请协助解决我的TextBox问题 [英] Please help with my TextBox issue

问题描述

大家好，

我正在尝试制作有关如何开始制作编程语言的教程系列，而第一个教程之一就是做到这一点:

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:

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

如果您去运行此代码，它将运行正常.但您将无法换行.我希望能够使用换行"命令换行，但我不知道该怎么做.你们能给我一个针对每个"陈述的答案吗?这是您可以尝试的示例代码:

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

结果:

result:

Hello World
Something

推荐答案

不要以为您最好理解一下正在发生的事情以及如何做事 之前 ，您开始写教程吗?

我非常确定，任何由初学者编写的教程都会错过很多重要的东西.例如，您的示例中缺少使用StringBuilder类，使用了Visual Studio默认名称...

试试这个:

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:

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

您好，
请检查此内容-
您是否已将文本框属性设置为多行?
尝试使用VbCrlf将其用于VB.NET中的换行符

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

使用foreach非常简单:

Using foreach is simple enough:

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