The Digibiz Email Form with TinyMCE is a datatype which makes it easy to store all the email fields in a single property of a documenttype. It uses the TinyMCE editor to format the e-mail and if the send checkbox is checked the sender name, sender e-mail, subject and receiver e-mail become mandatory.
The DigibizEmailForm.dll contains a DEF_Helper class with some static methods which make it easy to get all the email fields. For a good example you can download the DemoProject.
