This checks the body field on a form to see if it is empty.

Sub Click(Source As Button)
Call IsRTFNull("body")
End Sub


Function IsRTFNull(rtfield As String) As Integer

'This function tests a Rich Text field to see whether or not it is null. It returns TRUE if the field is null, and
'returns FALSE if the field is not null. It works even if the rich text field contains a file attachment,
'doclink, or OLE object but does not contain any text.

On Error Goto Errhandle

Dim uidoc As NotesUIDocument
Set uidoc = workspace.CurrentDocument

'Store the name of the field that currently has focus. Note: if this function is being called from a form button,
'currentfield will be null (because the button has the focus, and not a field). If this function is called
'from an action button, and if the cursor is in a field, then currentfield will correctly store the name
'of the field that has focus.

currentfield = uidoc.CurrentField
Call uidoc.GotoField(rtfield)
Call uidoc.SelectAll

'The next line will generate a 4407 error message if the Rich Text Field is null

'Return the cursor the the field that had focus before this function ran. If the currentfield variable is null (because a button
'or hotspot had focus, then the cursor will actually wind up getting left in the rich text field.
