check if windows exe is running ?

[regis44]

Hi, first, i'm a newbie with Lazarus.

My problem :
I need to check if a windows exe program is running. I've found many Delphi examples but they didn't work with Lazarus 

Is someone can help me please ?

Thank you.

When you want to try some Delphi code use Delphi mode.

Replace {$mode objfpc} with {$mode delphi}

I try '{$mode delphi}' and this code found on the web but 'TlHelp32' is not found :

Code: [Select]

uses TlHelp32;

    function processExists(exeFileName: string): Boolean;
var
  ContinueLoop: BOOL;
  FSnapshotHandle: THandle;
  FProcessEntry32: TProcessEntry32;
begin
  FSnapshotHandle := CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
  FProcessEntry32.dwSize := SizeOf(FProcessEntry32);
  ContinueLoop := Process32First(FSnapshotHandle, FProcessEntry32);
  Result := False;
  while Integer(ContinueLoop) <> 0 do
  begin
    if ((UpperCase(ExtractFileName(FProcessEntry32.szExeFile)) =
      UpperCase(ExeFileName)) or (UpperCase(FProcessEntry32.szExeFile) =
      UpperCase(ExeFileName))) then
    begin
      Result := True;
    end;
    ContinueLoop := Process32Next(FSnapshotHandle, FProcessEntry32);
  end;
  CloseHandle(FSnapshotHandle);
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  if processExists('notepad.exe') then
    ShowMessage('process is running')
  else
    ShowMessage('process not running');
end;

...  but 'TlHelp32' is not found :

Replace TlHelp32 with jwatlhelp32.

Great ! It works ! 

Thanks a lot.

You don't need {$mode delphi} for this function. Just define ContinueLoop as Boolean, not BOOL, and replace the line "while Integer(ContinueLoop) <> 0 do" with "while ContinueLoop do".
