How does a program ask for administrator privileges?
提问by Niyaz
I am developing an application using vb.net. For performing some tasks the application needs administrator privileges in the machine. How to ask for the privileges during the execution of the program?

You can edit the UAC Settings(in VB 2008) which is located in the Project Settings. Look for the line that says
您可以编辑位于项目设置中的UAC 设置（在 VB 2008 中）。寻找说的那一行
<requestedExecutionLevel level="asInvoker" uiAccess="false" />
<requestedExecutionLevel level="asInvoker" uiAccess="false" />
Change level="asInvoker" to
将 level="asInvoker" 更改为
level="asInvoker"(same access token as the parent process)level="requireAdministrator(require full administrator)level="highestAvailable"(highest privileges available to the current user)
level="asInvoker"（与父进程相同的访问令牌）level="requireAdministrator（需要完全管理员）level="highestAvailable"（当前用户可用的最高权限）

There are several articles on the Internet about developing elevated processes in Vista, but essentially elevation requests involve decorating .NET assemblies and WIN32 executables with elevation status in the application manifest file (may be embedded or side-by-side).
Internet 上有几篇关于在 Vista 中开发提升进程的文章，但本质上提升请求涉及在应用程序清单文件（可以嵌入或并行）中使用提升状态装饰 .NET 程序集和 WIN32 可执行文件。

I have not done this yet but I believe you go to (in VS 2008) Project Settings -> Application Tab and click on the "View UAC Settings" button. This opens up your app.manifest file. In there is a tag which I think holds the options you're looking for. Mine has some options commented out which should get you started:
我还没有这样做，但我相信你去（在 VS 2008 中）项目设置 -> 应用程序选项卡，然后单击“查看 UAC 设置”按钮。这将打开您的 app.manifest 文件。我认为有一个标签包含您正在寻找的选项。我的一些选项被注释掉了，应该让你开始：

IN VS 2015: Go to: Project -> (name of project) Properties... -> Application -> View Windows Settings and find in app.manifest (line 19): And change asInvoker to:
在 VS 2015 中：转到：项目 ->（项目名称）属性... -> 应用程序 -> 查看 Windows 设置并在 app.manifest（第 19 行）中找到：并将 asInvoker 更改为：
- "asInvoker" (same access token as the parent process)
- "requireAdministrator (require full administrator)
- "highestAvailable" (highest privileges available to the current user)
- “asInvoker”（与父进程相同的访问令牌）
- "requireAdministrator (需要完全管理员)
- “highestAvailable”（当前用户可用的最高权限）
