How windows 10 writed? - windows

Hi I know C++ and I searched and found that windows 10 written in C/C++ & Assembly but I have no idea how windows 10 works, Is it because I don't know the assembly? Do I understand when I learn Assembly?

If you learn assembly, it will help you to better understand the concept of operating system and communicate directly with hardware, but it is not your definitive solution. However, companies like Microsoft usually have their products closed source and you can not easily understand that Exactly which section is written in what language, and finally, if you are thinking of writing an operating system, it is difficult for you as a single person, I suggest you form a team

Guessing the programming language used for a software [duplicate]

This question already has answers here:
Find Programming Language Used
(14 answers)
Closed 2 years ago.
The question is simple from a programmer's point of view. How do you know which language / libraries has been used to develop a specific software product.
Say you have average knowledge of computing who can understand by checking product file (.exe, .dll, etc) names / versions that this piece of software has been written using Visual C++ / .Net / QT , etc.
Any solid ideas by which one can know about a programs's programming language?

Thanks for the link. It just opened my mind.
I do use ProcessExplorer, ProcessMonitor.
For better investigation even one can use Spy++ utility provided with Visual studio. PEiD can be useful, but these days application program comes with packed method so PEiD is unabled to digg through those files.
So I would strongly suggest anyone who is or will be looking for these things follow the below steps.
Investigate program files - .exe, .dll, .ocx
Check loaded modules into program memory by ProcessExplorer or similar
Use Spy++ to get the window class, try to search that on google

Porting a multi-threading Delphi application to Mac: what are my choices?

I need to port an application (written in XE2) to Mac.
My application is split into a simple UI executable (single-threaded) and an invisible engine (which heavily relies on OmniThreadLibrary 3.02 and Cromis DirectoryWatch)
Both EXEs communicate via Cromis.IPC
This is to say that I mainly have issues with these 3 components (OmniThreadLibrary, Cromis IPC & DirectoryWatch)
My focus right now is the Engine, which has most of the code.
My question is: Is there something similar to OmniThreadLibrary, Cromis DirectoryWatch & Cromis.IPC for Mac? (Whether with lazarus or XE2 with Mac as a target compiler)
The answer will help me a lot in deciding whether I should use Delphi XE2 or Lazarus (an IDE which I'm not familiar at all with) and see what's the best long term approach to offer/support both Windows & Mac with the minimum headaches
I am answering the part of your question dealing with compiler /IDE. I've used Lazarus and I must say that it won't take you too long to get up to speed (except for your exact requirements). Lazarus is getting more and more professional; a number of the developers are professional Delphi / XE2 coders by day. I think since you want to make your application available on Mac, you are going to have some work cut out anyway. But, it you decide to use Lazarus, you can for the most part build applications for Linux, Mac, and Windows without much effort ... most things just build right for each of the platforms from the same mostly unmodified source. Of course, as you say, your code heavily leans on OTL With OTL being a windows only library, I think you are going to have your work cut out for you. (read ... you might have to write an equivalent library yourself, or have someone do it for you) As for Chromis Directory watch, I haven't found anything yet.
I hope this helps a bit. CHEERS
This Lazarus tutorial shows that threading functionality built in. I am unaware of an equivalent library for what you are searching for. CHEERS

The possibility of creating an OS independent GUI software

Greetings , I have a few questions that need experts' help to demystify it.
Question:
1.)Can a GUI be created without using any framework or API like GDI and DirectX??
2.)How microsoft develop the GUI environment for his OS??
3.)Is it possible that I could get knowledge about creating a GUI which run during booting without relying on an OS??Does it require any special tools which we do not own at home but is available in microsoft??
4.)Any book recommended for me to know more about GUI development of OS like windows and linux??
Thanks for spending time reading my question , your help is much appreciated
I'm not an expert on this field but to my knowledge:
Without considering your question #3, Yes, use a programming language (PL), but if you consider PL's as framework then NO, or even if it's possible, it is certainly not practical. Even Assembly (machine language) is a programming language.
To help understand the answer to this question, I suggest you read what an operating system is and how it is created. MS Windows (depending on the version) is written using PL: C, C++, C#, and Assembly. They used what we consider now as "low-level" programming to create their GUI's.
I find this question conflicting, I believe you need an OS to run a GUI. Because an operating system is responsible for connecting your hardware together (e.g. where to output the display, where to get the inputs like keyboard and mouse, etc). If you want, create an OS yourself but again, I find this very impractical. What you can do is start learning how to create GUI from Linux or even build your own minimalistic OS from Linux from Scratch. I recommended Linux because it's free and mature (relatively stable, has tons of documentation and internet references)!
I can't recommend any specific book, but types of book: Programming Languages and Operating Systems. Also, you can find all the resources you need on the internet. You just need to know exactly what questions you are looking an answer for.
But if you simply want to create a GUI that can run on most Operating Systems, this has been the aim of Java. Java uses a virtual machine to do this. Of course there are other options too, you can research about it. If it's already available that suits your needs and it's legally free, use it. It will save you a lot of effort. :)

Completely Stand-alone gui-application

Which programming language and tools can i use, to develope a complete stand-alone gui-application? This application will be burned on a cd and should run on every windows-pc without any installations.
Questions like what your application and what your capabilities are need to be considered.
There are many solutions to your problem. From 'Visual Studio Ultimate' to a HTML file which contains javascript.
Win32 API.. a similar question was asked today...
Use Visual Studio (you can use express edition) and build whatever you like.
This is the most powerful language, yet development time is very very slow, but the results are:
a. independent.
b. if you a good programmer - small and fast.
one thing - you got to know what you're doing when programming win32...
one Petzold book will get you where you want to go.
similar question
Well, if you really have the time and don't need to deploy on 16-bit Windows, you could always write in Win32 assembly -see MASM32 and Iczelion's Win32 tutorials. There's even a IDE for Win32 ASM -WinAsm Studio :)
The only dependencies you'll need are the Windows system DLLs which are already there on every Win32 system.
However, if you need to build something quick, something like Visual Basic 6 will do nicely - it only needs the VB6 runtime by default (1 ~ 2 MB) and that definitely fits into a CD together with your VB6 EXE.
I'd go for C++ with MFC. Reasonable development times and with static linking it could all be one standalone exe file.
If you are just looking to make one of those interactive splash screens, might want to look into Demoshield. I know its old and not supported any longer, but can be of real use for something great looking.

You can find copies of it free by google-ing it. Don't think the company is around any longer so not sure if this is legit or not.
But not the right choice if you need to do some serious programming stuff.
Delphi also may be a good choice.

What resources do I need to write an emulated device driver?

In a nutshell, I want to write my own device driver for windows, so that I can emulate a piece of hardware. I know very little about writing device drivers for windows, but I have a very firm understanding of the C and C++ languages, and I know enough x86(_64) assembly to get around.
I'm not really sure how one would go about even compiling a device driver, or what is required to create one. I'm certainly not against coding the entire thing in assembly if that needs to be done, but does it?
I'd like to do this using Windows tools obviously, I'm planning on trying to put it together using a windows GCC compiler, but I've got access to Visual Studio if that's needed. Can someone point me at resources that would be helpful, like reference manuals, tutorials, specs?
Oh: My target OS here is Windows 7, 64bit, which if I understand should be the same as Windows Vista 64bit, but correct my wrongness if it exists.
Thanks.
Everything you need to build your driver (including the compiler) comes from the WDK. Everything you need to know what to write comes from Walter Oney's books. Be prepared for a rough ride.
