Add ... to show users that a non modal dialog follows?

I have a simple question.

I have a lot of menuitems and buttons in my application. I try to remember to add ... in the caption to indicate that a modal dialog is followed.

But should I also add those dots for a non modal dialog. I try to search in Google but cannot开发者_C百科 find any clear answer. I use Win32 and Delphi.

The ... implies that some further input is required to complete the action of the menu item.

So, "Save" means that the menu item will cause the document to save, whereas "Save..." implies that the user will need to enter the name, or choose a file format or something before the file will be saved.

Typically the further input is entered in a popup modal dialog, but (a) not every modal dialog is a prompt for further information, and (b) hypothetically some other input mechanism could be used.

The '...' implies that the user will be given the opportunity to back-out of the operation.

This was in a user interface guideline book I read back in 1995, I can't seem to find a definitive confirmation online anymore.

I'd say that this depends strongly on your personal taste. I add ... whenever any new window is opened, be it modal or non-modal, to indicate to the user that he has to expect some other window to appear.

My guess is that there should be some Microsoft UI Guidelines document about that, but neither have I ever looked for something like that nor do I know of one.
