message = requestStream.ReadToEnd();

Try:
message = new string(requestStream.ReadToEnd());

That should stop at the first \0.

Thanks leppie,

Your code is magic. What is the root cause of my original issue? And why your code can fix?

regards,
George

It was probably in the File/Resource you were reading. But because you need to read the whole file, ReadToEnd actually does not seem to stop at \0. This is probably by design.

My code fixes it as creating a string, will make sure it is only up to the first \0. After that, the rest is never considered.

To add: It is interesting that you found this. I have never come across it, but at least I am aware of it now (thanks).

Where in your code trims the string with ends \0?

\0 is the equivalent of null. Strings used to be null terminated but are not anymore (at least in .NET) however, the new String method is probably designed to stop reading on an null character in a string. I wonder, however, about the memory allocation. It is possible that the entire string is stored in memory, including the nulls but only the non-null portion is workable. (happens in C sometimes)

Thanks Ennis!

Does your reply answers why leppie's code trims endding \0?

I had a think about this. I suspect you are reading a binary file as a text file.

Thanks leppie!

I am reading from HttpListenerContext.Request.InputStream. Just send one XML file from a client, and my code read from another end.

1.

In this process, why do you think I experienced "reading a binary file as a text file", which causes \0 at the end?

2.

Do you have a scenario to reproduce this issue?

The ip part stands for 'internet protocol'. I guess you didn't bother to look it up.

If it were me, if the web were involved, I'd have a webservice on the server, and send using that.

when i create a service on the server, how can i connect to that web service from the client.
Note : there is not a web site or an ftp. I mean by a server a pc connected to the internet only( Smile | :)

).
So can i instanciate that service from the client.

Double click event in datagrid row in .net framework 1.1

23-Jun-08 23:55

If the two machines are just connected to the web and the server is not an actual server on the internet, then you probably want to go back to creating a TCP/IP connection. How does the client discover the server at all ?

If there isn't one, you can catch a single click, store the time it occured and on the next click see if they were close enough together to make a double click.

Hehe, so you get blamed for the lack of functionality. I sometimes wonder what goes through the minds of some characters.

I guess then page need to post back two times, right ? How about hooking JS double click event and raising postback manually ? I haven't tried it, but a wild guess.

BTW, don't know why you got down voted.

Aren't there data grids in winforms ? If this is an ASP.NET question, it's in the wrong forum.

*grin* It did occur to me that the question is ASP.NET, but I act dumb until it's clear, and assume the question is in the right forum.

what is the basic difference between evemts and function.
i know events execute a handler and function are user defined.
but unable to understad the difference

If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!

It's what you said. An event is something you can subscribe to, to be informed when something happens. The event will call functions, but most functions are not attached to events.
