creating iSeries like programs - c#

my main language is vb/c#.net and I'd like to make a console program but with a menu system.
If any of you have worked with "dos" like programs or iSeries from IBM then thats the style I am going for.
so, was wondering if anyone knows of a "winforms" library that will make my form look like this. I dont mind a "fake winforms look" or a console application but thats how I'd like.

I've used iSeries extensively and I remember exactly what you're talking about. To simulate this look and feel in a C# app, you'll want to create a console project and write text to different areas of the screen with the help of the Console.CursorTop and Console.CursorLeft properties, then calling Console.Write or Console.WriteLine to write out the text in the previously set position. To change colors, before calling WriteLine you'll want to use the Console.ForegroundColor and Console.BackgroundColor properties.
You'll need to listen for input and upon finding a tab character, your program can use its own internal logic to determine where the cursor should appear next (on the next line in the same column, for instance, to simulate those left columns of input fields in your screenshot).
Doing this with a Windows Forms app will be a little trickier and you'd definitely want to write your own control for it (possibly sub-classed from one of the many types of standard multi-line text controls already available).

It's a good question. For many Use Cases the standard Windows (or other windowing) paradigm can be overkill, intimidating, and confusing.
Back in DOS days there were a number of "Windowing" libraries that created various abstractions for doing this.
[After Googling]
Here's a site that lists various libraries including a several that appear to be of interest.
A resource like this would also be handy for Mobile apps, where mouse-driven window apps tend to be not the best fit, especially for workflow-type processes. The Console is a pretty universal lowest-common-denominator abstraction available in most every environment.

You are looking for a curses like library but for windows. And usable from VB & C#.
Curses provides for a even richer text based UI than even iSeries. All sorts of widgetry!
Windows is not really supportive of text interfaces whether on purpose or not so are out of luck.
But ...
Well, how about MonoCurses? I don't know if it will work though. Also look at PDCurses.
And if you don't mind using Python for just the front-end see this.

There are a couple of webifiers or screen scraping programs for iSeries that will create a web or windows user interface on top of your iSeries application. I have never used any of those so there is not a particular one that I can recommend, but you might want to look their for inspiration or reuse.

Get caret position in non-GDI apps

So I'm writing an accesibility app that needs to know the location of the text entry caret. I tried GUIThreadInfo, but while that works in basic apps like Notepad, it fails in more complex ones like Chrome, iTunes, etc. that handle their own UI.
Is there even a way to get the caret position from apps like this?
Yes, doesn't work. The caret is an implementation detail of user32, associated with a window. Applications like browsers don't use window controls, far too expensive. And they don't have to, there's a separate API to allow such programs to provide an interface to accessibility apps like screen readers. Start reading here. Not easy to use from a C# app, this project can lessen the pain. No endorsement, never actually used it myself.

Need help in finding name of specific thing I'm trying to do

I think it's possible to somehow hook with the windows environment (specifically explorer.exe) and trigger specific things, for example launching control panel and using it as if I had mouse (meaning I'm clicking the interface from the code).
Basically what I'm trying to do is automate some redundant tasks I do often, just I don't know how it's done, or even how it's called. Anyone can point me in right direction?
Thanks!
Forget about "automated clicking". GUI tools are just front-ends to control the system. You can control the system like they do, it will be much easier.
Huge possibilities can give you Microsoft Management Console. Each "snap-in" can be accessed via COM model. Some of them have GUI front-ends, find and fire "*.msc" files (somewhere in Windows directory) to try them.
There is many command line tools i.e. "net" command has huge abilities related to networking.
PowerShell may be a better choice instead of C# or C++, it's designed for task automation. You can easily use COM, .NET, MMC ...
Windows Explorer has a COM object model that you can call from both C# and C++. (Most of the examples on MSDN are in Javascript or VBScript, which I guess aren't your languages of choice, but they demonstrate that the API is straightforward to call.)
AutoHotKey is a scripting environment specifically designed for this sort of task
If you want mostly to launch control panel you can do using RunDll32 interface existing in the most control panel applets. See http://www.osattack.com/windows-7/huge-list-of-windows-7-shell-commands/ , http://support.microsoft.com/kb/167012 or http://www.winvistaclub.com/t57.html for example. For the corresponding API see http://support.microsoft.com/kb/164787.
Another option is usage of control.exe (see http://msdn.microsoft.com/en-us/library/cc144191.aspx and http://vlaurie.com/computers2/Articles/control.htm).
If you google more you will find much more examples which you can to automate a lot of things without using of some general ways to automate GUI.
At more or less the lowest level within Win32, you can use the SendMessage() API to send raw click messages to windows of interest. This will rely on a lot of intrusive knowledge about the apps you intend to drive. However, you could easily implement a "click recorder" that could replay click sequences captured from user interaction.

Windowing System for .NET Console

Does anyone know of any simple .NET windowing systems for the console?
I'm looking for something that manages areas of the console such that they are automatically scrolled independently of other areas. For example, I could create a status strip down the bottom and a main content area above it. It would also be useful if it handled colors for me.
Thanks,
Kent
A while back I took a look at MonoCurses and Curses#. I don't think MonoCurses supports independent scrollable areas, but I feel like Curses# should.
I wanted this style interface so I could have one interface for windows and linux. In the end I just went with a normal command line interface.

How to produce a colored GUI in a console application?

