ApplicationAPI Integration Guide

📂 Files needed

• ApplicationAPI.dll – The main dynamic library.
• ApplicationAPI.lib – Import library for linking.
• sdkdriver.dll - Communication with Drive app.
• ApplicationAPI.h – Header file with function declarations.

📌 Overview

This project demonstrates how to integrate and use ApplicationAPI.dll in a C++ application using Visual Studio 2022.

The project is structured as follows:

/InitApiDemo
│── /InitApiDemo        # Project directory
│    ├── /include       # Header files
│    │    ├── ApplicationAPI.h
│    │
│    ├── /lib           # Library files
│    │    ├── ApplicationAPI.dll
│    │    ├── ApplicationAPI.lib
│    │    ├── sdkdriver.lib
│    │
│    ├── main.cpp
│    ├── pch.cpp
│    ├── pch.h
│    │
│    ├── InitApiDemo.vcxproj  # Project file
│
│── InitApiDemo.sln     # Solution file
│── README.md           # This guide

🛠 Setup Instructions

1️⃣ Project Configuration

1. Open Visual Studio 2022 and load the project (.sln file) or create a new C++ console application.
2. Place library files (.dll, .lib, .h) into proper folders (lib, include).
3. Configure Include Directories:
   • Go to: Project Properties → C/C++ → General → Additional Include Directories
   • Add: $(ProjectDir)include
4. Configure Library Directories:
   • Go to: Project Properties → Linker → General → Additional Library Directories
   • Add: $(ProjectDir)lib
5. Link Against ApplicationAPI.lib:
   • Go to: Project Properties → Linker → Input → Additional Dependencies
   • Add: ApplicationAPI.lib

2️⃣ Post-Build Event (Copy DLL Automatically)

To ensure ApplicationAPI.dll and sdkdriver.dll are always placed next to the executable:

1. Go to: Project Properties → Build Events → Post-Build Event → Command Line
2. Add the following command:

   xcopy /Y "$(ProjectDir)lib\ApplicationAPI.dll" "$(OutDir)"
   xcopy /Y "$(ProjectDir)lib\sdkdriver.dll" "$(OutDir)"

   • This copies ApplicationAPI.dll and sdkdriver.dll to the output directory after building.

3️⃣ Build & Run

• Build the project (Ctrl + Shift + B).
• Run the executable (F5 or Ctrl + F5).

🔍 Troubleshooting

❌ ApplicationAPI.dll was not found

• Ensure ApplicationAPI.dll exists in the /lib folder.
• Run a clean build (Rebuild Solution).
• Manually copy ApplicationAPI.dll to the output folder.

❌ sdkdriver.dll was not found

• Ensure sdkdriver.dll exists in the /lib folder.
• Run a clean build (Rebuild Solution).
• Manually copy sdkdriver.dll to the output folder.

❌ Linker error: unresolved external symbol

• Verify that ApplicationAPI.lib is added to Additional Dependencies.
• Check that ApplicationAPI.h is included in the source file.
