Question

yesterday i asked one question and got the answer from our friend here, and i ran successfully, also it have one problem with it. “Yester day My question is, when we selecting the drop down list then it should be shown by a label as “1” at very first time, again it’ll be increas by selection”, this is what the answer i got..,

static int count = 0;
private void bind()
{ 
    ArrayList ar = new ArrayList();
    ar.Add("first"); 
    ar.Add("Second");
    ar.Add("Third");
    ar.Add("Four");
    ar.Add("Five");
    ar.Add("Six"); 
    ar.Add("Seven");
    CCddl.DataSource = ar;
    CCddl.DataBind();
}

protected void CCddl_SelectedIndexChanged(object sender, EventArgs e)
{
    if (count == 0) count = 1;
        Label12.Text = count++.ToString(); 
}

this code worked, but once the running window getting closed, then it lose the continuation, i mean again application getting run it’ll shown again “1”. But exactly what i want is, the number continuation should be end when the system day has change.

Try using the Application Settings feature. I added two user settings CountDate and Count in the Project->Property’s->Settings and changed your SelectedIndexChangedEvent to

protected void CCddl_SelectedIndexChanged(object sender, EventArgs e)
{
    if (count == 0) count = 1;
        Label12.Text = count++.ToString();

    Properties.Settings.Default.CountDate = DateTime.Now.Date;
    Properties.Settings.Default.Count = count;
    Properties.Settings.Default.Save();
} 

And right before you call your Bind Method during your form initialization put something like this.

 if(Properties.Settings.Default.CountDate.Date != DateTime.Now.Date)
 {
    Properties.Settings.Default.Count = 0;
    Properties.Settings.Default.CountDate = DateTime.Now.Date;
    Properties.Settings.Default.Save();
 }
 else
    count = Properties.Settings.Default.Count;

 bind();
