Issue
Historically, picking a date in Citect has always been achieved using the Microsoft Date and Time Picker Control 6.0 Active X object that comes along with most Windows installation. However, as time progresses on, this Active X is no longer as popular as it used to be. Often, projects which uses the Active X, which are migrated from older systems into a new Windows 10 or above environment will fail on Compile. And installing the Active X is often difficult because it may require installing a whole bunch of un-related software just to get it. And many times, even with the Active X already in the environment, the project still does not Compile, or fail to run properly.
Resolution
There is an alternative to using Date and Time Picker Control 6.0 Active X and this article is to introduce how to use the Calendar Genie in lib_controls Library to do that. It will involve the implementation of a Callback Function, and this article explains how this is to be created and used.
