A Message Bar is a modeless bar at the top of the main SOLIDWORKS window
that provides
information
specific to the active document.
There are four types
of Message Bars:
- Information
- Acknowledgment
- Warning
- Error
A Message Bar can open in several situations. It is usually a warning about a
document state, for example, that your changes will not be saved because you did not
check out the document. A Message Bar never auto-dismisses - you must manually dismiss
it.
