Implementation Guide

Let’s break down the implementation into distinct sections based on functionality.

Loading a Word Processing Document

Overview

Loading documents is the first step in editing them. This feature allows you to open a Word document, even if it’s password-protected.

Step-by-step Implementation

Set Up Load Options:

string inputFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.docx";
using (FileStream fs = File.OpenRead(inputFilePath))
{
    // Create load options for the document.
    var loadOptions = new WordProcessingLoadOptions();

    // If needed, specify a password to open protected documents.
    loadOptions.Password = "some_password_to_open_a_document";

    // Load the document into an Editor instance.
    using (Editor editor = new Editor(fs, loadOptions))
    {
        // Document loaded successfully
    }
}

Parameters: inputFilePath specifies your file location. The password option is crucial for accessing secured documents.

Troubleshooting:
- Ensure the document path and password (if applicable) are correct.
- Check file permissions to avoid access errors.

Editing a Word Processing Document

Overview

Editing involves modifying the content of loaded documents, which can be necessary for customizing templates or automating data updates.

Step-by-step Implementation

Prepare Edit Options:

using (Editor editor = new Editor(fs, loadOptions))
{
    var editOptions = new WordProcessingEditOptions()
    {
        FontExtraction = FontExtractionOptions.ExtractEmbeddedWithoutSystem,
        EnableLanguageInformation = true,
        EnablePagination = true
    };

    // Create an EditableDocument instance with the editing options.
    using (EditableDocument beforeEdit = editor.Edit(editOptions))
    {
        string originalContent = beforeEdit.GetContent();

        // Modify content as needed
        string editedContent = originalContent.Replace("document", "edited document");

        // Create a new EditableDocument instance with modified content
        using (EditableDocument afterEdit = EditableDocument.FromMarkup(editedContent, beforeEdit.AllResources))
        {
            // Document editing completed successfully
        }
    }
}

Key Options: Font extraction and pagination are configured for optimal document handling.

Troubleshooting:
- Verify the correctness of content replacement logic.
- Check that all resources (images, fonts) are correctly managed post-editing.

Saving an Edited Word Processing Document

Overview

After editing, you need to save your changes back into a Word file format with specified options like password protection or read-only settings.

Step-by-step Implementation

Configure Save Options:

string inputFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.docx";
var docmFormat = WordProcessingFormats.Docm;
var saveOptions = new WordProcessingSaveOptions(docmFormat)
{
    Password = "password",
    EnablePagination = true,
    Locale = CultureInfo.GetCultureInfo("en-US"),
    OptimizeMemoryUsage = true,
    Protection = new WordProcessingProtection(WordProcessingProtectionType.ReadOnly, "write_password")
};

string outputFilename = Path.GetFileNameWithoutExtension(inputFilePath) + "." + docmFormat.Extension;
string outputPath = Path.Combine("YOUR_OUTPUT_DIRECTORY", outputFilename);

using (FileStream outputStream = File.Create(outputPath))
{
    // Assuming the document is already loaded and edited
    EditableDocument afterEdit = null; // Replace with actual edited content

    // Save the edited document
    editor.Save(afterEdit, outputStream, saveOptions);
}

Parameters: Adjust saveOptions to fit specific requirements like encryption or format type.

Troubleshooting:
- Ensure output paths are correctly defined.
- Validate that all save options align with your document’s security needs.

Practical Applications
