Implementation Guide

Now that we have our environment ready, let’s dive into the implementation steps for loading and converting a password-protected Word document.

Loading Password-Protected Documents

Overview

The first step involves securely loading your password-protected Word documents. This section will guide you through setting up the necessary configurations to handle such files effectively.

Step-by-Step Implementation

  1. Define Document Path Set the path to your document by replacing 'YOUR_DOCUMENT_DIRECTORY' with the actual directory:

    string documentPath = Path.Combine("YOUR_DOCUMENT_DIRECTORY", "protected_document.docx");

  2. Configure Load Options Specify the password for loading the document:

    var loadOptions = new WordProcessingLoadOptions
{
    Password = "yourPassword"
};

  3. Initialize Converter Use the Converter class to handle the conversion process:

    using (var converter = new Converter(documentPath, () => loadOptions))
{
    // Conversion logic will be added here
}

Converting to PDF

Overview

After loading your document, you’ll need to convert it into a desired format—in this case, PDF. This section details the conversion process.

Step-by-Step Implementation

  1. Set Up Convert Options Define how the file should be converted:

    var options = new PdfConvertOptions();

  2. Execute Conversion Perform the conversion and save the output:

    string outputPath = Path.Combine("YOUR_OUTPUT_DIRECTORY", "converted_document.pdf");

converter.Convert(outputPath, options);

Key Configuration Options

  • Password Handling: Ensure you securely manage passwords in your application.
  • Output Settings: Customize PDF settings like page range or watermarking as needed.

Troubleshooting Tips

  • Document Not Loading: Double-check the password and file path.
  • Conversion Errors: Verify that all necessary DLLs are included in your project references.
