SimpleDLLInjector

Inject custom DLLs into Windows processes with a minimal, Qt-based GUI. The application lists all running processes and their target architecture (x64 or x86) and allows you to inject .dll from one GUI.

---

Features

• Supports x64 and x86 target applications.
• Very simple Qt GUI frontend.
• Headless support for using without Qt.
• Built with C++17 and CMake.
• Automatically deploys with windeployqt for easy distribution.

Build Instructions

Prerequisites

• CMake ≥ 3.5
• Qt 6.x (with Widgets module)
• C++17 compatible compiler (e.g., MSVC, Clang)
• Windows OS

Build Steps

1. Clone the repository:

   git clone https://github.com/yourusername/SimpleDLLInjector.git
   cd SimpleDLLInjector

Configure and build:

mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
cmake --build . --config Release

Configure and build a headless x86 injector under \backend\app to inject into x86 applications and place it into the same folder as GUI executable. You can skip this step if you don't aim for x86 apps.

Output: The final executable and necessary Qt dependencies will be placed in the bin/ directory.
