Email with attachment/integerated content (Custom Preview) (no replies)

Hello all,

At the moment I am trying to make our preview window more "Smart" by including email address, subject etc. in the 'Email with attachment' button.
Nevertheless, I am encountering some problems with setting up the code.

Till now I got the following two options:

iParameterExport(iExportEmailRecipient,"Test@Mail.com")

and:

iDestination(iPDF,TempPDF)
EmailReset()
Email.Recipient[1] = "Test@Mail.com"
Email.NbRecipient = 1
Email.Subject = "Subject"
Email.Message = "Message"
Email.Attach[1] = TempPDF
Email.NbAttach = 1
EmailRunApp()

The first one does not include a subject and so on. Whereas the second one opens the windev generated message and my own created message.

Does anyone have a solution to this problem?
Regards,
Rik
