为什么我在程序中已经声明了#include 还是不能用_beginthreadex

[wxnet]

看process.h头文件，里面好像需要用到了一个宏_MT,但我在编译环境中定义了这个宏之后，有出现了一堆如下的错误提示，请问如何解决?

少了.lib文件了吧

[yym314]

project->setting->C/C++->use run_time libray
make sure "multithread..." selected

[双杯献酒]

_beginthreadex要求Win2000,
请在StdAfx.h开头
#define _MSC_VER 0x5000
表示Win2000
或者在
菜单 Project-->Settings-->C/C++ --->General下
Perprocessor Definitions中添加
_MSC_VER=0x5000

[sxmzmxh]

使用C/C++运行时期多线程库，默认是单线程的

[Richuen22]

在project->setting->C/C++->Category->Code Generation后，在use run_time libray选Debug multithread dll

[liuhongyong]

up

[zhouyong0371]

hread.obj : error LNK2001: unresolved external symbol __beginthreadex说明对应的.lib文件没有包含。
project->setting->link->Object/Library Modules下添加 LIBCMT.LIB
其他的错误：嗬嗬，慢慢看吧，

多谢各位，这是我在CSDN上第一个靠近技术方面的问题被解决。
虽然我的原因是project->setting->C/C++->use run_time libray没有设置。但各位都有给分了，多谢。
