The biggest problem with trying to make ActiveX controls shareware or trialware is knowing when the control is in the IDE. All of the methods require knowing which IDE you are in. Each IDE can have a different name, executable and class. This method allows you throw the NAG screen at the proper time regardless of the IDE. Use the property bag!
