I have a console app that (in certain situations) does not work correctly when UAC is enabled. As such, I'd like to print out a warning (and, if possible, trigger an UAC authorization screen) if UAC is detected as activated. What is the code to do so?

If possible, I'd prefer code in C or C++ for the following functions:

/* returns 1 if UAC is enabled, 0 if disabled or the OS is a non-Vista  one */

int isUACEnabled()


/* triggers an UAC authorization dialogue, granting full access for the rest of the program's operation. Returns success or failure. */

int AskUAC()

I'm sorry if AskUAC() asks for something incompatible with how Vista works, I'm not any familiar with that.

I tried to search for UAC and "User Account Control", but the first search is disabled and the second didn't return anything relevant.

Many thanks for any answer.

You need to use the registry to check and see if UAC is enabled. The value is 'EnableLUA' under 'HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System'

If its a '1' then its enabled, else its disabled. If the value doesn't exist, its not running vista.
