I use MailMerge. Every time i create a SourceFile for my main documets. In Word2000/XP there is no problem but in 97 always open file dialog box appears when I open Main document. Here is my code:

=SYS(3005, 1033)
thisform.fl_error   = .t.
msg_error           = ON("ERROR")
fl_error            = .f.
ON ERROR fl_error   = .t.
thisform.nLocaleId = VAL(SYS(3004))  && Save local id
=SYS(3006,1033)                      && We will be sending instructions in English
DO WHILE TYPE("thisform.oWord") # "O" .OR. ISNULL(thisform.oWord)
   thisform.oWord             = GetObject(,"Word.Application")
   IF TYPE("thisform.oWord") # "O" .OR. ISNULL(thisform.oWord)
      thisform.oWord = CreateObject("Word.Application")
   ENDIF
ENDDO
thisform.oWord.DisplayAlerts = 0
thisform.oWord.Visible = .f.

* Here open file dialog box is raised on the screen
thisform.oWord.Documents.Open(m_name)

thisform.oWord.Caption = ALLTRIM(Blanki.Name)
WITH thisform.oWord.ActiveDocument.MailMerge
     .OpenDataSource(m_name1)
ENDWITH

ON ERROR &msg_error
thisform.fl_error = .f.
