How to modify vba code in MS Access to send to all email addresses in a form, not just the first one?

Is your form using a semicolon as the delimiter between multiple email addresses?

I'm not sure how to do that.  Please see the attached screen shot of my form.

I tried adding a semicolon to the end of the email addresses in the query that the form is pulling from and it appears in the form, but the code failed and the email was not created.

Okay, I see... In the VBA you need to iterate over the email list if it there's more than one email address. The following code comes from the web site: http://www.access-diva.com/vba16.html

I think you should be able to modify the code to work within your report sub routine. See link above for more details.

Private Sub SendeMail()
     Dim rs As Recordset
     Dim vRecipientList As String
     Dim vMsg As String
     Dim vSubject As String

          Set rs = CurrentDb.OpenRecordset("SELECT * FROM qryYourQueryWitheMailAddresses ")
          If rs.RecordCount > 0 Then
              rs.MoveFirst
              Do
                  If Not IsNull(rs! YoureMailAddressField ) Then
                      vRecipientList = vRecipientList & rs! FieldThatHoldsTheeMailAddresses & ";"
                      rs.MoveNext
                 Else
                      rs.MoveNext
                 End If

             Loop Until rs.EOF

             vMsg = " Your Message here... "
             vSubject = " Your Subject here... "

             DoCmd.SendObject acSendReport, " rptYourReport ", acFormatPDF, vRecipientList, , , vSubject, vMsg, False
             MsgBox ("Report successfully eMailed!")

     Else
             MsgBox "No contacts."
     End If
End Sub

Select allOpen in new window

I tried every way that I could think of but I can't seem to get it right.  The name of the query is "qryFOL" and the field is "NMCI Email".

Hi,  I made a slight change to the loop in the sample. I uploaded a sample database with a file name extension of .txt, just change it to ".accdb".

There's caveat with the record set query which, I explain in the attached screen shot.

Code Snippet:

Sub send_email_using_query()
     Dim rs As Recordset
     Dim vRecipientList As String
     Dim vMsg As String
     Dim vSubject As String

    Set rs = CurrentDb.OpenRecordset("SELECT * FROM qryFOL ")
    vRecipientList = ""
    While Not rs.EOF
        vRecipientList = vRecipientList & rs(1) & ";"
        rs.MoveNext
    Wend
    rs.Close
    Set rs = Nothing

             vMsg = " Your Message here... "
             vSubject = " Your Subject here... "
             DoCmd.SendObject acSendForm, "sales_detail", acFormatPDF, vRecipientList, , , vSubject, vMsg, True
             MsgBox ("Report successfully eMailed!")
    
End Sub

Select allOpen in new window

This is generally a bad idea:

 While Not rs.EOF
        vRecipientList = vRecipientList & rs(1) & ";"
        rs.MoveNext
    Wend

You should instead explicitly refer to the name of the field that holds the Email addresses, instead of assuming it's going to be in a specific location in the recordset:

While Not rs.EOF
  vRecipientList = vRecipientList & rs("NameOfEmailField") & ";"
  rs.MoveNext
Wend

@Scott McDaniel (Microsoft Access MVP - EE MVE ) - Thanks for the tip. Are there situations when this approach is useful?

I deal with data sets frequently that have positional layouts, but that's mainframe and iSeries transmissions...

I'm still get an error.  Please see the attachments for details.  I also attached a screen shot of the query.  It only has one field.

If your query field name is "NMCI Email", use that instead of "0". Sorry for the confusion.

Queries in Access can easily be rewritten (and very often are), so using positional syntax to refer to a specific field in an Access query is not the best method to use. Not to say it won't work - it will - but it's far too simple for user to modify a query. Fieldnames don't change often, of course, so referring to distinctly to a Field is the preferred way of handling things in the Access world.

"Too Few Parameters" often means you've misspelled the query name, or the name of a field. In your case, you have a space after the query name in your OpenRecordset statement.

If that doesn't work, then try Compacting your database ( make a copy first).

@Scott McDaniel (Microsoft Access MVP - EE MVE ) - Thanks.

I tried with and without the space after the query name after compacting the DB, but I'm still getting the same error for the same line.

My query "qryFOL" SQL looks like:

SELECT tblContacts.Email
FROM tblContacts; 

Select allOpen in new window

My VBA Module looks like:

Sub send_email_using_query()
     Dim rs As Recordset
     Dim vRecipientList As String
     Dim vMsg As String
     Dim vSubject As String

    Set rs = CurrentDb.OpenRecordset("SELECT * FROM qryFOL ")
    vRecipientList = ""
    While Not rs.EOF
        vRecipientList = vRecipientList & rs("Email") & ";"
        rs.MoveNext
    Wend
    rs.Close
    Set rs = Nothing

             vMsg = " Your Message here... "
             vSubject = " Your Subject here... "
             DoCmd.SendObject acSendForm, "sales_detail", acFormatPDF, vRecipientList, , , vSubject, vMsg, True
             MsgBox ("Report successfully eMailed!")
    
End Sub

Select allOpen in new window

I'm still getting the same error for the below line.

Set rs = CurrentDb.OpenRecordset("SELECT * FROM qryFOL")

Select allOpen in new window

The field name in the query is named "NMCI Email".  Here is the SQL for the qryFOL

SELECT [qryContacts(FSL,FOL,ROM)].[NMCI Email]
FROM [qryContacts(FSL,FOL,ROM)]
WHERE ((([qryContacts(FSL,FOL,ROM)].Title)=[forms]![Daily Report]![SiteGroupInput]) AND (([qryContacts(FSL,FOL,ROM)].Role) Like "fol"));
