Hi guys,

I've currently in progress of creating this guessing number app on android eclipse, I'm not too sure why it constantly crashes when I press the guess button. Below is the source code that I created:

Please can you provide suggestions or advice for code alterations?

I'm currently using this app for practice on coding

Many thanks,

Hi guys,

I'm currently creating an android app of a number guessing game, what I'm trying to do is, I want the user to be able to look back at how many tries they have tried to guess the number until they reached to the correct number. Below is what I've got but it is giving me an error that I can't seem to solve:

http://pastebin.com/EnUbsTRv

Error:

Count cannot be resolved or is not a field

The type of the expression must be an array type but it resolved to List<Integer>

I've been trying to solve this all day and can't figure out why, this app is for practice for when I get back into uni in October.

Please can you provide me advice and suggestions to alter the code in some way?

Many thanks,

Hi guys,

Does anyone know how to fix the android programming?

Whenever I try to load up a triangle shape by following the tutorial, it either comes up with hello world or it comes up with an error saying "Unfortunately [file name] has stopped"

I have tried changing the target version on the android sdk but I still can't figure out where I have gone wrong

Please can anyone help me out?

Thanks

Hi guys,

Is that a normal temperature for computer?

I have just purchased a customised desktop computer from a company and when I started it up, installed the stuff that i needed such as motherboard and graphics card etc. Then when I come to test the computer out, inside the case is like 55 degrees hot.

I don't have experience with hardware

Does anyone know how to do a date format validation for c#? Heres my code below:

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 Calculate_reservation_totals

{

public partial class CalReservationTotals : Form

{

public CalReservationTotals()

{

InitializeComponent();

}

private void CalReservationTotals_Load(object sender, EventArgs e)

{

const int pricePerNight = 115;

txtPrice.Text = pricePerNight.ToString("£.00");

}

private void butCalculate_Click(object sender, EventArgs e)

{

DateTime arrival;

DateTime depart;

if (String.IsNullOrEmpty(txtArrival.Text) || !DateTime.TryParse(txtArrival.Text, out arrival))

{

MessageBox.Show("Please enter a date");

return;

}

arrival = arrival.Date;

if (String.IsNullOrEmpty(txtDepart.Text) || !DateTime.TryParse(txtDepart.Text, out depart))

{

MessageBox.Show("Please enter a date");

return;

}

if (depart > DateTime.Today)

{

MessageBox.Show("The arrival date cannot be before the departure date");

return;

}

if (arrival < depart)

{

MessageBox.Show("The departure date cannot be before the departure date");

return;

}

if (arrival == depart)

{

MessageBox.Show("The arrival date and the departure date cannot be on the same date");

return;

}

double nights = (arrival.Subtract(depart).TotalDays);

double price = nights * 115;

string numberOfNights = nights.ToString();

txtNights.Text = numberOfNights.ToString();

string totalPrice = price.ToString("£.00");

txtTotal.Text = totalPrice.ToString();

}

private void butExit_Click(object sender, EventArgs e)

{

this.Close();

}

}

}

Please give me any suggestions for alteration.

Thanks

This is what I have done already:

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 Calculate_reservation_totals

{

public partial class CalReservationTotals : Form

{

public CalReservationTotals()

{

InitializeComponent();

}

private void CalReservationTotals_Load(object sender, EventArgs e)

{

const int pricePerNight = 115;

txtPrice.Text = pricePerNight.ToString("£.00");

}

private void butCalculate_Click(object sender, EventArgs e)

{

double nights = 0;

DateTime arrival;

DateTime depart;

if (String.IsNullOrEmpty(txtArrival.Text) || !DateTime.TryParse(txtArrival.Text, out arrival))

{

MessageBox.Show("Please input a date");

return;

}

arrival = arrival.Date;

if (String.IsNullOrEmpty(txtDepart.Text) || !DateTime.TryParse(txtDepart.Text, out depart))

{

MessageBox.Show("Please input a date");

return;

}

depart = depart.Date;

if (depart > DateTime.Today)

{

MessageBox.Show("The arrival date cannot be before the departure date");

return;

}

if (arrival < depart)

{

MessageBox.Show("The departure date cannot be before the departure date");

return;

}

if (arrival == depart)

{

MessageBox.Show("The arrival date and the departure date cannot be on the same date");

return;

}

double duration = (arrival.Subtract(depart).TotalDays);

txtNights.Text = duration.ToString();

double price = nights * 115.00;

txtTotal.Text = price.ToString();

}

private void butExit_Click(object sender, EventArgs e)

{

this.Close();

}

}

}

I'm expecting it to do the final calculations for the total cost, but it doesn't do it for me. I have already inputted the coding in but can't figure it out whats wrong.

Please can anyone give me suggestions for alterations?

thanks

The program won't run when I debug it, I don't know whats wrong with it, this is the code that I wrote:

}

}

double miles = 0;

}

else if (Conversions.Text == "feet to metres")

{

{

}

metres = feet * 0.3048;

txtBox.Text = metres.ToString();

}

else if (Conversions.Text == "metres to feet")

{
