In project -&gt; properties change &quot;startup object&quot; to the new namespace.

![Select Startup Object][1]


  [1]: http://i.stack.imgur.com/1s8zA.png

You should rename through the &quot;Refаctor&quot; feature of Visual Studio.

As Mausimo says you need to select the &#39;Startup object&#39; in Project -&gt; References, however I was finding that the new namespace was not being shown here; I could only select the old namespace or &#39;(Not set)&#39;. If you find the same then it appears VS (this is on 2013) does not pick up the change immediately, restart VS and you can then select the class under the new namespace.



Is there any faster way to access the frame buffer than using glReadPixels? I would need read-only access to a small rectangular rendering area in the frame buffer to process the data further in CPU. Performance is important because I have to perform this operation repeatedly. I have searched the web and found some approach like using Pixel Buffer Object and glMapBuffer but it seems that OpenGL ES 2.0 does not support them.

I am trying to develop a very simple client / server where the client converts a file to bytes, sends it to the server, and then converts the bytes back in to a file. 

Currently the program just creates an empty file. I&#39;m not a fantastic Java developer so any help much appreciated.

This is the server part that receives what the client sends.

    ServerSocket serverSocket = null;

        serverSocket = new ServerSocket(4444);


        Socket socket = null;
        socket = serverSocket.accept();

        DataOutputStream out = new DataOutputStream(new BufferedOutputStream(socket.getOutputStream()));
        DataInputStream in = new DataInputStream(new BufferedInputStream(socket.getInputStream()));
        byte[] bytes = new byte[1024];

        in.read(bytes);
        System.out.println(bytes);

        FileOutputStream fos = new FileOutputStream(&quot;C:\\test2.xml&quot;);
        fos.write(bytes);

And here is the client part

    Socket socket = null;
        DataOutputStream out = null;
        DataInputStream in = null;
        String host = &quot;127.0.0.1&quot;;     
        
        socket = new Socket(host, 4444);
        out = new DataOutputStream(new BufferedOutputStream(socket.getOutputStream()));
        in = new DataInputStream(new BufferedInputStream(socket.getInputStream()));

        File file = new File(&quot;C:\\test.xml&quot;);
        //InputStream is = new FileInputStream(file);
        // Get the size of the file
        long length = file.length();
        if (length &gt; Integer.MAX_VALUE) {
            System.out.println(&quot;File is too large.&quot;);
        }
        byte[] bytes = new byte[(int) length];
        
        //out.write(bytes);
        System.out.println(bytes);

        out.close();
        in.close();
        socket.close();

I have a C# app that had the default namespace `WindowsFormsApplication1`.

I decided that I would like to use a different namespace so I renamed `WindowsFormsApplication1`. Now when I compile I get the error: 

&gt; Could not find &#39;WindowsFormsApplication1.Program&#39; specified for Main
&gt; method.

To rename the namespace I highlighted the namespace in a file and hit F2.

How do I resolve this and change the actual namespace through out the project? 

I am using Visual C# 2010 Express.

I am using Parallel.ForEach and I am doing some database updates, now without setting MaxDegreeOfParallelism , a dual core processor machine results in sql client timeouts, where else quad core processor machine somehow does not timeout.

Now I have no control over what kind of processor cores are available where my code runs, but is there some settings I can change with MaxDegreeOfParallelism that will probably run less operations simultaneously and not result in timeouts?

I can increase timeouts but it isnt a good solution, if on lower CPU I can process less operations simultaneously, that will put less load on cpu.

Ok I have read all other posts and MSDN too, but will setting MaxDegreeOfParallelism to lower value make my quad core machines suffer?

For example, is there anyway to do something like, if CPU has two cores, then use 20, if CPU has four cores then 40?

What does MaxDegreeOfParallelism do?

Neither of these work:

    _uiDispatcher.Invoke(() =&gt; { });
    _uiDispatcher.Invoke(delegate() { });

All I want to do is Invoke an inline method on my main UI thread. So I called this on the main thread:

    _uiDispatcher = Dispatcher.CurrentDispatcher;

And now I want to execute some code on that thread from another thread. How do I do it? Am I using the wrong syntax?

Note that this is *not* a WPF application; I&#39;ve referenced `WindowsBase` so I could get access to the `Dispatcher` class.

I am interested in writing a generic Intellisense enabled editor for SQL and C# (et al. if possible!). I would like to do this in C# as an overridden or extended WPF richTextBox-type control. I know there are many example projects available and I have implemented a _basic_ version of my own; but most of the examples that I have come across (and indeed my own) are just that, _basic_. 

A couple of code examples are: 

1. [DIY Intellisense By yetanotherchris](http://www.codeproject.com/Articles/5839/DIY-Intellisense) 

2. [CodeTextBox - another RichTextBox control with syntax highlighting and Intellisense By Tamas Honfi](http://www.codeproject.com/Articles/29154/CodeTextBox-another-RichTextBox-control-with-synta)

I have however, found a great example of an SQL editor with Intellisense [QueryCommander SQL Editor By Mikael H&#229;kansson](http://www.codeproject.com/Articles/9465/QueryCommander-SQL-Editor) which seems to work well. Microsoft must use a XML library of command keywords, but my question is: How (in detail) do Microsoft implement their Intellisense (as-you-type Intellisense) and how hard would it be for me to create my own of the same standard?

