Out of private / experimental interest, I've been writing low-level cross-platform UI functionality with .NET Standard 2.0, and implemented creating a window
on Windows (via WinAPI P/Invoke) and
on Linux with an X11 server (via Xlib/libX11 P/Invoke).
So far I can run the X11 code nicely on Linux with MonoDevelop, but I thought it would be useful to develop for an X server running on Windows (like Cygwin/X or Xming X Server).
For that however, I require an Xlib Windows DLL which I can P/Invoke to, as .NET Core only supports Windows DLLs on Windows platforms (AFAIK).
Before I get myself into the trouble of "porting" the Xlib source to compile with MSVC++, I wonder if there is any project available which already creates an Xlib Windows DLL, or if any such compiled DLL is readily available somewhere?
I found a X11.dll as part of some commercial X server from the mid-1990s for Windows NT, except I don't remember which X server product however. I do know, however, that it'll do what you want.
It's 32-bit, but you can use this DLL: https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/segin-utils/X11.dll
I used it to produce a 32-bit Windows build of a window manager I had worked on years ago: https://github.com/segin/matwm2
Build: https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/segin-utils/matwm2.exe
If I can figure out how to upload release artifacts to GitHub, I'll probably archive these files there.

I started developing Delphi, but I do not know how to use Delphi in Linux.
You can't use Delphi itself in Linux directly, as the Delphi IDE and compilers are all Windows-only executables. So, to run Delphi on a Linux system, you would have to run it inside of a Windows-based virtual machine running on Linux.
However, Delphi 10.2 Tokyo and later include a compiler that can create executables that run natively on Linux.
Unfortantley you cannot run Delphi in Linux. But there is an amazing alternative. It is called Lazarus! It will run on Linux, Mac or Windows. Get it at https://www.lazarus-ide.org/
I am actually surprised Lazarus isn't one of the most popular desktop development tools. If you find it useful and you are capable you should also contibute to the project. It has come a long ways in the past 10 years and with it I don't think you will need to even consider running Delphi on Linux. Lazarus with FreePascal is sufficient!
Also maXbox runs on Linux with a lot of scripts and also python for delphi.
we need Wine to run the scripting engine on debian linux.
maXbox is a script tool engine, compiler and source lib all in one exe to design and code your scripts in a shellbook! Pure Code for Object Scripting. Principle is simplicity and reduce to the max.
The App is “out of the box” (self containment) and needs no installation nor registration.

I've seen several tutorials on how to compile C++ applications for Windows on a linux system, however, I have failed to find a way to use Windows specific headers (i.e Windows.h) in my C++ program to compile for Windows (.exe/.dll). I was wondering if anyone knew how I can compile Visual C++ programs on Linux that use Windows OS Specific headers/functions (just compile). Thanks!
You can't. Windows system headers, e.g. windows.h reference OS specific APIs that are not known to Linux. Only Microsoft's compiler can create Windows format objects and executables and it doesn't run on Linux.
You can create cross-platform applications consisting of common code that will build and run on Windows and Linux. But the only way to use platform specific APIs in such an application, e.g. GUI, is to #define sections in/out according to the build environment.
Background:
Im using QT and have visual studio 2012 as my IDE (used the QT plugin for visual studio).
And finally the whole project is done. However due to my .NET background I have no experience when it comes to deploying my project so it can be run on Linux.
Question:
Anyone knowing how to deploy a QT project made in visual studio to linux?
You should install Linux and prepare a Qt development environment on it.You can then copy your project there, compile it and see the results in the real environment. This way you can cope with the minor differences when porting from one OS to another easily.
So don't think of cross compiling your app for Linux on Windows. From a complexity point of view, I think setting up a Linux machine (VM or not) and the necessary environment for Qt is a whole lot simpler than cross compiling bug hunting afterwards. After all you will need a real target environment to finally test your application.
Before you can deploy something you have to compile it for that platform, and here you have two main choiches: either you cross-compile which means you compile it on windows using a set of tools so that your software is built to run on a linux, or you get a linux machine, you copy your entire project over and let Qt for linux do the magic.
Once you have your working binary compiled on linux or for linux then you start thnking about deployoment.
If you really want to be fully linux-compatible and "linux-ally correct" you should distribute your source-code precooked using some tools like "automake" that will make it possible to linux users to compile it on any linux version.
If you do not want to release your source code, you technically can distribute binaries without source code (not sure if you will be ok with licenses) but you have to be aware that there is no standard in linux for distributing binary packages, there are at least 2 main package building standards that are the ubuntu/debian style and red hat (and friends) style.
You are going to find plenty of documentation about all this stuff from cross-compile to automake and of course building debian packages and building red hat rpm packages.
Is it possible to run VB.NET in Linux?
I have written code in VB.NET and compiled it as well using Visual Studio in Windows.
Can the same code be written (and compiled) on Linux as well?
If yes, then which software do I need to install on Linux?
Is the Linux alternative of VB.NET freeware?
You can run Visual Basic, VB.NET, C# code and applications on Linux.
The most popular .NET IDE is Visual Studio (now in version 2019) that runs in Windows and macOS. A good alternative for Linux users is Visual Studio Code (runs on Linux, Windows and Mac).
You can compile and run VB.NET code and applications (part of .NET framework, consider the successor of Visual Basic, with several language differences from Visual Basic 6.0). A subset of .NET is .NET Core that can be installed on
Red Hat Linux,
Ubuntu,
Linux Mint,
Debian,
Fedora,
CentOS,
Oracle Linux
and openSUSE Linux distributions.
Setup details are on https://www.microsoft.com/net/core.
You can also use Mono, a free and open-source project led by Xamarin (a subsidiary of Microsoft) and the .NET Foundation. The project focus is to support an ECMA standard-compliant .NET Framework-compatible set of tools (including a C# compiler and a Common Language Runtime).
Mono can be installed on
Ubuntu,
Debian,
Raspbian (used in Raspberry Pi)
and CentOS Linux distributions.
You can run most Windows applications (created with VB, VB.NET or with other tools) using Wine that supports the Windows API on Linux.
** About Visual Basic (not VB.NET, due to the original question) **
Note that the last version of visual basic is 6.0, released in 1998, declared legacy during 2008 and supported on Windows XP, Windows Vista, Windows Server 2008 including R2, Windows 7, Windows Server 2012, and Windows 8.x. There are also other basic flavors (like QuickBASIC, Gambas or others).
The support end dates for Visual Basic 6.0 are:
The Visual Basic 6.0 IDE [Integrated Development Environment]:
supported ended on April 8, 2008.
Visual Basic 6.0 Runtime the base libraries and execution engine used to run Visual Basic 6.0 applications: support ended on April 8, 2014.
Visual Basic 6.0 Runtime Extended Files: support ended on April 8, 2014.
You could have a look at the Mono VisualBasic.Net support, or maybe go and check out the Gambas project.
You won't find a fully compatible solution.
There are a few, like SimpleBasic, GnomeBasic and XBasic. None of them are fully compatible with Visual Basic.
The above answer was accepted eons ago, but is horribly outdated, since more recently, there's also .NET Core. This will run the actual VB.NET language, but it will not use Windows Forms controls and features powering most real VB.NET applications. .NET Core 3 does support some variation of Windows Forms, but only on Windows.
Please check Pedro Polonia's excellent answer that contains all the details that mine misses.
Mono is a really interesting project. You can run applications on Linux.
Is not fully compatible, but they are working on that.
Take a look in this site Working with Mono
VB on linux is posible using vb2005.
First install wine.
run in the terminal winetricks dotnet20 dotnet40
download the installer and run it
(wine Downloads/yourinstaller.exe)
execute wine WINEPREFIX=~/yourprefix WINEARCH='win32' wine yourprefix/drive_c/Program\ Files/Microsoft\ Visual\ Studio\ 8/Common7/IDE/vbexpress.exe
Gambas Basic is actively developed and works good. Here you can find a small tutorial for programming a calculator:

