Questions that start "what is the best ..." only have one valid answer: it depends. 
Are you planning to use an existing toolkit or framework? That will most likely dictate which language(s) you can use.
Have you decided whether this will be a traditional application, a mobile "app", or a web application? The choice of language(s) will be affected by this decision.
In general, go with the language you and your team are most familiar with, as long as it supports the type of application you want to develop.

On my decision, C++ is a mind-blowing programming tongue for an item build. It has multi-dimensional focal points. It is the most 'open' lingo, in any occasion as I might want to think. It's Dissent Arranged thoughts of composing PC programs is mind-boggling. It may show up fairly questionable if you are a student anyway it is a magnificent choice if you really need to wind up an item originator, site or application analyzer or in case you needs to make an application in solitude. This will assemble your knowledge about programming and what's more about the system and its diverse setups.
You can in like manner consider learning Android Studio(only after you learned C++) if you are possessed with Android stage and needs to diagram an application for Android.

As mentioned by other users you can use any language of your choice.
But keep in mind that ERPs are very complex system which you cannot build over one night. It takes long time. So it will be beneficial if you can leverage the built in features of some framework. Becuse the framework take care of most of the things. It separates the user, business logic and database. From that perspective Java (J2EE) is a good choice. I use Oracle ADF to build ERP along with PL SQL and JavaScript.

IMHO the most important and enduring language will be the one embedded natively inside your database of choice.
SQL and it's many add-ons and extensions are the core foundation of an ERP system (which over it's lifetime will probably be interfacing with different external clients written in several other front-end languages).
Model your business rules tight in the tables with triggers and stored procedures handling the standards like cascading updates and deletes, and all the non-standard data transformations handled by your database code, enforcing the business rules of your Enterprise at the core.
SQLServer, PostGre, MySQL, SQLite all are good options

I had to download Visual Studio into my D: drive because not enough room on C:. Now I can't launch it. How do I launch Visual Studio from my D: drive?

This might seem kinda off topic but I'm very concerned about this. I'm storing serialized objects in binary files as a data to load, there will be a lot of these files and I'm afraid that it might get corrupt because I want these files for a very looong time.
After reading this I have some more questions
Why, or How, do Files Become Corrupt? - Ask Leo![^]
1. There is no way I can prevent it?
2. If you don't use/interact a file there is a high chance of getting it corrupted?
3. Will the file get corrupted depending on its weight  like if its 1 gb or more?
4. What is the best way to store/keep my data clean for long time usage?
5. I know there is a huge chance of files getting corrupted if a windows crash occurs while I'm saving it. But what about like after the file is saved and if a windows crash occurs? will the file still corrupt?
PS: My english sucks, hope you had a fun time reading it!

