| microsoft.public.dotnet.framework.clr |
| Folks, I have a problem that I can't seem to solve... I have two classes... Account and CreditAccount. CreditAccount extends Account. At runtime, I have two instances. One instance is an Account and the other is either Account or CreditAccount. An error condition would be when the second instance is neither of these types. I need to test whether the instance I have is in the Account taxonomy. I ha... |

| When is managed code not sufficient? (6 replies) |
| microsoft.public.dotnet.framework.clr |
| Targeting managed code makes sense for a very large number classes of applications. However, I am wondering if anyone is maintaining a list of exceptions to this, where for a either unmanaged or older compilers are used to solve current and relatively common problems. Just to drive the point home as to what I'm getting ati, I'll provide some examples. Albeit an obscure one is, Netscape PlugIns. If... |

| .NET advantages over native C++ (13 replies) |
| microsoft.public.dotnet.framework.clr |
| I have been using C for 10 years. Now I am trying to learn .NET. I still cannot understand and see a single advantage of .NET and C# as one of its core programming language over C Windows programming using high performance libraries like ATL (ATL Server), STL, WTL and even MFC. At the same time disadvantages are clearly seen: IL code must be JIT compiled before executing that hits performance, man... |

| Custom Http Server using TcpClient (how to obtain WebRequest / WebResponse) (2 replies) |

All of the examples that I have seen so far are overly complicated (i.e., You have to manualy read and write headers, data, etc. from the network stream). There should be some way to generate WebRequest and WebResponse (or HttpWebRequest and HttpWebResponse) objects on the server side once a socket connection is accepted. Given the following server side... |
