Backup function is as follows:

procedure TAddInModule.autosave;
    i : integer;
    filename : String;
    olddoc : WordDocument;
    PF: IPersistFile; 
   // vDoc: Word2010._Document; 
    for i:=0 to self.WordApp.Documents.Count-1 do begin
         // self.WordApp
     // Word2010._Document
     //      self.WordApp.Documents
         olddoc := self.WordApp.Documents.Item(i+1);
         filename :=  olddoc.Name; 
             filename := 'AUTOSAVE_'+olddoc.Name;                
                 if Assigned(PF) then begin
                        PF.Save( pwidechar('c:\backup\' + filename),false);                             
                         PF := nil;


In the win7 environment works well, but in win10 implementation, save the file dialog box pops up, is there any solution?

Hello Wengchi,

I assume the dialog is shown when you call PF.Save(); is this correct? Also, are you saying that you see this difference when testing the *same* Word build on Windows 7 and Windows 10?

I would check if calling PF.Save() results in setting olddoc.Saved = true. If so, I would try to set olddoc.Saved := true before saving. Depending on results of testing, I would restore or not restore olddoc.Saved after the save.

Another possibility to hide the dialog would be to intercept the WordApp.DocumentBeforeSave event; it provides the SaveAsUI parameter which you can try to set to false.
