[RESOLVED] string problem

[jain_mj]

In my project, I have a multiline textbox (txtInput) in
the main form and the user inputs a list of strings. Then I have to copy the input data into an array of strings (StrArray) So I did this:

StrArray = txtInput.Text.Split(vbCr)
For i = 0 To StrArray.GetUpperBound(0)
    StrArray(i).Trim(vbCr) 
    'I trid StrArray(i).Replace(vbcr,"") also.
    'I tried to trim/replace vbcr,vbnewline and vblf
 
' to see the results
TextBox2.text &= strarray(i)
Next

But in the textbox2, I saw one special char in each string
except in the first string. I copied that special char and
pasted in notepad. That char is something like an 'enter key'
How can I remove it?

I tried this also

StrArray = txtInput.Text.Split(vbCr)
For i = 0 To StrArray.GetUpperBound(0)
    ListBox1.Items.Add(StrArray(i).Replace(vbLf, ""))
Next
ListBox1.Items.CopyTo(StrArray, 0)

Now it works fine. I want to know whether there is any method
to do this without using listbox.

Check the correction below, You were not assigning the modified(replace) value to anything.

Dim StrArray() As String, i%
        StrArray = TextBox1.Text.Split(vbCr.ToCharArray)
        For i = 0 To StrArray.GetUpperBound(0)
 
            StrArray(i) = StrArray(i).Replace(vbLf, " ")
 
            ' to see the results
            TextBox2.Text &= StrArray(i)
        Next

If you wanted to use the Split function you would use a different one:

StrArray = System.Text.RegularExpressions.Regex.Split(TextBox1.Text, Environment.NewLine)

Regex.Split allows you to split on a string instead of just a single character. The good news is that you don't have to use any method because you already have an array of individual lines in the RichTextBox.Lines property.

I thaught that StrArray(i).Replace(vbLf, " ") will change the original string. thanks for that.
Thanks jmcilhinney, I am going to use richtextbox.
