• Visual C# Getting error while converting byte to ushort

  Hi, I wrote a simple program to check the implicit conversion. I was under impression that I should be able to convert byte to short or ushort. But when I compile following program I get an error saying - error CS0266: Cannot implicitly convert type 'int' to 'ushort'. An explicit conversion exists (are you missing a cast ) Can someone tell me what am I doing wrong here Thanks, green using System; public class Demos { public static void Main() { byte b2 = 125; byte b3 = 200; ushort i = b2 + b3; Console.WriteLine(i); } } As far as i can remember, in addition all the operands are implicitly converted to a single type int(or an another type which i can't recollect).

• .NET Development WinForms app and socket connection

  Hi, I would like to get your opinion on this: I have WinForms app and at the main form I'm opening a socket connection to the server. This connection should stay open until the user closes the app. What's the best way to share the same socket with other forms that may opened from the main form A global variable at the main form will be a good idea Thanks. Ubercoder If you only ever want to have a single socket then statics are an option. Depending on your requirements I suggest looking into 3-tiered architectures (a heavy weight solution) or possibly a simple implementation the fascade pattern to decouple your logic from your UI. ...Show All

• .NET Development .NET vs Trolltech's QT

  Why should my company choose .NET over Trolltech's QT plattform Qt can be seen as a third-party contributor w/ C++ libraries. There is no problem adding Qt's libraries to be used in a .NET environment. I like Qt because it is very powerful and well documented libraries, similar to STL libraries but much more extensive. Qt is free if you develop Open Source,. and for a fee if you develop for Commercial use. I recommend you to test it yourself under the Open Source license and if you like it your company can buy it. I think it is NOT an alternative .NET more like a complement since .NET is a development environment in itself while Qt is not ...Show All

• Visual Studio Express Editions HowTo: Startup Application Invisible in the System Tray

  The standard method for starting up an application invisible is to use the Sub Main() as the startup object, then load the form as necessary. However, if you want to use the application framework, this option isn't available. I've been wrestling with this problem for some time, and have several solutions, none of which are adequate. But what follows seems to be the best solution, but first, the 'broken kludge': One option was to have the form completely opaque, and set the ShowInTaskBar to false. Once the form has loaded, set the visibility to false, restore the ShowInTaskBarback to True, and set the opacity to that which is desired. There are two problems with this: 1. It requires an 'event' after the form has loaded to reset ...Show All
