On Windows, put:
Module HalloWelt Sub Main() Console.WriteLine("Hallo, Welt!") End Sub End Module
in a textfile with any texteditor, save it as fnord.vb
then on a cmd.exe ,type:
C:\%SystemRoot%\Microsoft.NET\Framework\v2.0.50727\vbc.exe fnord.vb
(or wherever you have vbc.exe, which is the visual basic compiler) (*)
(*) If you cant find vbc.exe on your box you need to install .Net Framework, you dont need the complete SDK, that is optional.
.. and you will have a new fnord.exe and compiled your own windows commandline executable.
C:\fnord.exe Hallo, Welt!
ergo: also on Windows you dont need a GUI to create applications.
Beispiel Nettoberechnung[edit]
' Berechnet Nettobetrag aus Bruttobetrag und Steuersatz Imports System.Console Module T1 Sub Main() Dim br as Double Dim st as Double Dim netto as Double Dim nochmal as String WriteLine("'Programm T1' - Berechnet Nettobetrag aus Bruttobetrag und Steuersatz") DO br=0 DO WHILE br <= 0 WriteLine("Bitte einen Bruttobetrag eingeben. (Der Bruttobetrag muss > 0 sein.): ") br=ReadLine(): LOOP st=0 DO WHILE st <= 0 OR st > 100 WriteLine("Bitte einen Steuersatz in Prozent eingeben (Steuer muss > 0 und <= 100 sein!) %: ") st=ReadLine(): LOOP netto=br-(br/100*st) Write("Der Nettobetrag ist: ") WriteLine(Netto) Write("Nochmal rechnen? (j/n): ") nochmal=ReadLine(): LOOP UNTIL nochmal="n" End Sub End Module
