[dba-VB] CheckBox: Checked and CheckState

We use the CheckStateChanged event and test the Checked value of the
checkbox to determine interaction with other controls.  No focus
shifting required.

Hi all

Maybe the answer is here. At least this is comprehendible and not rocket
science:

The ThreeState property determines whether the control supports two or
three states. 

Use the Checked property to get or set the value of a two-state CheckBox
control and use the CheckState property to get or set the value of a
three-state CheckBox control.

Note: 
If the ThreeState property is set to true, the Checked property will
return true for either a checked or indeterminate state.

Any comments?

Hi all

What is the difference between these two events for a bound CheckBox?

Whatever I try, first event CheckedChanged is fired, then
CheckStateChanged - no matter if I browse the source it is bound to or
if I click or keypress the CheckBox itself (has focus).
