Re: simple wpf timer taking up 50% of resources? how do i fix this?

buy a quad-core and see it consumes only 25% now.
or insert a Thread.Sleep(500) in the for loop
or use a timer instead of a thread

I am finding a solution in wpf which is similar to “treelistview” (http://www.codeproject.com/KB/list/treelistview.aspx)

I have an xml, which has lots of outer an inner node with same number and type of attribute.
According to hierarchy it should create tree and according to attributes it should create columns and display data contains in it.

Hello everybody.

Can we get user session ID with SilverLight 2 ?
Is it possible at all ?

Thank you.

I don't know what "user session ID" you're referring to,
but I'll answer yes and yes.

Well, I know a session ID from PHP that we could get it with session_id() function.
How many session ids do we have in SL2 ?

None.

Session IDs are a server side thing - Silverlight is a client technology.

You can use ASP.NET sessions through ASP.NET/WCF services...

I'm working just with SL2 (client side) and I wanna get an unique thing for every visitor.
Can we get a something in SL2?
Is there an unique thing in Client side that I could get it with SL2 ?

Would appreciate for helping.

Silverlight runs on the client so it's already "unique".

There's no concept of "visitor" on the client side.

You can inherit the session context in your WCF Services.

Just use:

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class MyService

But remember you will be responsible as well to keep alive that session (maybe service ping every X minutes).

Need ideas for getting data from text file to list view

barker7703-Apr-09 9:48

3-Apr-09 9:48

I have CSV numeric data in a text file, The first row is the column names, the rest is the data.

x,y,z
1.1, 2.1, 0.3
3.2, 4.1, 0.5
0.3, 4.2, 1.1

I want to read this into my application and display it in a list view. I presume I could use C# to open the file and read/parse each line, then add a row to the list view, but I'm wondering if their are WPF (or .Net) tools that can make this job easier.

I'm creating the text file by hand, so if a better format makes it easier, I'm open to ideas there too.

Thanks,

Mitch

This is probably overkill for simple CSV, but I found the following project by Matt Perdeck helpful:

LINQ to CSV library[^]

Even if you don't want to use the LINQ parts of the code you can get some tips for CSV parsing from it.

Hi - can someone help me with this seemingly easy problem? I'm missing something... I'm trying to reference an array from a user control-code behind. The array is defined in main codebehind Page.cs & populated in Page.cs constructor.

Any tips appreciated -- thank you

public partial class Page : UserControl // Page.cs with a string array called dcNames[]
{ public string[] dcNames;
...........

// Page.xaml includes a reference to the user control named: GlobalInfoGridControl.xaml
// User control GlobalInfoGridControl.xaml.cs
public partial class GlobalInfoGridControl : UserControl
{
.......
private void OnSliderValueChanged(object sender, RoutedEventArgs e)
{
Page p = this.Parent as Page;
foreach (string DC in p.dcNames) // method needs to read dcNames[] from Page.cs

I'm looking for a way to programmatically clear all text boxes and combo boxes on my WPF window at the same time. Is there a method for handling this?

I don't know of anything inherent. How about looping for all controls and if it is a textbox\combobox then reset its value? (might have to do it recursively if the controls are contained within an hierarchy.

Enum.GetValues missing

So far, I've been able to find a workaround for any missing functionality in Silverlight, until now. Anyone have any idea how I can get all of the values of an enumeration? And please don't suggest that I iterate from 0 to X and use the IsDefined method - that's simply not a practical solution.

Thanks in advance!

Are you talking develop or run? If it's develop (and assuming Silverlight 2), you'll need Visual Studio 2008, .NET 3.5 and the Silverlight SDK. If it's run, you just need to install the Silverlight control in your browser.

Hehe, Silverlight is a buzzword... first you have to understand what is Silverlight, a quick and dirty definitions (please Ms guys don't read this)... it's like flash but with .net, that is a plugin for IE / FireFox...

You can download Silverlight plugin from the silverlight official site.

To Develop, you will need Visual Studio 2008 + .net fx 3.5 SP1 + SL tools for VS 2008 (you can just go to the silverlight.net getStarted option).
