Example 2 is very handy for checking if a given control is controlNull without using negation.
Here is a practical example of that:
however, keep in mind that most controls have[ controlNull ] call { if( ctrlIDC( _this select 0 ) > -1 ) then { systemChat "the control exists!" } }idc = -1;by default. But that is easy to change :)
The method shown above works great for functions where a control or controlNull could get passed into.
If the function should only do something if the control exists, then that method is a great way to handle that while avoiding negation.
