<p>Use the <b>Properties for Breakpoint > Common > Conditional</b> option to create conditional breakpoints. Where regular breakpoints suspend execution each time they are hit, a condition breakpoint evaluates an expression to determine if it is true or not. If the expression evaluates true, then program execuation is suspended and the <a href="../../reference/perspective_debug.htm">Debug</a> perpective shown. If the expression evaluates to false, execution continues. </p> |
