Hi all,
I need to add a new line of items into RiceName.txt as below:-
If File.Exists(File.DirDefaultExternal,"RiceName1.txt") Then
Dim Writer As TextWriter
Writer.Initialize(File.OpenOutput(File.DirDefaultExternal,"RiceName1.txt",True))
Writer.WriteLine(TxtRRName.Text & "," & TxtUUPrice.Text )
Writer.Close
End If

I have problem Why not add another line?

Before-Add :- information is
aaa,20
bbb,30
ccc,40

After-Add :- information is
aaa,20
bbb,30
ccc,40ddd,50 <= Error information

Please correct them.

Best Regards
Theera

The thread title should summarize the question.

WriteLine adds a new line character at the end. If you need to add at the beginning then you should write:

Writer.WriteLine(CRLF & TxtRRName.Text & "," & TxtUUPrice.Text)

You should run your code in Debug mode and see the exact error line.

I didn't see something really wrong in this coding. I think Erel is right, since the error probably is somewhere else in your string-processing routine. See the attached file.

Hi MC73,
Thank you for example. I don't understand that After I input data and press button ,the information is display,but I re-run the wiget again,the information which I need to display should be below:-

Before-Re-run:
aaa,20
bbb,30
After-Re-run
ccc,40 <= prior data is lost

it should be below:

aaa,20
bbb,30
ccc,40

Best regards

Using the example I've sent, nothing like this is happening. Check if you have somewhere, code for recreating your txt file. Or you can upload a zip file containing your code, so that members of this forum can help you.
