I need to implement a check box which can have multiple states, I am new to Xamarin and OSX development. I could not find any built in control that I could use. I guess I need to implement a custom user control, which class should I derive from and how should I approach it?
I don't know if you checked this already, but this might help you :
https://developer.xamarin.com/guides/mac/user-interface/custom-controls/
It's not much as help but it might lead you to something. Hope it will help you at least a little bit. It helped me to start with custom controls as I am in about the same situation as yours, but with different kind of controls needed

I'm trying to create a Mac version of an iPhone app, and specifically I need to be able to pick a person from the user's Address Book, akin to the ABPeoplePicker on iOS. The look of the interface isn't particularly important (be it a separate popup window or a subview etc), I just need to pull up a list from Address Book and have the user select a row, and then feed the First and Last names from that contact back into my code.
But from what I can tell, that functionality doesn't exist for Mac, or else it isn't nearly as user-friendly and intuitive to implement.
Can anyone shed any light on how I might do this? Are there built-in functions I haven't found yet, or any good 3rd party code sources you can recommend?
PS I know enough to be dangerous, but I'm still very much a beginner. Code samples and tutorial links are very much appreciated!
Perhaps Apple's CocoaPeoplePicker demo can help you.
Here's the AddressBook framework reference
I cant decide between this two options.
M Project vs Sproutcore
I'm building an application that will be primary served on mobile but has to be viable on desktop.
Mproject is on the edge with number and variability of his prebuilded widgets and may happen that I will need some more or at least alter some behavior.
So this is kind of down side of Mproject. But it looked for first review that Mproject need less code for basic stuff.
And the second problem comes with the skins. I will basicaly need reskin everything a lot. The design of app has to be very unique.
So I want to know which of them is easily to reskin not just by theme-roller and similar stuff.
I would appreciate any other JavaScript-only frameworks recommendations.
Thanks for all replies.
I'm not sure what kind of application are you building so you should take care with my answer.
M-Project solved our problems fine, and help us to make it clear code ... when you understand how it works. It requires a bit of hard work, the documentation is a bit poor and is a new project where some things are not yet implemented. You can change application look modifying HTML and CSS so I think you should have no problems with this.
Also you can download their code and modify it without problems, it is easy to read and modify if you need any specific behavior.
On other side, I never used Sproutcore, it have a really nice look. But documentation say it is focused on desktop applications. Probably you will not have too much problems to adapt the output HTML for mobile devices, I guess.
Lastly, I think you can take a look on Lungo.js Framework.
Best regards.
I am working on building a system that can monitor how users react to security alerts on their systems (software updates, warnings etc.). It also needs to monitor the web traffic and the processes running on the system and I am looking to the community to help me design this system. We intend to provide users with test laptops and monitor their behavior over a period of time to see how they react to security alerts thrown by various applications and the OS(windows in this case).
Following are my questions
Can I use windows hooks to solve the first problem i.e finding how users reacted to the alerts thrown by various applications. Specifically, can global hooks be used to solve this?
(How this information should be collected (XML?) and relayed back to a server(how frequently?) is another problem)
Can I do this in C# or it has to be done only in c++ or VB?
Do you know any alternate approach to solve the problem? Is there any software that has these capabilities.
I have many more questions but getting these answered would be a good first step. Really hoping for some good insights from the knowledgeable people on this community
Thank you in advance
Edit:
Example scenario is when adobe prompts you to update the flash player or the antivirus prompts you to update definitions or any application displays a notification(security related having keywords like update, warning, install etc.) needing the user to take some action. Windows system updates is another example. I want to know how the user reacted to these alerts/notifications/updates (which are typically a pop-up window). So i was wondering if i placed a global hook that can monitor the content of the windows displayed on screen and notify me(server) when certain words like update, alert, warning etc. appear in the content/title of the windows and what the user did with the message(dismissed it, Oked it etc). Unfortunately, i do not have any more specifications than this. I can use anything I want to achieve this and I am not clear on what my choices are.
Edit 2:
After having reviewed my requirements and having read about hooks, I feel like I could achieve this by a combination of hooks and the following textGrab SDK, http://www.renovation-software.com/en/text-grab-sdk/textgrab-sdk.html. I want some guidance to know if I am on the right track. I am thinking if I can install hooks then it gives me handles to all possible windows on the screen and I can use the textGRAB SDK to look for certain keywords in those windows. Although this may capture some interesting text, I am still not sure how I will know what action the user had taken on the window. Anybody having any experience with either hooks or textGRAB, please let me know if this looks like a reasonable thing to do. If the community has some other Ideas on how I could possibly monitor security related messages thrown by any application in the system, please suggest. I am looking forward to some useful advice for completing a challenging project.
First of all, you need to define, how you will "see" security alerts in code. "Security alert" is quite a vague term. Will it be some window with some caption and some message to the user or ... ?
Next, about web and processes: Windows hooks won't help you with your task. They are more low-level and not as advanced as you'd need. You can't hook network traffic (you need either network filter driver for pre-Vista or Microsoft Filtering Platform for Vista and later). See this question for some information about checking the process list with C# (there seems to be no easy way to catch process startup either).
It honestly sounds like you need a more solid direction. I commend you for trying to provide details, but It appears that you still need more information about your problem(s)..
I will attempt to answer some of your questions, but like I said - it sounds like you need to know more about your problems before we can provide you with optimal answer(s).
-Alerts is too vague a term, you will need to define this better. Are these 'alerts' applications that YOU have control over or are they third party applications? Not every application will show an 'Alert' in the same fashion, and even if they did - I think using a System Level Hook would probably be too problematic to implement your solution with. I'm not saying it's necessarily impossible, but you're talking about possibly implementing a different set of logic(to determine the data for a given application's Alert(s)) for each application that you want to monitor.
-It's impossible for any of us to determine the optimal storage mechanism for your particular needs, that is something that you will either need to provide more details about or decide on your own.
-How often you collect data is also something that you will have to either provide more details for or decide for on your own.
-C/C++ Would probably provide you with the most portable solution, although there is nothing preventing you from using c# to call Win32 API. (Not everyone has the .NET framework installed - believe it or not)
-The problem that you mentioned appears to be a somewhat specialized problem... I don't know of any existing software that will do everything that you want to do.
Another possible issue that you haven't touched on:
You haven't specified your target audience for this 'service', but I want you to know that if I found an application monitoring as many events as what you're talking about doing, I would promptly remove it and write a nasty letter to the company that wrote it.
In summary, Read this Article on hooks to get a better understanding of how they work.
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.
https://github.com/melak47/BorderlessWindow
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.
Control Panel -> Security Center
I really like the components/controls which are used to show if a firewall or the Automatic Updates are enabled.
Are these reusable controls in C# or Delphi?
These components are internal to Windows and are not available to be used outside of the operating system (and are written in C++).
These are not reusable. They are built into Windows so you would need to either make your own custom version of these controls or find someone who already has if you want to mimic their look.
If you post a new question (or just add to this one) asking how to make something like it, and state what language/environment you would like to do it in, I'm sure we could point you in the right direction.
Yes, they are reusable (of course, as they are in ring 3 !!!)
Simply load them from ATL.DLL (C code had been posted several years ago on BBS...)
Some wrong and newbie answers are unbelievable...
