Question

我想关闭一些运行的进程(运行之中),用什么api函数,怎么用?
望请教

Answer 1

function KillTask(ExeFileName: string): integer;
const
  PROCESS_TERMINATE=$0001;
var
  ContinueLoop: BOOL;
  FSnapshotHandle: THandle;
  FProcessEntry32: TProcessEntry32;
begin
  result := 0;  FSnapshotHandle := CreateToolhelp32Snapshot
                     (TH32CS_SNAPPROCESS, 0);
  FProcessEntry32.dwSize := Sizeof(FProcessEntry32);
  ContinueLoop := Process32First(FSnapshotHandle,
                                 FProcessEntry32);  while integer(ContinueLoop) <> 0 do
  begin
    if ((UpperCase(ExtractFileName(FProcessEntry32.szExeFile)) =
         UpperCase(ExeFileName))
     or (UpperCase(FProcessEntry32.szExeFile) =
         UpperCase(ExeFileName))) then
      Result := Integer(TerminateProcess(OpenProcess(
                        PROCESS_TERMINATE, BOOL(0),
                        FProcessEntry32.th32ProcessID), 0)); //关闭进程 
    ContinueLoop := Process32Next(FSnapshotHandle,
                                  FProcessEntry32);
  end;
    end;

Answer 2

TProcessEntry32
是在哪个单元里面调用的?
