Platform Invocation Services
Platform Invocation Services, commonly referred to as P/Invoke, is a feature of Common Language Infrastructure implementations, like Microsoft's Common Language Runtime, that enables managed code to call native code.
Architecture
Overview
Two variants of P/Invoke currently in use are:
Explicit
- This definition is the "Explicit" part
Implicit
- i.e. Adding/removing/re-ordering structures in a native header will be transparently supported so long as the structure member names did not also change.

Project Setup and Hello World - P/INVOKE WITH C# AND C++ TUTORIAL #1
I demonstrate a simple Hello World application using P/Invoke inter-op. First, I expose a C++ function in a dynamic link library (DLL). Then, I import the C++ function from the DLL into a C# console application and call it. Lastly, I demonstrate how you can automatically output your dll and console application to the same directory to speed up development. C++ is powerful. Whether you need to manage resources more efficiently or you need to use a library that is only available in C++, there are times where you must use C++ in your C# application. P/Invoke is a powerful way to accomplish this. In this series, I will be demonstrating the power of P/Invoke inter-op and showing how you can implement P/Invokes into your own application.

Marshaling Classes - P/INVOKE WITH C# AND C++ TUTORIAL #4
I demonstrate how to marshal classes to and from C++ and C#. Although it is not possible to directly marshal classes, I demonstrate how to marshal a C++ class pointer to C#. The C# application then sends the pointer back to C++ to invokes methods on the class and send results back to the C# application. This allows the C# application to use the C++ class's functionality.

Summary: Learn how to bridge the gap between managed and unmanaged code in C# using Platform Invocation Services (P/Invoke). Explore the basics of P/Invoke, its syntax, usage, and considerations for interoperability between managed and unmanaged code.
---
When developing applications in C, you may come across situations where you need to interact with native libraries or system APIs written in languages like C or C++. This is where Platform Invocation Services (P/Invoke) comes into play. P/Invoke allows managed code in C to call functions implemented in unmanaged code.
What is P/Invoke?
Platform Invocation Services (P/Invoke) is a mechanism in .NET that enables managed code to call unmanaged code. It serves as a bridge between managed and unmanaged code, allowing interoperability between the two worlds. With P/Invoke, you can leverage functionality implemented in unmanaged libraries from your managed C code.
Basic Syntax of P/Invoke
To use P/Invoke, you need to declare the external functions you want to call from unmanaged code within your C code. This is done using the DllImport attribute. Here's a basic syntax example:
[[See Video to Reveal this Text or Code Snippet]]
In this example, we're calling the MessageBox function from the user32.dll library, commonly used for displaying message boxes in Windows.
Parameters and Return Types
When declaring external functions with P/Invoke, it's crucial to match the parameters and return types correctly. Pay attention to data types and marshaling behavior between managed and unmanaged code. .NET provides various data type marshaling options to ensure compatibility between managed and unmanaged code.
Considerations and Best Practices
While P/Invoke offers a powerful way to access unmanaged code from managed code, there are some considerations and best practices to keep in mind:
Performance: P/Invoke calls incur overhead compared to managed code. Minimize the frequency of calls and consider batching operations where possible.
Error Handling: Ensure proper error handling, especially when calling functions that return error codes. Use appropriate mechanisms to handle exceptions and errors gracefully.
Marshaling: Pay attention to data type marshaling and ensure compatibility between managed and unmanaged code. Use the appropriate marshaling attributes and techniques to handle complex data types and structures.
Security: Be mindful of security implications, especially when interacting with unmanaged code. Validate inputs and sanitize data to prevent security vulnerabilities such as buffer overflows or injection attacks.
Conclusion
Platform Invocation Services (P/Invoke) in C provides a powerful mechanism for accessing functionality implemented in unmanaged code from managed code. By understanding the basics of P/Invoke syntax, parameter passing, and considerations for interoperability, developers can effectively bridge the gap between managed and unmanaged environments, unlocking a wide range of capabilities for their applications.

In this example, we're calling the MessageBox function from the user32.dll library, commonly used for displaying message boxes in Windows.
Parameters and Return Types
When declaring external functions with P/Invoke, it's crucial to match the parameters and return types correctly. Pay attention to data types and marshaling behavior between managed and unmanaged code. .NET provides various data type marshaling options to ensure compatibility between managed and unmanaged code.
Considerations and Best Practices
While P/Invoke offers a powerful way to access unmanaged code from managed code, there are some considerations and best practices to keep in mind:
Performance: P/Invoke calls incur overhead compared to managed code. Minimize the frequency of calls and consider batching operations where possible.
Error Handling: Ensure proper error handling, especially when calling functions that return error codes. Use appropriate mechanisms to handle exceptions and errors gracefully.
Marshaling: Pay attention to data type marshaling and ensure compatibility between managed and unmanaged code. Use the appropriate marshaling attributes and techniques to handle complex data types and structures.
Security: Be mindful of security implications, especially when interacting with unmanaged code. Validate inputs and sanitize data to prevent security vulnerabilities such as buffer overflows or injection attacks.
Conclusion
Platform Invocation Services (P/Invoke) in C provides a powerful mechanism for accessing functionality implemented in unmanaged code from managed code. By understanding the basics of P/Invoke syntax, parameter passing, and considerations for interoperability, developers can effectively bridge the gap between managed and unmanaged environments, unlocking a wide range of capabilities for their applications.

I demonstrate a simple Hello World application using P/Invoke inter-op. First, I expose a C++ function in a dynamic link library (DLL). Then, I import the C++ function from the DLL into a C# console application and call it. Lastly, I demonstrate how you can automatically output your dll and console application to the same directory to speed up development.
C++ is powerful. Whether you need to manage resources more efficiently or you need to use a library that is only available in C++, there are times where you must use C++ in your C# application. P/Invoke is a powerful way to accomplish this. In this series, I will be demonstrating the power of P/Invoke inter-op and showing how you can implement P/Invokes into your own application.

I demonstrate how to marshal classes to and from C++ and C#. Although it is not possible to directly marshal classes, I demonstrate how to marshal a C++ class pointer to C#. The C# application then sends the pointer back to C++ to invokes methods on the class and send results back to the C# application. This allows the C# application to use the C++ class's functionality.

JAM20 - Native API Deep Dive: Get Flow with the Invocation Framework, Shadid Haque
The Invocation Framework in the BlackBerry® 10 platform is designed to allow one app to integrate with another, while also keeping the flow absolutely seamless and natural to the user. This session will cover the native APIs for the Invocation framework, demonstrating how you can invoke an app with your content and carry out an action while also including an embeddable view of another app inside yours. Then take it one step further by learning how to register your app as an invocable target. Join us to see why sharing content and performing tasks with another app has never been this easy or powerful.

Platform Invocation Services
Platform Invocation Services, commonly referred to as P/Invoke, is a feature of Common Language Infrastructure implementations, like Microsoft's Common Language Runtime, that enables managed code to call native code.
Architecture
Overview
Two variants of P/Invoke currently in use are:
Explicit
- This definition is the "Explicit" part
Implicit
- i.e. Adding/removing/re-ordering structures in a native header will be transparently supported so long as the structure member names did not also change.
