OK,I have being a WebServer,
client is IE or Firefox
WebServer suppost http 1.0
when Client connect to server http://192.168.1.15/Nhat.txt,then Sever will do:

+create socket to transfer file to client
if Nhat.txt is not Exist then transfer to client "Http /1.1 404"

is the 404 being automatically generated by the framework, or by custom code you wrote. IF the latter post the code generating the 404.

Why on God's Green Earth are you using Sockets for this???!!!

Use the http classes in the .Net framework and save yourself a lot of headaches. This isn't even worth discussing if you want to use sockets.

HTML Parsing question

Im using iTextSharp to create a PDF. We're passing in several chunks of HTML to compose the display however iTextSharp's HTML to PDF parser just cant handle nested DIV elements with a horizontal alignment different from its parent. For instance:

[code]
<DIV align=center>
<u>
<DIV align=right>
TestRight
</DIV>
</u>
TestCenter2
</DIV>
[/code]

Will be displayed: TestRight and TestCenter2 both being centered. It just ignores the align right whereas the web browser does it correctly.

Unfortunately the itextSharp parser is too complex looking for me so I've opted to modify the original HTML string before passing it into the parser. Basically i was hoping for some code to move all child aligned chunks to the top level. But maintaining the original text formatting and text placement (ie. TestRight comes before TestCenter2) made my solutioon overly complex.

Anyone have a simple solution?

Im using ASP.NET & C# but I'm open to any source code solutoon.

Ouch, yeah that's a lot more clear than what you said before... I haven't worked with iTextSharp, but in my experience, things that claim to create PDFs out of other documents never work right. When I had to create a PDF on-the-fly for my previous company, I used XSL-FO and a Java servlet called Apache FOP. It's pretty good, but you can't just convert a document, you have manually write the XSL-FO file, and it's pretty tricky. The work is worth it though, because you can create very nice looking PDFs, and you can insert data if you want, although it does have to be inserted into the XSL-FO file before passing to the PDF engine.

http://xmlgraphics.apache.org/fop/[^]

The C# ASP.Net engine can connect to this with a standard http call, so you can pass the resulting files through and the user never knows that you temporarily went over to an Apache server.

FTP Upload, problem to close stream

wojti4-Jun-07 6:05

Hi,

I have a method to upload file using FTP.

By uploading to the one of the FTP server I have a problem by closing stream.

The file is uploaded successfully but when I try to close stream, then my application hangs up.

This is in line: strm.Close();

On some other FTP server everything works fine. Could be it a problem with FTP server? I gewt this error only by working with larger files.

How schould I solve it? Is it allways neccessary to close the stream?

Thanks

Wojtek

Bellow my upload method

Stream strm = null;

FileStream fs = null;

try

{

DirectoryInfo dirInfo = new DirectoryInfo(source);

//upload all archive file from source directory

foreach (FileInfo fileInfo in dirInfo.GetFiles("*.rar"))

{

// get the object used to communicate with the server

FtpWebRequest request = (FtpWebRequest)WebRequest.Create(new Uri(string.Concat(hostName, "/", fileInfo.Name)));

//set ftp method

request.Method = WebRequestMethods.Ftp.UploadFile;

request.UseBinary = true;

request.Timeout = timeout * 1000;

request.UsePassive = true;

// set credentials

request.Credentials = new NetworkCredential(userName, password);

// the buffer size is set to 2kb

int buffLength = 2048;

byte[] buff = new byte[buffLength];

int contentLen;

// opens a file stream (System.IO.FileStream) to read the file to be uploaded

fs = fileInfo.OpenRead();

// stream to which the file to be upload is written

strm = request.GetRequestStream();

strm.ReadTimeout = 5000;

// read from the file stream 2kb at a time

contentLen = fs.Read(buff, 0, buffLength);

// till Stream content ends

while (contentLen != 0)

{

// write Content from the file stream to the FTP Upload Stream

strm.Write(buff, 0, contentLen);

contentLen = fs.Read(buff, 0, buffLength);

}

}

}

catch (WebException e)

{

output.AppendLine(e.Message);

}

catch (InvalidOperationException e)

{

output.AppendLine(e.Message);

}

catch (Exception e)

{

output.AppendLine(e.Message);

}

finally

{

// close the file stream

fs.Close();

strm.Close();

hi well i have written a code to connect to remote machine and stop a particular service so that i could delete its log file.I am able to connect to remote machine and stop the service but i am not getting the exact command to delete the log file.
Pls look at the code below...

<br />
using System.Management; <br />
----- <br />
               connOptions = new ConnectionOptions(); <br />
               connOptions.Impersonation = ImpersonationLevel.Impersonate; <br />
               connOptions.EnablePrivileges = true; <br />
               myScope = new ManagementScope("\\\\" + SelectedComputer + "\\ROOT\\CIMV2", connOptions); <br />
               object[] arrParams ={ "Del /q C:\\WINDOWS\\system32\\CCM\\Logs\\execmgr.log" }; //net stop ccmexec //net start ccmexec<br />
               try <br />
               { <br />
                   manageClass =new ManagementClass(myScope, new ManagementPath("Win32_Process"), new ObjectGetOptions()); <br />
                   manageClass.InvokeMethod("Create", arrParams); <br />
<br />
               } <br />
               catch <br />
               { <br />
                   MessageBox.Show("Access Denied or System couldn't be contacted!"); <br />
               } <br />

If you ll look at this particular line

<br />
object[] arrParams ={ "Del /q C:\\WINDOWS\\system32\\CCM\\Logs\\execmgr.log" }; //net stop ccmexec //net start ccmexec<br />

I am trying to delete this log like via this command but it isnt working where as i can start and stop the service of the remote machine via "net start ccmexec" and "net stop ccmexec"

I have tried this in local machine aswell and i am unable to delete the file..I guess there is something to do with delete command...????

Could anyone please shed some light over it...

Thanks a lot

I am currently working in Visual C# Express 2005, and I have been doing all my unit testing using forms in a seperate project in my solution. I am wondering if it is possible to use nUnit in C# express, as my project manager has told me this is not possible. Has any gotten nUnit to work with C# express?

One way to do this to override the base class serilization with your one implementation. By this you can very well use the default serilization dataset and then for the two class objects call the serilisation method implemented for their class.
