Hi, i have wrote a code to connect to FTP. But once connected, a DISCONNECT button will show. And when i click it, i wan it to end the connection.
CONNECT CODE
public bool Connect()
{
bool success = false;
try
{
reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + tbxServerAddress.Text + "/"));
reqFTP.UseBinary = true;
reqFTP.Credentials = new NetworkCredential(tbxUsername.Text, tbxPassword.Text);
reqFTP.Method = WebRequestMethods.Ftp.PrintWorkingDirectory;
WebResponse response = reqFTP.GetResponse();
if (response !=null)
{
success = true;
}
else
{
success = false;
}
}
catch (Exception ex)
{
MessageBox.Show("Error : Invalid User or Pass");
}
return success;
}
Btw am i coding the connect code the right way?
And how do i code the DISCONNECT method
|

It doesnt have the finalize method
btw when i upload a file, how do i use the current connection to upload instead of creating a new connection
|
|
|
|
|
|
but i cant use it.. it says
Finalize is protected and, therefore, is accessible only through this class or a derived class.

You can send the "close" command to the ftp server to quit the connection, or close the stream AFAIK.

Hi,
Can you tell me to develop Smart Card Application in C#.

Since the var keyword has been introduced for anonymous types I have noticed more and more code examples (and seen in my work) people using var rather than a defined type.
To my mind var should only be used when an anonymous type is being used and only then not instead of a defined type.
What are peoples thoughts? are you seeing a rise in the use of var?

If you give a novice programmer something to abuse, they will abuse it. Its about the first rule of computer programming.
The only place I have used var so far is in the return from a LINQ query, I see no reason to use it extensively. So in short, I agree with you.

I absolutely agree with you.
As I see it, every developer must be aware what he/she is doing. He has to know about the types etc. he is using etc. Using a paradigma like "Uh I don't know what the return type of this method is, but hey who cares, the compiler will do it for me" is not the way I agree with.
So in my opinion the excessive use of "var" makes the code difficult to read, you always have to search for the last assignment...
As far as I know, var was introduced only for the use with LINQ, but as you already said, it will be abused...
Regards
Sebastian
P.S.: Had a big discussion here last week, if we should use it throughout the code or not...

What has been worrying me is more senior experienced programmers starting to do it.
Brought back horrible memories of VB6 variant <shudder>

I know! Well, they've got it wrong. I hate the use of this subversive keyword. Fair dos for LINQ but no place elsewhere. Presumably you can tell Resharper not to do that, but I can't be bothered to wade through all the options pages. It does alsorts of things I don't care for - breaking my lines up, trying to use 'object initializers' to squeeze everything onto the construction line, putting space between casts etc.
It should chill out a bit.

Since you're asking for opinions, here's mine.
I would not be opposed to seeing var when you are declaring a new something (especially when the type name is long). For example:
var cache = new Dictionary<string, LongTypeNameIWantToTypeJustOnce>();
as opposed to
Dictionary<string, LongTypeNameIWantToTypeJustOnce> cache = new Dictionary<string, LongTypeNameIWantToTypeJustOnce>();
which I either have to break up into multiple lines or have one really long line. Even if the line is not too long, the second way is still noisier than the first.
For the record, this is one of the things I like about the VB syntax (only needing to write the type once when declaring and "new"-ing a variable at the same time)

I agree, it is being abused. I never use var, and as I also never use Linq, I don't expect to.

I just use an XmlDocument.
I was doing some more XSL last night. Maybe you have a Linq way of doing this...
In my XML file I have a processing instruction to indicate the XSL file and stylesheet to use:
<?xml-stylesheet type="text/xsl" href="mystylesheets.xsl#somestylesheet"?>
Unfortunately, those aren't Attributes, they are in the Value! I've been using a Regular Expression to get this information:
private static readonly System.Text.RegularExpressions.Regex HrefReg =
new System.Text.RegularExpressions.Regex
(
"href\\s*=\\s*(?'quot'[\"'])(?'href'.*?)((?'sep'#)(?'id'.*?))?\\k'quot'"
) ;
Do you have a Linqish way to do that?

dtpFromDate & dtpTodate are DateTimepickers and a TextBox txtNoofDays
private void dtpFromDate_ValueChanged(object sender, eventArgs e)
{
double value=Convert.ToDouble(txtNoOfdays.Text);
dtpToDate.Value=dtpFromDate.Value.AddDays(value);
}
Here I got the error at--> //double value ----
Input string was not in correct format
How to resolve It.

The problem is in First statement
double value=Convert.ToDouble(txtNoOfdays.Text);
The Convert.ToDouble() function is not getting the correct input to convert. Like there can be nothing in the text box or there can be a space or any other character which is throwing error that the string is not in correct format.

I have to export the data displayed in the WebBrowser to Microsoft Excel. It is a window application using c#. Does anyone know how to do it. Please help.
Thanks

I have a measurement device that measure and sends a data update string to the PC once a millisecond, so you can see what's happening in real-time.
I would like to let authorized people see my data via the web in roughly real time using a web browser such as Internet explorer. I have an internet connection with valid IP address that whole of day it is connected.
My idea so far, is to divide the problem into originator (my PC putting data on database) and clients (pc's logging into my computer via web browser to see latest data).
Originator:
I thought I would use SQL database to save average measured data into the database every one seconds.
Clients:
This has to log in, see designed GUI, select charts, table and reports via menu.
I am very keen to hear any suggestions. I want to keep it in C#.
Does anyone know how I can do this?
With best regards,
