Dialog Boxes - Radio Button mischief

I have a display setup dialog box with 3 different groups of radio buttons. One for full / Windowed mode select, one for bits per pixel select, and one for resolution select.
Now they are each in their respective static boxes. How do I make it where when I select my bpp one and then click resolution the black dot does not jump groups. I see the group tag in the resource editor but that kept messing up. Also, how do I initially set one of the radio buttons to marked in the WM_INITDIALOG message? Thanks for your time. If you don't read my sig I'm using VC++ 6.0 PRO

You should use group boxes to group the radio buttons, that should stop the black dot from jumping between groups. To set the radio button to checked you can use:

Code:

SendMessage(hWnd, BM_SETCHECK, BST_CHECKED, 0);

Here is some info on BM_SETCHECK

An application sends a BM_SETCHECK message to set the check state of a radio button or check box.

BM_SETCHECK
wParam = (WPARAM) fCheck; // check state
lParam = 0; // not used; must be zero


Parameters

fCheck

Value of wParam. Specifies the check state. This parameter can be one of the following values:

Value Meaning
BST_CHECKED Sets the button state to checked.
BST_INDETERMINATE Sets the button state to grayed, indicating an indeterminate state. Use this value only if the button has the BS_3STATE or BS_AUTO3STATE style.
BST_UNCHECKED Sets the button state to unchecked
Return Values

This message always returns zero.

Remarks

The BM_SETCHECK message has no effect on push buttons.
