vbCrLf Replacement

[JDYoder]

What is considered the .NET replacement of the above?

[Joe Mamma]

System.Environment.NewLine

[JDYoder]

Thanks much!

[JDYoder]

How about the replacement for vbTab?

[Bucky]

You could use ControlChars.Tab, but the ControlChars class is VB-specific and I wouldn't reccomend it. You can also use Convert.ToChar(9), since 9 is the Unicode value for a tab character.

[Joe Mamma]

As I can never remember the codes for keys, I like -

(char) Keys.Tab

 

or in either this will work, too:

Convert.ToChar(Keys.Tab)

 

Too bad "Keys.Tab.ToString()" doesn't return the tab character, eh?

 

hmmmm. . . . give me a moment. . . .

probably easier to do with CodeDom, but I have never used it. . .

 

to generate a class with usage:

char c = Unicode.Chars.Tab;
string c = Unicode.Chars.Tab.ToString();

 

executing this line:

Unicode.GenClass.Chars.GenClass();

on this class:

 

using System;

 

namespace Unicode.GenClass

{

 

public sealed class Chars

{

private Chars() {}

 

static void EnumProperty(string aKey)

{

 

object testKey = Enum.Parse(typeof(System.Windows.Forms.Keys), aKey);

if ( (Convert.ToInt32(testKey)> UInt16.MaxValue) | Convert.ToInt32(testKey) < 0) return;

Console.WriteLine("");

string keyName = aKey;

string keytype = string.Format("System.Windows.Forms.Keys.{0}", keyName);

Console.WriteLine(string.Format("\t\tstatic public char {0}", keyName));

Console.WriteLine("\t\t{");

Console.WriteLine("\t\t\tget");

Console.WriteLine("\t\t\t{");

Console.WriteLine(string.Format("\t\t\t\t return(char){0};", keytype));

Console.WriteLine("\t\t\t}");

Console.WriteLine("\t\t}");

}

 

public static void GenClass()

{

Console.WriteLine("using System;");

Console.WriteLine("");

Console.WriteLine("namespace Unicode");

Console.WriteLine("{");

Console.WriteLine("\tpublic sealed class Chars");

Console.WriteLine("\t{");

Console.WriteLine("");

Console.WriteLine("\t\tprivate Chars(){}");

foreach (string akey in Enum.GetNames(typeof(System.Windows.Forms.Keys)))

EnumProperty(akey);

Console.WriteLine("\t}");

Console.WriteLine("}");

}

}

}

I am sure the above would be easier and more elegant with CodeDOM, but I have never played with it. . .

[Joe Mamma]

the first handful of properties generated as the code is too long to post. . .

using System;
namespace Unicode
{
public sealed class Chars
{

 private Chars(){}

 static public char None
 {
  get
  {
   return(char)System.Windows.Forms.Keys.None;
  }
 }

 static public char LButton
 {
  get
  {
   return(char)System.Windows.Forms.Keys.LButton;
  }
 }

 static public char RButton
 {
  get
  {
   return(char)System.Windows.Forms.Keys.RButton;
  }
 }

 static public char Cancel
 {
  get
  {
   return(char)System.Windows.Forms.Keys.Cancel;
  }
 }

 static public char MButton
 {
  get
  {
   return(char)System.Windows.Forms.Keys.MButton;
  }
 }

 static public char XButton1

  get
  {
   return(char)System.Windows.Forms.Keys.XButton1;

   return(char)System.Windows.Forms.Keys.XButton2;
  }
 }

Thanks for all the help!

If everyone in your group agrees to it, you can just use "\t", as Joe sorta had embedded in one of his samples. I'd only do that if everyone knows and understands what \t is - if your group thinks that's too obscure, then don't use it.

 

I often use \n in strings for newline if they're embedded. I'll use Environment.NewLine for piecing strings together. For example:

string s = "You are about to delete your whole Database and format the hard drive.\n\nAre you sure?"
string s2 = "Bob" + Environment.NewLine;
s2 += "The" + Environment.NewLine;
s2 += "Builder";

 

Of course, I'd probably use StringBuilder in place of s2, but I don't want to type that out right now...

We're using VB.NET, so \t and \n aren't an option, but thanks anyway.

[JDYoder]

In working with something different, I came across the "ControlChars" object in the helpfile. If you type it and hit "." you'll find methods such as...

 

ControlChars.NewLine

ControlChars.CrLf

ControlChars.Tab

 

Along with a few others. (The first two above are the same thing.) Not sure if they are more or less preferred over System.Environment.NewLine, but thought I'd pass it on if others are interested at least in the .Tab, which I think is handy.

[JDYoder]

Ah, crud. Just figured out that ControlChars is a part of MS.VB. Never mind. :p

[mandelbrot]

Just out of interest, here, are we talking VS.NET or ASP.NET?

 

I've just tried vbCrLf and it does convert...

 

Is this a good practice/bad practice thing? There seem to be so many of them...
