I know you can email reports from Microsoft Access databases. 

But, know I am programming using Visual Basic 6 and need to know how I can email.

How do I email from Visual Basic 6 application?

What sort of email server will you be sending email through?  MS Exchange?

I will be using Outlook which is set up on our network.

One of the easiest ways to send email using Exchange from VB6 in my
experience is to use the Exchange Pickup Folder.  You can also use a
number of COM components such as CDONTS and there are a number of
third-party components that provide more robust functionality.  I'll
just demonstrate the Pickup Folder here.

Essentially, you just write a text file to the the Pickup Folder and
Exchange does the rest automagically.  The name of the file does not
matter, so use whatever filename will help you track your messages.

On any computer with the standard IIS installation, the folder is
C:\Inetpub\mailroot\Pickup.  You will only have the Inetpub\mailroot
folder if you selected the SMTP Service option when installing IIS on
your computer.  You can use the Add or Remove Programs applet in the
Control Panel to add this option if it is missing.  If IIS is running
on a remote computer, write the file to the corresponding folder on
the remote computer.  Make sure the Simple Mail Transfer Protocol
(SMTP) service is running on the computer where you are writing your
text files when you test your program.  WARNING! Don't leave that
service up and running on a computer that is not behind a firewall or
it could be maliciously used by other computers to relay spam for
them.

Creating and writing to a text file from VB6 is a snap.  The code
looks the same in Access 2000 and later versions by the way.  Here's a
sample that I've put in a generic VB button click Sub.  Note that in a
filespec, we replace each backslash "\" with a double-backslash "\\"

Private Sub Command1_Click()
    Open "c:\\somefolder\\hello.txt" For Output As #1
    Print #1, "hello world!"
    Close #1
End Sub

So using this method, we just write a email message out to the Pickup Folder.

Private Sub Command1_Click()
    Open "c:\\Intepub\\mailroot\\Pickup\\mymsg.txt" For Output As #1
    Print #1, "x-sender: jason@mycorp"
    Print #1, "x-receiver: leslie@mycorp"
    Print #1, "From: jason@mycorp"
    Print #1, "To: leslie@mycorp"
    Print #1, "Subject: Results are in."
    Print #1, "We have won!"
    Close #1
End Sub

For clarity, keep in mind that Outlook is an email client or email
reader.  Exchange is the email service provider or mail delivery
system.  You are using VB to send email through Exchange, not Outlook.
 It is not necessary to have Outlook installed to send email through
Exchange, no matter what method one uses.

Do I have to purchase MS Exchange? Is it something I would purchase at Best Buy?

You said "I will be using Outlook which is set up on our network." and
I was just clarifying.  More exact would have been "I will be using
Exchange which is set up on our network."

You don't need to purchase anything.  If you are on a network and use
Outlook to send and receive email, then just install IIS on your local
computer (including the SMTP mail portion which is not normally
included by default during install).  Then follow the instructions I
gave in the last comment.

You can do this easily with MAPI in VB (it uses your default email
client; ie sounds like outlook for you, but this code will also work
with other popular clients like thunderbird, etc ...) -- you do not
need to go through the pain of setting up ISS simply to send emails! 
Here's the solution:

1) Add the Microsoft MAPI Controls 6.0 to your project (depending on
your version of VB, you can do this under something like
Project-->Components)

2) Add a MAPISession object (named 'MAPISession1') and a MAPIMessages
object (named 'MAPIMessages1') (the default properties should be
fine).

3) Add the following code to your project:

Private Sub LogonEmail()
    MAPISession1.SignOn
    MAPIMessages1.SessionID = MAPISession1.SessionID
End Sub

Private Sub SendMail(ToEmail$, Subj$, Body$)   
    MAPIMessages1.Compose
    MAPIMessages1.RecipDisplayName = ToEmail
    MAPIMessages1.MsgSubject = Subj
    MAPIMessages1.MsgNoteText = Body
    MAPIMessages1.ResolveName
    MAPIMessages1.Send
End Sub

Private Sub LogoffEmail()
    MAPISession1.SignOff
End Sub

4) To use, call LoginEmail() and then call SendMail with the
appropriate to, subj, and body fields to send email.  When you're done
sending email just call LogoffEmail() to sign off of the session. 
Enjoy!

Thanks you very much dound-ga!!!! This works great!!!

Is it possible to attached a report to the email?

Yes, but it is somewhat harder.  If the report is text-based, I would
consider appending it to the body of the email.  If you need to
actually send attachments though, then I suggest you read
http://www.ilook.fsnet.co.uk/vb/vbmapi.htm -- this page has a great
overview and example use of a function "AddAttachment" and is public
domain.

Glad to help; hopefully this has answered your questions.

you can create outlook express object and send email through it.