Hello, I hope I'm posting in a place that is ok with discussion and not just question/answer. I know my question will receive some opinionated responses but not necessarily and regardless, it is something I really would like to ask people who are already working in the field.
I got into a developer's position a few years ago and it has been quite stressful for me. I feel I'm an intelligent person, I like technology, video games, programming etc. I have a passion for programming although sometimes I find it fading but I try to remain optimistic.
When I was interviewed for this position I made no effort to oversell myself. I was very upfront and honest about what I knew and didn't know. I provided code examples of what I had worked on and took a test that was assigned to me all before being hired. The position was supposed to be more of an entry level position.
At first I was really excited. So happy to finally be a developer. I wanted to learn as much as I could. I didn't necessarily want to stay with the company but I was happy to have got the position and wanted to learn all I could while I was here.
Problems soon arose and it's from these problems that I'm trying to get some insight into the industry to see what the job life is like for programmers outside of my little world/company.
The company I work for is a fortune 500 company, they are huge, all over the place, international, they're everywhere and you know them I promise, I prefer not to say though for privacy reasons. That being said, I was happy to get into this "entry level" programming position in this huge company cause I knew it would be a great learning experience.
I soon found out that I was being relied upon quite heavily and with very little guidance. My position, although I'm required to be in an office location, is virtual. Meaning, every programmer is at a different location, including my supervisors and management, and some (especially management) work from home.
One of my pet peeves is that, although I have a company laptop, and there's little to no collaboration taking place, I can't work from home myself, I have to carry my laptop with me and plug it in at the office I work at. While this irritates me alot, I can totally cope with this if the rest were ok.
My biggest gripe is the lack of collaboration, guidance, communication, and give a *@!$. I am given projects, with little to no background information, most the time via email, and that is it. I am told to ask questions if I have any. The majority of the time, my entire time spent here is one big question.
I'm trying to figure out, is this how it is where everyone works? Is it normal to hire entry level programmers, provide them with little to no guidance/training, and just assign them tasks to see if they'll still have their hair by the time it's all said and done?
This is something I'm really honestly curious about. I've been doing this for about 3 years now. I've learned things and manage to complete all of my projects on time but it's the process and the way things are managed that drive me nuts.
There are also long periods of time where I won't be assigned anything. I'm virtual so I come into an office that has nothing to do with me and sit. Sitting and waiting has been a large majority of my duties. My work life is a bit of a roller coaster. There's a very slow incline and then I'll get a project with no information or guidance and then it's a steep drop till I reach the end...
Half the time I feel it's just me, the rest I feel that it's just this place. That is why I'm on here to get an idea of what a programmer's daily job life is like.
Do you often find yourself with no resources or feel like you're kind of just there lol... I laugh but this has been the strangest and not so funny situation I have ever been in.
I also find patterns among people, ways of thinking among management. Things seem to be severely lacking. My idea is that the grass is greener on the other side but I'd like to hear from you all to see if that truly is the case or if I just need to suck it up and enjoy it somehow.
To give you an example, I was given a C# project recently, as I have many times in the past. I'm fine programming and figuring stuff out, I enjoy it, but there are times you just want to ask someone a question.
The person that was working on this C# project is no longer with us and I just found out I'm pretty much the only one that has any experience at all with C#... So me, an entry level programmer that had hoped this position would be a great learning experience is now more of a dreaded daily nightmare...
I do my best to accept and deal with the situations at hand and try not to panic but it can be hard at times. My thing is, why does it have to be like this and is it like this everywhere?
I'm not a dumb person, all I need half the time are some simple questions answered but I can't rely at all on the group I work for and it seems like they simply expect me to be Albert Einstein or something.
Then there's the guilt I feel for not knowing or feeling like I can't complete a task that gets assigned to me and fear of failure... It's just ridiculous.
Just to elaborate on the sitting and waiting. There are times I'll be assigned something, complete it, and I don't hear from anyone about anything for days or weeks. This feels like a giant waste of my time and I know it is.
Sometimes I won't be assigned anything at all so I'll email my supervisor and just say "Hey if I can help with anything let me know" and I may or may not hear back for who knows how long. I kind of stopped doing this though because now, I kind of enjoy not having anything to work on cause it tends to be stressful when I do.
My next steps are dealing with this a bit longer and spending my free time doing some coding of my own, brushing up my skills, and finding a new job. This is another reason why I ask this question because I want to hear what I may be getting myself into.
If you've read all of this thank you and if you have anything to share please do.

