Buenas,
the answer to the question:
Is it possible to launch an application deployed with ClickOnce with administrator permissions?
It has a very simple answer:
NOT
The solution is two paragraphs later, so you can save the following text. The correct way to define an application requires certain permissions is through a manifesto. In it, you can indicate everything that requires an application at run time. The step by step, is on MSDN and is described in:
- Step 6: Create and Embed an Application Manifest (UAC)
http://msdn.Microsoft.com/en-us/library/bb756929.aspx http://msdn.Microsoft.com/en-us/library/bb756929.aspx
The problem is that if we have an application that then we deploy with ClickOnce, we apply this change in the manifest, and then try to compile we find a beautiful
Error 1 ClickOnce does not support the request execution level ‘requireAdministrator’.
And now? as one of the solutions comes from the hand of this post , where what is being done is basically to check if the application is launched with ADMIN and otherwise permits, launch the application again with the appropriate permissions.
I have created a small class that in addition to applying this process displays a message warning that the application will be launched again.
1: public class RunAsAdministrator
2: {
3: public bool IsRunAsAdministrator()
4: {
5: var windowsIdentity = WindowsIdentity.GetCurrent();
6: var windowsPrincipal = new WindowsPrincipal(windowsIdentity);
7: return windowsPrincipal.IsInRole(WindowsBuiltInRole.Administrator);
8: }
9:
10: public static void ValidateAdministratorModeAndRestart(bool displayMessage)
11: {
12:
13: var runAsAdministrator = new RunAsAdministrator();
14: if (runAsAdministrator.IsRunAsAdministrator()) return;
15:
16:
17: if (displayMessage)
18: {
19: var fi = FileVersionInfo.GetVersionInfo(Assembly.GetExecutingAssembly().Location);
20: string productName = fi.FileDescription;
21: MessageBox.Show(string.Format("{0} will launch itself with admin privileges", productName));
22: }
23:
24: var processInfo = new ProcessStartInfo(Assembly.GetExecutingAssembly().CodeBase)
25: {
26: UseShellExecute = true,
27: Verb = "runas"
28: };
29: try
30: {
31: Process.Start(processInfo);
32: }
33: catch (Exception)
34: {
35: MessageBox.Show("Sorry, this application must be run as Administrator.");
36: }
37: Application.Current.Shutdown();
38: }
39: }
In my case it was enough and with some exceptions that occur to me from memory, I think it may be enough
