请问如何得到一个窗口句柄,然后发消息给它

Question

Findwindow我是知道的,
但是对如记事本这类的窗口我就不知道如何处理了,
好象有类从任务进程获取指定窗口名柄的方法,请指教

Answer 1

HWND hwndNotepad = ::FindWindow("Notepad",NULL);
HWND hwndEdit = ::FindWindowEx(hwndNotepad,NULL,"Edit",NULL);
::SendMessage(hwndEdit,WM_SETTEXT,0,(LPARAM)(LPCTSTR)"Hello Word!");

Answer 2

FindWindowEx(NULL,NULL,"窗口类名","窗口标题")
SendMessage(...),PostMessage()

Answer 3

HWND hwndNotepad = ::FindWindow("Notepad",NULL);
HWND hwndEdit = ::FindWindowEx(hwndNotepad,NULL,"Edit",NULL);
::SendMessage(hwndEdit,WM_SETTEXT,0,(LPARAM)(LPCTSTR)"Hello Word!");

Answer 4

还有一种方法供参考：
SetCapture()
WindowFromPoint()
ReleaseCapture()

Answer 5

哦，忘了发消息了
hwndEdit=WindowFromPoint()；
再用papaya_stone(^_^)shentong(^_^) 老兄的代码：
::SendMessage(hwndEdit,WM_SETTEXT,0,(LPARAM)(LPCTSTR)"Hello Word!");
