问题描述
第二次尝试收到一个问题的答案。非常抱歉，但是我的英文很糟糕，所以我很难解释一下我想要的，特别是技术问题：_（
我再次尝试这个时候有一个具体的例子，对我来说是有必要的。
DelphiXe，Win7x64。Windows Uac是On，用户使用管理员的权限。
应该从另一个地方复制文件的程序（示例）
她应该以通常的方式启动（不是代表管理员）因此，不需要粘贴到一个宣言（*。rc）EXE文件（其中授予管理员的权限 - 更多的启动请求）
复制应该以常规方式执行 - 管理员的权限只有在需要的情况下才应该被请求，而不重新启动程序。
问题（代码中标有*）：
1.如何定义Windows UAC是否存在于系统中以及是否启用
2.如何获取管理员权限（的dedu ce消息Windows UAC）仅在需要的情况下实际获得该程序的许可证而不重新启动它
示例 - 文件管理器的远程管理器（或总指挥官 '）可以这样做 - 他们在通常的启动时复制文件（而不是代表管理员），并且只有当业务涉及系统文件夹时才引起查询UAC。因此，程序不会重新启动，并首先发出预防。
P.S。非常感谢我的帖子的帮助和编辑。

例如在
从e：\MyNew.txt中的d：\MyTest.txt
而有关权限查询UAC的消息应该出现在例如
从d：\MyTest.txt c：\Windows\MyNew.txt
您可以使用此功能检查UAC是否活动

函数IsUACActive：Boolean;

//有一个机会是活跃的，因为我们在Vista或Windows 7上。现在检查注册表
如果CheckWin32Version（6，0）然后

if（Result = 0）和（eoWait in Options）然后
begin
GetExitCodeProcess（ShellExecuteInfo.hProcess，ExitCode）;

（not Application.Terminated）do
begin
sleep（50）;
GetExitCodeProcess（ShellExecuteInfo.hProcess，ExitCode）;
结束
结果：= ExitCode;

结束
要运行高级隐藏进程并等待退出：
$ b $执行文件（Self.Handle，'Filename'，'Parameters'，[eoHide，eoWait，eoElevate]）; b
希望这有助于
It is the second attempt to receive the answer on a question. Very much I apologise, but my English very bad, therefore it is very difficult to me to explain that I want, especially in technical questions :_(
I try once again, this time with a concrete example, that it is necessary for me.
DelphiXe, Win7x64. Windows Uac is On. The user works with the rights of the Administrator.
The program (example) which should copy files from one place in another is given.She should be started by usual way (not on behalf of the Admin). Therefore gluing to a manifes(*.rc) EXE-file (which grants the rights of the Admin - requests at start more truly) is not required.Copying should be carried out by usual way - the rights of Admin should be requested only in case of need and without restart of the program.
Problem (in a code are marked "*"):1. How to define that Windows UAC is present at system and whether it is Enabled2. How to get the licence of Admin right (to deduce message Windows UAC) only in case of need and actually to get this licence for the program not restarting it
Example - file managers 'Far manager' (or 'Total Commander') can so to do - they copy files at usual start (not on behalf of the Admin), and cause inquiry UAC only when business concerns system folders. Thus programs are not restarted and at first give out the prevention.
P.S. It is grateful for the help and editing of my posts.

// The problem to request the rights (and to include) only when they are necessary
if OpenDialogFROM.Execute then if SaveDialogTO.Execute then
if FileExists(OpenDialogFROM.FileName)=true then
if TestPathWrite(ExtractfilePath(SaveDialogTO.FileName))=true then

end;
end.
Copying will be normal for example at
From d:\MyTest.txt in e:\MyNew.txt
And the message with inquiry of rights UAC should to appear for example at
From d:\MyTest.txt in c:\Windows\MyNew.txt
You can check if UAC is active using this function
interface
uses
Registry, SysUtils;
function IsUACActive: Boolean;
implementation
function IsUACActive: Boolean;
var
Reg: TRegistry;
begin
Result := FALSE;
// There's a chance it's active as we're on Vista or Windows 7. Now check the registry
if CheckWin32Version(6, 0) then
begin
Reg := TRegistry.Create;
try
Reg.RootKey := HKEY_LOCAL_MACHINE;
if Reg.OpenKeyReadOnly('SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System') then
begin
if (Reg.ValueExists('EnableLUA')) and (Reg.ReadBool('EnableLUA')) then
Result := TRUE;
end;
finally
FreeAndNil(Reg);
end;
end;
end;
You can run an elevated process using the following function:
...
interface
uses
Windows, ShellAPI, Forms;
type
TExecuteFileOption = (
eoHide,
eoWait,
eoElevate
);
TExecuteFileOptions = set of TExecuteFileOption;
function ExecuteFile(Handle: HWND; const Filename, Paramaters: String; Options: TExecuteFileOptions): Integer;
implementation
function ExecuteFile(Handle: HWND; const Filename, Paramaters: String; Options: TExecuteFileOptions): Integer;
var
ShellExecuteInfo: TShellExecuteInfo;
ExitCode: DWORD;
begin
Result := -1;
ZeroMemory(@ShellExecuteInfo, SizeOf(ShellExecuteInfo));
ShellExecuteInfo.cbSize := SizeOf(TShellExecuteInfo);
ShellExecuteInfo.Wnd := Handle;
ShellExecuteInfo.fMask := SEE_MASK_NOCLOSEPROCESS;
if (eoElevate in Options) and (IsUACActive) then
ShellExecuteInfo.lpVerb := PChar('runas');
ShellExecuteInfo.lpFile := PChar(Filename);
if Paramaters <> '' then
ShellExecuteInfo.lpParameters := PChar(Paramaters);
// Show or hide the window
if eoHide in Options then
ShellExecuteInfo.nShow := SW_HIDE
else
ShellExecuteInfo.nShow := SW_SHOWNORMAL;
if ShellExecuteEx(@ShellExecuteInfo) then
Result := 0;
if (Result = 0) and (eoWait in Options) then
begin
GetExitCodeProcess(ShellExecuteInfo.hProcess, ExitCode);
while (ExitCode = STILL_ACTIVE) and
(not Application.Terminated) do
begin
sleep(50);
GetExitCodeProcess(ShellExecuteInfo.hProcess, ExitCode);
end;
Result := ExitCode;
end;
end;
To run an elevated, hidden process and wait for it to exit:
ExecuteFile(Self.Handle, 'Filename', 'Parameters', [eoHide, eoWait, eoElevate]);
Hope this helps
