不存在从int转换到CMapWordToPtr的适当构造函数怎么改？

1.在c++编写中，出现不存在从int转换到CMapWordToPtr的适当构造函数的错误提示
2.

#include "StdAfx.h"

#include "CoolControlsManager.h"

// If you don't want to see extra TRACE diagnostics,
// modify the line below to: #define CCM_TRACE
#define CCM_TRACE TRACE

#define CCM_TIMER_VAL 100        // 100 ms timer period seems to be good enough...
#define MAX_CLASSNAME 64         // Length of buffer for retrieving the class name

////////////////////////////////////////////////////////////////////////
// CCMControl static members initialization

HWND CCoolControlsManager::CCMControl::m_hWndOld = NULL;
CMapPtrToPtr CCoolControlsManager::m_ctrlMap = 10;
CMapPtrToPtr CCoolControlsManager::m_dlgMap = 10;
BOOL CCoolControlsManager::m_bEnabled = true;

// Changed 02.03.1999 Mike Walter
CMapWordToPtr CCoolControlsManager::m_threadMap = 10;     

///////////////////////////////////////////////////////////////////////
// Here is the one and only CCoolControlsManager object
static CCoolControlsManager g_ctrlManager;

CCoolControlsManager& GetCtrlManager()
{
   return g_ctrlManager;
}

在CMapPtrToPtr中加个构造函数，int作为参数。这样就可以使int转换成CMapPtrToPtr了。
