Re: Network - C# Discussion Boards

\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)

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?

Hello
yesterday i have asked a question for a connection between a client and a server using a c# application,and that client should send a file to the server.
Someone tell me to use the tcp/ip.
But the client and the server are connected only trough internet.So does this tcp/ip run,Do someone have some other idea??
best regards

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.

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 ?

I am using visual studio 2003. My application is a window application and i am using C#. I want to put double click event for each row in the datagrid.

Can anyone help me please.

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.

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!

correct

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.

Hi.

I wanted to remove Vista security notification balloon that pops up when you deactivate UAC (User access control).

I need to do this in an application written in C#, I can easily do this in a cmd, but it does not seem to work in C#.

I write this in the CMD:

REG DELETE "HKCR\CLSID\{FD6905CE-952F-41F1-9A6F-135D9C6622CC}" /f

So I created this C# code:

CreateProcess("reg.exe", @"DELETE \"HKCR\CLSID\{FD6905CE-952F-41F1-9A6F-135D9C6622CC}\" /f");

Create process creates a new process with reg.exe as an application and the delete as argument.

That does not work. Any ideas?

Yeah, try writing some code that accesses the registry directly instead of trying to duplicate your command line code.
