Hello,

I am New @ Vb.Net and I have a problem in writing data in a notepad.
The problem is that,It should write the heading in the file only once,but instead it repeats it for each and every data I write.
eg it should write like this
Name Surname
Lucky Thami
Bebeza Slago
instead it writes
Name Surname
Lucky Thami
Name Surname
Bebeza Slago

Hope and trusting you can Understand the problem
Thx:)

I am a bit confused.
Have you already written the program?
If so, could you post the source code, some sample input and the desired output?

 'Declare variable swrWrietr as streamwriter
        Dim swrWriter As IO.StreamWriter

        'Create a file
        swrWriter = IO.File.AppendText("Sample.txt")
        'Write Heading first only onec NB Don`t Repeate the heading
        swrWriter.WriteLine("Name " & Space(10) & "Surname")
        'write on the Name and Surname @ runtime
        swrWriter.WriteLine(txtName.Text & Space(10) & txtSurname.Text)
        swrWriter.Close()

Hello LT Bebeza:
I think you have change the code as follows

  'Declare variable swrWrietr as streamwriter
        Dim swrWriter As IO.StreamWriter

        'Create a file
        swrWriter = IO.File.AppendText("Sample.txt")
        'Write Heading first only onec NB Don`t Repeate the heading
        swrWriter.WriteLine("Name " & Space(10) & "Surname")
 forecah(.....)
{
        'write on the Name and Surname @ runtime
        swrWriter.WriteLine(txtName.Text & Space(10) & txtSurname.Text)
}
        swrWriter.Close()


I hope it will solve your problem.

If you still you have problem then please provide the details where( in which method) you were writing above lines of code and how you are using ( calling written method).

Regards
Kristi.

the problem is that at Run time it Repeats The statement
swrWriter.writeline("Name " & Space(10) & "Surname")

Which it must not Repeat

LT Bebeza

One weak solution cud be the usage of flag - a bool variable.
Donno the syntax of VB, but the logic is as follows:

static bool flag = false; //initialized somewhere
//in-between code
if(!flag)
{
    swrWriter.WriteLine("Name " & Space(10) & "Surname")
    flag = true;
}
//rest of the code

Hope it works.
