C# - Sending A String With Sockets?
Aug 20, 2009I am using Nektra's Deviare to hook winsock's send method calls. My ideia is to learn to also send messages through the same socket than the original application. So what I'm doing is when i detect the first call to send message, I save the socket id(the first argument of the send function), so I can use it later.
So here is my code:
uint socket = 0;
[DllImport("Ws2_32.dll")]
private static extern int send(uint socket, string buf, int len, int flags);

This last messagebox is poping up always -1. Why should be it?
edit: calling WSAGetLastError() returns 2. Which I do not know what it means, as it doesn't seem to appear on msdn.

Asp.net - Export To Excel File As .zip To Reduce File Size - Compress Xmldata Before Sending It To The Client?
Jul 8, 2010I like to compress the xmldata before the data is provided to the client as an excel file. I am trying to compress and deliver it as a .zip file. its not working Here's my code below. I tried compressing it, converting it to bytes etc etc. The issue with below code is, the XSL transformation is not happening properly and the output excel file is raw xml with some .net exception at the end. (that's what I see on the .xls file that's downloaded at the end) Before I started working on compression my below code was working fine that gives properly formatted excel file from the xml input. the excel file is so nice you can't even tell it was from XML.

Aug 5, 2009I need to send a switches and a filename to a command line application.First I'll need to get a collection of files that can range from 0 to an infinite amount.Then I can start the process with the correct switches. Normally, within the command line application, I would specify the specific filename and send it as an argument to the application.However, I'm not sure how I would do this. The names of the files have to be preceeded by a specific switch. I can't remember the switch right now, but we'll call it [b]-f[/f].[code]So, I need to figure out how to send all or each of the file names as an argument.

Oct 19, 2011I've implemented with Visual Basic 10 an application for Net Framework 4 with functionality to send files via e-mail using System.Net.Mail. It works well except when it comes to sending an XML file whose name contains accents. In the latter case the UTF-8 name is not correct, so Widows Mail Life presents him with name consisting of a set of meaningless characters. Furthermore, the content has lost the format of lines and spaces, presented part of MIME type information in the header, so that it is unreadable XML readers.

The issue I have with this is that the file size is _500KB. However save the file on my machine and it is around 370KB.
This increase in file size is unacceptable. has anyone come across this issue before? If so how have they got round the problem.

.net - Working Of Tcpclient Sockets In .net?
Jun 2, 2011I have an application in vb.net which will connect with an hardware device and test its functionality. The hardware device basically spits out data continuosly through Ethernet. That is it recieves some data via com ports and spits out the processed data via ethernet.So my application does both. Thats pretty much the entire app.My problem is i am using tcpclient sockets. Now when i connect a tcpclient to the device using
tcpclient.open(ip,port);
Immediately the device sends some data which comes and get stored in the clientsocket. Then i send a command to it ,only then i read the data from the clientsocket using
tcpclient.getstream().read()
at this time the entire data that is the one which flowed immediately when connected to the device and the one that i actually need after passing command is both acquired. This is undesirable. I need the data which i read only after sending the command. So i was wondering if there is any way to clear the tcpclient socket before we do a read. The manual doesnt show any such method.
