The Samples Mode Frame Detail window displays detailed information about a frame collected by the profiler agent running in samples mode. The window is divided into 3 sections. The top left section displays information about the frame itself. The top right section displays the call stack. The bottom section displays a list of frames called by the current frame. Clicking on a row in the call stack section will change the display to the frame clicked on. Double clicking on a row in child frame section will change the display to the child frame clicked on. Using this mechanism you can navigate around the call tree. Many bits of information are displayed in fields in all three sections. Descriptions of these are summarized in the following tables.
