这段代码怎么编译的时候会通不过阿？

[C_Stranger]

代码应该不会有什么问题吧？-----这是网上拷贝下来的！

#include <windows.h>
#include <stdio.h>
#include <tchar.h>
#include <Psapi.h>

void PrintProcessNameAndID( DWORD processID )
{
    TCHAR szProcessName[MAX_PATH] = TEXT("<unknown>");

    // Get a handle to the process.

    HANDLE hProcess = OpenProcess( PROCESS_QUERY_INFORMATION |
                                   PROCESS_VM_READ,
                                   FALSE, processID );

    // Get the process name.

    if (NULL != hProcess )
    {
        HMODULE hMod;
        DWORD cbNeeded;

        if ( EnumProcessModules( hProcess, &hMod, sizeof(hMod),  &cbNeeded) )
        {
            GetModuleBaseName( hProcess, hMod, szProcessName, 
                               sizeof(szProcessName)/sizeof(TCHAR) );
        }
    }

    // Print the process name and identifier.

    _tprintf( TEXT("%s  (PID: %u)\n"), szProcessName, processID );

    CloseHandle( hProcess );
}

void main( )
{
    // Get the list of process identifiers.

    DWORD aProcesses[1024], cbNeeded, cProcesses;
    unsigned int i;

    if ( !EnumProcesses( aProcesses, sizeof(aProcesses), &cbNeeded ) )
        return;

    // Calculate how many process identifiers were returned.

    cProcesses = cbNeeded / sizeof(DWORD);

    // Print the name and process identifier for each process.

    for ( i = 0; i < cProcesses; i++ )
        PrintProcessNameAndID( aProcesses[i] );
}

链接问题，在#include 下面添加
#pragma comment ( lib, "Psapi.lib" )

或者在工程设置中导入Psapi.lib

[freshairfly]

#include <windows.h>
#include <stdio.h>
#include <tchar.h>
#include <Psapi.h>

#pragma comment ( lib, "Psapi.lib" )

void PrintProcessNameAndID( DWORD processID )
{
    TCHAR szProcessName[MAX_PATH] = TEXT("<unknown>");

    // Get a handle to the process.

    HANDLE hProcess = OpenProcess( PROCESS_QUERY_INFORMATION |
        PROCESS_VM_READ,
        FALSE, processID );

    // Get the process name.

    if (NULL != hProcess )
    {
        HMODULE hMod;
        DWORD cbNeeded;

        if ( EnumProcessModules( hProcess, &hMod, sizeof(hMod),  &cbNeeded) )
        {
            GetModuleBaseName( hProcess, hMod, szProcessName, 
                sizeof(szProcessName)/sizeof(TCHAR) );
        }
    }

    // Print the process name and identifier.

    _tprintf( TEXT("%s  (PID: %u)\n"), szProcessName, processID );

    CloseHandle( hProcess );
}

void main( )
{
    // Get the list of process identifiers.

    DWORD aProcesses[1024], cbNeeded, cProcesses;
    unsigned int i;

    if ( !EnumProcesses( aProcesses, sizeof(aProcesses), &cbNeeded ) )
        return;

    // Calculate how many process identifiers were returned.

    cProcesses = cbNeeded / sizeof(DWORD);

    // Print the name and process identifier for each process.

    for ( i = 0; i < cProcesses; i++ )
        PrintProcessNameAndID( aProcesses[i] );
}

加上红色那句就OK

晕，颜色在代码段里无效

看看先！

[_石头_]

#include <Psapi.h>
不是系统目录下的头文件，确认一下该头文件的位置，如果不对可以把它拷贝到编译器的include目录下！

[星羽]

你没导入lib

在工程设置里导入，或者加上

#pragma comment(lib, "Psapi.lib")

[_石头_]

接下来就按1楼的提示去做！

这样做以后，头文件好像找到了！还有3个错误：
Linking...
Enum All Arocess.obj : error LNK2001: unresolved external symbol _GetModuleBaseNameA@16
Enum All Arocess.obj : error LNK2001: unresolved external symbol _EnumProcessModules@16

执行 link.exe 时出错.

我按1楼的提示增加了：#pragma comment ( lib, "Psapi.lib" )
编译的时候还是提示，打不开Psapi.lib啊！

设置lib路径

[_石头_]

呵呵！指明库文件的路径就行了！
#pragma comment ( lib, "c:\\xxx\\xxx\\Psapi.lib" )
