Hello

  Here's code will return the all processes, I got it from Code central in borland site


unit GetProcess;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;

type
  TForm1 = class(TForm)
    Button1: TButton;
    ListBox1: TListBox;
    procedure Button1Click(Sender: TObject);
    procedure FormShow(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}
uses
  TLHelp32, PsApi;

function RunningProcessesList(List: TStrings): Boolean;

  function BuildListTH: Boolean;
  var
    SnapProcHandle: THandle;
    ProcEntry: TProcessEntry32;
    NextProc: Boolean;
  begin
    SnapProcHandle := CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
    if SnapProcHandle <> THandle(-1) then
    begin
      Result := True;
      ProcEntry.dwSize := Sizeof(ProcEntry);
      NextProc := Process32First(SnapProcHandle, ProcEntry);
      while NextProc do
      begin
        List.AddObject(ProcEntry.szExeFile, Pointer(ProcEntry.th32ProcessID));
        NextProc := Process32Next(SnapProcHandle, ProcEntry);
      end;
      CloseHandle(SnapProcHandle);
    end else
      Result := False;
  end;

  function BuildListPS: Boolean;
  var
    PIDs: array[0..1024] of DWORD;
    Handle: THandle;
    Needed: DWORD;
    I: Integer;
    ModuleFileName: array[0..MAX_PATH] of Char;
  begin
    Result := EnumProcesses(@PIDs, Sizeof(PIDs), Needed);
    if not Result then Exit;
    for I := 0 to (Needed div Sizeof(DWORD)) - 1 do
      if PIDs[I] <> 0 then
      begin
        Handle := OpenProcess(PROCESS_QUERY_INFORMATION or PROCESS_VM_READ, False, PIDs[I]);
        if Handle <> 0 then
        begin
          if GetModuleFileNameEx(Handle, 0, ModuleFileName, Sizeof(ModuleFileName)) = 0 then
            List.AddObject('[System]', Pointer(INVALID_HANDLE_VALUE))
          else
            List.AddObject(ModuleFileName, Pointer(PIDs[I]));
          CloseHandle(Handle);
        end;
      end;
  end;

begin
  Assert(Assigned(List));
  List.BeginUpdate;
  try
    List.Clear;
    if (Win32Platform = VER_PLATFORM_WIN32_NT) and (Win32MajorVersion = 4) then
      Result := BuildListPS
    else
      Result := BuildListTH;
  finally
    List.EndUpdate;
  end;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  RunningProcessesList(ListBox1.Items);
end;

procedure TForm1.FormShow(Sender: TObject);
begin
  Button1Click(nil);
end;

end.

Dear Mnasman ;-)

your code will return the Tabsheet with Process in the Taskmonitor but the Application TabSheet.

Its possible to get this form the Taskbar.

Claud, if you are looking for the runing tasks so just use GetTasksList function (JclSysInfo unit) from JCL:
http://delphi-jedi.org/Jedi:CODELIBJCL


Try this Exmaple:
function GetTasksList(const List: TStrings): Boolean;

  function EnumWindowsProc(Wnd: HWND; List: TStrings): Boolean; stdcall;
  var
    ParentWnd: HWND;
    ExStyle: DWORD;
    Caption: array [0..255] of Char;
  begin
    if IsWindowVisible(Wnd) then
    begin
      ParentWnd := GetWindowLong(Wnd, GWL_HWNDPARENT);
      ExStyle := GetWindowLong(Wnd, GWL_EXSTYLE);
      if ((ParentWnd = 0) or (ParentWnd = GetDesktopWindow)) and
        ((ExStyle and WS_EX_TOOLWINDOW = 0) or (ExStyle and WS_EX_APPWINDOW <> 0)) and
        (GetWindowText(Wnd, Caption, SizeOf(Caption)) > 0) then
          List.AddObject(Caption, Pointer(Wnd));
    end;
    Result := True;
  end;

begin
  Result := EnumWindows(@EnumWindowsProc, Integer(List));
end;

good luck

btw.. if you want to know how much cpu time all processes have been using, don't try to find some api call (i did that) it's a calculation..

check all processes and see how much time they used int a intervall

procedure TForm1.Button2Click(Sender: TObject);

Function x(t:_systemtime):String;
var s:string;
Begin
  s:= IntToStr(t.wYear);
  s:=s + '-' + IntToStr(t.wMonth);
  s:=s + '-' + IntToStr(t.wDay);
  s:=s + ' @ ' + IntToStr(t.wHour);
  s:=s + ':' + IntToStr(t.wMinute);
  s:=s + '.' + IntToStr(t.wSecond);
  result := s;
end;


var a,b,c,d : _filetime;
    t:_systemtime;
begin
//this is it!
 GetProcessTimes(GetCurrentProcess
                ,a
                ,b
                ,c
                ,d);


// specifies the process of interest
//    LPFILETIME lpCreationTime,     // when the process was created
//    LPFILETIME lpExitTime,     // when the process exited
//    LPFILETIME lpKernelTime,     // time the process has spent in kernel mode
//    LPFILETIME lpUserTime      // time the process has spent in user mode
//   );
  memo1.Clear;
  FileTimeToSystemTime(a,t); memo1.lines.add('Created ' + x(t));
  FileTimeToSystemTime(b,t); memo1.lines.add('Exited ' + x(t));
  FileTimeToSystemTime(c,t); memo1.lines.add('kernel ' + x(t));
  FileTimeToSystemTime(d,t); memo1.lines.add('user ' + x(t));

end;
