After trying serveral things to make it work, I could not so I figured I would ask here since the people here have been helpful in the past. Now I am not so sure how helpful this forum really is...

Well if you read it you can at least state that you don't understand what it says, so we don't have to go through all of it. When someone shows you how to do something right, and the very next time you do it wrong again, then we can only assume you did not read it.

If you still don't understand, you have to have it like this:

(Toggle Plain Text)

HANDLE hProcess = OpenProcess( PROCESS_QUERY_INFORMATION | PROCESS_VM_READ | PROCESS_TERMINATE, FALSE, processID );

@Cache: I gave that link in the post two before yours.

The handle must have the PROCESS_TERMINATE access right. For more information, see Process Security and Access Rights.

Ah, I completely missed that part in the code... Its a bit hard to distinguish the bold from the rest in some instances with the italics. Thanks for the help Cache.

Well, at times its hard to understand everything you read when also trying to juggle 3 other tasks at the same time... Guess I should have read it at home instead of at work.

Bonus tip: get debug privs and you'll have a better chance of getting a handle to a process with the access rights you want. Use the function below in your app then check it's output. You should get less <unknowns>'s.

(Toggle Plain Text)

bool GetDebugPrivs( void )
{
	HANDLE hToken;
	LUID sedebugnameValue;
	TOKEN_PRIVILEGES tp;

	if ( OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken) )
	{
		if ( !LookupPrivilegeValue(NULL, SE_DEBUG_NAME, &sedebugnameValue) )
		{
			CloseHandle( hToken );
			return false;
		}
		
		tp.PrivilegeCount = 1;
		tp.Privileges[0].Luid = sedebugnameValue;
		tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;

		AdjustTokenPrivileges(hToken, FALSE, &tp, sizeof(tp), NULL, NULL);
		CloseHandle( hToken );
	}
	
	 return ( GetLastError() == ERROR_SUCCESS );
}

Cache, just give him the source to fkill or a codeproject article.

Thanks again for the help. I did try the debug privledges and that showed one process that used to be unknown. Not really useful for much now, but maybe in the future.

Thanks,

I've never heard of 'fkill' before, but yeah, that would have been a better idea. Interesting site too.

@badbasser98: On my machine your program only showed about 5 out of 20(ish) processes without debug privs. Plus, even if you only see 1 extra process then thats a 10% increase in accuracy over 10 processes. I'd say it's worth it.

on my work PC (where I do most of my programming) that program shows all but three of 46 processes without debug privs. Now that's down to two with the privs.
