This project is a C++ application that demonstrates how to download files using the Background Intelligent Transfer Service (BITS) via the Component Object Model (COM). The program allows downloading a file from a specified URL and saves it to a local path using background file transfer mechanisms that continue even if the application is closed, as managed by BITS.
- Background File Transfers: Uses BITS to download files in the background with low network impact.
- COM Interface Usage: Leverages COM (
IBackgroundCopyManager,IBackgroundCopyJob) to manage file download jobs. - Unicode Support: Supports wide-character (Unicode) file paths and URLs.
- Error Handling: Retrieves and prints detailed error descriptions if the download fails.
- Open the project in Visual Studio.
- Build the solution to compile the application.
After building the project, run the compiled executable from the command line using the following format:
BITSCOMClient.exe <source_url> <destination_path>
