Problem with static methods

[Chris Clement]

I didn't write this code so I'm not sure what is going on with this error.
checkedListBox1 is a public object. Why does the error say that it is
expecting a 'class' in a for loop? Is it because the method is static?
Here is the error and the code:

C:\...\Form1.cs (1130): 'APP.mainForm.c heckedListBox1' denotes a 'field'
where a 'class' was expected
public static void MenuItem_Click( object sender, System.EventArg s e)
{
for(int i = 0; i<checkedListBo x1.Items.Count; i++)//<<<<line 1130
{
checkedListBox1 .SetItemChecked (i,false);
}
}

Also getting an error saying: C:\...\newPromp t.cs(172): An object reference
is required for the nonstatic field, method, or property
'APP.mainForm.M enuItem'
private void button1_Click(o bject sender, System.EventArg s e)
{
for(int o = mainForm.histor yMenuItem.MenuI tems.Count-1; o>=0;o--)
mainForm.histor yMenuItem.MenuI tems.RemoveAt(o );

}

Help is appreciated.

Since your function is declared static, it can be called
without instantiation of your form class wich contains
the checkbox. Therefore your static function has know
way of knowing a checkbox exists. Why are you using a
static function here anyway?

I hope that makes sense.