_Edit A: A year on and I have managed to develop my own editor control with basic intellisense mainly for my own &quot;enjoyment&quot;. I thought I would come back provide a list of freely available .NET projects that helped me with my own development and can be used out-of-the-box and free of charge:_

1. [ICSharpCode (WinForms)](http://www.codeproject.com/Articles/30936/Using-ICSharpCode-TextEditor)

1. _[RoslynPAD](http://arbel.net/2013/05/11/roslynpad/) is cool!_

_Edit C: 2 years+ on from the question, I have found the following projects, both using WPF and backed by AvalonEdit._

1. [CodeCompletion for AvalonEdit](https://github.com/lukebuehler/NRefactory-Completion-Sample) using NRefactory. This project is really nice and has a full implementation of intellisense using NRefactory.

2. [ScriptCS](https://github.com/scriptcs/scriptcs) ScriptCS makes it easy to write and execute C# with a simple text editor.

I&#39;m toying with the idea of writing a JIT compiler and am just wondering if it is even theoretically possible to write the whole thing in managed code. In particular, once you&#39;ve generated assembler into a byte array how do you jump into it to begin execution?

I began organizing my code to day into seperarate .cs files, and in order to allow the methods that work with the UI to continue to do so I would create the .cs code under the same namespace and public partial class name so the methods could be inter-operable. 

My header look like this in four files, including my main core file that calls: 

    public shell()
    {
    InitializeComponent(); 
    }

    using System.Windows.Forms;

Now when I try to debug/preview my application (BTW this is a Windows Application within Visual Studio 2010 Express) I get this error message:

&gt;    Does not contain a static &#39;main&#39; method suitable for an entry point

I looked in the application properties in Application-&gt;Startup object, but it offers me no options. How can I inform the application to begin at the .cs file that has my InitializeComponent(); command? 

 - I&#39;ve looked around so far without a solution.
 - The properties on each .cs file are set to &#39;Compile&#39;.
 - I do not see an App.xaml file in my Solutions explorer but I do see a app.config file.


I&#39;m still very new and this is my first attempt at an organizing method with c# code.

I recently discovered that even while logged into my personal laptop as an administrator, Visual Studio does not run in administrator mode and you need to explicitly use *Run As Administrator*.

Is there a way to make it run as an administrator by default, other than creating a shortcut, etc.?

I am creating a Prism Project Template, and the template works great. But after I create a project with the template some of the files look like this:

![Bad References][1]

**Despite appearances, everything is just fine.**

If I do a *Rebuild All* I see that the solution builds with no errors:

![Rebuilt][2]

But the rebuild all does not get rid of the &quot;errors&quot; that are showing in the editor window. (Note that the actual error window does not show any errors.)

I can clean, rebuild, close and open files, and it will not fix the highlighting.

However, **if I close the solution and re-open it, all is well**:

![Works After Reload][3]

**My Question:**

Ideally there would be a way for my template or my IWizard to tell ReSharper to reload the references for the highlighting.

I know I can turn ReSharper [off and then on again][4] and that will fix it, but I would rather not do that.

Is there a ReSharper command that just refreshes this stuff?

How to make ReSharper re-evaluate its assembly reference highlighting

I would like to understand the purpose of targetNamespace as used both in XML Schema and in WSDL. In fact, to keep things simple, let&#39;s limit this question to XML Schema.

I feel like I fully understand the notion of (simple) XML namespaces. By convention we use URI/URLs, but we could use any string, which we then assign to a prefix for reuse by XML nodes and attributes, or use simply as the default namespace for the scope at hand. So far, so good ?

Now enters XML Schema. For some reason the inventors of XML Schema felt the notion of simple namespaces wasn&#39;t enough and they had to introduce the targetNamespace. My question is : what significant benefit does a targetNamespace introduce that couldn&#39;t be provided by a normal XML namespace ? If an XML document references a xsd document, either by schemaLocation or with an import statement, in either case I give the path to the actual xsd document being referenced. This is what uniquely defines the Schema I want to refer to. If in addition I want to bind this Schema to a particular namespace in my referencing document, why should I be obliged to replicate the precise targetNamespace already defined in the XML Schema I am referencing? Why couldn&#39;t I simply redefine this namespace however I want within the XML document in which this namespace will be used to refer to that particular XML Schema document I want to reference ?

