Which Scripting Language Allows for the Use of the Component Object Model COM )?


Angela Bailey

The Component Object Model (COM) is a platform-independent, binary interface standard introduced by Microsoft for software componentry. It enables software components to interoperate and communicate with each other across different programming languages and frameworks. While COM itself is not a scripting language, it can be used with various scripting languages to create powerful and flexible applications.

Scripting Languages Compatible with COM

Several scripting languages support the use of COM, allowing developers to leverage the functionality provided by COM components. Let’s take a closer look at some of these scripting languages:

1. VBScript

VBSscript is a lightweight scripting language developed by Microsoft. It was designed as a successor to the older Visual Basic for Applications (VBA) language. VBScript supports COM natively, making it an excellent choice for working with COM components in Windows environments.

2. JScript

JScript, also known as JavaScript, is a widely-used scripting language primarily used for web development. It can also interact with COM components through the use of ActiveX objects, which are essentially COM objects exposed to the JavaScript environment.

3. PowerShell

PowerShell is a command-line shell and scripting language developed by Microsoft specifically for system administration tasks. It has built-in support for working with COM objects, allowing administrators to automate various tasks using existing COM components.

4. Perl

Perl is a powerful and flexible scripting language commonly used in web development, system administration, and network programming. Perl provides modules like Win32::OLE that enable interaction with COM objects, making it possible to utilize their functionality within Perl scripts.

The Benefits of Using COM with Scripting Languages

Using scripting languages in conjunction with COM offers several benefits:

  • Access to Powerful Functionality: COM components often provide robust and specialized functionality that can be accessed and utilized through scripting languages, enabling developers to leverage existing code and libraries.
  • Interoperability: COM’s platform-independent nature allows components written in different languages to communicate seamlessly, making it easier to integrate disparate systems and technologies.
  • Rapid Development: Scripting languages are generally more concise and expressive than traditional programming languages. Combining them with COM allows developers to quickly prototype and build applications with minimal overhead.
  • Flexibility: Scripting languages are highly flexible, allowing developers to experiment and iterate faster. By incorporating COM, developers can extend the capabilities of their scripts by tapping into a vast ecosystem of pre-existing components.


In conclusion, several scripting languages like VBScript, JScript, PowerShell, and Perl support the use of the Component Object Model (COM). These scripting languages allow developers to harness the power of COM components for enhanced functionality, interoperability, rapid development, and increased flexibility in their applications. By combining the strengths of both scripting languages and COM, developers can create robust solutions that leverage existing code while benefiting from the flexibility provided by scripting languages.

The ability to use COM with scripting languages opens up a world of possibilities for software development across various domains. Whether you are building web applications, automating system tasks, or working on network programming projects, the combination of scripting languages and COM provides a powerful toolkit for creating efficient and versatile applications.
