How to import a config file into Core FTP LE

Backgrounder - Why Core FTP is a default for CPANEL

Core FTP is a default for CPANEL because it proper implementation for secure file transfer methods like SFTP (SSH File Transfer Protocol) or FTPS (FTP over SSL/TLS). 

SFTP is an FTP protocol that runs on top of a the SSH (Secure SHell) protocol, while SSL/TLS refers to standard FTP running over a SSL (Secure Sockets Layer) connection. There is some confusion about what SFTP is when some organizations are incorrectly using the term. They are referring to SFTP as Secure FTP, when it is actually standard FTP running over an SSL connection, and not actual SFTP. Chances are, if you are new to secure FTP, you are most likely using SSL, and not SFTP. While they are similar in terms of secure connections, they are completely different protocols. If you can't get your secure FTP connection to work, make sure SSH is unchecked, and SSL is checked when connecting to secure FTP servers.

Here's how to import a config file (.coreftp) that you download from CPanel into Core FTP LE

There is no function to import under the top menu. It's not under File, etc.

You have open the Site Manage located under top level Sites menu. In Site Manager windows, right-click into blank area (saved sites window) to reveal import capability. 

1. Click Sites⇀Site Manager. 
2. Right-click the main blank window and click Import⇀Core FTP.

You might want to change font size as well. Here's how to do that.

Personally, I find Core FTP the annoying because of a very un-intuitive design and ridiculously small fonts. Core FTP is freeware but has no publicly available source code.

Outlook desktop app account settings for Hotmail.com broken and have been updated

As of  November 17, 2020 my Outlook desktop app client started to have authentication problems for my hotmail.com / outlook.com emails and I though initial it was due to outdated setting see below. But that was not it.

Seems my VPN is randomly choosing countries on start-up to pass thru even though I selected Canada only by default. However, if you are connecting from different countries or IP addresses (if you are a mobile worker for example) you will like trigger the following warning.

Update 11-Feb-21 - How to check Outlook desktop app account connection problems with Outlook.com or Hotmail.com blocked, stopped, not working, authentication problems

outlook.office365.com is complaining of suspicious activity and has temporarily blocked access.  

Solution : Login into outlook.com with hotmail.com or outlook.com through your browser into your account will work in your Outlook client. 

Double check these new server settings as well. 

There are new server settings, and available here for reference :  https://support.microsoft.com/en-us/office/pop-and-imap-email-settings-for-outlook-8361e398-8af4-4e97-b147-6c6c4ac95353

POP Server: outlook.office365.com Port: 995 Encryption: SSL/TLS

SMTP Server: smtp.office365.com Port: 587 Encryption: STARTTLS

Goto E-mail accounts and edit your existing connection to use the above setting, below is for POP/SMTP settings. Change to new setting in above table

C# .NET How to get the literal .NET string, the internal storage representation of a C# string

From my last post we were dealing with the are gotcha's introduced when processing null character ('\0') which you might incorrectly deduce is a white-space character.

But in fact, in C# '\u0000' is a null character, but has no special meaning in C#. It just a null character in a string. It is considered not white-space but a control character. It's not considered a null either or string terminator as it is in C. To view control characters in VS Code, see my blog post and in Notepad++ see post.

In fact, you can look a the .NET internal storage of a string using the following code, and it rather expensive and slow to do. But in case you need it, especially when dealing with registry values that are riddled with '\0' you need it. 

  
Source Code

using System;
using System.Diagnostics;
using System.IO; 
using System.CodeDom;
using System.CodeDom.Compiler; 
					
public static class Program
{
	public static string ToLiteral(this string input)
	{
		using (var writer = new StringWriter())
		{
			using (var provider = CodeDomProvider.CreateProvider("CSharp"))
			{
				provider.GenerateCodeFromExpression(new CodePrimitiveExpression(input), writer, null);

				return writer.ToString();
			}
		}
	}

	public static void Main()
	{
		 Stopwatch sw = new Stopwatch();

            string emptytest = "1 \0 \0 \u0001 \0 \0\r\n\tSOS\n1 0 0 1 0 0 1\r\nIn distress\r\n1 0 0 1 0 0 1\r\nUnicode \\u0081 on the next line\n\n\u0081";
            sw.Start();
            string output = emptytest.ToLiteral(); 
            sw.Stop();
		
        Console.WriteLine(emptytest);    
		Console.WriteLine("---- Literal -----");    
		Console.WriteLine(output + " in " + sw.ElapsedTicks + " ticks");

	}
}

C# .NET How to remove blank lines from a string faster, dealing with null '\0' character confusion

Typically, in C# code you would use a 

str.Split(TrimNewLineChars, StringSplitOptions.RemoveEmptyEntries);

to remove empty white-space lines and is effective. But a faster way is to use StringReader and process each line. 

But there are gotcha's introduced when processing null character ('\0') which you might deduce from the above to be a white-space character. But in fact, in C# '\u0000' is a null character, but has no special meaning in C#. It just a null character in a string. It is considered not white-space but a control character. It's not considered a null either or string terminator as it is in C. To view control characters in VS Code, see my blog post and in Notepad++ see post.

In fact, you can look a the .NET internal storage of a string using, see my next post on this.

using (var writer = new StringWriter())
{
    using (var provider = CodeDomProvider.CreateProvider("CSharp"))
    {
        provider.GenerateCodeFromExpression(new CodePrimitiveExpression(input), writer, null);

        return writer.ToString();
    }
}

TLDR / Lesson Learning :

Counter-intuitively StringSplitOptions.RemoveEmptyEntries considers null character ('\0') whitespace, not a control character.
