Implementation Guide

Now that you’ve set up your project, let’s dive into implementing a metered license feature. We’ll break it down step-by-step for clarity.

Setting Metered License

This feature allows you to control and monitor the usage of GroupDocs Watermark by setting a metered key.

Overview

The SetMeteredLicense method integrates your application with GroupDocs’ licensing server, enabling you to track usage based on the keys provided. This is crucial for ensuring compliance in enterprise environments or when distributing software with usage restrictions.

Step 1: Define Your License Keys

Start by defining your public and private license keys. These are unique to your account and application:

string publicKey = "*****"; 
string privateKey = "*****";
Step 2: Create an Instance of the Metered Class

Initialize the Metered class, which handles interactions with GroupDocs’ licensing server:

Metered metered = new Metered();
Step 3: Set the Metered Key

Use your license keys to set up the metered configuration. This step links your application’s usage to the keys provided by GroupDocs.

metered.SetMeteredKey(publicKey, privateKey);

Explanation: The SetMeteredKey method configures your application to track its watermarking activities according to the specified license limits.

Troubleshooting Tips

  • Invalid Keys: Ensure that your public and private keys are correctly copied from GroupDocs.
  • Network Issues: Verify network connectivity if you encounter errors related to server communication.
  • Version Compatibility: Check that your version of GroupDocs Watermark is compatible with the .NET framework in use.

Practical Applications

Understanding how metered licensing can be applied in real-world scenarios will help you leverage its full potential:

  1. Enterprise Document Management: Control usage across multiple departments or users within an organization.
  2. Software Distribution: Set limits on how many times your software can apply watermarks before requiring renewal.
  3. Trial Version Restrictions: Offer trial versions with limited functionality to encourage upgrades.

Performance Considerations

To ensure optimal performance while using GroupDocs Watermark, consider the following:

  • Resource Usage Guidelines: Monitor memory and CPU usage when processing large batches of documents.
  • Best Practices for .NET Memory Management:
    • Dispose of objects properly after use to free up resources.
