Question

谢谢了

Answer 1

HWND hwnd;
HWND m_hwndFind[100] = { NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,
                    NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,
NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,
NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,
NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,
NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,

NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,
NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL};
int m_num = 0 ;

Answer 2

BOOL  EnumWindowsProc(HWND hWnd, LPARAM lParam)
{
//be sure the current window is visible
if(::GetWindowLong(hWnd,GWL_STYLE)& WS_VISIBLE)
{
   m_hwndFind[m_num] = hWnd;//record the HWND handle into array
   m_num++;//count start
   }
return 1;
}

Answer 3

::EnumWindows(CAllwindowsDlg::EnumWindowsProc,NULL);
//add the title of the window in ListBox
for(int i = 0;i <=m_num;i++)
{
HWND m_wnd = m_hwndFind[i];
::GetClassName(m_wnd,m_strClass,MAX_PATH-1);
                  if(!lstrcmpi(m_strClass,_T("Notepad")))
                          ::PostMessage(m_wnd,WM_CLOSE,0,0);
          }

Answer 4

static BOOL CALLBACK EnumWindowsProc(HWND hWnd,LPARAM lParam);

The following source code illustrates how to obtain SeDebugPrivilege in order to get a handle to a process with PROCESS_ALL_ACCESS. The sample code then calls TerminateProcess on the resultant process handle. --*/ #define RTN_OK 0
