Using Visual Studio 2003.

In a dialog (CDialog), I want to initially disable the OK button until the
user selects an item in a list box on that dialog. When an item is
selected I
want to enable the OK button and give it focus (so that the button has a
bold
outline showing that it has focus).

What I get is: The OK button is initially disabled (greyed out). There
is no
initial selection in the list box. When a selection is made in the list
box,
the OK button is enabled but it does not visually seem to have focus. When
a
*second* selection is made in the list box, the OK button is given focus.

I do the following:

dialog data (set up using "Add Variable"):

   CListBox cListBox;
   CButton cOK;

in OnInitDialog():

   cOK.EnableWindow(FALSE):

in OnLbnSelchangecListBox() -- when the list box selection changes:

   cOK.EnableWindow(TRUE);
   cOK.SetFocus();

What am I doing wrong?

I don't know, but FYI if the OK button is the default button, you don't need
to set the focus to it in order for it to click when you press the Enter
key.
