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

By Mike Prestwood

Delphi versus VB.Net: A side by side comparison between Delphi and VB.Net.


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] 
Delphi:   LeftStr
Syntax Example:
Uses StrUtils;
ShowMessage(LeftStr('Prestwood', 3));
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))
