Sample Compilation Command Lines (Visual Basic)

As an alternative to compiling Visual Basic programs from within Visual Studio, you can compile from the command line to produce executable (.exe) files or dynamic-link library (.dll) files.

The Visual Basic command-line compiler supports a complete set of options that control input and output files, assemblies, and debug and preprocessor options. Each option is available in two interchangeable forms: -option and /option. This documentation shows only the /option form.

The following table lists some sample command lines you can modify for your own use.

To

Use

Compile File.vb and create File.exe

vbc /reference:Microsoft.VisualBasic.dll File.vb

Compile File.vb and create File.dll

vbc /target:library File.vb

Compile File.vb and create My.exe

vbc /out:My.exe File.vb

Compile all Visual Basic files in the current directory, with optimizations on and the DEBUG symbol defined, producing File2.exe

vbc /define:DEBUG=1 /optimize /out:File2.exe *.vb

Compile all Visual Basic files in the current directory, producing a debug version of File2.dll without displaying the logo or warnings

vbc /target:library /out:File2.dll /nowarn /nologo /debug *.vb

Compile all Visual Basic files in the current directory to Something.dll

vbc /target:library /out:Something.dll *.vb

When compiling from the command line, you must explicitly reference the Microsoft Visual Basic run-time library through the /reference compiler option.

Tip

When you build a project by using the Visual Studio IDE, you can display information about the associated vbc command with its compiler options in the output window. To display this information, open the Build and Run, Projects and Solutions, Options Dialog Box, and then set the MSBuild project build output verbosity to Normal or a higher level of verbosity. For more information, see How to: View, Save, and Configure Build Log Files.
