I don't know why I am having so much trouble trying to do this but anyway I need a function that reads 1 line of text from a textbox that is multi-line enabled.

Example of what I need:
Textbox named "txtboxInfo" will have
"21 name <vbCrLF>
22 name1 <vbCrLF>
23 namebn <vbCrLF>"

I need my function which will be called in a loop to get each line and return the line as a string
So if would write  
Dim strInfo As string
Do while (txtboxInfo <> "" )
   strInfo = Getline(txtboxInfo.text)
loop

So that loop should run 3 times and return the following results
Run |  Result
1     |  21  name
2     |  22  name1
3     |  23  namebn

Anyway I don't know why I can't writes this Maybe cause I have been programming for like the last month straight and jumping between java, VB, and C++ So thanks for the help

Later,
Aaron

Hi vbhelp12345,

Use:

Dim aryLines() As String
Dim intLine As Integer
Dim strLine As String
aryLines = Split(txtboxinfo.Text,vbCrLf)
For intLine = LBound(aryLines) To UBound(aryLines)
  strLine = CStr(intLine + 1) & " | " & aryLines(intLine)
  Msgbox strLine
Next

This simply splits the contents of the texbox to an array and then scans the array to display each line

Oh here is my final test program with it implemented

Dim aryLines() As String
Private Sub Command1_Click()

Dim x As Integer
Dim y As Integer
y = Getline(Text1.Text)
For x = 0 To y - 1
MsgBox aryLines(x)
Next
End Sub

Private Sub Command2_Click()
End
End Sub

Private Sub Form_Load()
Dim i As Integer
i = 1
Text1.Text = str(i) + " " + str(i * 23) + vbCrLf
For i = 2 To 29
    Text1.Text = Text1.Text + str(i) + " " + str(i * 23) + vbCrLf
Next
End Sub

Function Getline(strq As String) As Integer
Dim intLine As Integer
Dim strLine As String
aryLines = Split(strq, vbCrLf)
For intLine = LBound(aryLines) To (UBound(aryLines) - 1)
  strLine = aryLines(intLine)
Next

Getline = intLine
End Function