The Java countdown is now running :-)
For those looking for an alternative to Visual-Basic and Visual-Studio with cross-platform support, B4J (Basic For Java) is a good choice too. It's free, kind-of\semi "open-sourced" and really user friendly especially for those coming from VS.
Hi I am new to android NDK Devlopment.I downloaded Android NDK 4 for windows.I read through the docs.But i am not clear with it.
First thing is that,I want to develop the native file which may be c 0r c++.I think Using Cygwin will come to play.I dont have any idea or how to use cygwin .From the Docs i just read Cygwin is required for Windows platform.Apart from it ,i dont have any knowledge about it.
Not yet started with NDK Concepts.Help Required
Cygwin is a way to make Windows support some linux functionality. If you install cygwin on your windows machine you'd be able to run some linux software on windows (you'd have to recompile it especially for cygwin though). You can find it and more information about it here. There's also a good explanation at the wiki page here.
If the Android NDK needs it I suppose the Android NDK needs some linux functionality or tools to work properly. The other option might be to install Linux on a machine and run the Android NDK on there, it might be better since I assume Linux is the native environment for Android NDK development.
Since you're saying that you're a bit unclear about the NDK, you should probably be aware that as far as I understand you can not build a whole Android app using it, you can only develop bits of it, you will still need to develop at least part of the app to run on top of the Dalvik virtual machine, which, as far as I know, means that you'll have to write that bit in Java. In general I think that you should develop Android apps only in Java unless there is a specific reason to build certain parts of it using the NDK.
From wiki:
Cygwin (pronounced /ˈsɪɡwɪn/,[2] SIG-win) is a Unix-like environment and command-line interface for Microsoft Windows. Cygwin provides native integration of Windows-based applications, data, and other system resources with applications, software tools, and data of the Unix-like environment. Thus it is possible to launch Windows applications from the Cygwin environment, as well as to use Cygwin tools and applications within the Windows operating context.
Cygwin consists of two parts: a Dynamic-link library (DLL) as an API compatibility layer providing a substantial part of the POSIX API functionality, and an extensive collection of software tools and applications that provide a Unix-like look and feel.
So, Cygwin is a set of tools which allows you to emulate a unix-like (or linux) environment on your windows machines.
The NDK is the Android Native Development Kit. It allows you to write parts of your application in native code (C/C++) and integrate them into your application. Your application still runs under the Dalvik VM but it can load shared objects creating using a cross compiler. The NDK contains all the necessary tools and build scripts to generate native code binaries. It's an advanced concept and one you should probably wait on until you fully understand the architecture.
The reason why it requires Cygwin (or some flavor of linux) is because it uses GnuMake and other linux tools such as awk or Nawk. These tools are not available (or are really hard to use) on windows platforms, hence the need for at least Cygwin (though I would advise you do yourself a favor and just install linux).
