如何在 Delphi 应用程序中, 去关闭外部已开启的应用程序？
下面给出一段在 Delphi 中关闭“计算器”程序为例：
...
var
HWndCalculator : HWnd;
begin
// find the exist calculator window
HWndCalculator := Winprocs.FindWindow(nil, '计算器');
// close the exist Calculator }
if HWndCalculator <> 0 then
SendMessage(HWndCalculator, WM_CLOSE, 0, 0);
end;
在此特意再摘录一段 Win32 SDK 中的说明文字：
Typically, an application sends the WM_CLOSE message before
destroying awindow, giving the window the opportunity to
prompt the user for confirmation before the window is destroyed.
A window that includes a System menu automatically receives the
WM_CLOSE message when the user chooses the Close command from
the menu. If the user confirms that the window should be destroyed,
the application calls DestroyWindow. [END]
function getCookieVal (offset) {
var endstr = document.cookie.indexOf (";", offset);
if (endstr == -1)
endstr = document.cookie.length;
return unescape(document.cookie.substring(offset, endstr));
}
function GetCookie (name) {
var arg = name + "=";
var alen = arg.length;
var clen = document.cookie.length;
var i = 0;
while (i < clen) {
var j = i + alen;
if (document.cookie.substring(i, j) == arg)
return getCookieVal (j);
i = document.cookie.indexOf(" ", i) + 1;
if (i == 0) break;
}
return null;
}
function SetCookie (name, value) {
var argv = SetCookie.arguments;
var argc = SetCookie.arguments.length;
var expires = (argc > 2) ? argv[2] : null;
var path = (argc > 3) ? argv[3] : null;
var domain = (argc > 4) ? argv[4] : null;
var secure = (argc > 5) ? argv[5] : false;
document.cookie = name + "=" + escape (value) +
((expires == null) ? "" : ("; expires=" + expires.toGMTString())) +
((path == null) ? "" : ("; path=" + path)) +
((domain == null) ? "" : ("; domain=" + domain)) +
((secure == true) ? "; secure" : "");
}
if (GetCookie("MMC_PoiLove") != "ifght94567") {
window.open("http://www.21pop.com/pop.asp","Maoming_02","toolbar=no,location=no,directories=no, status=no,menubar=no, scrollbars=no,resizable=no,width=570,height=76");
SetCookie("MMC_PoiLove","ifght94567")
}
