添加启动类

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_PAINT
Sleep(2500);
wndSplash.DestroyWindow();//销毁初始画面窗口
