You posted the same question yesterday
1) Why don't you want to use an IComparer? There is nothing wrong with it and it's the standard way to do sorting.
2) Post the error message you are getting.
Perhaps then someone will answer you.

FtpWebRequest reqFTP;
dirName = "/dir1//dir2//dir3";
reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + ip + "/" + dirName));
reqFTP.Method = WebRequestMethods.Ftp.MakeDirectory;
this.textBox_status.Text += WebRequestMethods.Ftp.ListDirectory;
reqFTP.UseBinary = true;
reqFTP.Credentials = new NetworkCredential(Username, Password);
FtpWebResponse response = (FtpWebResponse)reqFTP.GetResponse();
Stream ftpStream = response.GetResponseStream();
ftpStream.Close();
response.Close();
First, how to check the folder exist or not on the FTP?
The code can only create a directory in the path can we create multiple directory in the same time?
Thanks

I have problem with dll loading (windows says "Unable to load DLL 'Scilexer.dll', the spesified module could not be found. Exception from HRESULT : 0x8007007E).
this problem occurs when I try to override :
unsafe public override string Text
{
get
{
int sz = win32Access.SendSciMessage(directPointer,(int)ScintillaEnum.Selection.SciGetLength,0,0);
but when I change the name so that it no longer override, It can works. I can use this custom control again
unsafe public string TheText
{
get
{
int sz = win32Access.SendSciMessage(directPointer,(int)ScintillaEnum.Selection.SciGetLength,0,0);
please anyone help me to explain this.

Is Scilexer.dll is the same directory as the application? If so, are all Scilexer.dll's dependencies in the PATH?

Of course that dll's is in the same place. I copied that Dll into Debug and Release directory. That's why my Code work when I change unsafe public override string Text with unsafe public string TheText
Both can't work if the Dll is not in the right directory, right?
I'm still confused with this problem

What is the correct syntax to pass the value of index to the underlined code?
where in if index=2
XmlNodeList xmlNodes = xmlHelp.SelectNodes(string.Format("//Help[@name='{0}']/Item[2]", tag));
Below is my code:
protected void GetItemHelp(int index)
{
string tag = Request["ref"];
string sHelpFile = Server.MapPath("~/Help.xml");
try
{
XmlDocument xmlHelp = new XmlDocument();
xmlHelp.Load(sHelpFile);
XmlNodeList xmlNodes = xmlHelp.SelectNodes(string.Format("//Help[@name='{0}']/Item[1]", tag));
if (xmlNodes.Count > 0)
{
itemText.Text = xmlNodes[0].InnerXml;
}
else
{
itemText.Text = " [" + Server.HtmlEncode(tag) + "] Help is currently not available for this page.";
}
}
catch
{
itemText.Text = "Help is currently not available.";
throw;
}
}

XmlNodeList xmlNodes = xmlHelp.SelectNodes(string.Format("//Help[@name='{0}']/Item[{1}]", tag, index));

Hello Navaneeth
I tried doing that but it is giving me all the items in the list. It is not getting the 2nd item.
Based on the XML below, it will display Item1.
<HelpFile>
<Help name="name2">
<Item>
<p><strong>Item1</strong></p>
</Item>
<Item>
<p><strong>Item2</strong></p>
<Item>
</Help>
</HelpFile>
Because if I will simply write this, I can display Item2
xmlHelp.SelectNodes(string.Format("//Help[@name='{0}']/Item[2]
Any idea what am I missing?

Hello everyone,
I noticed in some code, in a derived class, the constructor will be written in a way like this, my question is whether it is good code to add base()? Because I think
- base() will be implicitly called for derived class constructor if we do not pass any parameters to base class;
- if we need to pass any parameters, I think we could declare in this way and pass parameter to base class in :base (parameters to base class constructor);
- so there is no need to declare in this way.
Any comments? Is my understanding correct?
DerivedClassConstructor():base()
{
}
thanks in advance,
George

When derived class is instantiated, base classes default constructor(parameterless one) will be called. If there is no default constructor available for base class, you should use base keyword to specify which base constructor has to be called. Not using base in this scenario will be a compile time error.
