VC中如何察看当前运行的所有线程，并切换到该线称？？
我一个程序的某个线程不停的创建、退出。（在vc的output窗口不停的显示）。。。程序比较大，也不是我写的。。但是这个线程创建、退出似乎造成了一些问题。
我不知道如何在vc下察看当前进程的所有线程，并切换过去。
我在网上一篇文章看到如下：
“我们可以用Visual Studio调试器附上这个应用程序，切换到这个线程下“ ----- 请问具体该如何做???

查看有哪些线程还好办，要切换过去比较难办。因为线程的调度是由操作系统控制的。Top

vs2003：调试－》窗口－》线程，然后双击显示线程的条目即可切换。要处于调试状态才能找到。Top

DentistryDoctor说得对，切换的话也只能是切换到此线程当前执行到的源代码，并不是执行流程的切换。Top

1、Thread Walking （From MSDN，参考http://msdn.microsoft.com/library/default.asp?url=/library/en-us/perfmon/base/tool_help_library.asp）
A snapshot that includes the thread list contains information about each thread of each currently executing process. You can retrieve information for the first thread in the list by using the Thread32First function. After retrieving the first thread in the list, you can retrieve information for subsequent threads by using the Thread32Next function. Thread32First and Thread32Next fill a THREADENTRY32 structure with information about individual threads in the snapshot.
You can enumerate the threads of a specific process by taking a snapshot that includes the threads and then by traversing the thread list, keeping information about the threads that have the same process identifier as the specified process.
You can retrieve an extended error status code for Thread32First and Thread32Next by using the GetLastError function.
Note The contents of the th32ThreadID member of THREADENTRY32 is a thread identifier and can be used by any functions that require a thread identifier.
2、SwitchToThread APITop

1.toolhelp32 枚举特定进程的所有线程列表
#include <windows.h>
#include <tlhelp32.h>
#include <stdio.h>
BOOL RefreshThreadList (DWORD dwOwnerPID)
{
HANDLE hThreadSnap = NULL;
BOOL bRet = FALSE;
THREADENTRY32 te32 = {0};
// Take a snapshot of all threads currently in the system.
hThreadSnap = CreateToolhelp32Snapshot(TH32CS_SNAPTHREAD, 0);
if (hThreadSnap == INVALID_HANDLE_VALUE)
return (FALSE);
// Fill in the size of the structure before using it.
te32.dwSize = sizeof(THREADENTRY32);
// Walk the thread snapshot to find all threads of the process.
// If the thread belongs to the process, add its information
// to the display list.
if (Thread32First(hThreadSnap, &te32))
{
do
{
if (te32.th32OwnerProcessID == dwOwnerPID)
{
printf( "\nTID\t\t%d\n", te32.th32ThreadID);
printf( "Owner PID\t%d\n", te32.th32OwnerProcessID);
printf( "Delta Priority\t%d\n", te32.tpDeltaPri);
printf( "Base Priority\t%d\n", te32.tpBasePri);
}
}
while (Thread32Next(hThreadSnap, &te32));
bRet = TRUE;
}
else
bRet = FALSE; // could not walk the list of threads
// Do not forget to clean up the snapshot object.
CloseHandle (hThreadSnap);
return (bRet);

threadproc 中 启动 一个事件通知， 在主线成 中 waitmultiobject ,SwitchToThread 可以让 system 切换到 下一个 thread ,
case THREAD1 :
//if not you need ,switch to next thread
SwitchToThread();
break;
case THREAD2:

很难的吧？？我没想过，要到进程里再看线程，大哥你没事情做了吧？？？真是蚂蚁体内找五脏啊Top

人家是问调试器怎么来选择不同的目标thread来调试，不是程序里面切换thread
真是服了楼上几位兄弟
如果要作多县城调试，vs ide不是一个很好的工具。用windbg吧。切换thread用简单的
~thread number
就可以了
详细的可以参考：

先break下来，然后点
菜单：调试->窗口->线程
会看到所有线程列表，在线程上点右键，有个“切换到”菜单。
vs2003和2000都有。Top
