Sending e-mail from Vis Basic

If all you want it to suspend your code for a few seconds, you could dllimport the old sleep() function. (other ways to stop code excution, but this is easy)
Most of the time it's the programmer that chooses when to send the email.
Could you re-write to simply send later when the user clicks a button to do so?
Maybe even tie in a form_closing event trigger and have it send the email then.

I don't know if you can set a property that says "E-Mail on this Date/Time".

I wonder if this would work for you, create and store the mail in the Drafts, or some other, folder. Then, you can have a process of your own that finds these mails and determines whether to send them.

Another way you can do it is to calculate the date now minus the date on the excel sheet.
Assume that sDate , which i set to 07/21/2005, is the date from the cell in your excel sheet.

Dim sDate As Date = "07/21/2005"
Dim Diff As Integer = DateDiff(DateInterval.Day, sDate, Date.Now)
If Diff > 1 Then 'If the date difference is more then 1.
'Create and send email now
End If
