更新:我添加了以下代码:
function TSettingsForm.AppDataPath: string;
//CSIDL_APPDATA Individual user Data
//CSIDL_COMMON_APPDATA Common to Computer Data
// works so long as people have at least IE 4. (and Win95 or better)
var
r: Bool;
path: array[0..Max_Path] of Char;
begin
r := ShGetSpecialFolderPath(0, path, CSIDL_APPDATA, False) ;
if r then result := path
else result := '';
end;
而且我已经更改了 setinifilename 函数(见下文)。它不会创建文件夹结构。
--结束更新--
我落后于时代,不知道该做什么,不该做什么。这就是我当前保存软件设置的方式。我只是在没有以管理员身份登录的 Vista 上测试它,它给了我一个错误消息无法写入 ini 文件。所以我猜我应该将数据写入数据文件夹?我以前从没用过vista/win7,希望这个软件能兼容windows 2K+。我应该怎么做才能保存设置。我也真的不想弄乱注册表,因为你添加到它的每一点都会减慢计算机的速度......(或者看起来)
感谢您的任何意见。
