#12: How can I check a checkbox without triggering of OnClick event?

Sometimes it's necessary to change a state of TCheckBox component, but without operation of OnClick event. This task can be solved so:

{set a checked}
yourCheckBox.Perform(BM_SETCHECK, 1, 0);
{set a unchecked}
yourCheckBox.Perform(BM_SETCHECK, 0, 0);
or else in one procedure
procedure ChangeChecked(ACheckBox: TCheckBox; AState: Boolean);
begin
  ACheckBox.Perform(BM_SETCHECK, Ord(AState), 0);
end;
For example, if you will call the ChangeChecked(myCheckBox, True), then will be myCheckBox.Checked = True.
