such as the Microsoft Exchange client, all versions of Microsoft Outlook and Outlook Express, including QUALCOMM Incorporated (Eudora) and Netscape Communications Corporation. So you can use this component with these client applications also.
Component Design
The CLSID of the Email component is CLSID_Mail and it has only one interface IMail with the interface ID IID_IMail.
CMail is the implementation class and contains following data members:
m_MAPILogon
Function pointer for MAPILogon
m_MAPISendMail
Function pointer for MAPISendMail
m_MAPISendDocuments
Function pointer for MAPISendDocuments
m_MAPIFindNext
Function pointer for MAPIFindNext
m_MAPIReadMail
Function pointer for MAPIReadMail
m_MAPIResolveName
Function pointer for MAPIResolveName
m_MAPIAddress
Function pointer for MAPIAddress
m_MAPILogoff
Function pointer for MAPILogoff
m_MAPIFreeBuffer
Function pointer for MAPIFreeBuffer
m_MAPIDetails
Function pointer for MAPIDetails
m_MAPISaveMail
Function pointer for MAPISaveMail
IMail have the following functions:
IsMapiInstalled
Checks if the MAPI is installed on the system. It searches Win.INI file for the MAPI key. If found it returns S_OK.
InitMapi
After checking the through IsMapiInstalled, it initializes the MAPI function pointers. Method should be called once before using the component.
put_strProfileName
Takes the name of the outlook profile name you are using to send the email.
put_strEmailAddress
Sets the recipient email address. You can specify more than one comma (,) separated recipient addresses.
put_strRecipient
Sets the name you want to specify for the recipients, sets the email names of the sender – it may be different from your specified profile email address.
put_strSubject
Sets the subject of the email.
get_strSubject
Returns the email subject.
put_strMessage
Sets email message text.
get_strMessage
Returns message text.
put_strAttachmentFilePath
Sets the email attachment with the full path like “c:\abc.txt”.
get_strAttachmentFilePath
Returns the path of email attachment.
put_strAttachmentFile
The display name of the attachment (Sample.txt), by default, it’s the same as that specified in put_strAttachmentFilePath.
get_strAttachmentFile
Returns the attachment file name.
Logon
Opens a new logon session if not already opened, using specified outlook profile, name and the profile password, you must logon before sending the email. I have set password to NULL assuming that the profile you will specify have NO password, but you can specify your own password. Automatically called by Send method.
Logoff
Logs off, and closes the session. Automatically called by Send method after sending the email.
Send
Sends the email, requires valid outlook profile name, recipient email address and a login session to send email.
Steps to execute the demo project
The demo project demonstrates the way you can use the component to send an email. In order to execute the demo project, the following settings are required:
Step 1: You must have some valid Output Express email account or create one named TestProfile.
You can create an email profile in Express from Tools>Accounts menu. This will open Internet Accounts property sheet. On the tab All, click the button Add and then Mail. A wizard will let you create an email account, specify the valid email address. For hotmail account, wizard automatically sets the names of email servers.
After successfully creating the account, select the account name from the list in All tab (for hotmail account, the default account name is Hotmail). Open account properties by pressing Properties button and change the account name from default name (say Hotmail) to TestProfile.
Step 2: Register the DLL
All COM DLLs required to be registered. After copying the DLL source code, you can register the DLL by right clicking the DLL and selecting Register DLL or Register COM component option, or simply by double clicking the DLL. Compiling the DLL code in Visual Studio will automatically register the DLL.
Step 3: Logged on to the net
Make sure you are logged on to the net. If not, outlook will fail to deliver the email, however, you can still check the composed email in your outbox.
How to send email?
After specifying the information in the dialog box, click the Send button. A warning message will be displayed, click Send button.
Note:The warning dialog is displayed because of the security constraints. If you want to get rid of this dialog box, then you will have to use Extended MAPI instead of simple MAPI.
Here is the method CTestEmailDlg::OnSend method, which is used to pass the user specified information to the email object and call the IMail::Send method after setting everything.
