--------------第一种方法------------
这种方法在中文输入法打开的情况下中西文都正常,
但我不想用这种费事的办法.

--------------第二种方法------------
这种方法用拷贝-粘贴的方式,在记事本下正常,
但在WORD下毫无反应!

代码

TGoodDictForm.SendKey();
var
i:integer;
focushld,windowhld:hwnd;

ch: byte;
begin
windowhld:

AttachThreadInput(GetCurrentThreadId,threadld,true);
getcursorpos(p);
//

Focushld:
=
WindowFromPoint(p);
//
返回句柄
AttachThreadInput(GetCurrentThreadId,threadld,false);
if
(focushld
=
0
)
or
(focushld
=
Self.Memo1.Handle)
then
begin
Exit;
end
;
SendMessage(focushld, WM_Paste,
0
,
0
);
end
;
//

要正確送出中文字符一定要依照微軟的IME機制, 單純用SendMessage 是不能夠的. 你可以把要送出的字符放在剪貼板中, 使用keybd_event 這個API送出 Ctrl 與 V 兩鍵的組合. 就能夠把中英文字串放到Word 軟件中,
keybd_event(VK_CONTROL, 0, 0, 0);
keybd_event(Ord('v'), 0, 0, 0);
keybd_event(Ord('v'), 0, KEYEVENTF_KEYUP, 0);
keybd_event(VK_CONTROL, 0, KEYEVENTF_KEYUP, 0);
uses sendkey32
{+ = Shift
^ = Control
% = Alt}
SendKeys('^X',true);
发送 Control+X消息

//
