hey guys,

i am trying to make a tutorial series on how to get started on making a programming language and one of the first tutorials are to do this:

VB

for each a as string in textbox1.text.split(controlchars.lf)
     if a.startswith("print ")
          textbox2.text &= a.substring(6
     end if
next

if you go and run this code, it will run just fine. but you will not be able to make new lines. i want to be able to make a new line with the command 'newline' but i don't know how to. can you guys please give me an answer that is in the 'for each' statement? this is a sample code that you can try:

print Hello World
newline
print Something

result:

Hello World
Something

Don't you think it would be a good idea for you to understand what is going on and how to do things before you start writing tutorials?

I'm pretty sure that any tutorial written by a beginner is going to miss out a lot of important stuff. For example, the lack of use of the StringBuilder class in your example, the use of Visual studio default names...

Try this:

VB

textBox2.Text = "Hello" + Environment.NewLine & "Goodbye"

Solution 1

Hi,
Please check for this-
Have you set your textbox property to multiline?
try using VbCrlf it is used for newline in VB.NET

Using foreach is simple enough:

VB

for each a as string in textbox1.lines()
.
.
next

that isn't what I wanted. I want the code to be able to make new lines in TextBox2. If you run my code in the question, it doesn't allow new lines in TextBox2. I want to be able to have new lines in TextBox2. Can you please give me a code for this?
