Hi All,
I was using following packages/namespaces in Flash project using ActionsScript3 language.
import mx.messaging.Consumer;
import mx.messaging.MessageAgent;
import mx.messaging.Producer;
import mx.rpc.AbstractService;
import mx.rpc.http.HTTPService;
import mx.rpc.remoting.RemoteObject;
import mx.rpc.soap.WebService;
Now i want to covert my project in to Microsoft Silverlight. Can anybody suggest me which are the alternatives namespaces available in .Net Framework class library for Silverlight.
Thanks in Advance

Hello Atul,
The most of here are not familiar with ActionScript or Flash. So, we are not so sure about those namespace.. What you can do is that you can tell us what you want to do. We may probably suggest you something..

How to create a TreeViewItem outside the main thread?
I use BeignInvoke called from the main thread to add it to a TreeView, but for performance issues I want to use more threads in multiple-core machines for creating TreeView items (loading their content may take some time).
Any help appreciated.

The setting:
In my application I have a viewing area:
<Border x:Name="contentArea" BorderBrush="Black" BorderThickness="1" Margin="10" />
And, triggered by user action I get passed XAML fragment to put in, such as:
<wpf:ControlTemplate>
<wpf:Frame Source="http://music.controlability.com.au/player"/>
</wpf:ControlTemplate>
then I call LoadContent() on these ControlTemplate (which, in this particular case, create a frame loading a flash music player)
then I set
UIElement ui = GetUI(item);
contentArea.Child = ui;
where item is the XAML fragment originated ControlTemplate and contentArea is the border previously mentioned.
(and GetUI() just call FrameworkTemplate.LoadContent())
The problem:
Now I expect the content to be garbage collected when replaced by another content. Indeed it works quite well with my own objects.
Now the problem is with this Frame with a Flash music player, it doesn't get collected when it's removed from the UI and the music keeps playing!
What can I do?
I have no reference to it, I have no event registered with it, I don't even know it's a frame, as far as I know it's just a ControlTemplate!

Iam trying to develop a Treeview where the user can only view childnodes of a node only one at a time. eg. Suppose the user clicks on Node 1 its childnodes shall be visible, the moment he clicks on Node2, only Node2's child nodes shall be visible, Node1's childnodes would have collapsed. My questions are ;
i) Is it possible to do so using only XAML (No code in VB to be written)
ii)If possible where could I get articles/guidelines/manuals etc. on this subject.
Best Wishes ....... ARIJIT

Hi! I have written the following text in my WPF application. But it is not working. When I click on the hyperlink nothing happens.
<Hyperlink NavigateUri="http://www.yahoo.com">
<Span Foreground="#FF0000FF" TextDecorations="Underline">
<Run Text="Yahoo"/></Span>
</Hyperlink>
Is any other way to give links on text. Actually I want to link folders and files of harddisk with my application not websites.

You need to handle the Click event and navigate to the URL.
I use the below function. strFileName can be a file name, or URL and the O/S will navigate the user to the web page.
Public Class UtilityHelpers
#Region " Methods "
Public Shared Sub StartProcessWithFileName(ByVal strFileName As String)
'Start a process : http://dotnet.mvps.org/dotnet/faqs/?id=openfileappwebpage&lang=en
Dim psi As New System.Diagnostics.ProcessStartInfo
psi.FileName = strFileName
psi.UseShellExecute = True
System.Diagnostics.Process.Start(psi)
End Sub
#End Region

HI,
I am using update panel in my application.but i am facing one issue.
I have one page for new enrolment of members, and i have two user controls Step1.ascx and Step2.ascx. My functionality is that at a time olny one control is visible on the page and other will be hide. for eg when user fills all fields in step1 and press next button then step2.acsx will be be visible true and user Step1.ascx will be visible false. all this happening at postback.
both control is under update panel to avaid post back during change of visibility.
On Step1.ascx i have one javascript variable var_pageName and its value is "Step1".
I want to update this value during post back to "Step2" when Step2 user control visible is true and vise versa. but the problem i am facing is javascript value is not updating during postback. I had tried this with scriptManager.RegisterClientScriptBlock and also with scriptManager.RegisterStartupScriptBlock by palacing it on both Usercontrol level and also on page level.
Please help as this is very urgent.

When I load and show an image using WPF I get some size related problems. On many images (I think all) the image is too large than when I open it in Pain, Paint.NET or Vista's Photo Gallery.
I can circumvent it by setting the DPI. For instance if I load and show an image (in WPF) with a DPI of 72 the image is larger than it should be. If I then set the image's DPI to 96 (which is my screen's DPI) it is shown correct.
Does this has something to do with WPF device independent pixels, and what would be the correct way to handle it?

Thanks for that link - that was quite interesting.
I take it to mean that every time I load a picture I should set the DpiX and DpiY to 96. It does work correctly, but it seems a bit strange I must say.

This is all in the realm of WPF being DPI independent.
Have you checked out <Viewbox>?

Hi All,
If your releasing a WPF application to the wilds this is a big consideration as its going to need users to download and install the framework. Does anyone have any info on how widely installed it is already?
Do you think MS will make it a prerequisite Windows Update anytime soon?
Cheers,
Jammer

3.0 is the standard framework currently used with Windows Vista and is considered an optional download for WinXP users with SP2. Although it would be nice for .NET 3.5+ to be included in Windows Update I do not forsee it happening.

I'm looking for the best way to render a map in WPF.
The map is 29952x11520 pixels, hence it is too large to simply store into memory. It is divided into blocks of 32x32 pixels, and these blocks are compressed, but can be decompressed to draw the blocks when necessary.
The map should be scrollable.
What is the best way to allow the map to scroll quickly, without taking up over a gigabyte of memory?

Silverlight has the MultiScaleImage aka DeepZoom which would do all the hard work for you, this is not available in WPF and I'm not sure if/when it will be added. If you want to do it in WPF you'll have to do it yourself, maybe the projects below could help although they use different technologies. Depending on whether you need to support zooming you may need to have different sets of tiles depending on the zoom level, even though the image would be cut into many pieces to zoom out all the way you would still need every tile. You might want to research image formats that support progressive loading, It would seem using Silverlight would be your best bet.

The normal way of doing this is to load the tiles around the area you are viewing and, when you scroll, load in the tiles you need in that particular direction.
