如何象NT任务管理器那样得到进程占用内存的大小？在WINCE下又该如何做？]
不会是仅仅用GetProcessMemoryInfo吧？如果是，在WINCE下是不支持该函数的，那么是否有类似功能的api函数呢？

HANDLE hProcessSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
if (hProcessSnap == INVALID_HANDLE_VALUE)
{
CSystemanalyzer::PrintError(_T("CreateToolhelp32Snapshot for Process Error: %d\n"), GetLastError());
return FALSE;
}

ResetLiveTag(listProcess);

PROCESSENTRY32 ProcessEntry32;
ProcessEntry32.dwSize = sizeof(PROCESSENTRY32);
if (Process32First(hProcessSnap, &ProcessEntry32))
{
do
{
CProcess *pProcess = GetProcess(listProcess, ProcessEntry32.th32ProcessID);
if (pProcess == NULL)
{
pProcess = new CProcess;
listProcess.AddTail(pProcess);
pProcess->SetLiveFlag(-1);
}
else
pProcess->SetLiveFlag(1);

pProcess->SetProcessEntry(ProcessEntry32);
if (ProcessEntry32.th32ProcessID == 0)
continue;

HANDLE hProcess = OpenProcess(PROCESS_QUERY_INFORMATION, FALSE, ProcessEntry32.th32ProcessID);
if (hProcess == NULL)
{
CSystemanalyzer::PrintError(_T("打开进程(%d)失败！"), ProcessEntry32.th32ProcessID);
continue;
}

if (!GetProcessTimes(hProcess, &CreateTime ,&ExitTime ,&KernelTime, &UserTime))
CSystemanalyzer::PrintError(_T("GetProcessTimes Error: %d\r\n"), GetLastError());
else
pProcess->SetTime(CreateTime, ExitTime, KernelTime, UserTime);

PROCESS_MEMORY_COUNTERS PMCounter;
PMCounter.cb = sizeof(PROCESS_MEMORY_COUNTERS);
if (!GetProcessMemoryInfo(hProcess, &PMCounter, sizeof(PMCounter)))
CSystemanalyzer::PrintError(_T("GetProcessMemoryInfo Error: %d\n"), GetLastError());
pProcess->SetMemCounters(PMCounter);

DWORD dwPriority = GetPriorityClass(hProcess);
if (dwPriority == 0)
CSystemanalyzer::PrintError(_T("GetPriorityClass Error: %d\n"), GetLastError());

pProcess->SetPriority(dwPriority);
}
while (Process32Next(hProcessSnap, &ProcessEntry32));
}
else
CSystemanalyzer::PrintError(_T("ProcessEntry32First Error: %d\n"), GetLastError());

CloseHandle(hProcessSnap);
以上的代码枚举进程并得到进程的信息，，注意首先当前用户要有调试权限

vckbase里有篇文章,“剖析Windows任务管理器开发原理与实现 Author: TOo2y[原创]”可惜讲的不全，估计作者是让大家看他的主页。

楼上的已经把所有的进程都枚举出来了！
然后再根据枚举出来的每一个进程调用GetProcessMemoryInfo()函数，就
可以取得每一个进程所占用的内存的大小，然后再把得到的数据加到一个列表框
中应该就可以了！
希望对你有所帮助！
祝你成功！

下面是PROCESS_MEMORY_COUNTERS结构的详细解释，搂住可以看看，
The PROCESS_MEMORY_COUNTERS structure contains the memory statistics for a process.

typedef struct _PROCESS_MEMORY_COUNTERS {
DWORD cb;
DWORD PageFaultCount;
DWORD PeakWorkingSetSize;
DWORD WorkingSetSize;
DWORD QuotaPeakPagedPoolUsage;
DWORD QuotaPagedPoolUsage;
DWORD QuotaPeakNonPagedPoolUsage;
DWORD QuotaNonPagedPoolUsage;
DWORD PagefileUsage;
DWORD PeakPagefileUsage;
} PROCESS_MEMORY_COUNTERS;
typedef PROCESS_MEMORY_COUNTERS *PPROCESS_MEMORY_COUNTERS;

Members
cb
The size of the structure, in bytes.
PageFaultCount
The number of page faults.
PeakWorkingSetSize
The peak working set size.
WorkingSetSize
The current working set size.
QuotaPeakPagedPoolUsage
The peak paged pool usage.
QuotaPagedPoolUsage
The current paged pool usage.
QuotaPeakNonPagedPoolUsage
The peak nonpaged pool usage.
QuotaNonPagedPoolUsage
The current nonpaged pool usage.
PagefileUsage
The current pagefile usage.
PeakPagefileUsage
The peak pagefile usage.

还有 GetProcessMemoryInfor 函数的详细解释哦！^_^

GetProcessMemoryInfo
The GetProcessMemoryInfo function retrieves information about the memory usage of the specified process in the PROCESS_MEMORY_COUNTERS structure.

BOOL GetProcessMemoryInfo(
HANDLE Process, // handle to the process
PPROCESS_MEMORY_COUNTERS ppsmemCounters,
// structure that receives information
DWORD cb // size of the structure
);

Parameters
Process
Handle to the process.
ppsmemCounters
Pointer to the PROCESS_MEMORY_COUNTERS structure that receives information about the memory usage of the process.
cb
Specifies the size, in bytes, of the PROCESS_MEMORY_COUNTERS structure.
Return Value
If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

谢谢大家，其实我主要是想在WINCE上使用，不过还是要谢谢大家
分数我会考虑再开帖加分，欢迎继续讨论。
