Left of String (VB.Net and ASP Classic Cross Reference Guide)

By Mike Prestwood

VB.Net versus ASP Classic: A side by side comparison between VB.Net and ASP Classic.

Commands

Common commands (procedures and functions). A function returns a value. Optionally, it may also perform an action prior to returning a value. A procedure does not return a value or it returns void or null.

Left of String

[Other Languages]

VB.Net: "Left of Substring" Left or Substring

The above usage of Left and Substring are equivalent.

Left is a traditional VB approach popular with developers moving from VB Classic to VB.Net. Substring is considered the .Net way of doing string manipulation.

Syntax Example:

Dim FullName

FullName = "Prestwood"
Console.WriteLine("Hello " + Left(FullName, 4))
Console.WriteLine("Hello " + FullName.Substring(0, 4))

ASP Classic: Left

Syntax Example:

Dim LeftString

LeftString = Left("Prestwood", 3)

Response.Write LeftString
