GUI Only By Using FPC - user-interface

I want to know how I can develop GUI applications(32 Bits) without using Delphi language(Object Pascsl), only by using FPC with Lazarus installed(Pascal). Thanks.

Use a widget set directly. Look at e.g. the examples in packages/gtk2 for unix, or the windows win32api usage demo. (demo\win32 in the FPC win32 installation)
But not using lazarus makes you lose platform independance, and a lot of ease.
Looking how lazarus does it, is still a possibility.
A second option is https://github.com/mse-org/mseide-msegui

You can also use FPC Qt4 Binding.

Take a look at built in LCL, and external fpGUI and mseGUI.

Using windows.pas with Lazarus on OS X

I was wondering if it's possible somehow to use windows.pas on OS X with Lazarus?
I need to use special library in my project, and one of key-files uses windows.pas :( Any ideas?
Windows.pas only works on Windows. You will have to edit the library to put an IFDEF around it in the uses clause, and then provide alternatives for any functionality that is then broken. Or contact the library author and see if there is already a non-Windows version available.
You certainly cannot use Windows.pas under OSX. Because Windows.pas exposes the functionality of the Win32 library.
If you need to execute Win32 code on OSX pretty much your only option is Wine.
A more plausible solution is that you find an alternative to this "special" library to which you refer.
Windows.pas is mostly a wrapper around different DLLs contained in the Windows operating system. As it is unlikely that you will find those DLLs in OSX I guess you are out of luck.
You could check the library's source code and try to identify the constants, procedures and functions that are used in windows.pas. If it is not too much code you could try to modify the library so that it uses corresponding Carbon functions instead.
While the various answers are correct, and the vast bulk of unit windows is not portable, some functionality IS abstracted. Structures like interlockedincrement, Rect and ColorRef, and some message related functionality. Have a look at types and lcltype and the system unit interface of FPC.
A lot of Delphi code still uses Windows for that functionality, while e.g. unit types already exists since D6.
Some other things are abstracted, but not using the same (windows unit) calls. Better explain what exactly you need in a separate post.

Delphi cross compiler for linux

I was wondering if there is any Borland cross compiler that can make my windows code work on linux without wine.I'm using winxp with delphi 7. I was always wondering if it was possible to code same tool I coded in windows , again in Linux and how is it possible to code same tool by using pascal code in linux.Thanks
The best solution is Lazarus, the delphi-like GUI for Free Pascal. If you were using "pure" vcl, without Windows internales or any special add-ons the migration will be a pice of cake :)
Take a look here: http://lazarus.freepascal.org
BTW - Lazarus and FPC are true mulitplatform - you can compile code for Linux, Windows, MacOS and more with the same codebase :)
Your only option, if you want a Borland Delphi cross-compiler, is CrossKylix. This isn't a real cross-compiler. Instead you run the Kylix compiler for Linux under an emulated Linux environment.
Note that you'll be forced to use CLX rather than VCL and that Kylix is well and truly dead nowadays. Personally I think Wine is probably an easier and better option.
First of all, it all depends on what system functions you used in your programm. In most cases, there will be no possibility to cross-compile it under linux.
But, in some cases Borland Kylix can help, but, afaik, it's almost dead now.

Coming from making Windows-only programs in C#, what steps are there for developing for Linux AND Windows?

I want to start making a little window-based program that runs on both Linux and Windows flawlessly.
It must have a GUI. What are the things I should be reading about? I'm completely in the dark regarding this.
Thank you.
If you want to leverage your C#/.NET knowledge (IronPython,...), you should go with Mono. Its IDE is called MonoDevelop and works in Linux, Mac and Windows. You can keep using WinForms or switch to Gtk#, which is a nice wrapper around gtk+.
Also, make sure you read the application portability guidelines which covers different strategies and common pitfalls.
Enjoy!
You could try Java and run the same compiled bytecode in both places. Or try C++ with Qt or wxWidgets. With C++ though you will have to compile for each platform. Another possibility is Tcl/Tk
As a C# developer, I'd suggest Java with the Swing toolkit. NetBeans helps you get started easily, like Visual Studio.
Download, install, create a new prject, and there you have it; a form in front of you to drop controls and hook up to the code just like in VS + C#, except it's cross-platform (write once, run anywhere). And the language is very similar to C# (which was actually inspired by it). There are also countless books to help you get started with Java and GUI development in it too.
If you don't like Java for some reason, and you're willing to learn/use C++ (with extensions), have a go at Qt, and the Qt SDK, which includes a form designer as well, with a really nice IDE GUI. If you know C++, Qt should be a breeze. It's also cross-platform (write once, compile anywhere).
Good luck.
If you want to utilize your C# knowledge, you might want to have a look at Mono. But there are many, many other alternatives too.

