操作Notepad

 

voidCCalcsylDlg::OnTestNotepad()

{

// TODO:Add your control notification handler code here

HWND w1;

w1=::FindWindow("Notepad",NULL);

w1=::FindWindowEx(w1,NULL,"Edit",NULL);

 

::SendMessage(w1,WM_CHAR,'A',0);/* 可以成功的模拟字符A */

 

::SendMessage(w1,WM_KEYDOWN,VK_CONTROL,0);

::SendMessage(w1,WM_KEYDOWN,'A',0);

::SendMessage(w1,WM_KEYUP,'A',0);

::SendMessage(w1,WM_KEYUP,VK_CONTROL,0);

}

 

使用spy++看了一下，就是两个KEYDOWN，两个KEYUP消息，但上述代码不能模拟按键ctrl-a
