描述:
我的控件内有一主对话框，当执行到此对话框的析构时就出现错误，错误原因：
BOOL CWnd::DestroyWindow()
{
if (m_hWnd == NULL)
return FALSE;
CHandleMap* pMap = afxMapHWND();
ASSERT(pMap != NULL);
CWnd* pWnd = (CWnd*)pMap->LookupPermanent(m_hWnd);
#ifdef _DEBUG
HWND hWndOrig = m_hWnd;
#endif
#ifdef _AFX_NO_OCC_SUPPORT
BOOL bResult = ::DestroyWindow(m_hWnd);
#else //_AFX_NO_OCC_SUPPORT
BOOL bResult;
if (m_pCtrlSite == NULL)
bResult = ::DestroyWindow(m_hWnd);
else
bResult = m_pCtrlSite->DestroyControl();
#endif //_AFX_NO_OCC_SUPPORT
// Note that 'this' may have been deleted at this point,
// (but only if pWnd != NULL)
if (pWnd != NULL)
{
// Should have been detached by OnNcDestroy
#ifdef _DEBUG
ASSERT(pMap->LookupPermanent(hWndOrig) == NULL); //错在这一句。
#endif
}
else
{
#ifdef _DEBUG
ASSERT(m_hWnd == hWndOrig);
#endif
// Detach after DestroyWindow called just in case
Detach();
}
return bResult;
}
如何解决！！！！！！！！！！！！！！！！！！！！！？？？？？？？？？？？？
