Z-Order of DDV Message-Box with Modeless Dlg

G'day!
One of the fields in this dialog is range-checked. The "Please enter a
number between 1 and 100" message-box is small enough to be buried
behind the dialog, should the User have dragged it into centre-frame.
The User now has no visible clues as to why things have apparently
hung.
Any suggestions as to how to force the message-box to the top?

Instead of a message box u can load a modal dialog which looks like
the message box and u can call SetActiveWindow() or SetFocus(SW_SHOW)
to show the dialog at the top of all windows.
I am talking of dialog box instead of message box bcos i don't have any
clue as to how to get the hwnd of a MessageBox().
I am sure whether there are any other solutions also or not but this
seems to be a quick and dirty solution.
Bye

1. This message box is displayed by MFC core, not by programmer code.
2. It is called when you call (or MFC call for you) UpdateData(). You can use Windows hook (WH_CBT) to look for dialog creation and move it accordingly.

Thanks, Hemanta,
But the message-box is indirectly generated through
void CModelessDlg::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
//{{AFX_DATA_MAP(CSheetDim)
DDX_Text(pDX, IDC_A_NUMBER, m_nThing);
DDV_MinMaxFloat(pDX, m_nThing, 1.0, 100.0);
While the z-order is always fine for a modal dialog (topmost), a modeless dialog seems to take precedence, and the message-box evaluated as "unviewable".
Looks like I'll have to do my own range-checks, and dump my own "Please fix!" message in the actual dialog.

Thanks, Dmitry,
But I only have DDV range-check to consider. Courtesy of Mike B.'s "Nabbed Edit" in Chapter 7 of "The Revolutionary Guide...", I've killed off the "Enter a number, you clod!" box. UpdateData() will always operate cleanly. Looking at the use of WH_CBT in the source makes me feel that beeping and dumping my own message into a CStatic is an easier way to go.
