Visual Basic 2005 in a Nutshell (In a Nutshell (OReilly))

Class

System.Diagnostics.Debug

Syntax

Debug.WriteLineIf(condition, output[, category])

condition (required; Boolean)

Condition that must evaluate to true before output is sent to the debug listeners.

output (required; String or Object)

The string to be sent to the debug listener outputs. For Objects, the ToString method is used to access the string content.

category (optional; String)

A category name used to group output messages; the text is attached to the beginning of output.

Description

The WriteLineIf method prints text to the Output Window and other debug listeners, followed by a line break, when an application runs in the design-time environment, provided that condition is TRue.

Usage at a Glance

The Debug class features only work in the design-time environment; the statement has no effect in a compiled application. You do not have to remove Debug-related features from your code before release.
