Global Unlock

Demonstrates how to unlock the Chilkat API with a global (Bundle) purchased unlock code, or with a 30-day trial unlock code. Java

import com.chilkatsoft.*;

public class ChilkatExample {

  static {
    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {
      System.err.println("Native code library failed to load.\n" + e);
      System.exit(1);
    }
  }

  public static void main(String argv[])
  {
    boolean success = false;

    // The Chilkat API can be unlocked for a fully-functional 30-day trial by passing any
    // string to the UnlockBundle method.  A program can unlock once at the start. Once unlocked,
    // all subsequently instantiated objects are created in the unlocked state. 
    // 
    // <b>After licensing Chilkat, replace the "Anything for 30-day trial" with the purchased unlock code.</b>
    // To verify the purchased unlock code was recognized, examine the contents of the LastErrorText
    // property after unlocking.  For example:
    CkGlobal glob = new CkGlobal();
    success = glob.UnlockBundle("Anything for 30-day trial");
    if (success != true) {
        System.out.println(glob.lastErrorText());
        return;
        }

    int status = glob.get_UnlockStatus();
    if (status == 2) {
        System.out.println("Unlocked using purchased unlock code.");
        }
    else {
        System.out.println("Unlocked in trial mode.");
        }

    // The LastErrorText can be examined in the success case to see if it was unlocked in
    // trial more, or with a purchased unlock code.
    System.out.println(glob.lastErrorText());
  }
