Dialog question, radio to enable control

[fdy]

Hi,
I'm trying to use radio buttons to enable/disable another control in a dialog box as soon as it is pressed. I know to use

GetDlgItem(IDC_SLIDER_...)->EnableWindow(false);

but don't know where to call it. Tried calling it in my dialog class in DoDataExchange function ( if(pDX->m_bSaveAndValidate) ... )
but that doesn't work.
do u see my problem? What happens when a dialog selection is changed.

Appreciate any help...

Figured it out. Called the message handler for BN_CLICKED.

Also have a look at WM_INITDIALOG (OnInitDialog) or WM_CREATE if you want to set up the dialog/window before it is shown.
