Well, Here is my current codes in the Windows Application program
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.IO;
// add private fields
private string[] lines;
private int currentLine = -1; // dummy value
private void frmCustomerDetails_Load(object sender, EventArgs e)
{
//Reads records from a file
lines = File.ReadAllLines(@"C:\mp2.txt");
// display first one
DisplayRecord(0);
}
private void DisplayRecord(int index)
{
// don't do anything if index is outside bounds of lines array
// or if requested line is already displayed
if (index < 0 || index >= lines.Length || index == currentLine)
return;
string[] records = lines[index].Split('#');
txtCustomerID.Text = records[0];
txtContactPerson.Text = records[1];
txtAddress.Text = records[2];
txtContactPerson.Text = records[3];
txtContactNo.Text = records[4];
currentLine = index; // update currentline
}
private void btnFirst_Click( object sender, EventArgs e)
{
DisplayRecord(0);
}
private void btnNext_Click( object sender, EventArgs e)
{
DisplayRecord(currentLine + 1);
}
private void btnPrev_Click( object sender, EventArgs e)
{
DisplayRecord(currentLine - 1);
}
private void btnLast_Click( object sender, EventArgs e)
{
DisplayRecord(lines.Length - 1);
}
Is there a way I could add records from the existing notepad (mp2.txt), wherein, you could still display all the previous items
plus the one you've added? Another, is there a possibilty that I could still edit my previous record from the 'mp2.txt' and save it
afterwards?
here's the thing
btn_Add - Adds a new record...then put on the last record of mp2
btn_Edit - edits the the one who is currently displayed by the textboxes...
btn_Save - saves the changes when Edit process was finished already....
btn_Cancel - if you wish to cancel the edit process..
(by the way, once added a new record, there should have an input recorded to the mp2.txt as well at the last part)
Sorry if I ask too much. I'm kinda confused with all these stuff. Noob me.
