Tracing Execution
■ With event-driven programming, it is not always obvious what the first
statement executed will be. Because of this, tracing execution is useful
in Visual Basic.
■ Use these techniques to trace the execution of code:
• Single stepping traces through each line of the procedure.
Use this when you want to see the effect that each statement produces.
• Procedure stepping executes each procedure as if it were a single
statement. Use this technique in place of single stepping when you want
to step across procedure calls rather than into the called procedure.
■ Watches are commonly used with single stepping and procedure stepping.
See: ◄Adding Watches►
■ To trace execution from the current statement:
• Press F7 to execute code to the current cursor position
• Press F8 to execute code one line at a time
• Press F10 to step across procedure calls
See: ◄Run and Debug Keys►
■ You can also set a breakpoint within a procedure before you start running
the application. When the application halts at the breakpoint, trace from
there. See: ◄Setting Breakpoints►
