Two ways you can do it...

1. If they are the only checkboxes on the form(or panel, etc):

For each ctl as Control in Me.Controls
    If TypeOf ctl is Checkbox then CType(ctl, Checkbox).Checked = False
Next ctl

2. If there are other controls you don't want to mess with, you'll need to just specify each checkbox by name, such as:

CheckBox1.Checked=False
CheckBox2.Checked=False
...
