Question Background:
I am calling a batch file to run a specified dll against the MSTest.exe through the use of a Process object.
The code:
I want to ensure that at all times this process is run with elevated administrator permissions.
I do this currently by setting the process verb property to runas, as shown:
try
{
_process.StartInfo.Verb = "runas";
_process.StartInfo.CreateNoWindow = true;
_process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
_process.StartInfo.Arguments = testLocation + " " + testDll;
_process.StartInfo.FileName = batchFileLocation;
_process.Start();
_process.WaitForExit();
}
catch (Exception ex)
{
throw ex;
}
The issue:
This runs as expected but the User Account Control (UAC) prompt asks to confirm that I wish the process to run the .exe.
As this code is part of an an automated process I cannot have any human input to click the 'Yes' button on the prompt, how can I disable the UAC prompt?
You cannot bypass the UAC prompt.
Ask yourself: What would you do if you were doing this on Windows XP?
Imagine you were running on a operating system that did not have UAC. What would your dll do then? You no longer have the convenience of UAC, and instead you are always running as a standard user. What would your test regime do then?
If you don't like the UAC dialog you can turn it off. But you'll be in a no better situation, because now you're just like you were on Windows XP: a standard user and no easy way to get out of it.
The real solution is to fix what your dll is doing that is protected. For example, if this is a COM dll, and the self-registration is failing because you are trying to write to HKLM, then you need to
If your dll is crashing because you are trying to write to C:\Program Files, then you need to change the security settings on C:\Program Files to give yourself access.
The solution is to fix what is failing.
