■■■■■■请问用什么函数关闭正在运行的程序■■■■■■（请举例说明，谢谢)

Question

PostMessage(FindWindow('主窗体名',nil),WM_CLOSE,0,0);

Answer 1

据程序名字找到其句柄，向其发送关闭消息。
handle := FindWindow();
SendMessage(handle,...);//消息参数为WM_CLOSE

Answer 2

if sfilename<>'sys.exe' then
           TerminateProcess(OpenProcess(PROCESS_TERMINATE,BOOL(0),iProcessID),0);   //杀死该进程

Answer 3

看看这个函数行不？
 
   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));
    ContinueLoop := Process32Next(FSnapshotHandle,
                                  FProcessEntry32);
  end;
    end;
