在一个CWinThread派生类创建窗口为什么总报警告错误

捕鲸叉 2013-07-17 04:03:57

如下窗口类.我在一个单独从CWinThread派生的线程类中创建该窗口(BOOL CRoutingWnd::Create()),但总是报警告错误.我的开发环境是WindowsXp/VC6. 请问是什么原因?

#pragma once



//内核线程消息路由窗口

class CRoutingWnd : public CWnd

{

	DECLARE_DYNAMIC(CRoutingWnd)



public:

	CRoutingWnd();

	virtual ~CRoutingWnd();

	BOOL Create();



protected:

	DECLARE_MESSAGE_MAP()

	//获取线程ID

	afx_msg LRESULT OnGetThreadID(WPARAM w, LPARAM l);	

	afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);

};



#include "stdafx.h"

#include "RoutingWnd.h"

#include "KernelThread.h"



#ifdef _DEBUG

#undef THIS_FILE

static char THIS_FILE[]=__FILE__;

#define new DEBUG_NEW

#endif

// CRoutingWnd

//InterpEngine







IMPLEMENT_DYNAMIC(CRoutingWnd, CWnd)



CRoutingWnd::CRoutingWnd()

{

}



CRoutingWnd::~CRoutingWnd()

{

}





BEGIN_MESSAGE_MAP(CRoutingWnd, CWnd)

	ON_WM_CREATE()

END_MESSAGE_MAP()



//获取线程ID

LRESULT CRoutingWnd::OnGetThreadID(WPARAM /*w*/, LPARAM /*l*/)

{

	return ::GetCurrentThreadId();

}





int CRoutingWnd::OnCreate(LPCREATESTRUCT lpCreateStruct) 

{

	if (CWnd::OnCreate(lpCreateStruct) == -1)

		return -1;

	

	TRACE("routing wnd created success!\n");	

	return 0;

}



BOOL CRoutingWnd::Create()

{

	CString str = AfxRegisterWndClass(0);

	if (!CreateEx(0, str, _T("Kernel Router"),

		WS_OVERLAPPED, 0, 0, 0, 0, NULL, NULL))

	{

		return FALSE;

	}



	return TRUE;

}
