继承CWinthread，显示动态的启动进度条

因为软件初始化硬件比较费时，不想让用户看到界面没有反应的样子，可以做了一个进度条，像WINDOWS启动时的进度条一样，来回显示

SplashThread.h

#include "StdAfx.h"
#include "SplashScreen.h"

CSplashScreen::CSplashScreen()
{
	m_pSplashThread=NULL;
}

CSplashScreen::~CSplashScreen(void)
{
	if ( m_pSplashThread )
	{
		Close();
	}
}


/// 显示窗口
bool CSplashScreen::ShowWindow(CString szMessage, UINT nTime/* =200 */)
{
	if ( !m_pSplashThread )
	{
		m_pSplashThread= new CSplashThread();
		m_pSplashThread->m_szMessage= szMessage;
		m_pSplashThread->m_nTime= nTime;
		m_pSplashThread->CreateThread();
	}
	return true;
}

/// 关闭窗口
void CSplashScreen::Close()
{
	m_pSplashThread->PostThreadMessage( WM_QUITSPLASHSCREEN, NULL, NULL);
	m_pSplashThread=NULL;
}

SplashThread.cpp

#include "StdAfx.h"
#include "SplashThread.h"

IMPLEMENT_DYNCREATE(CSplashThread, CWinThread)

CSplashThread::CSplashThread(void)
{
	m_szMessage=_T("请稍候,正在启动...");
	m_nTime= 200;
	m_pProgress=NULL;

	m_bAutoDelete=TRUE;
}

CSplashThread::~CSplashThread(void)
{
}


BEGIN_MESSAGE_MAP(CSplashThread, CWinThread)
	ON_THREAD_MESSAGE(WM_QUITSPLASHSCREEN, OnQuit)
END_MESSAGE_MAP()


BOOL CSplashThread::InitInstance()
{
	m_pProgress= new COPWILLProgress();
        //一定要加下面的这行，否则如果主界面线程忙碌的话，进度条会没有反应	
        m_pMainWnd=m_pProgress;
	m_pProgress->Create(m_szMessage, m_nTime);
	m_pProgress->ShowWindow(SW_SHOW);
	return TRUE;
}

BOOL CSplashThread::ExitInstance()
{
	if ( m_pProgress )
	{
		m_pProgress->DestroyWindow();
		delete m_pProgress;
	}
	return TRUE;
}

/// 退出启动条
void CSplashThread::OnQuit(WPARAM wParam,LPARAM lParam)
{
	PostQuitMessage(0);
}