First of all, I know it's a bit late, but welcome to the community. Know that your experience is not unique, is not even rare, but is generally par for the course. There are very serious pluses and minuses to being a dev, but let's talk about something else first: soft skills.
By and large developers tend to regard logic, efficiency, and technical ability as positive traits. This is not the case with people in the lion's share of other disciplines, and over time this leads to many devs being a bit more reclusive and less invested in the work of others; to the point where the caginess of programmers is pretty much a stereotype. Now, this caginess is not reserved for "outsiders", but rather anyone that does not meet each individual's bar for competence. This is the first primary contributing factor in the response that you've received, and don't be so self-centered as to assume that how people interact with you has everything (or anything) to do with you.
Now to where my own caginess might show: the things that you're complaining about are actually the job. Yeah, writing code is nice and all, but it's not the hard part of the job. Expressing yourself in code is a baseline, and every knowledge domain is different, so each new project will, largely, throw you right back into a pit of not knowing what's going on, not having a foundation in the subject matter, or generally not being sure of where to immediately go. This is entirely the reason we have an SDLC and why the things that may not have seemed terribly important in school are very important in practice.
You're also not expected to know everything, despite how it might feel at the moment, but you are expected to be able to figure things out that are in the knowledge domain of the company that you work for. You are expected to understand some patterns and practices when it comes specifically to engineering, but that's part of the trade. Never, ever, play "smart" when you're lost: questions are invaluable, ask them!
Learn to provide realistic estimates (the Scotty rule can help...) so that you don't always feel under the gun. Sharpen your research skills; Google is the ultimate expression of RTFM, and being able to read up on APIs or even check source on GitHub is a gigantic leg up. Utilize it without shame or fear.
When you don't have a current project, experiment. Play with a language or technology. Look for holes that you can plug. Make a space for yourself within the organization.

I'm unsure if I understood everything correctly. Is the following correct:
1. A Text encrypted with PRIVATE_KEY can be decrypted only(?) with PUBLIC_KEY
2. A Text encrypted with PUBLIC_KEY can be decrypted only with PRIVATE_KEY
Thank you very much for help and sorry if the question is stupid...

Close. Depending on your use case, you will have a PUBLIC ENCRYPT and a PUBLIC DECRYPT key. These are completely separate key sets that are associated with PRIVATE DECRYPT and PRIVATE ENCRYPT keys respectively.
Generally, you encrypt a hash with your PRIVATE ENCRYPT key to provide a digital signature, as it can be verified using your PUBLIC DECRYPT key. For actual message encryption, your PUBLIC ENCRYPT key will be used to encrypt it so that only your PRIVATE DECRYPT key can decrypt it.
With the PKI model, you can freely hand out your public keys (or they are stored in a central repository, such as on a domain) while your private keys needs to be properly secured to prevent compromise.

Hi !
The logical to remember with Public , Private Keys is about 2 crypting channels.
From both sides, 2 differents Keys will operate.
Like all cryptos, one can be reverse , not the other.
But the A to B, B to A must transmit all datas, and verify them.
Look at what can be switch : ( What is surrounding ? )
Computer A , Computer B
Keys A , Key B
Private function crypto
Public function crypto
Clock from A(all in) , Clock from B(all in)
checksum A , checksum B
while you ensure no errors of receiver .
The work is all done.
It's "pair" working.

I got -50 points around for this article Improve-the-Way-of-Writing-Functions . But as per the code project documents when author gives down vote author should give proper reason. Please help me if I am wrong.

This has nothing to do with this forum. Also, giving reasons has been debated many times and it's not going to happen because the reasons would either be rubbish or people would be put off voting.

Also disclosing reasons would invite privacy issues for the #voter

If a solved code is correct is it reevaluated ?

People downvote for all sorts of reasons, it's annoying when your answer is given a bad rating just because the poster didn't understand\try the code, or whatever, but overall those votes are countered by the better votes you get.
I looked at the last few answers you gave though, and I guess a reason you're getting so many low grades is because you're not properly formatting the code in your answers so it is hard for people to follow. Learn how to use the "pre" tags, or paste your code into the solution box so you get a pop-up asking how you want the pasted code to be formatted and select the appropriate option.
Do this
$(document).ready(function () {
var select = $("#<%=lblMultiSelect.ClientID%>");
var senddata = select.val();
var txt = $("#<%=listBoxValue.ClientID%>");
select.change(function (e) {
$.ajax({
type: "POST",
url: "CS.aspx/GetCurrentTime",
data: '{name: "' + senddata + '" }',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: OnSuccess,
failure: function(response) {
alert(response.d);
}
});
});
});
function OnSuccess(response) {
$.each(response, function (i, el) {
});
}
not this
$(document).ready(function () {
var select = $("#<%=lblMultiSelect.ClientID%>");
var senddata = select.val();
var txt = $("#<%=listBoxValue.ClientID%>"); //<
