Alternately:

    BindingOperations.ClearBinding(txtName, TextBox.TextProperty)


When available

    BindingOperations.ClearBinding(txtName, TextBox.TextProperty)

For older SilverLight versions, but not reliable as stated in comments:

    txtName.SetBinding(TextBox.TextProperty, null);


C# 6.0 features enabled
   

    this.btnFinish.ClearBinding(ButtonBase.CommandProperty);

How about:

    this.ClearValue(TextBox.TextProperty);

It&#39;s much cleaner I think ;)

How about just

    txtName.Text = txtName.Text;

You would have to set the value after clearing it anyways. 
This works in SL4 at least.

By default, copying from the command prompt will prompt you to overwrite files that already exist in the target location.

You can add &quot;/Y&quot; to say &quot;Yes to all&quot; replacements.

But how can you say &quot;No to all&quot; ?

In other words, I want to copy everything from one directory that does **not** already exist in the target.

The closest thing I see is the XCOPY argument to only copy things after a specific mod-datetime.

How to say no to all &quot;do you want to overwrite&quot; prompts in a batch file copy?

Passing an undimensioned array to the VB6&#39;s Ubound function will cause an error, so I want to check if it has been dimensioned yet before attempting to check its upper bound.  How do I do this?

I would like to use databinding when displaying data in a TextBox. I&#39;m basically doing like:

     public void ShowRandomObject(IRandomObject randomObject) {
            Binding binding = new Binding {Source = randomObject, Path = new PropertyPath(&quot;Name&quot;)};
            txtName.SetBinding(TextBox.TextProperty, binding);
        }

I can&#39;t seem to find a way to unset the binding. I will be calling this method with a lot of different objects but the TextBox will remain the same. Is there a way to remove the previous binding or is this done automatically when I set the new binding?

I&#39;m trying to write a Mono C# daemon for linux.

I&#39;d like to do a starts and stops of it when its done processing instead of just killing the process.

Does anyone have any examples of this?

Edit: I figured out how to use start-stop-daemon --background in debian, so I think I&#39;ll just use that for now.

Edit: I&#39;m implementing this in java as well and they have this nice addShutdownHook that catches terminating the app. I need to spend a little more time sorting out the dependencies for mono service, or find a way to catch app termination. 

There is the SessionEnd event, but thats only available for services and not console apps

Unless I am missing an obvious built-in method, what is the quickest way to get the *n*th occurrence of a string within a string?

I realize that I could loop the [IndexOf][1] method by updating its start index on each iteration of the loop. But doing it this way seems wasteful to me.

I need to configure a website to access a webservice on another machine, via a proxy.  I can configure the website to use a proxy, but I can&#39;t find a way of specifying the credentials that the proxy requires, is that possible?  Here is my current configuration:

    &lt;defaultProxy useDefaultCredentials=&quot;false&quot;&gt;
    	&lt;proxy usesystemdefault=&quot;true&quot; proxyaddress=&quot;&lt;proxy address&gt;&quot; bypassonlocal=&quot;true&quot; /&gt;
    &lt;/defaultProxy&gt;

I know you can do this via code, but the software the website is running is a closed-source CMS so I can&#39;t do this.

Is there any way to do this?  MSDN isn&#39;t helping me much..

Is it possible to specify proxy credentials in your web.config?

How do I invoke a console application from my .NET application and capture all the output generated in the console?

If I am passing an object to a method, why should I use the ref keyword? Isn&#39;t this the default behaviour anyway?

For example:

    class Program
    {
        static void Main(string[] args)
        {
            TestRef t = new TestRef();
            t.Something = &quot;Foo&quot;;

            DoSomething(t);
            Console.WriteLine(t.Something);
        }

        static public void DoSomething(TestRef t)
        {
            t.Something = &quot;Bar&quot;;
        }
    }


    public class TestRef
    {
        public string Something { get; set; }
    }

The output is &quot;Bar&quot; which means that the object was passed as a reference.


Why use the &#39;ref&#39; keyword when passing an object?

Problem is described and demonstrated on the following links:

- [Paul Stovell  WPF: Blurry Text Rendering  ][1]
- [www.gamedev.net forum][2]
- [Microsoft Connect: WPF text renderer produces badly blurred text on small font sizes][3]

Explanation: [Text Clarity in WPF][4]. This link has font comparison.

I would like to collect all possible solutions for this problem. Microsoft Expression Blend uses WPF but fonts look readable. 

- Dark background as in Microsoft Expression Blend
- Increasing the font size and changing the font (Calibri ... ) [[link]][5]
- Embed windows forms [[link]][6]
- Use GDI+ and/or Windows Forms TextRenderer class to render text to a bitmap, and then render that bitmap as a WPF control. [[link]][7]

Are there any more solutions?

WPF Blurry fonts issue- Solutions

The following code has a simple binding which binds the Text of the TextBlock named MyTextBlock to TextBox&#39;s Text and ToolTip property using the exact same Binding notation:

    &lt;StackPanel&gt;
        &lt;TextBlock x:Name=&quot;MyTextBlock&quot;&gt;Foo Bar&lt;/TextBlock&gt;
        &lt;TextBox    Text=&quot;{Binding ElementName=MyTextBlock, Path=Text, StringFormat=&#39;It is: \{0\}&#39;}&quot;
                 ToolTip=&quot;{Binding ElementName=MyTextBlock, Path=Text, StringFormat=&#39;It is: \{0\}&#39;}&quot; /&gt;
    &lt;/StackPanel&gt;

The binding also uses the [StringFormat property introduced with .NET 3.5 SP1][1] which is working fine for the above Text property but seems to be broken for the ToolTip. The expected result is &quot;It is: Foo Bar&quot; but when you hover over the TextBox, the ToolTip shows only the binding value, not the string formatted value. Any ideas?

WPF binding with StringFormat doesn&#39;t work on ToolTips

When using resources such as brushes, templates and styles in WPF, they can be specified either as StaticResources 

    &lt;Rectangle Fill=&quot;{StaticResource MyBrush}&quot; /&gt;

or as a DynamicResource

    &lt;ItemsControl ItemTemplate=&quot;{DynamicResource MyItemTemplate}&quot;  /&gt;

Most of the times (always?), only one works and the other will throw exception during runtime. But I&#39;d like to know why:

  - What is the main difference. Like memory or performance implications
  - Are there rules in WPF like &quot;brushes are always static&quot; and &quot;templates are always dynamic&quot; etc.?

I **assume** the choice between Static vs Dynamic isn&#39;t as arbitrary as it seems... but I fail to see the pattern.

What&#39;s the difference between StaticResource and DynamicResource in WPF?
