设置背景图片


#ifndef __BITMAPBKGND_H__
#define __BITMAPBKGND_H__
template <class T, UINT uBitmapID>
class CBitmapBkgnd : public CMessageMap
{
public:
	CBitmapBkgnd() { m_Bitmap.LoadBitmap(uBitmapID); }
	~CBitmapBkgnd() { m_Bitmap.DeleteObject(); }
	BEGIN_MSG_MAP(CPaintBkgnd)
		MESSAGE_HANDLER(WM_ERASEBKGND, OnEraseBkgnd)
	END_MSG_MAP()
 
	LRESULT OnEraseBkgnd(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
	{
		T*   pT = static_cast<T*>(this);
		HDC  hDC = (HDC) wParam;
		RECT rcClient;
		pT->GetClientRect ( &rcClient );
		
		BITMAP bm;
		m_Bitmap.GetBitmap(&bm);
		CDC memDC;
		memDC.CreateCompatibleDC(hDC);
		HBITMAP hOldBmp = memDC.SelectBitmap(m_Bitmap);
		StretchBlt(hDC,0,0,rcClient.right - rcClient.left,rcClient.bottom - rcClient.top,memDC,0,0,bm.bmWidth,bm.bmHeight,SRCCOPY);
		memDC.SelectBitmap(hOldBmp);
		memDC.DeleteDC();
		return 1;    // we painted the background
	}
protected:
	CBitmap m_Bitmap;
};
#endif //__BITMAPBKGND_H__
用法:
1.包含类的头文件;
2.让对话框类公有继承:public CBitmapBkgnd<CMainDlg, IDB_MAIN_BKGND>;
3.在消息映射之前:typedef CBitmapBkgnd<CMainDlg,IDB_MAIN_BKGND> CBmpBkgndBase;
4.在消息映射内:CHAIN_MSG_MAP(CBmpBkgndBase)

设置背景颜色以及字体颜色


#ifndef __CTRLCOLOR_H__
#define __CTRLCOLOR_H__
template <class T, COLORREF t_crTextColor = RGB(0, 0, 0), COLORREF t_crBkgnd = RGB(255,255,255)>
class CCtrlColor
{
public:
	CCtrlColor() { m_brBkgnd = CreateSolidBrush(t_crBkgnd);}
	~CCtrlColor() { DeleteObject(m_brBkgnd);}
 
	BEGIN_MSG_MAP(CCtrlColor)
		MESSAGE_HANDLER(WM_CTLCOLORDLG, OnCtlColor)
		MESSAGE_HANDLER(WM_CTLCOLORSTATIC, OnCtlColor)
	END_MSG_MAP()
	LRESULT OnCtlColor(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
	{
		HDC hDC = (HDC)wParam;
		HWND hWnd = (HWND)lParam;
		if(uMsg == WM_CTLCOLORDLG)
		{
			bHandled = TRUE;
			return (LRESULT)m_brBkgnd;
		}
		else if(uMsg == WM_CTLCOLORSTATIC)
		{	
			SetBkMode(hDC,TRANSPARENT);
			SetTextColor(hDC,t_crTextColor);
			
			bHandled = TRUE;
			return (LRESULT)m_brBkgnd;
		}
		else
			return 0;
	}
 
protected:
	HBRUSH m_brBkgnd;
};
#endif //__CTRLCOLOR_H__
