MFC：控件尺寸随窗口变化

.h中：

	POINT Old;
	void resize();

.cpp的OnInitDialog()：

	CRect rect;
	GetClientRect(&rect);//取客户区大小
	Old.x = rect.right - rect.left;
	Old.y = rect.bottom - rect.top;

.cpp:

void CDefectBugDlg::resize()
{
	float fsp[2];
	POINT Newp;																		//获取现在对话框的大小
	CRect recta;
	GetClientRect(&recta);															//取客户区大小  
	Newp.x = recta.right - recta.left;	
	Newp.y = recta.bottom - recta.top;
	fsp[0] = (float)Newp.x / Old.x;
	fsp[1] = (float)Newp.y / Old.y;
	CRect Rect;
	int woc;
	CPoint OldTLPoint, TLPoint;													//左上角
	CPoint OldBRPoint, BRPoint;													//右下角
	HWND  hwndChild = ::GetWindow(m_hWnd, GW_CHILD);		//列出所有控件  
	while (hwndChild)
	{
		woc = ::GetDlgCtrlID(hwndChild);										//取得ID
		GetDlgItem(woc)->GetWindowRect(Rect);
		ScreenToClient(Rect);
		OldTLPoint = Rect.TopLeft();
		TLPoint.x = long(OldTLPoint.x*fsp[0]);
		TLPoint.y = long(OldTLPoint.y*fsp[1]);
		OldBRPoint = Rect.BottomRight();
		BRPoint.x = long(OldBRPoint.x *fsp[0]);
		BRPoint.y = long(OldBRPoint.y *fsp[1]);
		Rect.SetRect(TLPoint, BRPoint);
		GetDlgItem(woc)->MoveWindow(Rect, TRUE);
		hwndChild = ::GetWindow(hwndChild, GW_HWNDNEXT);
	}
	Old = Newp;
}
