OPEN Files

Hello,
How do you open a text file for editing?
Example.

I open a text file that has 3 lines.

textfile1
Hello this is vb world.
How are you today.
Wow im bored.
- end of file

Now how would i go about inserting an extra line w. out erasing the rest.

Thanks.

To open:

Dim strLine$
Open "FILE" For Input As #1
Do While Not EOF(1)
Line Input #1, strLine$
Text1.text = Text1.text & strLine$
Loop
Close #1

To save:

Open "FILE" For Output As #1
Print #1, Text1.text
Close #1

Im just trying to edit.

If i open a file and use it as output and then
use the print command filenumber and text, it will erase
all other previous text in the file.
I am just wanting to add to it.

use the open "FILE" for append as #1
example:

Code:

---

Dim strLine$
Open "FILE" For Append As #1
Do While Not EOF(1)
    Line Input #1, strLine$
    Text1.text = Text1.text & strLine$
Loop
Close #1

I think that will work. If now, just go to Kedaman's webpage, he has a good tutorial all about file opening and editing. http://www.geocities.com/kedasu/kedamans_file.htm
Check out the rest of his site too, it's got neat stuff on it.

You need to open for Append to add to the file.
Output will overwrite the entire file.

Matthew knows this, it's a slip of the typo.

Code:

Option Explicit

Private Sub Form_Load()
    'use a multiline text box with scrollbars
    Dim i As Integer
    Dim myVar As String
    Text1 = ""
   
    Open "C:\my documents\myfile.txt" For Input As #1
    Do While Not EOF(1)
        Line Input #1, myVar
        If i = 0 Then
          Text1 = myVar & vbNewLine
        Else
          Text1 = Text1 & myVar & vbNewLine
        End If
          i = i + 1
       
    Loop
      Close
     
End Sub
Private Sub Command1_Click()
    'once you have made your changes in the text box
    'ie added a fourth line
    Open "C:\my documents\myfile.txt" For Append As #1
    Print #1, Text2.Text
    Close #1
    'refresh
    Call Form_Load
    Text2 = ""
    Text2.SetFocus
   
End Sub

Okay i got it finally :)

Thanks guys...

You are absolutely right Wayne.
I had Append at first. Than I changed it, than I said to myself, that's not right, than my brother came in and needed help studying for a test and I posted the reply and got distracted and all. Anyways, always go with what you gut feeling tells you. (from Who Wants to be a Millionaire?)

We all make mistake, no ones perfect.

Look at what Wayne does sometimes...

'and then he puts:

again and forgets to close your opened code tag ([/code]).

That annoys me the hell out of me, hehe, but I learn to deal with it :D.

You mean this. :D :D :D :D
