The GetDlgItem function retrieves the handle of a control in the specified dialog box.

HWND GetDlgItem(
HWND hDlg, // handle of dialog box
int nIDDlgItem // identifier of control
);

Notice the above text from MSDN.

I tried using null for the 2nd variable

Don't use NULL for the 2nd variable:
(1) Because the HWND structure was supposed to be the first variable, hence your original error:

error C2664: 'GetDlgItem' : cannot convert parameter 1 from 'int' to 'struct HWND__ *'

(2) Because the HWND parameter in GetDlgItem is supposed to be the handle of the dialog that this dialog item is on. Try possibly, this, the word "this" referring to "the current dialog".

The simpler, though perhaps more unpopular/messier way would be to use UpdateData(), but not UpdateData(FALSE). The check boxes usually function pretty cool by themselves (i.e. checking an unchecking themselves when you click on them), but you're trying to control a partner check box. So, try something like:

<br />
void OnCheck20(void){<br />
  UpdateData(TRUE); //This gets the current state of all the dialog items, so you won't be overwriting anything.<br />
<br />
  if(m_Check20 == true){<br />
    m_Check21 = false;<br />
    UpdateData(FALSE);<br />
  }<br />
  else if(m_Check20 == false){ // The user just hit the button from true to false.<br />
    // Do nothing, if you want the user to be able to unselect these options.<br />
  }<br />
}<br />


Write a similar function for the other check box. You just gotta use the UpdateData(TRUE) so you don't change all the other controls to their last updated state.
