Pages are intended for use in Navigation applications (usually with Back and Forward buttons, e.g. Internet Explorer). Pages must be hosted in a NavigationWindow or a Frame

Windows are just normal WPF application Windows, but can host Pages via a Frame container


A Window is always shown independently, A Page is intended to be shown inside a Frame or inside a NavigationWindow. 



Page Control can be contained in Window Control but vice versa is not possible

You can use Page control within the Window control using NavigationWindow and Frame controls. Window is the root control that must be used to hold/host other controls (e.g. Button) as container. Page is a control which can be hosted in other container controls like NavigationWindow or Frame. Page control has its own goal to serve like other controls (e.g. Button). Page is to create browser like applications. So if you host Page in NavigationWindow, you will get the navigation implementation built-in. Pages are intended for use in Navigation applications (usually with Back and Forward buttons, e.g. Internet Explorer). 

WPF provides support for browser style navigation inside standalone application using Page class. User can create multiple pages, navigate between those pages along with data.There are multiple ways available to Navigate through one page to another page.



I am wondering, What is the proper way for inserting PHP variables into a string?
&lt;br/&gt;&lt;br/&gt;
**This way:**&lt;br/&gt;

    echo &quot;Welcome &quot;.$name.&quot;!&quot;

**Or this way:**&lt;br/&gt;

    echo &quot;Welcome $name!&quot;
Both of these methods work in my `PHP v5.3.5`. The latter is shorter and simpler but I&#39;m not sure if the first is better formatting or accepted as more proper.

I have a timestamp stored in a session (1299446702).

How can I convert that to a readable date/time in PHP? I have tried srttotime, etc. to no avail.

I&#39;ve got a WCF Service running on my local IIS server. I&#39;ve added it as a service reference to a C# Website Project and it adds fine and generates the proxy classes automatically.

However, when I try and call any of the service contracts, I get the following error:

&gt; **Description:** An unhandled exception occurred during the
&gt; execution of the current web  request.
&gt; Please review the stack trace for more
&gt; information about the error and where

Is there a shorter way to write the following? (Something that would check for null without explicitly writing `!= null`)

    from item in list 
    where item.MyProperty != null 
    select item.MyProperty

In LINQ, select all values of property X where X != null

I have this attribute in my view model:

    [DataType(DataType.DateTime)]
    public DateTime? StartDate { get; set; }

If I want to display the date, or populate a textbox with the date, I have these:

    &lt;%: Model.StartDate %&gt;

    &lt;%: Html.TextBoxFor(m =&gt; m.StartDate) %&gt;

Whenever the date is displayed, it&#39;s displayed like: **01/01/2011 12:00:00 AM**

But I&#39;d like to only display **01/01/2011**

Is there a way to apply a display format with data annotations? I don&#39;t want to have to go to every instance where I display a date, and add some code to format it.

Assign format of DateTime with data annotations?

    //     created directly from the executable file. The default is true.
    [DefaultValue(true)]
    [MonitoringDescription(&quot;ProcessUseShellExecute&quot;)]
    [NotifyParentProperty(true)]
    public bool UseShellExecute { get; set; }


If we spawn a new process, when do we need to set UseShellExecute  to True?

When do we need to set ProcessStartInfo.UseShellExecute to True?

I have many file types: pdf, tiff, jpeg, bmp. etc.
My question is how can I change file extension?
I tried this:

    my file= c:/my documents/my images/cars/a.jpg;
    string extension = Path.GetExtension(myffile);
    myfile.replace(extension,&quot;.Jpeg&quot;);

No matter what type of file it is, the format I specify must be with the file name. But it does not work. I get file path from browser like `c:\..\..\a.jpg`, and the file format is `a.jpeg`. So, when I try to delete it, it gives me an error: `Cannot find the file on specified path&#39;`. So, I am thinking it has something to do with the file extension that does not match. So, I am trying to convert `.jpg` to `.jpeg` and delete the file then.

simple question: How can I set a padding on a dataGridCell in WPF?
(either one at a time or on all cells, I don&#39;t care)

I have tried using the `DataGrid.CellStyle` property by adding a setter on the `DataGridCell.Padding` property as well as using the `DataGridColumn.CellStyle` property in the same way with no effect.

