            我是想在界面点击鼠标左键后中断JSearch线程，但是主程序不能接收鼠标的消息，一点鼠标就死机。请高手帮我解决，我万分感谢，也会帮帮忙解决我能解决的问题的。我是新来的，请多照顾。

首先，创建线程是用_beginthreadex或者CreateThread，CreateProcess是创建进程。其次，用_beginthreadex或者CreateThread成功后，将得到一个线程句柄,用SuspendThread和ResunmeThread可以控制该线程的挂起和执行状态。如果你要控制进程状态的话，你可以采用进程间通讯(IPC)的方法,对于棋类游戏，采用多线程控制很有必要。另外，TerminateProcess、TerminateThread之类的函数请尽量不要调用,而是让线程自然return 比较友好，因为这样可以正确释放我们之前的资源。你可以设定一个线程安全的全局变量控制线程退出。用waitformultiobject/msgwaitformultiobject控制线程的顺序安全退出。
