It is called `AcceptButton` now on the form; set that to the button that will be the default button.  
Refer to [Form.AcceptButton Property][1]

I think you want the &quot;AcceptButton&quot; property at the FORM level...   That will expose a combobox of available controls on your form, then select your &quot;button&quot; you want to use as the &quot;Default&quot; button on enter.

In addition to Form.AcceptButton property the &quot;OK&quot; button must have the TabOrder property set to 0 and all other controls within the form should have a TabOrder &gt;0.

This can be done using a form resouce contruction kit or by code eg.
buttonOK.TabOrder = 0;

I have noticed severally how there is a mix up when it comes to an active button and an accept button. I just came out of it. So, I just thought I add a little option to the answers already given. Obviously, the best answer is;

`this.AcceptButton = AcceptButton;`

However, if you wish to have the button as an active control, this is what you do;

`this.ActiveControl = OkButton;`

I hope it is helpful to anyone searching.

I have a BroadcastReceiver which is called every so often, and I have noticed many people use 

    android: process =&quot;:remote&quot; 

in their receiver. Mine is used to check a few things and if the conditions match then activate an alarm. My question is should I use the line I had posted above in my manifest? And if so what are the benefits of doing so?

I did not realize that: &#39;have a web.config in a separate class library and&#39; was reading the web.config app setting from different web application.

I am using VS2010 target framework 3.5

I don&#39;t know what is wrong here but I am getting `null` when I try to get `ConfigurationManager.AppSettings[&quot;StoreId&quot;];`

    private string _storeid = GetStoreId;

    public static string GetStoreId
    {
        get
        {
            return ConfigurationManager.AppSettings[&quot;StoreId&quot;];
        }
    }

**web.config:**

    &lt;appSettings&gt;
        &lt;add key=&quot;StoreId&quot; value=&quot;123&quot; /&gt;
    &lt;/appSettings&gt;

I want to write a new templating language, and I want Visual Studio to &quot;support&quot; it. What I need to know is:

1. **How do I parse my new language?**  
Given some code in my new template language, how do I translate it into HTML? Right now I&#39;m using regular expressions to parse it token by token, but I don&#39;t think this is going to scale very well as the language gets more complicated, and there&#39;s no error checking. I&#39;ve heard of ANTLR but never used it. Would that be the right tool for this job, or is there perhaps something simpler? Ideally I&#39;d like to send any syntax errors to the error window with as much information as possible (line #, type of error) like other languages do.
2. **How do I create a new file type for Visual Studio?**
3. **How do I get syntax highlighting?**  
Can I use the same parser I created in step 1, or is this something entirely different?
4. **How do I get Intellisense?**

I&#39;d prefer to write my parser in C#.

How to create a new language for use in Visual Studio

I have a console application and what I&#39;m trying to do is that every time the appllication runs, the date and time is sent to a table within my database. 

The table structure is like so:

    FTPRuns
    
    ID int
    
    Last Run datetime

Simple enough. 

I&#39;ve updated the model.edmx within my application also to reflect this new change, However now I am getting the below error and I&#39;m not entirely sure what it means.


&gt; Error 3002: Problem in mapping
&gt; fragments starting at line
&gt; 1330:Potential runtime violation of
&gt; table FTPRuns&#39;s keys (FTPRuns.ID):
&gt; Columns (FTPRuns.ID) are mapped to
&gt; EntitySet FTPRuns&#39;s properties
&gt; (FTPRuns.ID) on the conceptual side
&gt; but they do not form the EntitySet&#39;s
&gt; key properties (FTPRuns.ID,
&gt; FTPRuns.LastRun).

Here is the snippet of code that I use to update the database also:

     using (ModelContainer ctn = new ModelContainer())
                {
                    try
                    {
                        FTPRun ftp = new FTPRun
                        {
                            LastRun = DateTime.Now
                        };
    
                        ctn.FTPRuns.AddObject(ftp);
    
                        int changes = ctn.SaveChanges();
    
                        Console.WriteLine(changes.ToString() + &quot; Changes saved&quot;);
                        Console.WriteLine(&quot;The LastRun Date Has Been Updated&quot;);
                    }
                    catch (InvalidOperationException ex)
                    {
                         Console.WriteLine(ex.ToString());
                    }
                }

If anyone can help me I&#39;d be very grateful :)

thanks.

I never seem to understand why we need delegates?
I know they are immutable reference types that hold reference of a method but why can&#39;t we just call the method directly, instead of calling it via a delegate?

Thanks

I need to change the icon in the application I am working on. But simply browsing for other icons from the project property tab -&gt; *Application* -&gt; *Icon*, it is not getting the icons stored on the desktop..

In VS2010, I noticed that the &quot;output window&quot; is shown every time we compile the solution, even if we have had close it.

In VS2008, that wasn&#39;t the case. I don&#39;t mind this output window. I prefer looking at the &quot;Error window&quot; only, and only if it is necessary. In VS2008, it was perfect.

My application needs to talk to a web service that hasn&#39;t got an online WSDL definition. The developers however supplied me with a WSDL file.

With a public WSDL Visual Studio can generate this code for me using the Service Reference wizard. But it doesn&#39;t seem to work without a public WSDL.

How do I generate the code for talking to this web service using this WSDL file?

When using Visual Studio 2008 and debugging my unit tests... sometimes the debugger works fine. However very often after modifying some code then clicking &quot;Debug Unit Test&quot; Visual Studio will fail to hit the breakpoints in the code. The debugger basically hangs and eventually the tests runs with the new code anyway, but never stops to let me see what is going on.

I&#39;m assuming this has something to do with some type of assembly caching done by the debugger, but not matter what I do (clean project, delete bin folders, restart VS, etc) I can never get the right assembly to load. Has anyone else seen this behavior? Any solutions?

By the way, using Resharper 4.5, and .NET 3.5 on Win XP.

How would one enter special characters into a `Label` in C# (Windows Forms)? 

If you try to write a &quot;&amp;&quot; into a label you&#39;ll get a sort of underscore instead..

So what&#39;s the C# equivalent of &quot;&amp;&quot;? (&quot;\&amp;&quot; obviously doesn&#39;t work).


Enter &quot;&amp;&quot; symbol into a text Label in Windows Forms?

In `WinForms` I am using a `Label` to display different messages like success, failure, etc.

I&#39;d like to center that label in the center form. I want a solution that will keep it centered whether there&#39;s just one word or a whole sentence in the label.


How do I keep a label centered in WinForms?

To get stuck in straight away, a very basic example:

    using System;
    using System.Windows.Forms;
    
    class test
    { 
        static void Main()
        { 
            Console.WriteLine(&quot;test&quot;);
            MessageBox.Show(&quot;test&quot;);
        }
    }

If I compile this with default options (using csc at command line), as expected, it will compile to a console application. Also, because I imported `System.Windows.Forms`, it will also show a message box.

Now, if I use the option `/target:winexe`, which I think is the same as choosing `Windows Application` from within project options, as expected I will only see the Message Box and no console output.

(In fact, the moment it is launched from command line, I can issue the next command before the application has even completed).

So, my question is - I know that you can have &quot;windows&quot;/forms output from a console application, but is there anyway to show the console from a Windows application?
