What does it mean for a ChannelFactory to have a State property? I understand that a created channel can have connection based states. But am confused as to why the ChannelFactory also has such connection states. Does it too connect to the WCF service? ...
Recently I got a comment to this answer that I should stay away from java.io if I want to use "pure NIO". This is the simplified code (copy a file): private static void copy(File source, File destination) throws IOException { long length = source.length(); FileChannel input = new FileInputStream(source).getChannel(); FileCha...
We have developed a custom WCF channel which communicates via IBM Websphere MQ. We have created a channel factory: public class MqChannelFactory : ChannelFactoryBase<IRequestChannel> Which returns instances of our channel: public class MqRequestChannel : ChannelBase, IRequestChannel Connecting to the IBM MQ queue manager is an ex...
I've read here: Error 10048 when trying to open TcpChannel I am having what I thought to be a similar problem - apparently not. I took the advice of the first respondant to reset winsock (how does the winsock get corrupted, anyhow?) Anyway, here is my channel registration: channel = new TcpChannel(channelPort); ChannelServices.Regist...
I am trying to get a Client IP address & port for an internal collection. I found this answer. However, this seems like a lot more than what I need to simply grab the client's IP address & port. Are there any other ways to do this? ...
Can you use a token defined in the lexer in a hidden channel in a single rule of the parser as if it were a normal token? The generated code is Java... thanks ...
It seems to me that since Facebook is removing all application to user notifications(except facebook developed applications) that the application economy is going to become stagnate. How does it make sense to make all application to user communication be through proxy email or through a games dashboard that people have to bookmark your ...
Hello As the title implies I am trying to get an understanding of why in WCF sometimes people choose to "generate proxies" vs using a ChannelFactory to manually create new channel instances. I have seen examples of each, but haven't really found any explainations of WHY you would go for one vs the other. To be honest I have only ever w...
Hello. Is there a way I can determine if an HDC uses alpha channel? I read Question 333559 and Question 685684, but their questions are about BITMAP. Apparently, some HDC has alpha channel (though they may not use it. Call this "Type 1") while others do not ("Type 2"). I know this by doing the following: Given a HDC, Create a compatib...
Hi there. I am at a loss here after searching around with no results. I am attempting to channel the audio specifically from an .mp4 for use in a driver. I am aware that there are programs which extract the audio from .mp4's, but I am looking for another approach without using external applications such as those.. is there any directi...
I have a Flash app with a PHP backend. Whenever there is a PHP error, I get the "Channel Disconnected before an acknowledgement was received" error message. I'm getting ready to push my project to beta and I would prefer if this message said something more like "There was a PHP error, please log a bug" or something instead of a message ...
I have a web tier that forwards calls onto an application tier. The web tier uses a shared, cached channel to do so. The application tier services in question are stateless and have concurrency enabled. But they are not being called concurrently. If I alter the web tier to create a new channel on every call, then I do get concurrent ca...

Hello, is there a conceptual difference between the terms "Channel" and "Stream"? Do the terms require/determine, for example, the allowed number of concurrent Consumers or Producers? I'm currently developing a Channel/Stream of DataFlowVariables, which may be written by one producer and read by one consumer as the implementation is de...
hi I am trying to create two IPC channels IpcChannel ipcChannel = new IpcChannel("DroolsClient"); ChannelServices.RegisterChannel(ipcChannel, false); objec = (DroolsInterface.RulesEngineInterface)Activator.GetObject(typeof(DroolsInterface.RulesEngineInterface), "ipc://Drools/SreeniRemoteObj"); IpcChannel ipcChannel2 = new IpcChannel(...
Hello, I just wrote some NIO-code and wonder how to stress-test my implementation regarding SocketChannel.write(ByteBuffer) not able to write the whole byte-buffer SocketChannel.read(ByteBuffer) reading the data in chunks into ByteBuffer are there some simple linux-utilities like telnet to open a ServerSocket with some buffering-op...
How can I create a custom channel in WCF that sends its own messages. These messages should be handled by the same channel on the service side and should not get to the EndpointDispatcher. I believe that Reliable sessions binding elements uses something similar for its keep-alive functionality. ...
Hi. I am relatively new to iPad programming in cocoa touch. I have a PNG with an alpha channel. I want to overlay it as a subview on a UIButton so that it looks as though the Button has a border around it. (Alpha channel is the centre of the image so the user must still see through it). I can't seem to find a way to display the alpha c...
