Capturing Data

By default, capture is off when you open NI Spy. You can change the default through the Spy»Options dialog box.

When capture is off, the title bar of the capture window reads "NI Spy – [capture off]", and the blue arrow (start button: ) is enabled. When capture is on, the title of the capture window is "NI Spy – [capture on]", and the red X (stop button: ) is enabled.

For help on the toolbar buttons, use the context-sensitive help in the NI Spy application. Once you turn capture on, you can run your application and then return to NI Spy to view the captured calls to National Instruments drivers.

To turn capture on, select Spy»Start Capture, press <Ctrl-F8> in Windows, <Meta-F8> in Linux, or <Command-F8> in Mac OS X, or click on the blue arrow button on the toolbar:

Note  If Spy»Start Capture is grayed out, capture is already on.

To turn capture off, select Spy»Stop Capture, press <Ctrl-Break> in Windows, <Meta-Break> in Linux, or <Command-Break> in Mac OS X, or click on the red button on the toolbar:
