I ran into an issue where i tried displaying a display box after a countdown reached a certain time but for some odd reason it replicates with each second despite it having already passed the initial time it was supposed to appear. This is what i tried to do but now the timer has stopped and the time remaining column has stopped runng.
public partial class Form1 : Form
{
private List<CSession> sessionlist = new List<CSession>();
private TimeSpan workingTimeSpan = new TimeSpan();
private TimeSpan fiveMinutes = new TimeSpan(0,1,0);
private TimeSpan oneSecond = new TimeSpan(0,0,1);
public Form1()
{
InitializeComponent();
timer1.Enabled = true;
timer1.Start();
}
private void label1_Click(object sender, EventArgs e)
{
}
private void AddTime_Click(object sender, EventArgs e)
{
workingTimeSpan += fiveMinutes;
DisplayWorkingTimeSpan();
}
private void DisplayWorkingTimeSpan()
{
TimerLabel.Text = workingTimeSpan.ToString();
}
private void DecreaseTime_Click(object sender, EventArgs e)
{
TimeSpan fiveMinutes = new TimeSpan(0,5,0);
workingTimeSpan -= fiveMinutes;
DisplayWorkingTimeSpan();
}
private void Confirm_Click(object sender, EventArgs e)
{
CSession newSession = new CSession();
if(PasswordText.Text == "")
{
MessageBox.Show("Password not entered");
return;
}
newSession.password = PasswordText.Text;
newSession.purchased_time = workingTimeSpan;
newSession.remaining_time = workingTimeSpan;
newSession.status = "Online";
sessionlist.Add(newSession);
PasswordText.Text = "";
TimerLabel.Text = "";
workingTimeSpan = new TimeSpan();
}
private void DisplayAllSessions()
{
listView1.Items.Clear();
foreach(CSession c in sessionlist)
{
string[] row = { c.password, c.purchased_time.ToString(), c.remaining_time.ToString(), c.status };
ListViewItem i = new ListViewItem(row);
listView1.Items.Add(i);
}
}
private void timer1_Tick(object sender, EventArgs e)
{
foreach(CSession c in sessionlist)
{
if (c.remaining_time.TotalMinutes == 5)
{
timer1.Stop();
MessageBox.Show("Time almost up for client.");
}
if (c.remaining_time.TotalSeconds < 1)
{
c.status = "Offline";
}
if(c.status == "Online")
{
c.remaining_time -= oneSecond;
}
}
DisplayAllSessions();
}
private void exitToolStripMenuItem_Click(object sender, EventArgs e)
{
Close();
}
}
Add a flag that gets toggled when you display the message, so you won't display it again:
private bool MessageDisplayed = false;
private void timer1_Tick(object sender, EventArgs e)
{
foreach(CSession c in sessionlist)
{
if (c.remaining_time.TotalMinutes == 5 && !MessageDisplayed) // <-- check the flag
{
MessageDisplayed = true;
MessageBox.Show("Time almost up for client.");
}
if (c.remaining_time.TotalSeconds < 1)
{
c.status = "Offline";
}
if(c.status == "Online")
{
c.remaining_time -= oneSecond;
}
}
DisplayAllSessions();
}
Now you can leave the timer running and your message will only appear once.

When salaried button is checked, change label "Hour Pay: " to "Salary" and hide the labels and text boxes below it. When Hourly button is checked, return everything to its initial form.
My main issue is when i execute code it does not hide labels and text boxes.
private void addButton_Click(object sender, EventArgs e)
{
}
private void icontype_CheckedChanged(object sender, EventArgs e)
{
if (salariedRadioButton.Checked == true)
{
hourLabel.Visible = false;
}
else if (hourlyRadioButton.Checked == true)
{
hourLabel.Visible = true;
}
}
private void hourTextBox_TextChanged(object sender, EventArgs e)
{
try
{
weekTextBox.Text =(float.Parse(hourTextBox.Text)40).ToString();
}
catch
{
}
try
{
yearTextBox.Text = (float.Parse(weekTextBox.Text) 52).ToString();
}
catch
{
}
}
I'm not sure what's your expected result, for the hide part, I think you can try this, thanks.
public Form1()
{
InitializeComponent();
this.salariedRadioButton.CheckedChanged += icontype_CheckedChanged;
this.hourlyRadioButton.CheckedChanged += icontype_CheckedChanged;
}
private void icontype_CheckedChanged(object sender, EventArgs e)
{
if (salariedRadioButton.Checked == true)
{
hourLabel.Visible = false;
weekTextBox.Visible = false;
}
else if(hourlyRadioButton.Checked == true)
{
hourLabel.Visible = true;
weekTextBox.Visible = true;
}
}

