Hi
I've have a Windows form application, that provieds users to add/see and search new items, items are saved into a text file with a help of streamreader/streamwriter.
My application is almost finished, but i dont know how to make a search system.
This is my application:
Code:
This is the code for the display the data that is saved into .txt file
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO;
using System.Collections;
namespace Lekarna
{
public partial class Izpis_zravil : Form
{
int vrstice;
public Izpis_zravil()
{
InitializeComponent();
Vel();
string[] polje = new string[100];
ListViewItem item1 = new ListViewItem();
string filename = "zdravila.txt";
if (File.Exists(filename))
{
string[] lines = File.ReadAllLines(filename);
for (int j = 0; j < vrstice; j++)
{
polje[j] = lines[j];
if (j % 5 == 0)
{
item1 = new ListViewItem(polje[j]);
listView1.Items.AddRange(new ListViewItem[] { item1 });
}
else
item1.SubItems.Add(polje[j]);
}
}
}
public string Vel()
{
StreamReader beri = File.OpenText("zdravila.txt");
string input = null;
while ((input = beri.ReadLine()) != null)
{
vrstice++;
}
beri.Close();
this.Invalidate();
return "";
}
private void button2_Click(object sender, EventArgs e)
{
this.Close();
}
private void listView1_SelectedIndexChanged(object sender, EventArgs e)
{
}
private void pictureBox1_Click(object sender, EventArgs e)
{
}
private void button2_Click_1(object sender, EventArgs e)
{
this.Close();
}
}
}This is the code for saving the items
private void button1_Click_1(object sender, EventArgs e)
{
FileInfo fi = new FileInfo("zdravila.txt");
using (StreamWriter sw = fi.AppendText())
{
sw.WriteLine(textBox1.Text);
sw.WriteLine(textBox2.Text);
sw.WriteLine(textBox5.Text);
sw.WriteLine(textBox3.Text);
sw.WriteLine(textBox4.Text);
}
MessageBox.Show("Zdravilo shranjeno!");
}Sorry for my bad english.Thanks for helping :)
