how can I list all the processes in the system

[xxs]

I have writen some codes as follow：

#include <windows.h>
#include <tlhelp32.h>
#include <stdio.h>

// Forward declarations:

BOOL GetProcessList( );
BOOL ListProcessModu les( DWORD dwPID );
BOOL KillProcessFrom Name(LPCTSTR name);
void printError( TCHAR* msg );

//
void main( )
{
GetProcessList( );
}

//获�进程信 �
BOOL GetProcessList( )
{
HANDLE hProcessSnap;
HANDLE hProcess;
PROCESSENTRY32 pe32;
DWORD dwPriorityClass ;

// Take a snapshot of all processes in the system.
hProcessSnap = CreateToolhelp3 2Snapshot( TH32CS_SNAPPROC ESS, 0 );
if( hProcessSnap == INVALID_HANDLE_ VALUE )
{
printError( "CreateToolhelp 32Snapshot (of processes)" );
return( FALSE );
}

// Set the size of the structure before using it.
pe32.dwSize = sizeof( PROCESSENTRY32 );

// Retrieve information about the first process,
// and exit if unsuccessful
if( !Process32First ( hProcessSnap, &pe32 ) )
{
printError( "Process32First " ); // Show cause of failure
CloseHandle( hProcessSnap ); // Must clean up the snapshot
object!
return( FALSE );
}

// Now walk the snapshot of processes, and
// display information about each process in turn
do
{
printf( "\n
\n============= =============== =============== ==========" );
printf( "\nPROCESS NAME: %s", pe32.szExeFile );

printf( "\n-----------------------------------------------------" );

// Retrieve the priority class.
dwPriorityClass = 0;
hProcess = OpenProcess( PROCESS_ALL_ACC ESS, FALSE,
pe32.th32Proces sID );
if( hProcess == NULL )
printError( "OpenProces s" );
else
{
dwPriorityClass = GetPriorityClas s( hProcess );
if( !dwPriorityClas s )
printError( "GetPriorityCla ss" );
CloseHandle( hProcess );
}
//进程的相关 信�
printf( "\n process ID = 0x%08X", pe32.th32Proces sID );//id�
// List the modules and threads associated with this process
ListProcessModu les( pe32.th32Proces sID );
// ListProcessThre ads( pe32.th32Proces sID );

} while( Process32Next( hProcessSnap, &pe32 ) );

CloseHandle( hProcessSnap );
return( TRUE );
}
//模�信�
BOOL ListProcessModu les( DWORD dwPID )
{
HANDLE hModuleSnap = INVALID_HANDLE_ VALUE;
MODULEENTRY32 me32;
hModuleSnap = CreateToolhelp3 2Snapshot( TH32CS_SNAPMODU LE, dwPID );
if(hModuleSnap == INVALID_HANDLE_ VALUE)
{
printError( "CreateToolhelp 32Snapshot (of Modules)" );
return( FALSE );
}

// Set the size of the structure before using it.
me32.dwSize = sizeof( MODULEENTRY32 );

// Retrieve information about the first module,

if( !Module32First( hModuleSnap, &me32 ) )
{
printError( "Module32Fi rst" ); // Show cause of failure
CloseHandle( hModuleSnap ); // Must clean up the snapshot

return( FALSE );
}

printf( "\n executable = %s\n", me32.szExePath );
CloseHandle( hModuleSnap );
return( TRUE );

}

//kill the special process

//错误处�
void printError( TCHAR* msg )
{
DWORD eNum;
TCHAR sysMsg[256];
TCHAR* p;

eNum = GetLastError( );
FormatMessage( FORMAT_MESSAGE_ FROM_SYSTEM |
FORMAT_MESSAGE_ IGNORE_INSERTS,
NULL, eNum,
MAKELANGID(LANG _NEUTRAL, SUBLANG_DEFAULT ), // Default
language
sysMsg, 256, NULL );

// Trim the end of the line and terminate it with a null
p = sysMsg;
while( ( *p 31 ) || ( *p == 9 ) )
++p;
do { *p-- = 0; } while( ( p >= sysMsg ) &&
( ( *p == '.' ) || ( *p < 33 ) ) );

// Display the message
printf( "\n WARNING: %s failed with error %d (%s)", msg, eNum,
sysMsg );
}

I can get some processes' location,but I can't get all,such as
svchost.
How can I get all processes' location?

Thank you!

Sorry, this is off-topic here, try one of the microsoft.publi c.*
groups, such as microsoft.publi c.win32.program mer.

Thank you!

Off topic, but most likely you don't have enough privilege to peek into
system processes such as svchost.

Kindly snip quoted text appropriately. You did not need to quote
nearly 200 lines for a one sentence response.
