🎯 Features

• ✅ Manual PID search by process name (case-insensitive)
• 🔧 Dynamic path input for any DLL
• 💡 Unicode support (LoadLibraryW)
• 📦 Clean and portable C++ codebase (MSVC-ready)
• 📜 MIT License — free to use and modify
• 🧠 Good for learning injection & WinAPI basics

---

🧪 Installation

1. Clone the repository or download latest release
2. Open project in Visual Studio (or other C++ IDE)
3. Build as:
   • x64 if target process is 64-bit
   • x86 if target process is 32-bit
4. Make sure your DLL is compiled in the correct architecture to match the target

---

🚀 Usage

> Injector.exe

🧾 The injector will prompt you to:

1. Enter target process name (e.g. notepad.exe)
2. Enter full DLL path (absolute, e.g. C:\MyStuff\hook.dll)
3. If process and path are valid — injection will occur via CreateRemoteThread.

Upon success:
✅ “DLL Injected successfully!”

⚙️ Technical Overview

This injector uses the classic and well-documented LoadLibrary injection technique, implemented through:

• CreateToolhelp32Snapshot() → to iterate through system processes
• VirtualAllocEx() → to allocate memory in target process
• WriteProcessMemory() → to copy DLL path to remote memory
• CreateRemoteThread() → to launch LoadLibraryW in target process context

Architecture-aware:

• The injector must match the bitness (x86/x64) of the target process.
• Will fail silently or crash otherwise.

✏️ Unicode vs ANSI

• Uses LoadLibraryW for full compatibility with Unicode paths.
• If needed, you can easily switch to LoadLibraryA.

📝 Changelog

v1.0.0 — Initial stable release

• Added dynamic process lookup by name
• Switched to Unicode-based injection (LoadLibraryW)
• Improved input prompts and user experience
• Clean exit and error handling
• Modular and readable source

---

🛠 Troubleshooting

• ❌ "Injection failed" or no output?

  • Ensure your DLL exists and is compiled for correct architecture
  • Run injector as Administrator
  • Check antivirus or Windows Defender blocking CreateRemoteThread

• ❌ Target process not found?

  • Use full name including extension (e.g. chrome.exe)
  • Process might be running with elevated privileges — run injector as admin
