debug assertion failed MFC

场景：MFC Debug Assertion Failed!解决办法

MFC Debug Assertion Failed!
出错部分代码如下：

bool LinkLicenseServer()

{

	if(!AfxSocketInit())

	{

		AfxMessageBox(L"Error 201:Socket Initial Failed！");

		return false;

	}

	CClientSocket *clientSocket;

	clientSocket = new CClientSocket();

	clientSocket->AsyncSelect(FD_READ|FD_WRITE|FD_OOB); //在此弹出图片1和2


	CString m_strServer=LicenseIP;

	long licport = _wtol(LicensePort);

	if(!clientSocket->Create())  //在此第三张图片弹出两遍

	{

		::AfxMessageBox(L"Error 202:Connect to the License server failed！");

		return false;

	}


	if(!clientSocket.Connect(m_strServer,licport))

	{

		::AfxMessageBox(L"Error 203:Connect to the License server failed！");

		return false;

	}

......

图1图2出错相关代码：

BOOL CAsyncSocket::AsyncSelect(long lEvent)

{

	ASSERT(m_hSocket != INVALID_SOCKET);//第386行


	_AFX_SOCK_THREAD_STATE* pState = _afxSockThreadState;

	ASSERT(pState->m_hSocketWindow != NULL);//第389行


	return WSAAsyncSelect(m_hSocket, pState->m_hSocketWindow,

		WM_SOCKET_NOTIFY, lEvent) != SOCKET_ERROR;

}

图3出错相关代码

_AFXWIN_INLINE HINSTANCE AFXAPI AfxGetInstanceHandle()

	{ ASSERT(afxCurrentInstanceHandle != NULL);//第21行

		return afxCurrentInstanceHandle; }

------解决方案--------------------
以后出现这种问题一定要把调用堆栈贴出来。
