I use SslStream with TcpClient in following way: I call BeginRead() method and waiting for its results. When results come, I read them, call BeginRead() again and so on... Sometimes I need create another SslStream with this TcpClient, i.e. perform another ssl handshake. How can I abort reading execution? It seams that if I try to cal...

I am performing an http web request which asynchronously gets a response from the server. I wish to perform actions on the result directly and do not wish to have any code running in the meanwhile. The reason it has to be asynchronous is that I am writing a silverlight application. Here is a code snippet { .... request.BeginGetRespons...

Hi there, Can anybody advice me the best practice for closing WCF clients after doing a async calls? Should it be within the "completed" method or should there be a different approach? /BB ...
How do I create a unit test to test a class that sits in a loop? Here's the scenario. I have a class that is injected with a reference to a serial port. The class has a method called Send(String data); This public method invokes an aysnchronous private method to do the actual work. The class under test (CUT) should do the following ...
I'm putting together a series of web parts for a Sharepoint 2010 deployment - a few upgrades (from 2007) as well as a few new ones. I'm attempting to develop all the parts to perform data access server-side via a WCF service (namely, WCF RIA Services in this case). Basic synchronous databinding works great (for example): SomeGrid.DataSo...
VB.NET 2010, .NET 4 Hello, I have been using a pretty slick generic invoke method for UI updating from background threads. I forget where I copied it from (converted it to VB.NET from C#), but here it is: Public Sub InvokeControl(Of T As Control)(ByVal Control As t, ByVal Action As Action(Of t)) If Control.InvokeRequired Then ...
For the last week I've been trying to create an async method. I tried the MSDN article How to: Implement a Component That Supports the Event-based Asynchronous Pattern but it does the work in a method in the same class. The work I'm doing is a lot more complicated and is its own class. The problem I'm having is the class doing the work ...
public string CreateOrder(string purchaseOrder) { using (MyWebService.CreateService service = new MyWebService.CreateService()) { string orderCode = service.CreateOrder(purchaseOrder); return orderCode; } } I've added a web service reference to the domain layer of an ASP.NET web app. This generates the two...

I have AsyncPostBackTimeout set to a very large value (3600 = 1 hour). This should cause Ajax request in my .net app (Asp.net 3.5) to continue for an hour before expiring. However, for some reason, they are expiring after approximately 5 minutes (the request continues to execute on the server without any issues). What could be causing t...
I have a desktop application communicating with a WCF service that I have implemented. The desktop client does not use a generated proxy (Add Service Reference or SvcUtil) rather it uses a channel factory with a reference to the WCF Service contract assembly (the contract assmebly is separate to the implementation). I now need to provide...

I ask here since googling leads you on a merry trip around archives with no hint as to what the current state is. If you go by Google, it seems that async IO was all the rage in 2001 to 2003, and by 2006 some stuff like epoll and libaio was turning up; kevent appeared but seems to have disappeared, and as far as I can tell, there is sti...
I have the following (simplified) asynchronous method: void Transform<X,Y>(X x, Action<Y> resultCallback) {...} and what I want to do is transform a list of Xs into a list of Ys. The problem is that even though the Transform method is asynchronous, it has to be called serially (i.e. I have to wait for the callback before calling it w...
