Hi,
My OS is Windows XP. I am using Firefox and IE.
I installed Silverlight 4, 3, and 2. All these version does not work for me.
How can I fix this?
Thanks

I have no idea from this what problem you are facing. Can you not view any Silverlight content?
|
|
|
|
|

It's hard to tell the kind of problem you're facing. have you tried this on another PC running the same features as your PC? There are certain test you need to do in order to know is the problem is a generalized one or it's only specific to your PC.

for the first time silverlight ask for download if you have some firewall or if you rejected that file then also it may show you blank page...
if possible post your code which is used to call ...

Hello,
My goal is to add dynamically some control to the main window.
When the user preeses mouse right button on the window the position where the button pressed is the top left of the control, then the user keeps the button pressed and drags the mouse on the window and the position where he releses the button is the right bottom of the control.
What i want is while the user drags the mouse while he is pressed is that some square appear on the screen to show user the size of the control that will be created.
This is exactly like when you try to create new fence on youre desktop with the "Fences" application.

And your problem is?

My problem is how to paint the square on the window while thw user moves the mouse with right button pressed:
I want the square to be transparent but vissible and his size changing if the user move the mouse
|
|
|
|

Although I don't really get your question fully and I don't know what Application platform (WPF or Silverlight or Winform)you're using but I will suggest this. You need to work with three parameters: The height of your square, the width and the mouse pointer position. You will need to do some math to calculate a new width and height for your square based on the position of the mouse pointer.
I will suggest that you make your question more clearer so that people can really understand you and help you out.

Hi,
What is the difference between windows 7 86x and 64x ?
I would like to purchase a laptop with windows 7 for silverlight, wpf and windows phone 7, sql server 2008 developments.
I know I can install the sql server 2008 express and visual studio 2010 express on windows 7 but not sure whether to have 86x or 64x.
Any thoughts please?
Thanks

x86 is 32 bit and x64 is 64 bit hardware, so you need to get the version that matches your hardware. If you are buying a totally new system then go for 64 bit.
|
|
|
|
|
To confirm, for the purpose of developing using sql server 2008 express, visual studio 2010 express and windows phone 7, then it is ok to have windows 7 home edition 64 bit?
Thanks

This is not a software issue, you can only use 64-bit software on a PC that has 64 bit hardware. If your PC is not a 64-bit machine then you cannot install 64-bit software on it.

The machine is a 64bit hardware... and comes with windows 7 home edition 64bit.
for the purpose of developing using sql server 2008 express, visual studio 2010 express and windows phone 7 is the home edition ok for my purposes?
Thank you

Hello everyone,
I am making a sample application test with WPF creating some UserControls to increase maintainability.
In this way I created a toolbar usercontrol where I put a combobox and I created a dependency property, since it's the best tool for binding than datacontext when having more than one binding, and in main xaml I called a xmldataprovider loading a xml file to fill the combo box in the UserControl.
in the toolbar's usercontrol xaml file I put
<ComboBox ItemsSource="{Binding Path=epToolbarItemSource, RelativeSource={RelativeSource AncestorType={x:Type UserControl}}}" DisplayMemberPath="shortname" />
In the toolbar's usercontrol xaml.cs file I declared the dependency property as:
public static DependencyProperty ItemSourceToolbarProperty;
static epToolbar()
{
epToolbar.ItemSourceToolbarProperty = DependencyProperty.Register("epToolbarItemSource", typeof(IEnumerable),
typeof(epToolbar));
}
public IEnumerable ItemSourceToolbar
{
get { return (IEnumerable)GetValue(epToolbar.ItemSourceToolbarProperty); }
set { SetValue(epToolbar.ItemSourceToolbarProperty, value); }
}
In the Window.xaml file I declared the xmldataprovider as:
<XmlDataProvider x:Key="dpOperators" XPath="operators" Source="/Data/Operators.xml" IsInitialLoadEnabled="True" />
and I declared the usercontrol setting the dependency property I thought it was correctly declared, epToolbarItemSource:
<uc:epToolbar DockPanel.Dock="Top" epToolbarItemSource="{Binding Source=dpOperators, Mode=TwoWay}" />
In the examples found about Dependency Properties I always read the dependency property can be called as a property attribute when calling the usercontrol but in this case it says an error like: "The property 'epToolbarItemSource' was not found in type 'epToolbar'."
So I am asking here what's the right syntax to bind the content of xml file to the combo in the way I add new operators in the xmldataprovider so they would be inserted in xml file and refreshed the combo box?
Thanks in advance to all
Cheers, Luigi

Ok,Sort of new to WPF and MVVM I have a function to populate a treeview control on a User Control. I placed the code to populate the treeview list inside the code portion of the User Control. I need to update this treeview list by calling the function from inside another hosted User Control. How do I do this?
I have added #include Manufactured_Housing_Manager which is the projects namespace I've even tried #using tv = Manufactured_Housing_Manager.Treeview, which was the name of the usercontrol.
How can I call the update from another User Control

**NEVER** build a TreeView by hand. ESPECIALLY in WPF/MVVM. You should build a simple nested collection and then use a HierarchicalDataTemplate to define how to populate the TreeView from that collection. The collection(s) should implement INotifyCollectionChanged and the objects inside of the collection(s) should implement INotifyPropertyChanged. Then just simply set the ItemsSource of the TreeView to point to your collection and sit back and watch the magic happen. If you do this, any changes you make to your collection(s) and item(s) will auto-magically be reflected in the UI.

How do I populate that type of Treeview? I've created a listview such like you said for my MRU list I need to populate the Treeview with sorted data by Alphabetic base letter A-Z then Lastname, Firstname middle intial. I'm already using a collection:
using System;
using System.Collections.ObjectModel;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ComponentModel;
namespace Manufactured_Housing_Manager
{
public class tvIndex
{
private string _index;
public string Index
{
get { return _index; }
set { _index = value; }
}
private ObservableCollection<Contact> _contacts;
public ObservableCollection<Contact> Contacts
{
get
{
if (_contacts == null)
_contacts = new ObservableCollection<Contact>();
return _contacts;
}
}
public tvIndex()
{
}
public tvIndex(
string indexx,
ObservableCollection<Contact> contacts)
{
_index = indexx;
_contacts = contacts;
}
}
}
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace Manufactured_Housing_Manager
{
public class Contact
{
private string _name;
private int _id;
public string Name
{
get { return _name; }
set { _name = value; }
}
public int Id
{
get { return _id; }
set { _id = value; }
}
public Contact()
{
}
public Contact(string name, int id)
{
_name = name;
_id = id;
}
}

You mean, you want your tree to look like:
A
ALastName, AFirstName
ALastName2, AFirstName2
B
BLastName, BFirstName
BLastName2, BFirstName
?
