VC++可謂神通廣大,,如果學(xué)到家了,或者就掌握了那么一點(diǎn)MFC,,你也會(huì)感到它的方便快捷,,當(dāng)然最重要的是功能強(qiáng)大。不是嗎,,從最基本的應(yīng)用程序.EXE到動(dòng)態(tài)連接庫(kù)DLL,,再由風(fēng)靡網(wǎng)上的ActiveX控件到Internet Server API,當(dāng)然,還有數(shù)據(jù)庫(kù)應(yīng)用程序……瞧,,我都用它來(lái)做屏幕保護(hù)程序了,。一般的屏幕保護(hù)程序都是以SCR作為擴(kuò)展名,并且要放在c:\windows 目錄或 c:\windows\system 目錄下,,由Windows 98內(nèi)部程序調(diào)用(Windows NT 是在 c:\windows\system32 目錄下),。怎么調(diào)用?不用說(shuō)了,,這誰(shuí)不知道,。
好了,我們來(lái)作一個(gè)簡(jiǎn)單的,。選擇MFC AppWizard(exe),,Project Name 為MyScreensaver,[NEXT],,對(duì)話框,,再后面隨你了。打開(kāi)菜單Project,、Settings,,在Debug頁(yè)、Executable for debug session項(xiàng),,以及Link頁(yè)中Output file name項(xiàng)改為c:\windows\MyScreensaver.scr,,這樣,你可以調(diào)試完后,,直接在VC中運(yùn)行(Ctrl+F5),,便可看到結(jié)果。當(dāng)然,,這樣做的唯一缺點(diǎn)是你必須手動(dòng)清除Windows 目錄下的垃圾文件(當(dāng)然是在看到滿意結(jié)果后,;還有,你可借助SafeClean 這個(gè)小東東來(lái)幫你清除,,除非你的硬盤(pán)大的讓你感到無(wú)所謂……快快快回來(lái),,看我跑到那里去了)。接下來(lái)用Class Wizard生成CMyWnd類,,其基類為CWnd(在Base Class 中為generic CWnd),。這個(gè)類是我們所要重點(diǎn)研究的。創(chuàng)建滿屏窗口,、計(jì)時(shí)器,,隱藏鼠標(biāo),展示圖片,,響應(yīng)鍵盤(pán),、鼠標(biāo)等等,這家伙全包了。至于MyScreensaverDlg.h與MyScreensaverDlg.cpp文件我們暫時(shí)不管,。打開(kāi)MyScreensaver.cpp,,修改InitInstance()函數(shù):
BOOL CMyScreensaverApp::InitInstance()
{
AfxEnableControlContainer();
#ifdef _AFXDLL
Enable3dControls(); // Call this when using MFC in a shared DLL
#else
Enable3dControlsStatic(); // Call this when linking to MFC statically
#endif
CMyWnd* pWnd = new CMyWnd;
pWnd->Create();
m_pMainWnd = pWnd;
return TRUE;
}
當(dāng)然,再這之前得先 #include “MyWnd.h“ ,。后面要做的都在MyWnd.h 與 MyWnd.cpp 兩文件中了,。
下面給出CMyWnd 的說(shuō)明:
class CMyWnd : public CWnd
{
public:
CMyWnd();
static LPCSTR lpszClassName; //注冊(cè)類名
public:
BOOL Create();
public:
// ClassWizard generated virtual function overrides
//{{AFX_VIRTUAL(CMyWnd)
protected:
virtual void PostNcDestroy();
//}}AFX_VIRTUAL
public:
virtual ~CMyWnd();
protected:
CPoint m_prePoint; //檢測(cè)鼠標(biāo)移動(dòng)
void DrawBitmap(CDC& dc, int nI
