| Asynchronous calls samples needed |
| microsoft.public.dotnet.languages.csharp |
| Hi, I'm trying to code a asynchronous call, and I've looked into MSDN for samples, but it looks like their documentation is way outdated. One of the samples doesn't compile because it tries to access the AsyncResult.AsyncDelegate method to get the delegate... but the AsyncResult class does not exist. The other sample tries using IAsyncResult.AsyncObject to do the same thing, but AsyncObject is not... |

| ASynchronous Functions |
| microsoft.public.dotnet.framework.aspnet |
| Hello, I am putting together a utility class for my ASP.NET web site and one of the methods is called "SendEmail" which, you guessed it, sends an e mail. But since sending an e mail could take awhile, I decided to use ASynchronous (multi threaded) programming to let the site run "faster" while sending the e mail in the background. But I am having difficulty getting this to work. I found an MSDN ar... |

| Asynchronous TCP socket connection... packets are in an undefined order |
| microsoft.public.dotnet.languages.csharp |

It works great except, when I receive packets that are larger than my receive buffer which then generate several EndReceive calls... these calls seem to be sometimes coming out of order. For example, the following is from my log file: Connection at 5/1/2004 11:39:14 AM SENT ZZZ:1:FMZZZ:ID1234:PWAAAA:VR100:\0 RCVD ZZZ... |

So when I get the results posted back to the static callback method I want to write them to a label on the web form. Can some one tell me t... |

To relate it to what I already know, Invoke looks like it can be used kind of like SendMessage() Win32 API and BeginInvoke/EndInvoke are (sort of) like PostMessage or the MFC PostThreadMessage. Here is my question. If I call BeginInvoke and do not maintain a reference to the returned IAsyncResult do I have to call EndInvoke. In other word... |

| BeginInvoke() on Multicast Delegate. |
| Develop.com's DOTNET List |
| I can see two logical ways that BeginInvoke() could work with multicast delagate. a) Queue a single item to the work queue that calls ALL the delegate in the list. OR b) For each delegate in the list, queue an item to the work queue. In the both case, I would expect EndInvoke() to block until all delegates have been called. I may be going blind in my old age, but I can not find anything in the doc... |
