Confidence that I have solved all strange errors here, I come back with some issue generated by a legacy C code for linux, code that I intend to use it in a MFC app in windows OS.
Ok. I have a simple code:
int nRespond = _open(device, 020);
UINT err = ::GetLastError();
where devide is const char* and has value C (or D:, or E: )
The nRespond is -1 and err has value 5, which is mean Access is denied. What could be the problem here ? I ran the test app as administrator mode (ran from VS2017 as admin mode).
The problem appears to be that you are expecting Linux code to work on Windows. The _open function opens a file - on unix systems you can open directories and devices as files, but not on Windows.
If you're lucky the code is actually expecting a normal file and you just passed in a device letter by mistake. Otherwise you will have to port the code, replacing the Linux system functions with code that does the same thing on Windows.
You cannot run Linux code on Windows without adjusting it for the differences. Windows does not let you address raw devices in the same way that Linux does. And in fact doing so is very dangerous as you could destroy your entire system.
Good idea. I have used CreateFileA, and I get rid of that "access denied". But there a thing that I had afraid: the original code, with _open returned int, and CreateFileA return HANDLE ... casting HANDLE to int is OK ? I guess not ...
I need help with backtracking question.
In an election, five parties won and got
In order to rule, a coalition of More than 60 must be negotiated. But we have restrictions:
A does not sit with D
C does not sit with E
A B C D E
A. 1 1 1 0. 1
B. 1 1. 1 1. 1
C. 1 1. 1 1. 0
D 0 1. 1 1. 1
E. 1. 1. 0. 1. 1
The function should return the number of possible coalitions.. Which is 3.
As soon as the coalition is formed, no need to add more parties.
A + E + B is not valid
I don't see why not. Above the condition was stated that
a coalition of More than 60 must be negotiated
which means neither A+E nor A+B or B+E would be enough - all three are needed to get more than 60.
As for your program, if you don't know what backtracking means, look up recursion and backtracking. There's nothing difficult about coding these concepts in C. If you do know what it means, write a program and, if at any point you're stuck, show the code you're stuck with.
We don't write full programs for other people on request. If it's homework, we'd do you a disfavor by destroying a chance for you to learn. If it's work, you'd get paid, and you can't expect from others to do that work for you without payment. If it's a contest, it's part of the contest to find out how to write the program - if others do it for you it tells nothing about your skills, and it would be unfair to the other contestants.
GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them. (Fran Poretto)
currently I am comparing the MeshCommander and the Intel Manageability Commander for configuring AMT Version 12.
With the MeshCommander I was able to configure AMT Version 12 for a TLS connection.
But I found no way to do the same with the Intel Manageability Commander.
1. Where are the setting in the Intel Manageability Commander for TLS configuration?
2. How can I configure TLS with Intel Manageability Commander?
Regards and thanks in advance for helpful answers
