Understanding the Need for Document Templates

Before delving into the technical aspects, let's understand the significance of document templates. A document-based template serves as a reference, a blueprint, or a skeleton for creating a new document with predefined structure, formatting, and placeholders for dynamic content. Templates offer several advantages, including:

1. Consistency: Templates ensure that documents adhere to consistent layouts, stylings, and branding across various instances.
2. Efficiency: Providing predefined structures, and templates expedite the document creation process, minimizing manual effort and potential errors.
3. Customization: Templates can be customized to include placeholders for dynamic data, allowing documents to be personalized based on specific requirements.

' Define the output path for the populated document
Dim outputFilePath As String = "customer_info.docx"

' Save the populated document to the specified file path
doc.SaveAs(outputFilePath)

// Event handler for button click to generate the document
private void GenerateButton_Click(object sender, EventArgs e)
{
    CreateDocumentFromTemplate();
}

// Event handler for button click to generate the document
private void GenerateButton_Click(object sender, EventArgs e)