}
And this is my form 1 code when hitting the Setting button.
public void btnSetting_Click(object sender, EventArgs e)
{
Setting frm = new Setting();
frm.Owner = this;
frm.ShowDialog();
}
Move Settings1.Default.Save(); to the DefaulSetting method, call GetDefaulSetting in the form load event, and call DefaulSetting in the form close event.
You might also consider renaming the methods ReadSettings and WriteSettings so you don't confuse yourself.
Basically I would like to stop my system from allowing the user to be able to create multiple bookings under the same time slot for a booking if that makes sense. My system basically allows a user to make a booking for a walk, and ideally each walk should only be able to be booked from Monday to Sunday during working hours, but a slot should be 1.5 hours each but at the moment, there is no slots, just the date time pickers for the time and date of the booking and for multiple bookings the user can just pick the same time so i do want to get that fixed.
Hopefully this helps- I have attached my code for my "add booking" form so hopefully thats of some use.

I need to calculate the Lb1SumF plus Lb2SumF equal Lb3SumF.
I ran it, and somehow the label3 does not display the expected result.
Here is a screenshot from result.
Here is my code.
private void Form1_Load(object sender, EventArgs e)
{
TX1.TabIndex=0;
}
private void TX1_TextChanged(object sender, EventArgs e)
{
try
{
int sumF;
sumF = Convert.ToInt32(Lb1PriceF.Text) * Convert.ToInt32(TX1.Text);
Lb1SumF.Text = Convert.ToString(sumF); //Label1 sum
}
catch
{
Lb1SumF.Text = "0";
}
}
private void TX2_TextChanged(object sender, EventArgs e)
{
try
{
int sumF;
sumF = Convert.ToInt32(Lb2PriceF.Text) * Convert.ToInt32(TX2.Text);
Lb2SumF.Text = Convert.ToString(sumF); //Label2 sum
}
catch
{
Lb2SumF.Text = "0";
}
}
private void Lb3_TextChanged(object sender, EventArgs e)
{
int i = Convert.ToInt32(Lb1SumF.Text);
int j = Convert.ToInt32(Lb2SumF.Text);
Lb3.Text = Convert.ToString(i+j); // Label3 sum
}
Lb3_TextChanged might never be invoked as you are not changing the text of the label. I would suggest to change it to a private method and not an event handler. Here is what the code could be like:
private void TX1_TextChanged(object sender, EventArgs e)
{
try
{
int sumF;
sumF = Convert.ToInt32(Lb1PriceF.Text) * Convert.ToInt32(TX1.Text);
Lb1SumF.Text = Convert.ToString(sumF); //Label1 sum
// Call to update sum
UpdateSum();
}
catch
{
Lb1SumF.Text = "0";
}
}
private void TX2_TextChanged(object sender, EventArgs e)
{
try
{
int sumF;
sumF = Convert.ToInt32(Lb2PriceF.Text) * Convert.ToInt32(TX2.Text);
Lb2SumF.Text = Convert.ToString(sumF); //Label2 sum
// Call to update sum
UpdateSum();
}
catch
{
Lb2SumF.Text = "0";
}
}
// private void Lb3_TextChanged(object sender, EventArgs e)
private void UpdateSum()
{
int sum = 0;
if(!string.IsNullOrEmpty(Lb1SumF.Text) && !string.IsNullOrEmpty(Lb2SumF.Text))
{
sum = Convert.ToInt32(Lb1SumF.Text) + Convert.ToInt32(Lb2SumF.Text);
}
Lb3.Text = Convert.ToString(sum);
}
Replace you code with this it will work, you are using * operator where you have to use + operator, I have commented that lines in your code and replaced it for better understanding.
Happy Coding

I have an object list view that has two text columns. When I edit the left column and hit tab to go to the right I receive a "ArgumentOutOfRangeException" with an index of -1. Looks like the index is something internal to the list view because I debugged my application and found no errors. Here is the code :
