Generate a concatenated string of email addresses from a list using VBScript
Use VBScript to extract email addresses from a SharePoint list of contacts and generate a concatenated string of email addresses separated by a semi-colon.
You have a SharePoint list that stores the first name, last name, and email address of contacts. You would like to use the email addresses to generate a concatenated string of email addresses separated by a semi-colon like in email@example.com; firstname.lastname@example.org; email@example.com.
Retrieve the data connection to the SharePoint list, extract all the contacts, and use their email addresses to generate a concatenated string of email addresses.
If you are using a repeating table or a people picker in a repeating table, and do not want to write code, you can also use the eval() and concat() functions to concatenate data from a repeating table.
You can accomplish this functionality as follows:
- You have a SharePoint Contacts list with the columns LastName, FirstName,
and E-mail Address.
Figure 1. SharePoint Contacts list.
- Create a New Blank Form in InfoPath.
- Create a Data Connection to the SharePoint list, select the LastName, FirstName, and Email-Address to be included in the data connection, and call the data connection Contacts. The XML data for the SharePoint list used in this solution resembles the following:
- Add a Table with Title to the InfoPath form.
- Add a List Box control to the table and bind it to the Data Connection for the SharePoint list. Use the LastName field as the Value as well as the Display name.
- Add a Text Box control to the table and name it emailAddresses.
- Modify the table and controls to resemble the following figure:
Figure 2. The InfoPath form in design mode.
- Go to Tools > Options..., click on the Design tab, and make sure that the Default programming language is set to VBScript.
- Go to Tools > Programming > On Load Event... to add an OnLoad
event handler to the form. Add the following code to the OnLoad event handler:
' Retrieve the DOM for the secondary data source connected
' to the SharePoint Contacts list
Set objContactsDOM = XDocument.GetDOM("Contacts")
' Set the namespaces to be used when retrieving XML nodes
objContactsDOM.setProperty "SelectionNamespaces", _
"xmlns:dfs=""http://schemas.microsoft.com/office/infopath/2003/dataFormSolution"" " & _
' Retrieve all the Contacts nodes
Set objContacts = objContactsDOM.selectNodes("/dfs:myFields/dfs:dataFields/dsf:Contacts")
' Loop through all the contacts
For i = 0 To objContacts.length - 1
' Retrieve email address for contact
emailAddress = objContacts(i).selectSingleNode("@E-mail_Address").text
' Generate concatenated string of email addresses
If (emailAddresses = "") Then
emailAddresses = emailAddress
emailAddresses = emailAddresses & ";" & emailAddress
' Set the value of the emailAddresses field to the concatenated string
' of email addresses
XDocument.DOM.selectSingleNode("//my:emailAddresses").text = emailAddresses
- The form should resemble the following figure when it is opened:
Figure 3. The resulting InfoPath form.
<dsf:Contacts Last_Name="Jones" First_Name="Andruw"
<dsf:Contacts Last_Name="Jones" First_Name="Chipper"
<dsf:Contacts Last_Name="Renteria" First_Name="Edgar"
<dsf:Contacts Last_Name="Smoltz" First_Name="John"
