首先通过CreateToolhelp32Snapshot函数创建一个进程的快照，然后通过调用Process32First使用快照返回的句柄对进程进行遍历，相关的信息存放在PROCESSENTRY32结构类型的实例中，通过调用内部的一个函数GetProcessModule，获取对应的进程的模块名称，然后通过对进程地址空间信息的读取，从而获取相应的线程的ID等的信息。

二、主要实现代码：

获取进程地址空间内的相关信息：

hProcess = OpenProcess (PROCESS_ALL_ACCESS,
FALSE, pe32.th32ProcessID);

pfGetProcessMemoryInfo(hProcess,pmc,sizeof(pmc));


获取进程的模块信息：

BOOL CEmuteFileDlg::GetProcessModule(DWORD dwPID, DWORD dwModuleID, LPMODULEENTRY32 lpMe32, DWORD cbMe32)
{
BOOL bRet = FALSE;
BOOL bFound = FALSE;
HANDLE hModuleSnap = NULL;
MODULEENTRY32 me32 = {0};

// Take a snapshot of all modules in the specified process.

hModuleSnap = CreateToolhelp32Snapshot(TH32CS_SNAPMODULE, dwPID);


if (hModuleSnap == INVALID_HANDLE_VALUE)
return (FALSE);

// Fill the size of the structure before using it.

me32.dwSize = sizeof(MODULEENTRY32);

// Walk the module list of the process, and find the module of
// interest. Then copy the information to the buffer pointed
// to by lpMe32 so that it can be returned to the caller.

if (Module32First(hModuleSnap, &me32))
{
do
{
if (me32.th32ModuleID == dwModuleID)
{
CopyMemory (lpMe32, &me32, cbMe32);
bFound = TRUE;
}
}
while (!bFound && Module32Next(hModuleSnap, &me32));

bRet = bFound; // if this sets bRet to FALSE, dwModuleID
// no longer exists in specified process
}
else
bRet = FALSE; // could not walk module list

// Do not forget to clean up the snapshot object.

CloseHandle (hModuleSnap);

return (bRet);
}

三、提高权限：

BOOL EnableDebugPrivilege()

{
HANDLE hToken;
BOOL fOk=FALSE;
if(OpenProcessToken(GetCurrentProcess(),TOKEN_ADJUST_PRIVILEGES,&hToken))
{
TOKEN_PRIVILEGES tp;
tp.PrivilegeCount=1;
if(!LookupPrivilegeValue(NULL,SE_DEBUG_NAME,&tp.Privileges[0].Luid))
printf("Can't lookup privilege value.\n");
tp.Privileges[0].Attributes=SE_PRIVILEGE_ENABLED;
if(!AdjustTokenPrivileges(hToken,FALSE,&tp,sizeof(tp),NULL,NULL))
printf("Can't adjust privilege value.\n");
fOk=(GetLastError()==ERROR_SUCCESS);
CloseHandle(hToken);
}
return fOk;
}

四、后记：

我感觉信息获取的不够完整，比如说，我很想知道怎么才能获取进程的线程的模块名称，不知道那位大侠不吝赐教!
