Prevent line breaks in a TextArea

I encrypt the contents of “Labels” containing information and separate them with an
The encrypted result is displayed in a TextArea in a condensed form (without line breaks) but when I copy-paste (clipboard: Var c As Clipboard and TextArea2.Text = c.Text) the encrypted content in another TextArea of my application, it seems to execute line breaks? Why and how to prevent these line breaks and keep a condensed form?
Generate :

In my App :

Apply the same properties to the two TextArea.
In fact, duplicate the first TextArea, change the name opf the tatget TextArea in the Paste line and run…

This is not a problem of Copy / Paste (IMHO).

not the same. Is the clipboard the cause? very strange.

Maybe you have some clipboard tool, which translates the linefeeds from CR to CR+LF ?
As a workaround, you could filter the linefeeds before loading it into the textbox.

So how do I separate the information fields if I remove the line breaks? maybe using another separator? which neutral separator is generally used in this case?

Your required format has either chr(13) or chr(10) as a line separator.
Your pasted string has chr(13)+chr(10) after each line.

Just replace chr(13)+chr(10) with chr(13) in the complete string.
If that fails, replace chr(13)+chr(10) with chr(10).

So you do not remove the linebreaks. You convert the double line breaks into single ones.

Thanks I will try.

In the same computer / same running OS ?
Do you changed the TextArea Width ?
Do you changed the TextArea Font Nale ?
Do you pasted styled text with text that have a different Font Name ? Font Size ?
Even drag and drop can behave differently if the two TextArea are different (have different properties…).

NB: TextArea styles can be changed when you Paste (or drop) text with different properties (Font Name, Font Size, etc.) even if you set them in the IDE.

You can take a look at the String.ReplaceLineEndings function.

Or do a .ReplaceLineEndings(EndOfLine....)

It’s not “or”, as we are both saying the same thing :wink:

Not really. Not every OS uses chr(13)+chr(10) as Native LineEnding and ReplaceLineEndings will replace all of them with the one given in the Parameter. Or? :slight_smile:

I was just suggesting the ReplaceLineEndings function, not the chr(13) or chr(10) bits.
You can pass any parameter you want, even ReplaceLineEndings(“A”); it’s up to the programmer to choose the correct one (EndOfLine being a good candidate).

Ah! Now i see MY issue. Forum was acting weird on my Machine. You are right. Thank you @Arnaud_N :slight_smile:

How are you encrypting ? Encodebase64 ?
