SignalR is very interesting and impressive in real time web applications. Now I am doing a simple chat applciation using windows forms.
Whenever, I use ".wait()", it threw an error 'one or more errors' and while invoke the message from text box, there is an error 'start must be call before send'.
I don't know where i made mistake. I tried many of the solutions. But it doesn't work. Everything is perfect in web and console applications.
Can anyone help me?
Can you give some examples with how it works...?
I couldn't see any samples of signalR in windows forms.
Assuming you are trying to do a SignalR Client in Windows Forms Appliation then check this post(http://mscodingblog.blogspot.com/2012/12/testing-signalr-in-wpf-console-and.html) on how to do client side SignalR in WPF application in VB. With similar approach I guess you could make Signalr client working in Windows Forms Application.

So this is the issue:
I have a .NET project that includes 5 Web Application Layers.
One of them is API.
I Recently added a Cordova project as well and I'd like it to communicate with the API Layer.
Is there anyone who knows what to do?
P.S.:
I use visual studio 2013.
You can use normal jQuery Ajax calls to make requests to the API. http://api.jquery.com/jquery.ajax/ or just normal JavaScript ajax https://stackoverflow.com/a/8567149/487940.
I hope that answers your question.
If you're talking about calling into Web API web services from a Cordova app, you may find the Breeze.JS framework useful to help you. You can either just used the client library or use some server side code in addition to client code to help get you up and running and exposing new web services as well.
Otherwise it is simply a matter of making web service calls to the server from your JavaScript code but the specifics will depend on exactly what you're trying to do and what client UI/utility framework you are using.
I have been building a Web Application (ASP.NET, .NET Framework 4, VB, visual studio 2010). To be very brief the application interacts with a database and performs several actions (Insert Delete Select etc..).
I am using several Gridviews, ListBoxes etc and I am not happy with the presentation outcome and the functionality provided by asp.net. In simple words my application looks bad, outdated and unprofessional.
I figured that using Windows Forms that will be incorporated to the ASP app would be a great improvement and solve all of my problems.
I have created a Windows Form Control Library to use the dll created in my app as a user control. I found out that this is not supported in .NET Framework 4 (is this true? or am i doing something wrong?).
Is there any way to make my application have the 'look and feel' of a windows application?
Please note that it is has to be a web app and the clients should not have to download any other application to interact with the server.
Have you checked out the third party controls from other vendors?
I currently use them for rapid development.

Anyhow all controls in .net you can change there look and feel using plain CSS.
Try using Silverlight 4, it has all that you need. What u are trying to do is traditional ASP.NET and that's as good as it can get coz its all server side code, but with Silverlight things are totally different, its all client side with specific server interactions. Have a look at the tutorials about how to use Silverlight and WCF RIA services to do what you are trying to do.
Try this link: WCF RIA services and Silverlight
Edit: Silverlight is designed to create stunning web GUIs. Just in case you were wondering what the heck it is.. :)
We're developing .Net Application using asp.net and C# and .Net Framework 3.5.
We are using windows form message box in a .Net application.
This windows form works great on the debug mode but once we publish the application this message box won’t work.
We are referencing System.Windows.Form.dll in order to use the message box features.
Kindly advice if we need to register this DLL or follow some configuration steps in order to solve this problem.
Thank in advanced,

Don't use MessageBox in a web application. It will show up on the server console, there's nobody around to click the OK button. I assume that ASP.NET has some counter-measures against it, given that it is such a serious denial-of-service attack.
If you are using unreferenced classes a project/solution is usually not even compiled.
So probably the problem is in another place. Are you sure that the code that should display the MessageBox is executed?
EDIT: When you develop web applications (ASP.NET), as described by you in comments, you cannot use Winforms MessageBox.
Try showing it with javascript, if you really need it
Response.Write("<script>alert('This a message')</script>");
Am I correct in understanding that the Method LiveDataContext.SignIn can only be used in Windows Applications?
Reference:
http://msdn.microsoft.com/en-us/library/ff747817.aspx
I tried to implement it in ASP.NET but get an error that I cannot use Modal Windows. So it seems to me that SignIn uses the Windows.Forms.
Thanks for your time.
It's pretty independent of mvc or webforms I think.

I developed an ASP.NET web application that reads an MS Access database with ADO.NET. This application will have to be run on Linux with Mono. Unfortunately, I am having problems getting Mono to work with the ADO.NET database connection.
With the connection string enabled on an onLoad event, the web app will not render; however, when I delete the onLoad event, the web app renders in the browser. I verified that it wasn't just the onLoad event as the problem by pressing a button that has an onClick event that reads the Access database, as well. The problem then persists, which is the following error: System.DllNotFoundException: gda-2...
I did some research on this error and downloaded the library libgda, but this did not fix the problem. Now I am seeing posts that Mono doesn't work with MS Access driven ASP.NET web applications.
Has anyone been able to get an MS Access driven ASP.NET web Application to work with Mono? If so, what steps did you take to get it to work?
I really appreciate everyones feedback, and if anyone has any suggestions, I would really be greatfull.
Thank you,
DFM
I do not think that MS Access will work with mono, because it depends on the MS JET database engine which is not a part of the .NET framework itself, but a windows component.
That said, developing a web application that accesses an Access database is not a very good idea. Access is a desktop application, and not scalable for web application usage.
I would recommend that you find an alternative database engine, such as MySQL (since the application should run on Linux)
