Solution 2

If your form is a CFormView derived class, you may use CWnd::GetNextDlgTabItem() and CWnd::GetNextDlgGroupItem().

Solution 1

Why don't you use the EnumChildWindows[^] function?

[update]
Well, you have the documentation, after all.
Roughly speaking you call EnumChildWindows passing a the handle of ythedialog and a function pointer. Then Windows will call your function many times, each time passing the handle of a different dialog's child window.

ok i did the EnumChildWindow as belolw :


BOOL CALLBACK EnumChildProc( HWND hwnd, LPARAM lParam )
{
	int CtrlID = GetDlgCtrlID( hwnd );
	GetDlgItem(CtrlID);
	return TRUE;
}

and in the OnInitialupdate i added :


EnumChildWindows(GetSafeHwnd(),EnumChildProc, 0 );

But i think that int the pointed fuct i could not use teh GetDlgItem(CtrlID)->SetFont().

Confused !!!

You may send the WM_SETFONT message:
