Using a controls property directly for TRUE or FALSE

Imaging you are writing some code which detects if a text box is visible or not on the form. If it is visible, then you want to make it not visible. Likewise, if it is not visible then you want to make it visible.

You might write some code like this:

However, you can make the code simpler because the Visible property of the button only returns TRUE or FALSE, which you can use directly as follows:

We can even go further because what we actually want to do is set the visible property to the opposite of what it currently is. Using the “NOT” command can do this for use (ie it turns TRUE into FALSE and vice versa).
