You create them in the same way you create a single event - just more of them. Until you tell us what effect you are after, this is as close to an answer as we can get I'm afraid.

This is not a write an application to order service. If you want this functionality then you need to at least attempt to write it yourself. No one here is going to write the whole thing for you.

Hi ,
I need to change culture mainly between two languages ; italian and English using the Combobox in WPF MVVM.
I tried to databind the ViewModel with my Mainview but I didn't succeed.
I will be so thankful if someone could help.
Here is my Combobox declaration in xaml :
<ComboBox IsEditable="True" Text="Language" HorizontalAlignment="Right" VerticalAlignment="Top" Width="95" Margin="34,21,34,0" ItemsSource="{Binding Languages}" SelectedItem="{Binding SelectedLanguage, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Foreground="#FF434C64" removed="Green" Height="24.96" />
Here is View Model definition :
public void ChangeLanguage()
{
if (SelectedLanguage == "en")
{
Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("en");
}
else
if (SelectedLanguage == "it-IT")
{
Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("it-IT");
}
}
Here the declaration within the construcor of my View Model
public ViewModel()
{
LoadData();
ChangeLanguage();
Login = new DelegateCommand(this.Logging, delegate()
{
return (!String.IsNullOrEmpty(Username) && !String.IsNullOrEmpty(Password) && !String.IsNullOrEmpty(Email));
});
Register = new DelegateCommand(this.Registering, delegate()
{
return (!String.IsNullOrEmpty(Username) && !String.IsNullOrEmpty(Password) && !String.IsNullOrEmpty(Email));
});

You have already posted this question[^] in the WPF forum, and again in QA[^].
DO NOT post the same question in multiple places across the site.

How can I show particular user information in a page from database using c# AND SQL sErvr 2005 in vs 2008
|

A lot of that is going to depend on how you handle membership, and identify users.
But, the most basic way to do this is to use the Session to store the user info - his username perhaps.
Store teh username when he logs in:
Session["UserName"] = myUserName;
Then, you can display the username just by including it in your HTML:
Welcome <%=Session["UserName"]%>
Or, you can set it into a label in your C#:
Label1.Text = string.Format("Welcome {0}!", Session["UserName"]);

That is a typical homework question! Whose job is it to do your homework? How will you actually learn if you never write a line of code? And: your teacher might find out that you cheated...

Hi,
I have the simple code:
// calibrate 4 mA
double delta = 4.0 - multimeterValue; // double multimeterValue
delta = delta / 0.005; // output 5 uA x step
ushort outValue_4mA += (ushort)delta;
But using double (or floating) numbers, how can I get the results:
delta = 4.0 - 4.02 = -0.02 ? I get delta = 0.01999998 !
delta /= 0005 = 4.0 ? I get delta = -3.99999619 !!
outValue_4mA += delta; if outValue = 2000, here I get 1997 instead of 1996 !!!
My old pocket calculator is better: 4.0 - 4.02 = -0.02 and -0.02 / 0.005 = 4.0 and outValue_4mA = 2000 - 4 = 1996.
What can I do to get the correct results?
thanks

Use the decimal type, not double.
|
|
|
|
|
With decimal type the result is always the same.
|
|
|
|
|
Yes, it does work, IF and ONLY IF the original operands are of Decimal type.
From the code you posted, that's not the case. Those values have to be converted to Decimals first.

The ability to write down things like 4.02 is highly misleading. There is no double with the precise value of 0.02 (or 4.02), because doubles are really an integer multiplied by a power of two, and there is no power of two 2n such that x*2n = 0.02 for some integer x.
So when you write 4.02, that's immediately where the trouble starts - you don't get 4.02 because it doesn't exist.
But anyway, you're working with measurements here, and these numbers are clearly correct to many decimals, at least until you cast it to ushort. Casting to ushort is problematic - it will round down, and so the "slightly less than 4" that was still correct (though it looks incorrect) ends up as 3, which is suddenly far from correct.
I'm not really sure what you should do about that. You could trying rounding, but that also those cases where the answer you get differs from the desired answer by 1.

ok Harold, I will solve the problem using rounding.
I understand very well what is the problem and that doesn't exist a double number with the precise value of 0.02, but I wanted to see if there was some other system easier in C# to work around the problem.

Ah ok, sorry, I guess I'm too used to people not knowing that sort of thing
