4.8.2.1 Data Breakpoints Tool Window

The Data Breakpoint window provides the options to set data breakpoints and lists the added data breakpoints. Enable this window by choosing Debug → Windows → Data Breakpoints.

The Data Breakpoints toolbar has the following elements:

• 
  - provides the data breakpoint configuration window to add a new data breakpoint.
• 
  - provides the data breakpoint configuration window to edit the selected data breakpoint.
• 
  - removes the selected data breakpoint. You can invoke the same command using the Delete key.
• 
  - removes all the data breakpoints.
• 
  - enable or disable all the data breakpoints.

The Data Breakpoints window displays several columns related to the breakpoint configuration. Some of the columns are dynamically hidden based on the breakpoints configuration. E.g., if none of the breakpoints have Mask-configured, then Mask-related columns are not displayed.

The Name column has three parts:

• Checkbox - Use Checkbox to enable or disable the breakpoint.
• Icon - Glyph to represent the current state of the breakpoint. The following table describes these glyphs. If you rest the mouse on a breakpoint glyph, a breakpoint tip appears with more information. This information is helpful for error and warning breakpoints.
• Text - Displays the configured location expression for the breakpoint.
