should be:
FROM Environmnets AS Environmnets_1) WHERE TMushroomHouse.Name='"+ DropDownList1.Text + "'";

The issue is with the , before TMushroomHouse.Name. Is this meant to be an AND statement by any chance? By the way, you should really avoid concatenating things in like DropDownList1.Text to prevent opening your app up to SQL Injection Attacks.

yup..i try to make it like this (Environmnets.DateT =(SELECT MAX(DateT) AS Expr1 FROM Environmnets AS Environmnets_1)) AND TMushroomHouse.Name='"+ DropDownList1.Text + "'";
It doesn't show the error but when i select from dropdownlist, it will not show the output in my textbox

Please do not post twice, just edit the first.
Where are you stuck?
There are only 10 types of people in the world, those who understand binary and those who don't.

And when you have finished not posting twice, just go and see Mr Google - he has lots, and lots of examples of code that does that. In future, please try to do at least basic research yourself, and not waste your time or ours.

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));
});

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.
