(C# UWP/WinRT) Unlocks the Chilkat Crypt2 Class

Demonstrates how to unlock the Chilkat Crypt2 functionality. The UnlockComponent method should be called once at the beginning of the program. Once unlocked, all subsequent objects are created in the unlocked state. There is no need to call UnlockComponent for every instance of a Chilkat object.

The object that called UnlockComponent may be discarded (deleted, deallocated, etc.). It does not need to remain in existence for subsequent objects to be already unlocked when created.

Also, the LastErrorText method can be examined to verify that a purchased unlock code was indeed recognized.

Chilkat for the Universal Windows Platform (UWP)

Chilkat.Crypt2 crypt = new Chilkat.Crypt2();

//  If a license is purchased, replace "Anything for 30-day trial" with the purchased unlock code.
bool success = crypt.UnlockComponent("Anything for 30-day trial");
if (success != true) {
    Debug.WriteLine(crypt.LastErrorText);
    Debug.WriteLine("unlock failed.");
    return;
}

//  If debugging, you can examine the LastErrorText even when a method is successful.
//  This allows one to see what transpired within the method call, especially
//  if the VerboseLogging property is turned on.
//  In this case, a programmer can examine the LastErrorText to see if success
//  was w/ a purchased (and recognized) unlock code, or if it was successful in trial mode.

Debug.WriteLine(crypt.LastErrorText);
Debug.WriteLine("unlock successful.");
