我想寫一程序去控制notepad的按鈕,但不知為何沒反應??請指教.
procedure TForm1.Button1Click(Sender: TObject);
var
myhwnd:HWND;
begin
myhwnd:=FindWindowEx(FindWindow(nil,'test.txt - 記事本'),0,'nil','檔案');
SendMessage(myhwnd, BM_CLICK ,0,0);
end;

myhwnd:=FindWindowEx(FindWindow(nil,'test.txt - 記事本'),0,'nil','檔案');

nil不用加引号

var
myhwnd : Thandle;
begin
myhwnd := FindWindow(nil, ''test.txt - 記事本');
if myhwnd =0 then
begin
SHowMessage('没打开记事本');
Exit;
end;
SendMessage(myhwnd, BM_CLICK, 0, 0);
end;
