The second column displays the time at which the item was captured, either in elapsed time
or clock time. By default, DebugView shows the number of seconds since the first debug
record in the display was captured, with the first item always being 0.00. This can be helpful
when debugging timing-related problems. This timer is reset when the display is cleared.
Choose Clock Time from the Options menu if you prefer that the local clock time be displayed
instead. Additionally, choose Show Milliseconds from the Options menu if you want
the time stamp to show that level of granularity. You can also configure the time display with
command-line options: /o to display clock time, /om to display clock time with milliseconds,
and /on to show elapsed time.
Tip Changing the Show Milliseconds setting doesn’t change the display of existing entries.
You can refresh these entries by pressing Ctrl+T twice to toggle Clock Time off and back on. All
entries will then reflect the new setting for Show Milliseconds.
The debug output is in the Debug Print column. For user-mode debug output, the process
ID (PID) of the process that generated the output appears in square brackets, followed by the
output itself. If you don’t want the PID in the display, disable the Win32 PIDs option in the
Options menu.
You can select one or more rows of debug output and copy them to the Windows clipboard
by pressing Ctrl+C. DebugView supports standard Windows methods of selecting multiple
rows such as holding down Shift while pressing the Up or Down arrow keys to select
consecutive rows, or holding down Ctrl while clicking nonconsecutive rows.
By default, the Force Carriage Returns option is enabled, which displays every string passed
to a debug output function on a separate line, whether or not that text is terminated with a
carriage return. If you disable that option in the Options menu, DebugView buffers output
text in memory and adds it to the display only when a carriage return is encountered or the
memory buffer is filled (approximately 4192 characters). This allows applications and drivers
to build output lines with multiple invocations of debug output functions. However, if output
is being generated from more than one process, the output can be jumbled together, and
the PID that appears on the line will be that of the process that output a carriage return or
filled the buffer.
If the text of any column is too wide for that column, move the mouse over it and the full
text will appear in a tooltip.
Debug output is added to the end of the list as it is produced. DebugView’s Autoscroll
feature (which is off by default) scrolls the display as new debug output is captured so that
the most recent entry is visible. To toggle Autoscroll on and off, press Ctrl+A or click the
Autoscroll icon in the toolbar.
