1.? 新建一個MFC項目SDI或MDI。

2.? 新建或導入一個ID為IDB_SPLASH的位圖。

3.? 添加現有項SplashWnd.h和SplashWnd.cpp。

SplashWnd.h源代碼
#ifndef _SPLASH_HEADER_
#define _SPLASH_HEADER_

#pragma once
//#include "afxwin.h"

// CSplashWnd

class CSplashWnd : public CWnd
{
//DECLARE_DYNAMIC(CSplashWnd)

public:
CSplashWnd();
virtual ~CSplashWnd();
virtual void PostNcDestroy();

public:
CBitmap m_bitmap;

protected:
static BOOL c_bShowSplashWnd;
static CSplashWnd* c_pSplashWnd;

public:
static void EnableSplashScreen(BOOL bEnable = TRUE);
static void ShowSplashScreen(CWnd* pParentWnd = NULL);
static BOOL PreTranslateAppMessage(MSG* pMsg);

protected:
BOOL Create(CWnd* pParentWnd = NULL);
void HideSplashScreen();

afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
afx_msg void OnPaint();
afx_msg void OnTimer(UINT nIDEvent);

protected:
DECLARE_MESSAGE_MAP()
};

#endif
SplashWnd.cpp源代碼 // SplashWnd.cpp : 實現文件
//

#include "stdafx.h"
#include "resource.h"
#include "SplashWnd.h"


// CSplashWnd

//IMPLEMENT_DYNAMIC(CSplashWnd, CWnd)

BOOL CSplashWnd::c_bShowSplashWnd = FALSE;
CSplashWnd* CSplashWnd::c_pSplashWnd;

CSplashWnd::CSplashWnd()
{

}

CSplashWnd::~CSplashWnd()
{
// Clear the static window pointer.
ASSERT(c_pSplashWnd == this);
c_pSplashWnd = NULL;
}


BEGIN_MESSAGE_MAP(CSplashWnd, CWnd)
ON_WM_CREATE()
ON_WM_PAINT()
ON_WM_TIMER()
END_MESSAGE_MAP()


void CSplashWnd::EnableSplashScreen(BOOL bEnable /*= TRUE*/)
{
c_bShowSplashWnd = bEnable;
}

void CSplashWnd::ShowSplashScreen(CWnd* pParentWnd /*= NULL*/)
{
if (!c_bShowSplashWnd || c_pSplashWnd != NULL)
return;
// Allocate a new splash screen, and create the window.
c_pSplashWnd = new CSplashWnd;
if (!c_pSplashWnd->Create(pParentWnd))
delete c_pSplashWnd;
else
c_pSplashWnd->UpdateWindow();
}

BOOL CSplashWnd::PreTranslateAppMessage(MSG* pMsg)
{
if (c_pSplashWnd == NULL)
return FALSE;

// If we get a keyboard or mouse message, hide the splash screen.
if (pMsg->message == WM_KEYDOWN ||
pMsg->message == WM_SYSKEYDOWN ||
pMsg->message == WM_LBUTTONDOWN ||
pMsg->message == WM_RBUTTONDOWN ||
pMsg->message == WM_MBUTTONDOWN ||
pMsg->message == WM_NCLBUTTONDOWN ||
pMsg->message == WM_NCRBUTTONDOWN ||
pMsg->message == WM_NCMBUTTONDOWN)
{
c_pSplashWnd->HideSplashScreen();
return TRUE; // message handled here
}

return FALSE; // message not handled
}

BOOL CSplashWnd::Create(CWnd* pParentWnd /*= NULL*/)
{
if (!m_bitmap.LoadBitmap(IDB_SPLASH))
return FALSE;

BITMAP bm;
m_bitmap.GetBitmap(&bm);

return CreateEx(0,
AfxRegisterWndClass(0, AfxGetApp()->LoadStandardCursor(IDC_ARROW)),
NULL, WS_POPUP | WS_VISIBLE, 0, 0, bm.bmWidth, bm.bmHeight, pParentWnd->GetSafeHwnd(), NULL);
}


void CSplashWnd::HideSplashScreen()
{
// Destroy the window, and update the mainframe.
DestroyWindow();
AfxGetMainWnd()->UpdateWindow();
}

void CSplashWnd::PostNcDestroy()
{
// Free the C++ class.
delete this;
}

int CSplashWnd::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CWnd::OnCreate(lpCreateStruct) == -1)
return -1;

// Center the window.
CenterWindow();

// Set a timer to destroy the splash screen.
SetTimer(1, 1000, NULL);

return 0;
}

void CSplashWnd::OnPaint()
{
CPaintDC dc(this);

CDC dcImage;
if (!dcImage.CreateCompatibleDC(&dc))
return;

BITMAP bm;
m_bitmap.GetBitmap(&bm);

// Paint the image.
CBitmap* pOldBitmap = dcImage.SelectObject(&m_bitmap);
dc.BitBlt(0, 0, bm.bmWidth, bm.bmHeight, &dcImage, 0, 0, SRCCOPY);
dcImage.SelectObject(pOldBitmap);
}

void CSplashWnd::OnTimer(UINT nIDEvent)
{
// Destroy the splash screen window.
HideSplashScreen();
}

4.? 在App主程序實現代碼中把上面的頭文件包含進去，并在InitInstance函數中添加下面一段代碼。?

{
　　CCommandLineInfo cmdInfo;
　　ParseCommandLine(cmdInfo);
　　CSplashWnd::EnableSplashScreen(cmdInfo.m_bShowSplash);
}

5.? 最后，在主框架窗口實現代碼中包含Splash頭文件，在OnCreate函數return前調用CSplashWnd類的ShowSplashScreen函數即可。?

//顯示Splash窗口
CSplashWnd::ShowSplashScreen(this);

?
