How to detect if executable requires UAC elevation (C# pref)

Question

Hi, how can I detect if executable requires UAC elevation? So far I came to two ideas: picture recognition of executable's icon to check if UAC shield icon is on it and information from wikipedia: http://en.wikipedia.org/wiki/User_Account_Control

it is possible to programmatically detect if an executable will require elevation by using CreateProcess() and setting the dwCreationFlags parameter to CREATE_SUSPENDED. If elevation is required, then ERROR_ELEVATION_REQUIRED will be returned.[16] If elevation is not required, a success return code will be returned at which point you can use TerminateProcess() on the newly created, suspended process. This will not allow you to detect that an executable requires elevation if you are already executing in an elevated process.

Thanks

Answer 1

Why would you want to use picture recognition if it can be checked programmatically? You can use P/invoke to call CreateProcess with desired parameters.

Answer 2

The best way is to parse its PE format and then know whether its manifest file requires UAC.

Not sure how Kenny wrote the code, but it shows the possibility.