For the following questions, answers may be for C/C++, C#, or Python. I would like the answers to be cross platform if possible but I realize I will probably need conio or ncurses
How do I output colored text?
How would I do a GUI like top or nethack where certain things are "drawn" to certain spaces in the terminal?
If possible a small oneliner code example would be great.
Yes, these are VT100 escape codes. The simplest thing is to use some flavor of Curses. Once, you choose a curses flavor it is pretty simple to do both 1 and 2.
Here's a HowTo on ncurses.
http://web.cs.mun.ca/~rod/ncurses/ncurses.html
From this point of view, the console is in many ways just an emulation of a classic terminal device. Curses was created originally to support a way of doing common operations on different terminal types, where the actual terminal in use could be selected by the user as part of the login sequence. That heritage survives today in ncurses.
The ncurses library provides functions to call to directly position the cursor and emit text, and it is known to work for the Windows Console (where CMD.EXE runs), as well as on various *nix platform equivalents such as XTerms and the like. It probably even works with a true Dec VT100 over a serial line if you had such a thing...
The escape sequences understood by the VT100 and later models became the basis for the ANSI standard terminal. But you really don't want to have to know about that. Use ncurses and you won't have to.
Leaning on conio won't get you cross platform, as that is a DOS/Windows specific API.
Edit: Apparently the ncurses library itself is not easily built on mingw, at least as observed from a quick attempt to Google it up. However, all is not lost, as ncurses is only one of the descendants of the original curses library.
Another is PDCurses which is known to compile and run for Windows Consoles, as well as for X11 and a variety of *nix platforms.
(I was just reminded from chasing references at Wikipedia that curses came out of writing the game rogue, which is the ancestor of nethack. Some of its code was "borrowed" from the cursor management module of the vi editor, as well. So spelunking in the nethack source kit for ideas may not be a crazy idea at all...)
Most terminal windows understand the ANSI escape sequences, which allow coloring, cursor movement etc. You can find a list of them here.
Use of these sequences can seem a bit "old school", but you can use them in cases where curses isn't really applicable. For example, I use the folowing function in my bash scripts to display error messages in red:
color_red()
{
echo -e "\033[01;31m$1\033[00m"
}
You can then say things like:
color_red "something has gone horribly wrong!"
exit 1
Not cross platform but for Windows / C# colour, see
Color your Console text (C#)
c++
In C#, you can set the text color and the background color via the Console.ForegroundColor and Console.BackgroundColor properties, respectively. For a list of valid colors, see this MSDN doc.

What is a good project to learn Windows Forms programming in C#?

I want to learn c# so I can do some desktop developing. I've developed command-line C# applications and wanted to expand to Desktop applications.
I was thinking of create a screenshot tool like Jing or maybe a plugin for outlook to sync contact information with a service like Google.
What are your thoughts? My past experience is with web applications built in PHP.
I would try to start with something fairly contained, which only touched a few new technologies. For instance, if you want to learn Windows Forms, write something which uses that but doesn't need to talk to Outlook, Google, or the Win32 API. Once you've got the hang of Windows Forms, try one extra technology - try displaying your Google Contacts and do offline editing, for example. Then add another technology... etc.
In my experience it's hard enough to learn one new technology at a time - but that's far quicker than trying to learn two or more in one go. You inevitably get to the stage where you don't know where the problems are, and you have no confidence in any of your code because it's all new. This is particularly important if you're still fairly new to the language as well - although I'm glad to hear you started with some console apps :)
Sorry if that sounds like I'm being a wet blanket, and I realise it sounds like you'll take far longer to get to something useful that way, but I think you're more likely to be successful in the long run.
Find something that most importantly interests and excites you. If you pick something too boring that you don't care about you'll only give up before you get anywhere, and won't benefit at all. Don't do a rubbish project for the sake of learning a language. Do a good project, and do it in a new language as a side effect.
Make a notepad clone. While being fairly simple it will give you a primer in some basic Windows Forms mechanisms such as using menus and reacting on their events, getting input from controls for storage on disk, reading from disk and updating controls, using Docking and Anchoring and so on.
Twitter clients are the new hello world.
I read that somewhere the other day. I can't personally comment on its fitness for your goal.
Do something that you did before, but in another language. Then you won't have to think about most of the architecture of the particular task again, but you'll be able to compare the languages, the frameworks and their approaches.
I bet you'll learn a lot about your previous language as well doing this excercise.
A good project would be a simple windows form. You simply have a chance to put everything together. Or at least see a bigger picture.
You can make it as complicated as you want, without sticking to one area.
Suggesting a specific project is pointless. Think of something that interests you, or an application you want/need, then start making it - searching Stackoverflow/Google/MSDN/etc whenever you can't guess how to do a specific task.
For example, I had to make kiosk application that allowed customers to signup to a companies mailing-list. I tried using the Ruby framework Shoes, but it didn't work correctly on the laptop the application was to run on. Visual C# seemed like a better fit, and would almost certainly run correctly..
So I installed Visual C# Express, added a few labels and a button. I double clicked the button, and realised I didn't know the code to create a new WinForm window.. So I searched Google for "visual C# open new dialogue" or something, and I found out I had to add a new form, then call NewForm newwindow = new NewForm(); newwindow.show(); or similar.
Then, I added the username/email fields, then searched for "how to display an alert box" and checked I could display the form values.
That all worked, so now I had to decide how to store the emails. I had heard good things about LINQ to SQL, so looked into that, decided I wanted to use SQL Server CE (so I didn't have to install/run SQL Server on the laptop). That resulted in more searching around for how to make LINQ to SQL work with SQL Server CE..
Finally, I wanted to have a configuration panel to change the title/button strings etc (accessible via a certain keyboard shortcut).. A Google search revealed how to catch keystrokes, and I asked a Stackoverflow question about representing the settings (using a PanelView or something)
..anyway, the point of that slightly long, rambling and not terribly interesting story is.. You can learn many new technologies at once, as long as you have a specific application in mind (and you're determined to finish it!)
I learned C#, WinForms, SQL Server CE, LINQ to SQL, and simple application publishing stuff in a day - creating a functioning, useful application in the process - simply with a combination of prodding around, Google searches and Stackoverflow..
