程序多次调用下面函数,前面没出错,后面调用时执行到Add()程序崩溃了
StringArray _LogStrAry;

void ShowAndWriteAlarmInfo(CString &AlarmInfo)
{
CString temp;
int nSize = _LogStrAry.GetSize() ;
if (nSize > 50) //多于50条就扔掉
{
/// modified by tim 2006.09.07 for 删除数组中数据时,必须防止和写log的线程冲突
//_LogStrAry.RemoveAll() ;
_LogCritical.Lock() ;
_LogStrAry.RemoveAll() ;
_LogCritical.Unlock() ;
//// end
}

temp.Empty();
temp =AlarmInfo;
_LogStrAry.Add(temp) ;     //将报警信息装入报警序列中

}

    在一个线程中,简单的使用add,RemoveAt不会出问题,但在多线程中,有的要add, 有的要RemoveAt,就会出问题
