添加.h和cpp

#pragma once#include "afxwin.h"class mySplash :    public CWnd{    DECLARE_DYNAMIC(mySplash)protected:    DECLARE_MESSAGE_MAP()public:    CBitmap m_bitmap;    void Create(UINT nBitmapID);    afx_msg void OnPaint();    afx_msg void OnTimer(UINT_PTR nIDEvent);public:    mySplash(void);    ~mySplash(void);};

#include "stdafx.h"#include "mySplash.h"IMPLEMENT_DYNAMIC(mySplash, CWnd)mySplash::mySplash(){}mySplash::~mySplash(){}BEGIN_MESSAGE_MAP(mySplash, CWnd)    ON_WM_PAINT()    ON_WM_TIMER()END_MESSAGE_MAP()void mySplash::Create(UINT nBitmapID){    m_bitmap.LoadBitmap(nBitmapID);    BITMAP bitmap;    m_bitmap.GetBitmap(&bitmap);    CreateEx(0,AfxRegisterWndClass(0, AfxGetApp()->LoadStandardCursor(IDC_ARROW)),NULL, WS_POPUP | WS_VISIBLE, 0, 0, bitmap.bmWidth, bitmap.bmHeight, NULL, NULL);}void mySplash::OnPaint(){    CPaintDC dc(this);     BITMAP bitmap;    m_bitmap.GetBitmap(&bitmap);    CDC dcComp;    dcComp.CreateCompatibleDC(&dc);    dcComp.SelectObject(&m_bitmap);    dc.BitBlt(0, 0, bitmap.bmWidth, bitmap.bmHeight, &dcComp, 0, 0, SRCCOPY);}void mySplash::OnTimer(UINT_PTR nIDEvent){    DestroyWindow(); //销毁初始画面窗口}

 

而后在initdialog中添加

mySplash wndSplash; //创建启动窗口类的实例wndSplash.Create(IDB_BITMAP1);wndSplash.CenterWindow();wndSplash.UpdateWindow(); //send WM_PAINTSleep(2500);wndSplash.DestroyWindow();//销毁初始画面窗口
