How to: Set Conditional Breakpoints

  • 项目

You can define a condition on a breakpoint. If the condition is true, then code execution breaks at the breakpoint. If the condition is false, then code execution continues. The condition can include any variables or fields that are currently in scope. You can compare a variable or a field to another variable or field, or you can compare a variable or field to a literal value. If you compare to a literal value, then the variable or field that you use in the breakpoint condition must be of one of the following data types:

  • BigInteger

  • Boolean

  • Code

  • Decimal

  • Integer

  • Option

  • Text

    The following operators are supported in breakpoint conditions:

  • =

  • <>

  • <

  • <=

  • =

To set a conditional breakpoint

  1. In the Debugger window, do one of the following:

    • On the Home tab, in the Breakpoints group, choose Set/Clear Condition. In the Debugger Breakpoint Condition window, enter a condition.

    • On the Home tab, in the Breakpoints group, choose List. In the Debugger Breakpoint List window, enter a condition in the Condition column.

  2. Enter any conditional statement that uses variables that are in scope, constants, and supported operators.

    Note

    If you clear an existing condition, then that breakpoint is no longer a conditional breakpoint.

  3. Choose OK to close the Debugger Breakpoint List window. A plus sign is added to the red dot that is displayed in the margin.

Example

In this example, you want to set a breakpoint to debug an application. This application processes invoices in a loop, but it stops responding on a particular invoice. You set a breakpoint on the first line of code in the loop, and then you set the following condition on the breakpoint.

SalesInvoiceHeader."No." = '103007'
