• Looking for reading material on application architecture with web UI

  - by toong

  I'm looking for articles (or other reading material) on the topic of fat client applications with a web UI layer. Open-source projects that use this architecture would be very interesting too. Such an application would embed one (or more) browser-window(s) (chromiumembedded for example). You would need bidirectional communication between your web-UI and your domain model/services. I think this allows quick prototyping the UI, a clean separation between logic and UI and potentially easier portability across platforms (compared to WinForms for example). But that is just my view, I was looking for the view of people who have been on that road. An example of an application using a web-ui layer is Light Table. Unfortunately it is not open source (at this point?).

• C# Concisely by Judith Bishop &amp; Nigel Horspool

  - by MarkPearl

  In my quest to read all the books I have lying on my bookshelf I have finally got round to finishing C# Concisely (ISBN 0-321-15418-5). While this book was fairly old, I found it to be quite useful for a student wanting to learn C# for the first time, and a nice way to review and make I hadn’t missed something when I was learning the language. The book is simple and explains the basic concepts in a clean manner, but is really intended for the beginner programmer – it also had a few chapters dedicated to winforms, which was an indication of its age. None the less, I will keep it on the bookshelf so when I come across someone who is wanting to learn the language I can give them it as a gift.

• Coding a web browser on Windows using a layout engine?

  - by samual johnson

  I've never attempted anything like this before but what I want to do is code a browser for Windows. I know that I can use the web-browser control that Microsoft has released, but I'm interested in seeing how the problem is solved from a lower level. So I want to know what layout engine I should be looking at? Or is a layout engine the best way to go? I've been looking at WebKit, but it seems rather Mac-centric, so I'm wondering if there are any more practical one's for windows? Has Microsoft released the source code for their webbrowser winforms control in the .Net framework? That would be dependent on the CLR anyway, I suppose? Any suggestions?

• Graphically intensive silverlight design

  - by Rick Hodder

  I'm designing a silverlight application for showing sheet music from a midi file. I want to create a horizontally scrolling musical staff. At my job I maintain a winforms application that is a scrolling Gantt chart of airplane schedules, and it basically has a rows collection, and it maps the left-most pixel and right-most pixels of the control to datetimes. Then the paint method loops through what it determines will be the visible rows, and draws a screen that shows the schedule information between the two dates. Would I be correct in assuming that I would need to something similar in silverlight for my sheetmusic, or would it be better to just create a horizontal scrollviewer containing a canvas that I have drawn programmaticially on. Am I headed in the right direction? I havent seen any articles on designing such a custom control: can you point me at any?

• How to choose a new technology for mastering and not lose sense of reality and practicality?

  - by Eyewan

  How to choose the right next step in learning programming and mastering new technologies? I have experience with WinForms applications in C# .NET. Next what I see as a good area of expanding the knowledge is ASP.NET. Language I already know, C #, so I think there is now more a matter of mastering new technologies. Also I have interest in WPF. Perhaps the best is to work on ASP.NET and WPF at the same time. Sometimes the problem is when we do not have motivation, but also known to become a problem when we want to much :) How to choose a new technology for mastering and not lose sense of reality and practicality?

• Book about tcp, http, named pipe, shared memory, wcf and other inter-process communication protocol

  - by Samuel

  Recently, I had to create a program to send messages between two winforms executable. I used a tool with simple built-in functionalities to prevent having to figure out all the ins and outs of this vast quantity of protocols that exist. But now, I'm ready to learn more about the internals difference between each of theses protocols. I googled a couple of them but it would be greatly appreciate to have a good reference book that gives me a clean idea of how each protocol works and what are the pros and cons in a couple of context. Here is a list of nice protocols that I found: Shared memory TCP List item Named Pipe File Mapping Mailslots MSMQ (Microsoft Queue Solution) WCF I know that all of these protocols are not specific to a language, it would be nice if example could be in .net. Thank you very much.

• IncidentsTracker v1.2 Screenshots

  - by samkea

  he IncidentsTracker v1.2 System is a system that was developed to track Incidents happening in any particular country. It is incorporated with a maping component to enable end users search for places where an incident has happened, enter data about it and then produce reports.It's a Winforms software that was developed in a plugin style using C#  with an extensibility pattern/framework. It sits on an SQl Server backend but can also use any other databases prefered. Its Administrator just has to add the path where the database will be and it will autio create the database. This software was orignally developed to help UN Agancies and NGOs in thier work but can also be ustilised by other entities like the police, the human rights organisations, roads authority, etc etc. The development of a newer version(IncidentTracker v2) has been started in silverlight.

• Using a back-end mechanism to copy files to DB and notify the application

  - by BDotA

  This Scenario: User copies large files to a local folder. I want to watch that folder and when a new file is dropped then go and copy it to Database, so later when coping is done I can actually use it in my application. ( A C# WinForms App). It would be awesome to also find a way to somehow get notified in the Application that hey copying the file to DB is finished and ready for use... I am using C#.net, Windows... What solutions/architecture do you suggest for this? For example having a windows service running all the time watching that folder, when something copied goes and write it to DB ... then how about getting notified? MSMQ is something I can use? don't know much about it yet. Thanks.

• How would you design an application with many target platforms and devices?

  - by Pierre 303

  I'm in a very beginning of the design phase of an application that will have to run in the following platforms/devices: Desktop: Windows, Linux & Mac Mobile: Android, iPhone/iPad & Windows Phone 7 Web: Silverlight I will use C# on Mono and I want to maximize code re-usability. Except for the desktop (I'll use WinForms/GTK#), my concern is related to many different GUI that I will face. What would be your approach? Obviously, the views will be different, but what about the controllers, data access, utility classes, etc. Is it really acceptable to share everything but the views?

