检查退出标志
| BOOL CMyClass::IsDead()
{
return WaitForSingleObject(m_eventDead,0)==WAIT_OBJECT_0;
}
BOOL CMyClass::IsKilling()
{
return WaitForSingleObject(m_eventKill,0)==WAIT_OBJECT_0;
} |
在外部可以这样终止线程
| //check if dead
if(!IsDead()&&m_pThreadWrite!=NULL){
m_eventKill.SetEvent();
WaitForSingleObject(m_eventDead,INFINITE);
m_pThreadWrite=NULL;
} |
问：怎么实现IEnumString接口？
答：http://www.codeproject.com/wtl/customautocomplete_wtl.asp
IAutoComplete and custom IEnumString implementation for WTL dialogs
下面是我的基于数据库的IEnumString实现