I also tried using the `DataGridColumn.ElementStyle` property with no more luck.

I&#39;m kind of stuck there, has anyone managed to get a padding applied on a dataGridCell?

NB: I&#39;ll add that no, I cannot use transparent borders to do this, since I already use the border properties for something else. I also cannot use the margin property (which seems to work, surprisingly enough) as I use the background property and I don&#39;t want any &quot;blank&quot; space between my cells.

How do I achieve formatting of a text inside a `TextBlock` control in my WPF application?

e.g.: I would like to have certain words in bold, others in italic, and some in different colors, like this example:

![enter image description here][1]

The reason behind my question is this actual problem:

    lblcolorfrom.Content = &quot;Colour From: &quot; + colourChange.ElementAt(3).Value.ToUpper();

I would like the second part of the string to be bold, and I know that I could use two controls (Labels, TextBlocks, etc.) but I&#39;d rather not, due the vast amount of controls already in use.

Formatting text in a TextBlock

I want to create some extended Binding-Markup-Extension, which behaves just like a normal WPF-Binding but does some things more (use different defaults, maybe add some behavior, etc.).
Code looks like this:

    public class CustomBindingExtension : Binding
    {
      .. some extra properties and maybe overrides ...
    }

It all works fine including XAML-intellisense, except I just can&#39;t make Resharper resolve my Binding-Path correctly.
I.e.: using this code I can [Strg]+Click on &#39;CurrentText&#39; and Resharper lets vs2010 navigate to the code defining the CurrentText-Property.
   
    &lt;UserControl x:Name=&quot;uc&quot; ...&gt;
      &lt;TextBox Text=&quot;{Binding ViewModel.CurrentText, ElementName=uc}&quot; /&gt;
    &lt;/UserControl&gt;

But using **my** binding, which works correctly at runtime, I just get a Tooltip when hovering &#39;CurrentText&#39; telling me it is some &#39;MS.Internal.Design.Metadata.ReflectionTypeNode&#39;, and no navigation via [Strg]+Click.

    &lt;UserControl x:Name=&quot;uc&quot; ...&gt;
      &lt;TextBox Text=&quot;{util:CustomBinding ViewModel.CurrentText, ElementName=uc}&quot; /&gt;
    &lt;/UserControl&gt;

I tried the following things:
&lt;li&gt;Derive from Binding&lt;/li&gt;
&lt;li&gt;Derive from &lt;a href=&quot;http://www.hardcodet.net/2008/04/wpf-custom-binding-class&quot;&gt;BindingDecoratorBase&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;Leave out the &#39;Extension&#39; suffix for my CustomBinding-class&lt;/li&gt;
&lt;li&gt;put the Markup-Extension in a separate assembly&lt;/li&gt;
&lt;li&gt;Use ConstructorArgumentAttribute&lt;/li&gt;
&lt;li&gt;Property of type string and type PropertyPath for the Path-Property&lt;/li&gt;

I also looked at the original classes Binding and BindingBase, but could not find any more difference to my code.
Any ideas what should help here?
Or is this just a special treatment of the Binding-MarkupExtension which I can in no way get for my own MarkupExtensions?

Update 16.03.2011: Might also be bug or deficiency of Resharper, Jetbrains is investigating the issue: http://youtrack.jetbrains.net/issue/RSRP-230607

Update 10.12.2013: Meanwhile, the feature seems to be working (with R# 7.1.3, maybe also earlier versions), I actually use the approach with the BindingDecoratorBase and I like it a lot.
Maybe it only works, if your MarkupExtension ends on &#39;Binding&#39;, but mine does, so I am happy.
