本文讨论了MFC中Radio Button的使用及其Tab Order设置的问题。当Radio Button组内出现非Radio Button控件时，会触发警告信息。正确的设置方法是确保第一个Radio Button具有Group属性，并在组的最后一个Radio Button之后的控件也设置Group属性。

假定有两组Radio-button, 第一组有两个button Tab-Order分别为 6 和 7 （6号的Group 属性打勾）。另一组的两个button Tab-Order分别为 10和 11（１０号的Group 属性打勾）。 Tab-Order号为12的控件是一个EditBox, 将此EditBox的Group属性打勾。就可消除skipping non-radio button in group错误。

Does anybody know what this warning message means? "Warning: skipping
>non-radio button in group" and how can I correct the problem?

MFC assumes that a group of radio buttons are in consecutive tab order. In
certain circumstances you might not want this, for instance if an edit field
next to a radio button gives extra info about just that one choice. If you are
happy with how your group of radio buttons responds to the tab key, then this
is not really a problem.

Probably you have incorrectly assigned tab orders in your dialog. Check out
the "Layout/Tab Order" command in VC dialog editor.

A Radio button group is created by setting the first radio button in the
group with the "group" attribute. Then the group is supposed to consist of
all subsequent items in the tab order until the next item that has the group
attribute set. Evidently, you have not set the group attribute for the control
immediately following the last radio button in the tab order.

Use the editor to look at the Tab Order of the controls. Make sure the first
radio has the Group setting and go in order until the next thing that has
Group (lot of folks use a group box around the related radio buttons and set
it to Group and give it tab order after the last radio in the grouping). Make
sure all the controls between the two Group marks are all radios (and not some
other kind of control).

This warning comes becos of WS_GROUP style not set properly for Dialogs which
has radio buttons and other buttons in a SAME GROUP. Solution: Just set the
WS_GROUP style for all controls other than Radio buttons(Which you want to
group). Here is snippet of code which causes this warning.

File : ...\VC\mfc\src\DLGDATA.CPP

void AFXAPI DDX_Radio(CDataExchange* pDX, int nIDC, int& value)
    // must be first in a group of auto radio buttons
{

    // walk all children in GROUP to check the states
    int iButton = 0;
    do
    {

        //Check whether the button in the group box is radio button
if not it gives the warning
        if (::SendMessage(hWndCtrl, WM_GETDLGCODE, 0, 0L) &
DLGC_RADIOBUTTON)
        {
            // control in group is a radio button
            ........................
            Check the state of the radio button
        }
        else
        {
            TRACE0("Warning: skipping non-radio button in group.\n");
        }
        hWndCtrl = ::GetWindow(hWndCtrl, GW_HWNDNEXT);

    } while (hWndCtrl != NULL &&
        !(GetWindowLong(hWndCtrl, GWL_STYLE) & WS_GROUP));
}

The problem is that the next control in the tab order following the last radio
button of your group must have the WS_GROUP flag set.

ex:
Control        Group Flag On
Static Text          Yes
Radio Button1        Yes
Radio Button2        No
Radio Button3        No
Button               Yes

In the previous list, if the last button did not have the group flag set you
would get the TRACE warning while running.

In the Resource Editor, you need to set the tab order for the Radio buttons -
they must be sequential. The first button must have the Group property set,
and the first item following the last button must also have the Group property
set
