īlock comments delimit a region of source code which may span multiple lines or a part of a single line. The flexibility provided by comments allows for a wide degree of variability, but formal conventions for their use are commonly part of programming style guides.Ĭomments are generally formatted as either block comments (also called prologue comments or stream comments) or line comments (also called inline comments). The syntax of comments in various programming languages varies considerably.Ĭomments are sometimes also processed in various ways to generate documentation external to the source code itself by documentation generators, or used for integration with source code management systems and other kinds of external programming tools. They are added with the purpose of making the source code easier for humans to understand, and are generally ignored by compilers and interpreters. In computer programming, a comment is a programmer-readable explanation or annotation in the source code of a computer program. An illustration of Java source code with prologue comments indicated in red and inline comments in green. The compiler will include trace or debug code in the executable.įor example, the following compiler instruction entered on the command line would include your tracing code in a compiled executable:įor Visual Basic: vbc -r:System.dll -d:TRACE=TRUE -d:DEBUG=FALSE MyApplication.vbįor C#: csc -r:System.dll -d:TRACE -d:DEBUG=FALSE MyApplication.For comments in Wikipedia markup, see Help:Wiki markup#Character formatting and WP:COMMENT. Set a conditional compiler switch on the command line. To compile instrumented code using the command line Clear the check boxes for settings you want to disable. In C#, click the Build tab in the left pane of the property page, then select the check boxes for the compiler settings you want to enable. Select the check boxes for the compiler settings you want to enable. In Visual Basic, click the Compile tab in the left pane of the property page, then click the Advanced Compile Options button to display the Advanced Compiler Settings dialog box. Right-click the project node in Solution Explorer.Ĭhoose Properties from the shortcut menu. To change compile settings from the property pages dialog box #CONST (for Visual Basic) and #define (for C#) ![]() ![]() You can specify the compiler settings for your application in several ways: ![]() Some release builds for production deployment might contain neither most debugging builds contain both. Thus, there are four types of build: Debug, Trace, both, or neither. You can have either the Trace or Debug conditional attribute turned on for a build, or both, or neither. dll) if the Trace conditional attribute is false, the trace statements are not included. For example, if the conditional attribute for tracing is true, all trace statements are included within an assembly (a compiled. If you do not enable the TRACE directive, all tracing code is ignored during compilation and is not included in the executable code that you will deploy.īoth the tracing and debugging methods have associated conditional attributes. This allows tracing code to be compiled into the release version of your application. However, to include tracing features in a deployed application, you must compile your instrumented applications with the TRACE compiler directive enabled. While you are debugging an application during development, both your tracing and debugging output go to the Output window in Visual Studio.
