The Forms Instance Manager Class is a programming tool to assist VBA developers in the use
and management of instanced forms in MS Access (or other MS Office applications that support instanced forms).
The Forms Instance Manager (FIM) is a VBA class object that globally manages a collection of form instances.
The FIM overcomes the major obstacles associated with using instanced forms –
the difficulty in controlling the lifetime of an instanced form, and the inability to reliably refer to a form instance
through the VBA host application's
The Forms Instance Manager (FIM) enables a programmer to:
- Uniquely identify each form instance, including multiple instances of the same form.
- Manage any number of form instances through a single global variable.
- Fully control the lifetime of each form instance.
- Use familiar syntax to add, remove, and count form instances.
- Reference form instances using numeric or string indexes.
- Automatically generate a unique string ID based on a form's name.
- Set the focus to any form instance with a single statement.
- Find groups of instanced forms with similar names.
