Writing FTP Client using NIO - Don't get reply after "putting" file via control SocketChannel - Why?

MB
I am writing an FTP Client using the NIO packages because I want to
use the non-blocking functionality. I have done this successfully
except for the fact that after I "put" an image file to the FTP server
(Microsoft FTP server) I never get a valid response (226 Transer
Complete) from the FTP server when the file has finished writing. I
am using the FileChannel.Tra nsferTo method with a non-blocking
SocketChannel that is connected to the FTP server. I am writing the
image file in a data SocketChannel and expecting a reply from the
server on a control SocketChannel that I have set up. Does anyone
know why I am not getting a response from the FTP server? Because my
Socket Channels are non-blocking the TransferTo method returns write
away but the file actually takes up to a minute or two to actually
finish transferring. When I check the file size on the FTP server and
it finally looks like it should be finished, I am not getting a valid
FTP response in my program.

Thanks,
MB

I see some code examples like this: <DIV onmouseover="this.style.background='blue'"> and other code examples like this: <DIV onmouseover="javascript:this.style.background='blue'"> Which way is more proper? Or are both ways perfectly fine? Are there any specifications that discuss when "javascript:" should be put in front of code?

Hi, I have an aspx page where some controls are initially disabled by the code-behind 'Page_Load' event. I want these controls to be dynamically enabled when the user checks a checkbox. Because I don't want a post-back, I added some javascript to do this However, using client-side JS, I cannot enable any controls that have been disabled by server-side code. If the control is initially enabled, I can disable/enable it client-side.

Is it best to include the code "using namespace std;" in the source or should each keyword in the std namespace be qualified by the namespace tag, such as std::cout << "using std namespace" << std::endl; Myself I am not sure which I prefer, it is certainly easier to specify that the std namespace is being used instead of tagging each member of the namespace?
