What features should Java 7 onwards have to encourage switching from C#? -

C # There is a good speed at this time. What features do you have to switch (or return) Java?

This will also be useful if people are able to add existing Java versions, such as custom The sections are wrapping around, to make it more interesting wiki.

A .net / C # developer here is missing features that are disturbing me in no particular order This is not a list - as soon as ideas get noticed:

  1. The Java Library is very small For normal things, I have to choose between 5 competing open source products because there are many types of deficiencies in the base library. is.
  2. Is this an object-oriented programming language? Why not the primitive types arising out of "objects" in heck?
  3. Symbols
  4. Closer
  5. Partial Classes and One Low Partial Methods
  6. Real for Generics Support
  7. Using and Setting Out Answers - It was a real WTF for me You really have to close the connections in the effort / catching block explicitly poor Java friends!
  8. Good
  9. Unusual Integer - Then WTF? Again, for what purpose do I need to use more than enough numbers?
  10. In Java, you can return from the last block of the try / catch. A colleague should start a bug like this, for hours I confused hell out of this behavior, as this behavior should be restricted to C # .

I rarely have to use Java and when I do, I have all kinds of WTF moments.

Edit: Based on this fact, for every comment it is no longer a missing Java feature since 1.5.

asp.net - Javascript/DOM Why is does my form not support submit()? -

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

sockets - Delphi: TTcpServer, connection reset when reading -

I am trying to implement one for Delphi, but there are some problems with communication. Fitnesse will start my process, and give me a portmember as a command line argument. Then I should make a socket on the port number given to me, and fitness will connect to that port I am using a TCPCP server for the job: < Pre> TcpServer1.LocalPort: = ParamStr (ParamCount); TcpServer1 Active: = true; On OnEXEPT () -Event, I send the protocol version to use as specified in the protocol. Process TForm1.TcpServer1Accept (From: TOBject; ClientSocket: TCustomIpClient); Var s: ansistring; Start clientSocket. Syndrome ('slim - v 0.0', # 10); SetLength (S, 6); ClientSketts Receavebook (S, 6); End; When I call ReceiveBuf (), the process ends, and fitness throws an exception: java.net.SocketException: connection Reset I have seen what sent and received. It shows that my code sends the protocol version, fitness sends back a message, and when I try to get this message

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
