I'm doing traffic simulator, but I don't want it to be static map with moving cars, I want it to have methods to generate the roads with intersection (for now I have few simplifications like the roads are straight vertical or horizontal lanes, for now there is also no roundabouts and priority on road - on each intersection are the traffic lights). I started to code it, but quickly I noticed, that easier way will be first do the graphic (I need just an easy one) and then deal with things like …

I am doing a team project with some people that prefer Linux and some people prefer Windows. We are also not allowed to share code for security reasons. One thing the Windows people love to whine about is a way to hold the window open. So the way they usually solve the problem is with: #include <conio.h> getch(); This creates a problem for the Linux users since we do not have that library. I have been looking for ways to solve this problem and I really like this idea. https://www.dreamincode.net/forums/topic/30581-holding-the-execution-window-open/page__st__30__p__575874&#entry575874 #include <stdlib.h> //For system commands //Detect and define which command …

Hello all, I am relatively new to Visual Basic and have managed to muttle my way through creating a 2013 Word document that has some ActiveX controls.

The email is then stored in flatfile database (.txt) The person then gets an auto-reply email with a link to confirm their email address. Upon confirming after clicking the link, their email address is saved to a new file confirmed_emails.txt for example. Is this possible without the use of a SQL/similar datase, and how can I achieve this? Note: SQL or other database option, …

Hello Daniweb Community, I have been talking on a couple [Facebook](http://www.facebook.com) groups such as sale pages where you post your own stuff for people to buy. Most groups like this have rules about bumping like once per day, every 12 hours etc... So it got to the point where it became annoying to have to bump my posts every so oftern so I managed to construct this script that'll do it automatically with the help of a cronjob that can be set to bump at whatever time you like. So I have made a simple easy to use (ha may …

I am on the latest version of Windows 10, running with SWI-Prolog 7.6.4, and trying to get JPL (Java <->Prolog) running for a school project.

I've just realized as I write this that maybe I need to reboot. I will try that after posting …

Hello! I am interested in the issue of protecting the code from hacking. Do you protect your code from decompiling and hacking? Why did the question arise? I worked in a team that developed games for Android. They all used obfuscators! So almost no one could hack their application. Now I am interested in the topic of code protection. I looked at the existing topics, they are slightly outdated (8-10 years ago were relevant). Use / not use obfuscator? Which to choose?
