How to clear console in Windows - windows

I want to clear the console
I tried using this, but it doesn't work for Windows
print!("\x1B[2J");
Is there an easy way to clear the console?

I think I need some clarification first, on what you're attempting to do. Regardless, this is my best attempt at answering your question <3
Preamble
Given that different terminals work differently and have different APIs, I think you probably will want to use a crate that provides this functionality in a cross-plaform manner.
I'm assuming from here on that you want cross-platform functionality and that you don't mind using external dependencies. If this is correct, you might be happy to know that the terminal interaction crates are actually really developed in the Rust ecosystem. I have heard only good things about them.
With that out of the way, let's move on.
Do you want to just perform actions on the terminal?
If you just want to perform some actions on the terminal, like "clearing", "scrolling", "moving the cursor" and whatnot, I think you will be satisfied with the terminal crate. It allows to perform many actions, like clearing, independently of the platform you're in. It also allows for using interactivity features like interacting with the Mouse and the Keyboard :3
Or do you want to write a GUI for the terminal?
If what you want to do is write a Console-based User Interface though, I think that what might work for you instead is the tui crate. It has all of what you need to build terminal GUIs, from clearing of the console up to graphical widgets. Tools like gitui are written with tui.
Did I answer your question? Feel free to follow up if I fell short :)

Graphics To Console

im not even sure if what im asking for is possible.
i want to create a really lightweight interface for the RPi. it doesn't needs to should much in terms of graphics, but i would help.
i want to display data onto the unix console (so i don't have to start up a GUI desktop like Gnome).
but i don't even know what to google for what i want. basically, when installing something like Ubuntu, you get the console screen but it slightly formatted (unlike just logging to the console).
i want to create an interface similar to what might see when you load the BIOS menu. how do i do this?
it would also be really useful if i could get some touch functionality so if i touch certain parts of the screen it would register and i could get the interface to behave as i need it to.
You did not specify a programming language so maybe dialog will do.
ncurses is well known for C.

Any recommendations for writing a GUI client from a CLI client?

I'm looking for writing a GUI client for a existing application in my job, this application is CLI and because this is not widely used.
This is the first time I'm writing something similar, the I ask you for recommendations, books, techniques, methodologies, advices. My first approach is to create the interface and to make calls to the original CLI client, is this a congruent approach?
Though it's not ideal, I don't think it's a bad approach, creating a GUI shell for your CLI app. In this design, the GUI acts as the CLI program's user. You have to consider things like:
Can the GUI anticipate or understand
all possible CLI program output? How about errors? How
complex will that be? Consider
parsing Unix "ls" output. Simple enough. How
about Windows command prompt "dir" output? A
bit more funky.
The CLI program may take time to
execute, this must be presented in
the GUI. The GUI may have to prevent
the user from running another instance of the CLI.
You might want to consider tcl/tk. I've written several successful commercial GUIs that work in exactly this manner.
I'll admit that it maybe takes a little skill to craft a stunning GUI but it's not impossible, and not even that hard. You won't be able to reproduce the eye candy of flash or silverlight, and if that is important this might not be the right solution for you.
If, on the other hand, you are more concerned with Getting The Job Done, tcl is a very viable choice. It's easy to learn and easy to I integrate with command line tools.

How create custom user interface for Windows?

There are many applications for Windows these days that don't use native windows controls, don't have standard window frames and generally look different. What are some recommended techniques for creating such interfaces?
There are good reasons not to. Like that you will most likely not do a better job than Windows does. (Maybe it will look better (in your opinion), but will it behave?). Or that it's not what most users expect. Or that it will look like s**** on Windows 2011.
That said, it's not hard. You simply handle the WM_NC* events like WM_NCPAINT or WM_NCHITTEST. NC stands for Non Client (window area). And of course, there is a trick on Vista/Win7 (you have to announce it to the DWM).
From an implementation aspect, you could employ WPF (Windows Presentation Foundation) assuming you code for .NET :) It has pretty bunch of skinnable controls, that may look like native and may not.
From a design aspect, if your interface isn't going to follow documented standards (like the Windows UI guidelines), it has to be intuitive. I think the new generation of Windows applications will go through a growing phase in a manner similar to the early days of the Web. After a time, some standards or common themes will evolve.
Can you give us some sample applications? Some apps that don't use native windows controls use cross-platform GUI libraries, like Qt for C++ or Tkinker. These maintain the same look across different platforms.
I wouldn't really recommend making your user interface different deliberately. You don't stand to gain much. Your controls are almost always going to be buggier than native controls, and you are requiring the user to learn something new. Now, if you're controls add a large enough value to be worth the users' time it can be okay. But making them get used to different looking buttons is rarely worth it.
I`m not sure if this answer your question.
You can use third party skinning controls like from Infragistics, or SkinSoft for example.
But like Bubba said I`d recommend going for WPF.
Model-View-Controller! It's as valuable here as in web apps or anywhere else. Be sure to keep the part of your program that generates the custom UI separate from the part of your program that flashes the BIOS.
I know this question is 10 years old but none of the answers mention using an option in visual studio, dont know if it existed at the time.
Theres an option to remove the border of the window in visual studio (called borderStyle). Thats the easiest way to do it, using C#. After removing the border, all you have to do is create a new interface. If you're looking to do it in C++, i think you need to use DWM. I will let an example i found here.

