So pick out all the bits that add to the width of a column, multiply that by the number of columns in the data, add a bit and set your with to that. Run your app and when it looks horrible try and work out what you have missed. Get the max and min of your data range and that will help define your height.

Calculate the largest value.
Assign 100 to this value.

Then assign a proportional value to the other values based on the proportion of a percentage to the highest value.

Plot your values based on this percentage.

Hi, I want to create a windows phone 7.1 app for finding the closest postcode too 4 predefined postcodes, I have found an access db that has all the uk postcodes in so i thought I would start by with a simple postcode query and work from there but I am struggling to fidd a query tutorial that will go through query a database.

could someone point me in the right direction please,

regards

It will depend on the geo coding of your source data. When I did something like this in about 2002 I found the postcodes in Britain change from 1 month to the next so there was a need to subscribe to one of the geo coding sources, was very expensive at the time.

Mycroft,

thanks for the reply, I am able to get the UK list for free from the post office at present so I would like to go down the database route for this exercise as I have not worked with databases before on windows mobile, I am struggling to find a simple user input query project to help me get started.

What version of Visual Studio are you using? Ultimate or Premium 2012/2013 can use a Fakes assembly which addresses specifically this with "Shims".

Or are you using some other kind of testing software (please specify)?

An idea would be to write a simulation program which is sending dummy data to a virtual serial port at which your program is listening. You could pair those two virtual ports using com0com.

{Uin32} {Uin32, Uin32, String, Uin32, double}

How can i access each element in C#
I used this command
IronPython.Runtime.List pRFList = rf_model.model(ut_rx_list, ut_tx_list);
how can i walktrough this list (like foreach command)

thanks in advance

According to this[^], IronPython.Runtime.List implements IList<object> and IList, so a foreach loop should work.

Errm, ..., no.

But have a look at MSDN on the Process class[^]. It is used to start other processes.

Pay special attention to its StandardOutput[^] and StandardError[^] properties. They give you access to the called processes' outputs.

Finally, use File.WriteAllText()[^] to store the results in a file.

Or forget it all and go for Eddy Vluggen's proposal.

No.

That isn't how it works here.
We don't do homework, and we don't do your work for you either.
If you want code written for you to a specific specification, you have to pay - I suggest you go to VWorker.com and ask there.

But be aware: you get what you pay for. Pay peanuts, get monkeys.

If on the other hand you try to do it and get stuck, then feel free to ask for help with a specific problem and we will be glad to assist.
But we aren't going to do it all for you.

Change Content of Button

Member 1037988611-Nov-13 10:27

Member 10379886

11-Nov-13 10:27

Hi I am doing an exercise to change the content of a button 9windows app 7.1 VS2012)

I create the project and then its says

SQL

Drag a Button on to the Designer.  See how it updates the Xaml with the Button tag.  Selecting items in the Document Outline Window allows you to navigate the Xaml tree and it selects the item visually as well as in the Xaml.  It is a handy way to navigate complex Xaml if not all of the Xaml is visable.
 Select the Button go to the properties Window - this also creates events.
You can edit the control in the Properties Window or hand-edit the Xaml. To create an event you can either use the properties window or edit the Xaml.
To do this go to the Xaml for MainPage.xaml and find the Button that was added.  Type Click= and then tab to create the event handler.  This has been added in the code-behind .cs file.  Type Button1.Content = "Hello World!"

I have done what it has say and my MainPage.xaml.cs looks like this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls;

namespace Hello_World
{
    public partial class MainPage : PhoneApplicationPage
    {
        // Constructor
        public MainPage()
        {
            InitializeComponent();
        }

        private void Button_Click_1(object sender, RoutedEventArgs e)
        {
            Button.Content = "Hello World";
        }
    }
}


the 'Button.Content' produces this error:

Error	1	An object reference is required for the non-static field, method, or property 

My MainPaipe.zaml has the following code in but no errors

<phone:phoneapplicationpage 
="" x:class="Hello_World.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone" xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:ignorable="d" d:designwidth="480" d:designheight="768" fontfamily="{StaticResource PhoneFontFamilyNormal}" fontsize="{StaticResource PhoneFontSizeNormal}" foreground="{StaticResource PhoneForegroundBrush}" supportedorientations="Portrait" orientation="Portrait" shell:systemtray.isvisible="True">

            <rowdefinition height="Auto">
            <rowdefinition height="*">
        

        
        <stackpanel x:name="TitlePanel" grid.row="0" margin="12,17,0,28">
            <textblock x:name="ApplicationTitle" text="MY APPLICATION" style="{StaticResource PhoneTextNormalStyle}">
            <textblock x:name="PageTitle" text="page name" margin="9,-7,0,0" style="{StaticResource PhoneTextTitle1Style}">

            <Button Content="Button" HorizontalAlignment="Left" Height="79" Margin="142,53,0,0" VerticalAlignment="Top" Width="171" Click="Button_Click_1"/>

The problem comes because you are trying to use a variable called Button when there is no such variable. Just because you have defined a Button on the main page, it doesn't mean that the code behind knows about it. There are 2 ways to fix this (without going into doing this via MVVM). The first technique for doing this is to name your button in the XAML using

x:Name="MyButton"

(this goes inside your Button declaration) and then use this name in your codebehind. The second way to do this is to take advantage of the fact that the sender argument refers to the control that set it, so you can do

((Button)sender)....

to set the value.

Im working on a project for school, im suppose to make a console application which will show a Cinema system with 20 seats on 15 rows. I am very green on c# - so any help, Critism, or general thoughts are much appreciated!

I got a 2d array set up now, functionally and with space in between items so its not a mess to look at..
Im trying to take the program to the next level now, my program must show which seats are available, and which are taken,
and the program must let you book certain seats, and random seats.
I was thinking to make all the available seats green, and once you booked your seats they should go red -

How can i start doing this proberly?
I think im looking for background Color, and maybe If / else statements?

Here is how my program looks so far:

Console.WriteLine("|--------------------------CINEMA--------------------------|\n");
            int[,] pladser = new int[,]
                {
              {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20},
              {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20},
              {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20},
              {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20},
              {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20},
              {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20},

              {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20},

           };

                    for (int y = 0; y < pladser.GetLength(1); y++)
                    {
                        Console.Write("{0,3}",pladser[x, y]);
