Hi ppl, I''m writing a small program using MFC and use various modeless dialogs which are created by the main dialog window. All these dialogs show/utilize the data of a database object that gets loaded at initialization. My problem is that I do not know where to place the database object. Should it be global ? Statically declared somewhere and accessed through some class ? Declared in the main dialog and then accessed by the modeless dialogs through the passed ''this'' pointer of the main dialog ? Registering the dialogs at the database by using inheritance ? What is the best solution (putting the ones mentioned aside) ? Thanks in advance.
