Hi,

I have an MDI application. My document class manages a projectfile. In that projectfile the user can change files, add files, etc...

Now when the user closes the document I want to ask him if he want to save the files he has changed. In many applications I saw a MessageBox with the "Yes to All" button. I want to use this, so that the user doesn't have to answer for each file.I have checked the Message-box Types but I can't find one for this button.

Do I have to create my own MessageBox or is there someone who knows a solution for this ?
