Have a look at the Prism documentation for both 4.x and 2.x here[^].

To use WCF service in c# windows application there is option to add service reference (pass url) and use it.
But i did not find any such option in VC++.
Can you guide me how to use it in VC++.

As the Design and Architecture forum seems to have vanished I will ask the questions here.
We have successfully moved to Silverlight as our UI with WCF driving the data.
We exist exclusively behind the firewall.
We have very tight security policies (no admin, net nazi, firewall between network regions). IT has some serious trust issues 
Am I going to get any benefit from using WPF via clickonce or WPF in a browser.

If you don't need full desktop feature access, then you aren't really going to see any benefits from the user experience point of view.

Full desktop would be nice but fighting the trust battle with IT would be irritating. I was more interested in whether System.Data being available to the UI makes a difference, Do you serialize datatables or pass collections as with Silverlight.
We do a lot of small file up/download, passing bits of data around and full trust would be useful there. Having a user try and upload 100mb over the WAN would get me sacked. With SL/WCF there are built in limits that I'm not sure apply with WPF.

I'm sorry but I don't understand your question.
If you have already moved to Silverlight, then why are you wondering about using WPF via clickonce or in a browser?
|
|
|
|
|
Well I feel like I may be missing out, WPF has a larger feature set than Silverlight but it seems they are all around the trust issues.
Really I'm looking for a benefit comparison, there are a number of feature comparisons that seem to point out limitations in Silverlight and how to get around them, out of browser and elevated trust mainly.

Have a look at this guidance[^]. I have found it very useful.
Maybe it can help you too.
[Unfortunately its a little old now - 2009 release]

Thanks, a little light reading - 70 pages, still it does look interesting. I'd be surprised if the fundamental differences have changed with SL5

Hello,
I have a button which has 2 labels. I want the labels foreground to be black on mouse over button and white when mouse is not over button.
I used this :
<Style TargetType="{x:Type Label}" >
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Foreground" Value="Black"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="false">
<Setter Property="Foreground" Value="White"/>
</Trigger>
</Style.Triggers>
</Style>
But the thing is that label foreground is changed only when i am over the label. so one label is black and second is white.
How can i solve this so when mouse is over the button, it's children labels will use this style?

You only need to supply one trigger. What you do is define the standard style, and as you have a boolean condition, the other condition will be applied when appropriate. Here's what I mean:
<Style TargetType="{x:Type Label}">
<Setter Property="Foreground" Value="Black" />
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="False">
<Setter Property="Foreground" Value="White" />
</Trigger>
</Style.Triggers>
</Style>As you can see, you have a default style which gets overriden by the trigger, and when the trigger no longer applies, it reverts back to the default style.

Right but that's not what i meant.
I meant that i have a button with 2 labels. But only one of them becomes black when mouse is over one of them , and second label stays white. i want a functionality that when mouse is over the button, both labels will be black.
|

Ahh, I see. Well, you need to give the label you are interested in a name, and use TargetName in your style trigger setter to change the style. The actual style you have as the main style should be Button not Label.
|
|
|
|
|
Your trigger is applied to a label, not to the button. Because "IsMouseOver" is a property of an individual label, the other label on the button is not influenced.
Could you also provide the code of your button?

Hello,
I have a button which opens a popup. In my xaml code behind i use:
private void dropDownbtn_Click(object sender, RoutedEventArgs e)
{
MenuPopUp.StaysOpen = true;
MenuPopUp.IsOpen = true;
MenuPopUp.StaysOpen = false;
}
The thing is that i want to put this code into xaml using event trigger (click on button) and setter with binding element as menuPopUp and set it's properties.
Can i do it in xaml? i mean set the same property twice (once true and once false)? I mean for the statysOpen property.
BTW, i am doing this because otherwise popup will be opened and closed automatically on button click so popup will never be shown.

Hi
In my WPF application i'm using an Entity Data Model to access data.
Whem my application start i load the connectionstring from a file and i pass it to the EntityDataModel trough its constructor.
SuiteStoreEntites issEntities = new SuiteStoreEntities(connectString);
The connection string parameter is :
metadata=res://*/Data.SuiteStoreModel.csdl|res://*/Data.SuiteStoreModel.ssdl|res://*/Data.SuiteStoreModel.msl;provider=System.Data.SqlClient;provider connection string="Data Source=.\\SQLEXPRESS;Initial Catalog=SuiteStore;Integrated Security=True;MultipleActiveResultSets=True;Application Name=EntityFramework"
And i get the following error in the EntityDataModel's designer: Argument Exception Occured Keyword 'data source' is not supported.
public SuiteStoreEntities(string connectionString) : base(connectionString, "SuiteStoreEntities")
{ ... }
<pre>
<div class="signature">
</div>
|
|
|
|
|
in this statement.
connection string=;"Data Source=.\\SQLEXPRESS remove the ";".
connection string="Data Source=.\\SQLEXPRESS
To build a correct connection string look at this link.
connection string="Data Source=.\\SQLEXPRESS[^]

How I can understand how the principle of binding in WPF?

One of the easiest ways to get started in MVVM is with this[^] article. You can also get MVVM In The Box[^] training.
