HOWTO: How to Send/Receive E-Mail Messages with Visual Basic

MORE INFORMATION

1. Start up Visual Basic and select a Standard EXE project. On the Project menu, click Components, and select Microsoft MAPI Controls. There are two new icons displayed on the toolbar. Both icons have envelopes; one with a key, the other with a paperclip. These are your MAPI controls.
2. Add these MAPI controls to your form.
3. Add the following items to the form:
   

         Four Labels
         Four CommandButtons
         Four TextBoxes
   
   						

   The label captions are as follows:
   

         Label1.Caption = "To:"
         Label2.Caption = "SUBJECT:"
         Label3.Caption = "FROM:"
         Label4.Caption = "MESSAGE:"
   
   						

4. Place the TextBoxes in numerical sequence with these labels (side-by- side for labels 1 thru 3, and below for label 4).
5. Label the CommandButtons as follows:
   

       
         Command1.Caption = "<<"
         Command2.Caption = ">>"
         Command3.Caption = "Connect"
         Command4.Caption = "Send"
         Command5.Caption = "Close Session"
    
   						

6. Add the following code to your form:
   

         Option Explicit
         Dim X As Long
   
         Private Sub Command1_Click()
   
           If X - 1 < 0 Then
             Else
           X = X - 1
           MAPIMessages1.MsgIndex = X
           Text1.Text = MAPIMessages1.RecipDisplayName
           Text2.Text = MAPIMessages1.MsgSubject
           Text3.Text = MAPIMessages1.MsgOrigDisplayName
           Text4.Text = MAPIMessages1.MsgNoteText
           End If
   
         End Sub
   
         Private Sub Command2_Click()
   
           If X + 1 > MAPIMessages1.MsgCount Then
           X = MAPIMessages1.MsgCount
             Else
           X = X + 1
           MAPIMessages1.MsgIndex = X
           Text1.Text = MAPIMessages1.RecipDisplayName
           Text2.Text = MAPIMessages1.MsgSubject
           Text3.Text = MAPIMessages1.MsgOrigDisplayName
           Text4.Text = MAPIMessages1.MsgNoteText
           End If
   
         End Sub
   
         Private Sub Command3_Click()
           MAPISession1.SignOn
           MAPIMessages1.SessionID = MAPISession1.SessionID
           MAPIMessages1.Fetch
             If MAPIMessages1.MsgCount > 0 Then
               Text1.Text = MAPIMessages1.RecipDisplayName
               Text2.Text = MAPIMessages1.MsgSubject
               Text3.Text = MAPIMessages1.MsgOrigDisplayName
               Text4.Text = MAPIMessages1.MsgNoteText
               Command4.Enabled = True
             Else
               MsgBox "No messages to fetch"
               MAPISession1.SignOff
               Command4.Enabled = False
             End If
   
         End Sub
   
         Private Sub Command4_Click()
   
           MAPIMessages1.Compose
           MAPIMessages1.RecipDisplayName = Text1.Text
           MAPIMessages1.MsgSubject = Text2.Text
           MAPIMessages1.MsgNoteText = Text4.Text
           MAPIMessages1.ResolveName
           MAPIMessages1.Send
   
         End Sub
   
         Private Sub Command5_Click()
