VC++ 如何进程名取PID

VC++ 如何进程名取PID

Answer 1

#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++ )
if( aProcesses[i] != 0 )
PrintProcessNameAndID( aProcesses[i] );
}
这个是MSDN上的例子，里面包括了枚举PID与进程名，你看懂这个例子就什么都知道了。

用CreateToolhelp32Snapshot这个函数吧！感觉这个还比较好用点，而且msdn上有完整的例子代码。
