关于启动类属成员函数作线程执行体的问题

[dch4890164]

UINT Robot::RobotMotionOnTracj(LPVOID pParam)
{
return NULL;
}
UINT Robot::RobRandMotionThread(LPVOID pParam)
{
return NULL;
}
void Robot::RobotMotion(int mode)
{
if (mode == 1)
{
_beginthreadex(NULL,0,(unsigned int (__stdcall *)(void *))RobRandMotionThread,(void *)this,NULL,RandThreadID);
return;
}
if (mode == 2)
{
_beginthreadex(NULL,0,(unsigned int(__stdcall *)(void *))RobotMotionOnTracj,0,&TaskAim,RandThreadID);
return;
}

}
代码如上
我已经在设置里设置了使用多线程动态库
可是编译的时候提示
E:\程序project\ACS\Robot.cpp(41) : error C2440: 'type cast' : cannot convert from '' to 'unsigned int (__stdcall *)(void *)'
None of the functions with this name in scope match the target type
E:\程序project\ACS\Robot.cpp(46) : error C2440: 'type cast' : cannot convert from '' to 'unsigned int (__stdcall *)(void *)'
None of the functions with this name in scope match the target type
-----------------------------------------------------------
为什么？？

[yjgx007]

The both RobRandMotionThread and RobotMotionOnTracj functions should return 'void' type

[dch4890164]

还是不行，同样的错误

[yjgx007]

They also should be as static function of the class.

[dch4890164]

我不想那样，那样我就可以不用成员函数了，全局函数就可以达到目的了！

[dch4890164]

你是对的，我明白了你的意思！
问题已经搞定
谢谢
