How to read the line one by one and read out the data correspond?

[youqing]

Hello, all:
I have a problem like this:
I created a database in txt.like this:
"143483",1234
"143484",1235
"143485",5588
"143486",5876
"143488",8568
"143487",8756
.......
I want to make a program which can search the data and read out the data using VB.
If I input the 143483 into the program, the result will be 1234.
I programmed like this:
Private Sub Command1_Click()
Dim Target As String
Dim Current As String
Open "E:\test1.txt" For Input As #1
Do While Not EOF(1)
Line Input #1, Current
If (Current = Target) Then
Label3.Enabled = True
Text2.Enabled = True
Text2.Text = Barcode.Width
Exit Do
ElseIf (Current <> Target) Then
Do Until EOF(1)
Loop
End Sub
But it is not working. Hope someone can help me to slove this problem. thanksssss a lot!

first things first:
you have opened file as 1, you NEED TO CLOSE IT. bad form to leave it hanging.
second thing:
you have an if statment, you have no end if...?
third thing:
you have 2 do's, and only 1 loop...?

Private Sub Command1_Click()
Dim Target As String
Dim Current As String
Dim Result As Long
'input target ("143483")
Open "E:\test1.txt" For Input As #1
Do
Input #1, Current
If (Current = Target) Then
Label3.Enabled = True
Text2.Enabled = True
Text2.Text = Barcode.Width
Input #1, Result
Exit Do
End If
Input #1, Result
Loop Until EOF(1)
Close 1
'output result (1234)
End Sub