Another example (maybe without DWM? didnt test):

There is a lot of people disencouraging to do it in this thread but there's no reason to not do it, if you know what you're doing your application can look great.

How to control the mouse pointer outside our application

I want to control the mouse pointer with my application and be able to interact with other programs using my program,
For example I want my application to be able to click on a button on another application
How should I go about solving this problem?
(Any programming language would work, also if you have any suggestion please let me know)
Afterthoughts:
I want to do it in windows operating system and want to test my GUI to see if it works in different scenarios. Any language would work for me since this is not part of the final product but I prefer one of these languages (Python, Java, C# or MATLAB)
Thanks
There are many ways of doing this, and you didn't mention any details of your application (system, target goal, etc...).
If your goal is menial automation, I'd recommend whipping together a quick AutoIt script on Windows. http://www.autoitscript.com/autoit3/index.shtml
If this isn't what you're looking for, please give more details.
Okay, this one is really operating system and windowing specific. But the phrase you're looking for is "mouse grabbing".
As #Mitch suggests, unless you've got a really good reason — like maybe a GUI testing app? — then grabbing the mouse and messing with it in that way is very bad form.

When should I add a GUI?

I write many scripts at home and on the job. Most of the time the scripts get used only a few times to accomplish their chosen task and then are never used again. However, sometimes I write a script to do something more complicated, something that requires user input. It is at this point that I usually agonize over whether to implement a GUI or stick with a y/n, press 1-10, etc. command-line interface. This type of interface can become tedious to use and difficult to maintain.
I know some things lend themselves to a GUI more than others, such as selecting things in a giant list. However, the time it takes to switch a command-line application to use a GUI is prohibitive. For me, it takes a good amount of time to add a GUI with even the most simple framework I can find.
I am curious if any developers have a method of determining at what point their script has grown enough to need a GUI. Or am I going about this the wrong way, should I always be writing my scripts assuming I might later add a GUI?
This doesn't answer your question but FWIW an intermediate step, between UI and command-line, is to have a configuration file instead of a UI:
Edit the configuration file
Run the program
A configuration file format can, if necessary, be complicated and well-commented.
As with many questions of this type, the answer is that it depends.
If your program/script does just one single thing by receiving a number of inputs from the user, it is better to stick with the non-GUI mode.
If the application is doing more than one thing and if you think that the user will use the application to do a lot of stuff, you may consider using a GUI.
Are you planning to distribute this program to others? Then it is better to provide a GUI.
If the users are non-technical, a GUI is a must!
Thats it.
When you want to hand your stuff over to someone else in a discoverable way. Command-line scripts are awesome because they are simple and elegant, but they are not very discoverable. That is, if you were to hand your scripts over to someone else with no documentation, would they be able to figure out what they are and how to use them? If your tasks are so simple that myscript /? will explain what you need to do fully, then you don't need a GUI.
If on the other hand, you are handing your scripts over to someone who isn't so technical, or needs some more visual guidance about the task to be done, than by all means, a GUI is a good way to go. You might even want to keep your scripts as they are and just create a separate GUI that runs them for maximum flexibility.
I think this decission also depends on the audience who will be using your script: If it is people who are comfortable working with the command line, then there is not pressing need to add a GUI as long as your script has a good /help which explains all the parameters it accepts. But if you want the "average user" to be able to use your program, I'd rather add a GUI because otherwise your program might not be intuitive enough for that user group.
If you only need some "Dialogs" to improve your scripts, you can use KDE Kdialog or Gnome Zenity.
I can't count the number of times I've written what I thought would be a 'one-off' and it became more useful than I thought and ended up writing a GUI for it, or I've need to come back to use a program months later. The advantage of the GUI is it makes it easier to remember what would otherwise likely be command line arguments. I.e. for flags and options you can simply use check boxes, combo boxes, radio buttons, and file selectors filenames. I use Borland C++ RAD so it is quite quick and easy to throw together a simple (or even not so simple) dialog box. I now often start with creating the GUI.
If you use Linux, try Zenity. It's an easy to use tool to make a GUI for command-line programs.
