The On Condition breakpoint accepts an arbitrary integer expression, and triggers when the expression evaluates to Boolean, or true. Like On Value Change, On Condition uses implicit single-stepping and is often quite slow.

To set an On Condition breakpoint:

1. In the Debugging Window, choose Windows Breakpoints or Execute Set Breakpoints.

2. If the Details pane of the Breakpoints window is not displayed, click the Add/Change Breakpoint button (the Add/Change Breakpoint button toggles to Hide Details).

3. Choose Event On Condition and type the expression you want to watch in the Event text box. For example:

a > b

4. Choose Action Stop.

5. Click on Add.

The breakpoint triggers after the line that causes the expression to have a nonzero value.
