I've need to add a function to my C# WPF application to fix up certain registry entries.
This would be done by calling regsvr32.exe /s mylib.dll. Now, this should be easy to do from what I see using the runas verb with a new Process object. (My dll does require admin rights due to some registry keys it writes to.)
But the problem is there are multiple DLLs, thus multiple invocations of regsvr32.exe, and it is not possible to put all the registrations into a single .dll. But were I to just runas multiple times, the user would get as many UAC dialogs as I start it... and I don't want that.
I want just a single dialog, and I really really want to avoid having a mystery extra fixer.exe file to have to do the launching instead. Now, I only know Windows Security stuff on a really basic level, but shouldn't it be possible to get an 'admin' token somehow (which gets me the UAC dialog) and use that to launch the different processes?
You can just use command line arguments, and shell to your own .exe running that process as an admin. When your application loads, check for those command line arguments...If they are there, register all of your dlls, then exit.
Or, you could write a batch file that registers all of the dlls, and shell to that with admin rights.