• Service Layer - how broad should it be, and should it be used also on the local application?

  - by BornToCode

  Background: I need to build a main application with some operations (CRUD and more) (-in winforms), I need to make another application which will re-use some of the functions of the main application (-in webforms). I understood that using service layer is the best approach here. If I understood correctly the service should be calling the function on the BL layer (correct me if I'm wrong) The dilemma: In my main winform UI - should I call the functions from the BL, or from the service? (please explain why) Should I create a service for every single function on the BL even if I need some of the functions only in one UI? for example - should I create services for all the CRUD operations, even though I need to re-use only update operation in the webform?

• How do I start correctly in building database classes in c#?

  - by e4rthdog

  I am new in C# programming and in OOP. I need to dive into web applications for my company, and I need to do it fast and correct. So even that I know ASP.NET MVC is the way to go, I want to start with some simple applications with ASP.NET Webforms and then advance to MVC logic. Also regarding my db classes: I plan to create common database classes in order to be able to use them either from WinForms or ASP.NET applications. I also know that the way to go is to learn about ORM and EF. BUT I also want to start from where I am feeling comfortable and that is the traditional ADO.NET way. So about my Data Access Layer classes: Should I return my results in datasets or arraylists/lists? Should my methods do their own connect/disconnect from the db, or have separate methods and let the application maintain the connection?

• Are there any advantages to using ASP.Net MVC 3 over Ruby On Rails for existing businesses? [closed]

  - by user786621

  Possible Duplicate: What ASP.NET MVC can do and Ruby on Rails can't? I've been hearing a lot of good press about Ruby On Rails but I'm having a hard time finding much information on the advantages of using ASP.Net MVC 3 over RoR, yet I see many existing businesses migrating over to ASP.Net MVC. Does ASP.Net MVC 3 have any advantages over Ruby On Rails for existing businesses such as possibly tying into old databases better or allowing for more complex business logic? Or is it most likely the case that they are transferring simply because they were already using ASP.Net for Winforms?

• How can I permute pairs across a set?

  - by sila

  I am writing a bet settling app in C# and WinForms. I have 6 selections, 4 of them have won. I know that using the following formula from Excel: =FACT(selections)/(FACT(selections-doubles))/FACT(doubles) This is coded into my app and working well: I can work out how many possible doubles (e.g., AB, AC, AD, AE, BC, BD, BE, etc.) need to be resolved. But what I can't figure out is how to do the actual calculation. How can I efficiently code it so that every combination of A, B, C, and D has been calculated? All my efforts thus far on paper have proved to be ugly and verbose: is there an elegant solution to this problem?

• SAML Request / Response decoding.

  - by Shawn Cicoria

  When you’re working with Web SSO integration, sometimes it’s helpful to be able to decode the tokens that get passed around via the browser from the various participants in the trust – RP, STS, etc. With SAML tokens, sometimes they’re simply base64 encoded when they’re in the POST body; other times they’re part of the query string, which they end up being base64encoded, deflated, then Url encoded. I always end up putting together some simple tool that does this for me – so, this is an effort to make this more permanent. It’s a simple WinForms application that is using NetFx 4.0. Download

• Service Layer - how broad should it be, and should it also be used from the local application?

  The background: I need to build a desktop application with some operations (CRUD and more) (=winforms), I need to make another application which will re-use some of the functions of the main application (=webforms). I'm using service layer for reusing my functions. The service is calling the functions on the BL layer (correct me if I'm doing this wrong). so my desktop has 4 projects - DAL, BL, UI, WEBSERVICES. The dilemma (simple but I still need some more experienced opinions): In my main winform UI - should I call the functions from the BL - bl.getcustomers(), or do it similar to how I call it in the webform, and call the functions from the service - webservices.getcustomers? Should I create a service for every single function on the BL even if I need some of the functions only in one UI? for example - should I create services for all the CRUD operations, even though I need to re-use only update operation in the webform?

• Speed up content loading

  - by user1806687

  I am using WinForms Sample downloaded from microsoft website. The problem is, that the model loading time is quite long, using: contentBuilder.Add(ModelPath, ModelName, null, "ModelProcessor"); contentManager.Load<Model>(ModelName); even a simple model, such as a cube with no textures, takes 4+ seconds to load. Now, I am no expert on this, but is there anyway to decrease loading time? EDIT: I've gone thru the code and found out that calling contentBuilder.Build(); ,which comes right after contentBuilder.Add() method takes up most of the time.

• Old school trick that I forgot

  - by DavidMadden

  If you have to support some older Winforms you might like to remember this.  When opening a MessageBox to display that the user entered incorrect information, if you are doing so from a dialog, catch the DialogResult of the MessageBox and then set  this.DialogResult = DialogResult.None; to prevent the dialog from closing if you want the user to try again.  Otherwise, it will close the dialog box and return to the section of code that called it.Note:  You do not have to catch the DialogResult from the MessageBox.  You can still set this after the return from the call to the MessageBox.  Just make sure to do either but exiting the body of the dialog itself.

• Do we have ObjectForScripting property for WebBrowser Control, for Smart Device application?

  - by Sumeet

  I am aware of the ObjectForScripting property provided for the WebBrowser control, which is provided for WinForms application. I am using the WebBrowser control in a smart device application. I am not able to find this property. Is it documented somewhere that ObjectForScripting is not available for Windows CE? (Got solved in StackOverflow) Also, are there any alternatives? (Still need to know?) Kindly bear with me if I am not using the protocols of Stack Exchange. I am sorry to be unaware.
