I would bet there is but why o why would you do that? The User is supposed to control the colors. WTF | :WTF:

If i had a chance, i would never, never give that kind of innesential flexibilities to the user. But i am just a developer in a company. So i am developing a program and its backcolor is black. Because a stupid client wants it black. Mad | :mad:

I changed the DataGridView's backcolor to black, but the scrollbars are still gray, and it looks very ugly. Client does not want this, so i am trying to change their color to black, but i didn't find a way yet, and i don't know even it is possible or not. Confused | :confused:

SFTP using FtpWebRequest class?

I am attempting to read an SFTP directory using the FtpWebRequest class, but am getting the error 'Unable to connect to the remote server'. Here is my code:

Private Sub List(ByVal listUrl As String, ByVal username As String, ByVal password As String)<br />
 Dim reader As StreamReader = Nothing<br />
 Dim listRequest As FtpWebRequest = WebRequest.Create(New System.Uri(listUrl))<br />
<br />
 System.Net.ServicePointManager.CertificatePolicy = New TrustAllCertificatePolicy<br />
 listRequest.Method = WebRequestMethods.Ftp.ListDirectoryDetails<br />
 listRequest.KeepAlive = True<br />
 listRequest.EnableSsl = True<br />
 listRequest.Credentials = New NetworkCredential(username, password)<br />
<br />
 Dim listResponse As FtpWebResponse = listRequest.GetResponse()<br />
 reader = New StreamReader(listResponse.GetResponseStream())<br />
End Sub<br />
<br />
Public Class TrustAllCertificatePolicy<br />
 Implements System.Net.ICertificatePolicy<br />
  Public Function CheckValidationResult(ByVal srvPoint As System.Net.ServicePoint, _<br />
            ByVal certificate As System.Security.Cryptography.X509Certificates.X509Certificate, _<br />
            ByVal request As System.Net.WebRequest, ByVal certificateProblem As Integer) As Boolean Implements System.Net.ICertificatePolicy.CheckValidationResult<br />
<br />
 Return True<br />
 End Function<br />
End Class<br />

I appreciate any advice you can provide into what I'm missing. Thank you,

Jason, you posted a VB.NET question in the C# forum. Smile | :)

Vb.net and c# are the same thing, more people visit this forum so I figure there is a better chance of getting an answer here.

Here is the C# version - I'm really not interested in getting into a C# is better then vb debate. I just want get this working so I can move on to the next item on my to do list.

private void List(string listUrl, string username, string password) <br />
{ <br />
 StreamReader reader = null; <br />
 FtpWebRequest listRequest = WebRequest.Create(new System.Uri(listUrl)); <br />
 System.Net.ServicePointManager.CertificatePolicy = new TrustAllCertificatePolicy(); <br />
 listRequest.Method = WebRequestMethods.Ftp.ListDirectoryDetails; <br />
 listRequest.KeepAlive = true; <br />
 listRequest.EnableSsl = true; <br />
 listRequest.Credentials = new NetworkCredential(username, password); <br />
 FtpWebResponse listResponse = listRequest.GetResponse(); <br />
 reader = new StreamReader(listResponse.GetResponseStream()); <br />
}<br />
 <br />
public class TrustAllCertificatePolicy : System.Net.ICertificatePolicy <br />
{ <br />
 public bool CheckValidationResult(System.Net.ServicePoint srvPoint, System.Security.Cryptography.X509Certificates.X509Certificate certificate, System.Net.WebRequest request, int certificateProblem) <br />
 { <br />
   return true; <br />
 } <br />
}

Are you sure the Server is running?

The server is running and I have no problem connecting with WS-FTP. I'm starting to wonder if FtpWebRequest works for SFTP. I have been reading some blogs and others are having the same problem but no one has a solution. Here are some links:

At this point I'm going to look into other ways to get this resolved.

C# Express returning on }

Yes this entry from that blog holds the key

Actually, .NET 2.0 does not currently support implicit SSL, only explicit.  We will consider adding this for a future release.

Visual c# express on Win XP x64

I wrote this part of the code:

<br />
for (int i = 1; i < 11; i++)<br />
{<br />
  for (int j = 1; j < 11; j++)<br />
  {<br />
    dataGridView1[i, j].Value = "0";<br />
  }<br />
}<br />

and the program seem to be returning form the method on the first } it encounters.
Debugging also shows that it starts doing the first for the goes to the 2nd one and when the 2nd one is finished it just drops out of the method.

but as for:

<br />
private int test()<br />
{<br />
  int g;<br />
  for (int i = 0; i < 9; i++)<br />
  {<br />
    g = 88;<br />
  }<br />
  g = 99;<br />
  return g;<br />
}<br />

99 is returned.

Any ideas what might be wrong?

The only reason that I could imagine for dropping out of a loop like that would be if the dataGridView1 did not contain 11 x 11 items so that you get an IndexOutOfRangeException exception, and that you have a try...catch somewhere that it will skip to.

Are the indices really one based, not zero based?

Thank you.
It was that I did not generate enough rows.

But it seems strange to me that the program did continue just normally as I don't have any Try/Catch statements.
It was in : private void Form1_Load(object sender, EventArgs e); If that may be the reason.

Thank you for the help Smile | :)

It can't continue just normally, as there was an exception. If you don't catch it anywhere it will just bubble up to the application level, where IIS will log it and create an error page for the user.
