Hi,
I trying to work with the APIs Process32First and Process32Next using Windows API Guide: Process32First Function as a sample.

For some reason that I don't figure out yeat, my code are not returning the expected value. I've look at my place, MSDN included, to check where is problem without success.

Because this, I'm asking for help here.

Thanks.

use Win32::API;

Win32::API::Struct->typedef( PROCESSENTRY32  => qw{
        LONG dwSize;
        LONG cntUsage;
        LONG th32ProcessID;
        LONG th32DefaultHeapID;
        LONG th32ModuleID;
        LONG cntThreads;
        LONG th32ParentProcessID;
        LONG pcPriClassBase;
        LONG dwFlags;
        CHAR szExeFile[260];
    });

Win32::API->Import('kernel32.dll', "HANDLE CreateToolhelp32Snapshot(DW
+ORD dwFlags,DWORD th32ProcessID)");
Win32::API->Import('kernel32.dll', "BOOL Process32First( HANDLE hSnaps
+hot, LPPROCESSENTRY32 lppe )" );
Win32::API->Import('kernel32.dll', "BOOL Process32Next( HANDLE hSnapsh
+ot, LPPROCESSENTRY32 lppe )" );

my $TH32CS_SNAPPROCESS = 0x2;

my $Snapshot    = undef;
my $ProcessInfo = Win32::API::Struct->new('PROCESSENTRY32');

$Snapshot = CreateToolhelp32Snapshot($TH32CS_SNAPPROCESS, 0);
  
$ProcessInfo->{dwSize} = Win32::API::Struct::sizeof ($ProcessInfo);
$Sucess = Process32First($Snapshot, $ProcessInfo);
print "Fist Process : $ProcessInfo->{szExeFile}\n"; #are returning not
