How can I tick times from a database in timer (counts down remaining)?
I read time values from a database .
I organize the values in a table layout panel and I want the values to start ticking.
I tried this code, which works, but not exactly like I want:
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;
namespace mahsan
{
public partial class marehet : Form
{
DataAccess da = new DataAccess("db1");
DataTable dt = new DataTable();
TableLayoutPanel tlp1 = new TableLayoutPanel();
RowStyle row = new RowStyle();
DateTime remaining7;
System.DateTime m_StopTime1 = default(System.DateTime);
System.DateTime m_StopTime = default(System.DateTime);
DateTime[] myStrings = new DateTime[0];
TimeSpan[] myStrings1 = new TimeSpan[0];
Label label777 = new Label();
Label label77 = new Label();
TimeSpan remaining1=new TimeSpan();
Timer timer3 = new Timer();
public marehet()
{
InitializeComponent();
tlp1.Size = new Size(400,200);
tlp1.RightToLeft = RightToLeft.Yes;
tlp1.AutoScroll = true;
tlp1.CellBorderStyle = TableLayoutPanelCellBorderStyle.Inset;
tlp1.Location = new System.Drawing.Point(400, 0);
tabPage5.Controls.Add(tlp1);
dt = da.Quary("select * from zman");
myStrings = new DateTime[dt.Rows.Count];
myStrings1 = new TimeSpan[dt.Rows.Count];
for (int i = 0; i < dt.Rows.Count; i++)
{
string gt = TableAccess.GetCell(dt, i, 1);
gt = gt.Substring(0, 8);
TimeSpan duration = TimeSpan.Parse(gt);
myStrings1[i] = duration;
}
timer1.Enabled = true;
dt = da.Quary("select * from zman");
for (int k=0; k< dt.Rows.Count;k++)
{
m_StopTime = default(System.DateTime);
m_StopTime = DateTime.Now.Add(myStrings1[k]);
myStrings[k] = m_StopTime;
}
dt = da.Quary("select * from zman");
for (int i = 0; i < dt.Rows.Count; i++)
{
timer3 = new Timer();
timer3.Enabled = true;
timer3.Interval = 1000;
timer3.Start();
timer3.Tick += new System.EventHandler((sender, e) => timer3_Tick(sender, e, i));
}
public void timer3_Tick(object sender, EventArgs e, int li)
{
if (o == 0)
{
remaining1 = new TimeSpan();
} remaining1 = myStrings[li].Subtract(DateTime.Now);
remaining1 = new TimeSpan(remaining1.Hours, remaining1.Minutes, remaining1.Seconds);
if (o == 0)
{
label77 = new Label();
}
label77.Text = remaining1.ToString();
label77.AutoSize = true;
if (remaining1.TotalSeconds < 0)
{
remaining1 = TimeSpan.Zero;
timer3.Enabled = false;
}
if (o == 0)
{
tlp1.Controls.Add(label77, 1, li);
}
o++;
}