Update:

To give an example, if I have the following in an XML instance document:

    &lt;p:Person
       xmlns:p=&quot;http://contoso.com/People&quot;
       xmlns:v=&quot;http://contoso.com/Vehicles&quot;
       xmlns:xsi=&quot;http://www.w3.org/2001/XMLSchema-instance&quot;
       xsi:schemaLocation=
        &quot;http://contoso.com/schemas/Vehicles
         http://contoso.com/schemas/vehicles.xsd
         http://contoso.com/schemas/People
         http://contoso.com/schemas/people.xsd&quot;&gt;
       &lt;name&gt;John&lt;/name&gt;
       &lt;age&gt;28&lt;/age&gt;
       &lt;height&gt;59&lt;/height&gt;
       &lt;v:Vehicle&gt;
          &lt;color&gt;Red&lt;/color&gt;
          &lt;wheels&gt;4&lt;/wheels&gt;
          &lt;seats&gt;2&lt;/seats&gt;
       &lt;/v:Vehicle&gt;
    &lt;/p:Person&gt;

Why does e.g. the people.xsd Schema need to define a targetNamespace which is &quot;http://contoso.com/schemas/People&quot;? Why do we need the targetNamespace definition in the xsd document at all? It seems to me all you have to gain from the namespace part of the schemaLocation is already contained in the XML instance document. What is the benefit of enforcing the existence of a targetNamespace with equal value over in the xsd document ?

Follow-up question to Paul&#39;s answer:

Can you give me a concrete example where such &quot;clashes&quot; between xsd element names becomes apparent and that would explain the need for targetNamespace ?

-----------

Ok, here&#39;s an attempt to answer my own question. Let me know if it seems coherent to you. Looking at the examples on the page linked by Paul helped me.

If we take the XML instance example in the original question above, we have two references to the definition of the vehicle element. One is explicit and visible in the XML instance document itself, but we must also imagine that the person.xsd XML Schema references the same vehicle definition again as an allowed child element of person. If we were to use normal namespaces where each document were allowed to define its own namespace for vehicle, how would we know that the XML instance is referencing the same XML Schema definition for vehicle as is the person.xsd ? The only way is by enforcing a concept of namespace which is stricter than the original simple one and which must be written exactly the same way across multiple documents.

If I wasn&#39;t writing this on a tablet I would provide a code example, but here I will just attempt to describe the example I have in mind.

Imagine that we have two different XML Schema definitions for a vehicle element. location1/vehicles.xsd would contain the definition that validates the example from the question of this post (containing color, wheels, and seats child elements), whereas location2/vehicles.xsd would contain an entirely different definition for a vehicle element, (say, with child elements year, model, and volume). Now, if the XML instance document refers to the location1 Schema, as is the case in the example above, but person.xsd says that the person element can contain a vehicle child element of the type defined in the location2 Schema, then without the notion of a targetNamespace, the XML instance would validate, even though it clearly doesn&#39;t have the right kind of vehicle as a child element of its person element.

Target namespaces then help us make sure that if two different documents are referencing the same third XML Schema, that they are both in deed referencing the same Schema and not just a Schema that contains elements that are similar, but not identical to one another...

Does that make any sense ?

Why do we need targetNamespace?

I saw usages of these two phrases: global scope and global namespace. What is the difference between them?

Global scope vs global namespace

I am having a little trouble with namespaces and the `use` statements.

I have three files: `ShapeInterface.php`, `Shape.php` and `Circle.php`.

I am trying to do this using relative paths so I have put this in all of the classes:
    
    namespace Shape; 
    
In my circle class I have the following:

    namespace Shape;
    //use Shape;
    //use ShapeInterface;
    
    include &#39;Shape.php&#39;;
    include &#39;ShapeInterface.php&#39;;    

    class Circle extends Shape implements ShapeInterface{ ....

If I use the `include` statements I get no errors. If I try the `use` statements I get:

&gt; Fatal error: Class &#39;Shape\Shape&#39; not found in
&gt; /Users/shawn/Documents/work/sites/workspace/shape/Circle.php on line 8

Could someone please give me a little guidance on the issue?

PHP namespaces and &quot;use&quot;

Consider a pair of two source files: an interface declaration file (`*.h` or `*.hpp`) and its implementation file (`*.cpp`).

Let the `*.h` file be like the following:

    namespace MyNamespace {
      class MyClass {
      public:
        int foo();
      };
    }

I have seen two different practices for using namespaces in source files:

`*.cpp` showing practice #1:

    #include &quot;MyClass.h&quot;
    using namespace MyNamespace;
    
    int MyClass::foo() { ... }

`*.cpp` showing practice #2:

    #include &quot;MyClass.h&quot;
    namespace MyNamespace {
    
      int MyClass::foo() { ... }
    
    }

**My question:** Are there any differences between these two practices and is one considered better than the other?

C++: Namespaces -- How to use in header and source files correctly?

My understanding is that `string` is a member of the `std` namespace, so why does the following occur?

    #include &lt;iostream&gt;
    
    int main()
    {
    	using namespace std;
    
    	string myString = &quot;Press ENTER to quit program!&quot;;
    	cout &lt;&lt; &quot;Come up and C++ me some time.&quot; &lt;&lt; endl;
    	printf(&quot;Follow this command: %s&quot;, myString);
    	cin.get();
    
    	return 0;
    }


![enter image description here][2]

Each time the program runs, `myString` prints a seemingly random string of 3 characters, such as in the output above.
