How to: Control Messages View
With Spy++, you have considerable control over the content of a Messages View window. You can start and stop displaying the messages at any time, and you can specify:
Which message types you want to see.
Which windows you want to monitor.
The display format for message lines.
These settings are available from the Message Options Dialog Box, and they apply only to the active Messages View window. To open this dialog box, choose Log Messages from the Spy menu.
Three tabbed panes of message options are available. For further information, see Windows Tab, Message Options Dialog Box, Messages Tab, Message Options Dialog Box, and Output Tab, Message Options Dialog Box.