Programming language for GUI compilable to native binary

I need to write an app that reads a config file with info on the menu bars it needs to create.
Normally, I'd just use java, but I need the application to have the least run-time dependencies possible, this includes not forcing the user to download anything, even JRE, let alone something like NET Framework.
So I need something that can compile to an EXE (windows only for now), and that will allow me to CODE the GUI, so I can dynamically create it from my config.
BTW: something like C++ is a bit too low level, all I need is to create menus, and display HTMLs in a panel.
How about wxPython together with py2exe?
There is a nice tutorial on how to do it here.
If Java's too high-level and C++ too low-level, there ins't much in-between. Maybe Delphi?
I wouldn't totally write off using Java and/or Python for a few reasons.
1) py2exe can compile your Python code to an exe.
2) GCJ can compile your Java code to an exe.
Delphi is best chose for you. Because Delphi compile source code into native x86.
Unless you have serious reasons to avoid interpreted languages, I would suggest you better look into ways of packaging or compiling interpreted scripts because doing this will likely reduce your learning and development time.
I would write a simple GUI in Tcl/Tk, and then package it as a Starpack.
ActiveState provides a distribution (ActiveTCL) and a decent editor (Komodo Edit), and it is fairly easy to get simple GUIs going with Tk. Check out TkDocs for some hand holding.
Once you're done, you can package your code, a Tcl runtime, a database, and a virtual filesystem, all into a single executable that you can easily distribute.
Earwicker is right. You can use HTA:
http://www.interclasse.com/scripts/htanotepad.php
But if you know C++, then creating this type of an application is actually very easy with Visual C++. Use MFC, and statically link everything. You can draw the menu in the resource editor, and attach events to the menu items. I wouldn't use HTML if I were you. Just use regular Windows controls. But if you're really set on using HTML, you can embed a Browser control in the formview.
Have you considered D ? It has a syntax that is like a mixture of Java, C++ and Python with the ability to make native windows apps. The tutorials on dprogramming.com are great to get up and going with the language. For quick GUIs you'd be interested in The D Forms Library and the Entice Designer.
Here are some short video tutorials to get up and running with Entice.
Alternatively, have you tried Qt & Qt Creator? It takes a lot of the hair pulling out of C++ Programming and it's also cross-platform.
You say:
all I need is to create menus, and
display HTMLs in a panel.
A lot like a Web browser, then. If it's going to run on Windows, then the user has IE. Why not use IE to do all the work for you?
You can make something a lot like an .exe with IE, called an .hta:

Good resources for writing console style applications for Windows?

For certain programs nothing beats the command line. Unfortunately, I have never seen good documentation or examples on how to write console applications that go beyond "Hello World". I'm interested in making console apps like Vim or Emacs. Well not exactly like Vim or Emacs but one that takes over the entire command prompt while it is in use and then after you exit it leaves no trace behind. I know that on Unix there is the curses library but for Windows? ...
PDCurses works on Win32.
I found List of Console Functions on msdn, PDCurses, and The Console Module.
You can certainly write that kind of application with Delphi, which has reasonable commandline support. People often overlook that Delphi can build any kind of Windows executable, not just GUI apps.
I don't know off-hand if the free 'Turbo' edition of Delphi has anything cobbled into it to PREVENT you from using it to build console apps - I would have thought it would be fine for this kind of thing.
There is a small but good tutorial on using C++ for the Windows console at www.benryves.com/tutorials/?t=winconsole&c=all going as far as coding a simple painting program.
You could also try Free Pascal. It is a free ((L)GPL) Object Pascal compiler which is compatible with the Delphi-compiler. It has an console-based IDE, which proves that you can make very good console-applications with it, and which you can use as an example.
If you want to use a graphical IDE to build your console-application, you can download the Lazarus IDE.
As a bonus your application will run on Windows (32/64 bit), Linux, Mac OS X, FreeBSD, Solaris etc...
In Windows or DOS, I used the conio library from Borland. It's very old but fine enough for a beginner like me.
As Robsoft says Delphi would be a good start. There is Turbo Delphi (Pascal based) or Turbo C++ both free editions.

Check out some of the mono libs. They have a great one to parse command line arguments but can't remember the namespace.
Miguel just posted some terminal code as well.
For ncurses-like library/framework on Windows, I'll highly suggest to get your hand dirty with PDCurses.
If you trying/using C#, there's Curses-Sharp.
This is the best tool for it I've ever seen!!
1) Create any application using VB6 IDE
2) Convert it to Console Application, using THIS!
