VB.NET Control Characters |   | Just about anything that can be done in .NET, can be done a few different ways. Like everything else, there are usually trade-offs to using one methodology over another. Anyway, when you want to insert some special characters likeCrLf (CarriageReturn|LineFeed) VisualBasic .NET provides you an excellent mechanism for doing so.
I've seen many <=VB6 programmers point out that you can still use the old school constants like vbCrLf and the like. However, those constants are part of the compatibilty library and may well be deprecated in future additions of .NET. Moreoever, some of the older methods Chr(10) + Chr(13) lack clarity and provide no visible benefit.
Anyway, the truly .NET way to create a CarriageReturn|LineFeed is to use Environment.NewLine but many other characters aren't present in the Environment namespace.
Enough talk, here they are:
VB.NET Value Unicode Value Description
ControlChars.Cr x000D Carriage Return
ControlChars.Lf x000A Line Feed
ControlChars.CrLf x000D & x000A Carriage Return|Line Feed
ControlChars.NewLine x000D & x000A " "
ControlChars.Tab x0009 Tab
ControlChars.Quote x0022 Quotation Mark
ControlChars.Back x0008 BackSpace
ControlChars.NullChar x0000 0 |
So, if you want to use any of these features employing the '.NET' method, they are clear and easy to use. Moreover, if you don't like the verbosity, you can declare a Constant setting it to them, and use the constant as a replacement:
Const a as String = "ControlChars.CrLf"
Dim FistName as String = "William" & a
Dim LastName as String = "Ryan" & a
Dim FullName as String = "William Ryan" & a |
This code yields the same results as substituting a with ControlChars.CrLf and/or vbCrLf.
Obviously this abbreviation defeats the purpose of increased clarity, but my point was just to illustrate how it would work. |
