Something like this:
<font face=tahoma><SPAN style="color:#00007F">Private</SPAN> <SPAN style="color:#00007F">Sub</SPAN> CheckBox1_Click()
<SPAN style="color:#00007F">If</SPAN> CheckBox1.Value = <SPAN style="color:#00007F">True</SPAN> <SPAN style="color:#00007F">Then</SPAN>
CheckBox2.Visible = <SPAN style="color:#00007F">False</SPAN>
Else: CheckBox2.Visible = <SPAN style="color:#00007F">True</SPAN>
<SPAN style="color:#00007F">End</SPAN> <SPAN style="color:#00007F">If</SPAN>
<SPAN style="color:#00007F">End</SPAN> <SPAN style="color:#00007F">Sub</SPAN></FONT>
