These will cause error:
- DateTimePicker.value = DateTime.Now().ToString("yyyy-MM-dd dddd hh:mm:ss tt")
- DateTimePicker.value = Format(Now, "yyyy-MM-dd dddd hh:mm:ss tt")
if assign value to any components(comboBox.selectedIndex, DateTimePicker.value) within constructor New() body, after form those assigned value don't work as expected.
fixed by: assign value within form_load body.
