 - Resource files give you an easy way to localize/internationalize your .net applications by automatically determining which language resx file to use based on the user&#39;s locale.  To add more languages, simply add another translated resource file.

 - Resource files give you a central location to store your strings, files and scripts and refer to them in a strongly-typed manner (so the compile will break if you reference them improperly).

 - Resource files can be compiled into satellite assemblies, making it easy to change up the resources in a production application without having to recompile the whole thing.


As a supplement to the other answers, string resources are for human-readable text, not constants that will be used programmatically. They&#39;re great for error messages, button labels and the like.

Very often, rather than the final string, we store a format string so that variables can be substituted in at the last moment. The nice thing about this method is that, unlike concatenation, it&#39;s not broken when a language has different word order requirements.

Resource files enable you to change the text/graphics your program will display without editting the code of the program itself.  For many reasons, it is often considered ideal to avoid needing to edit your program&#39;s source code in order to make changes that are not part of your application&#39;s logic.

With resx you can have one per language (that is spoken language not programming language) enabling your program / system to be multilingual.

In addition to the answers above, resource files can also provide you an place to store test files for performing Read/Write tests. That way, regardless of how other people&#39;s environment is set up, you can have a place to store logs or other files. 

Keep in mind that what files you do place in resources must be serializable. Check below for more info:

I&#39;m trying to find any information I can on the PastryKit Javascript Framework. It appears to be in use on the iPhone User Guide that is displayed on the iPhone itself in Mobile Safari, but I cannot find any documentation or API. If you want to see it in action, open Safari 4, set your user agent to iPhone 3 (In the Develop menu) and check out [the guide][1].

Overall, it seems to be a way to write an HTML/CSS/Javascript application that acts like a native iPhone app.

When it comes to Javascript, I used the [JS Beautifier][2] on (what I assume to be) the [framework file][3] and it was over 3,400 lines! Beautified, (again what I assume to be) [their implementatio][4]n of it was over 1,200 lines.

On the CSS side, I used [Clean CSS][5] on (again what I assume to be) the [framework CSS][6], and it came out to over 700 lines. [Their implementation][7] was shy of 500.

Does anybody have, or know where to find, any information, documentation, or APIs on PastryKit? Or, can anybody figure out how to implement it?

What are the possible causes of a &quot;java.lang.Error: Unresolved compilation problem&quot;?

Additional information: 

I have seen this after copying a set of updated JAR files from a build on top of the existing JARs and restarting the application. The JARs are built using a Maven build process.

I would expect to see LinkageErrors or ClassNotFound errors if interfaces changed. The above error hints at some lower level problem.

A clean rebuild and redeployment fixed the problem. Could this error indicate a corrupted JAR?

I don&#39;t really care about encoding and stuff, as long as I get back the exact same byte array.

So to sum up: How do I convert a byte array into a string, and then that string back into the same byte array I started with?

How can I safely convert a byte array into a string and back?

I&#39;ve seen both exception messages with and without a period. And I can think of some reasons of why both could be good.

- No dot would give you the freedom to add the period or leave it out if you wanted to. Could be useful if the message was going in some sort of a title bar or something.
- With a dot, you would always know that you had a &quot;complete sentence&quot; and it looks more finished.

Which one do you recommend?

Could also be an issue in localized resource strings. Obviously, you can&#39;t put a period after everything (would look weird with periods after text on buttons and menu items, etc.). But should you then leave the period out from everything to be consistent and add it later where useful? Or would you rather put a period where it seems fit? For example, after all resource strings and exception messages that are sentences, but not after those that are words. But then, how about very short sentences? Like, &quot;Create a new file&quot;, for example. Could maybe leave out periods for strings that were considered actions as well... (Just thinking while I&#39;m typing here...)

Not the most important thing in the world, I know, but small things like this that tend to bug me after a while. I like consistency and to know why I do what I do. Problem is, I&#39;m not sure which one to go for :p

Do you end your exception messages with a period?

Sample console program.

    class Program
    {
        static void Main(string[] args)
        {
            // ... code to build dll ... not written yet ...
            Assembly assembly = Assembly.LoadFile(@&quot;C:\dyn.dll&quot;);
            // don&#39;t know what or how to cast here
            // looking for a better way to do next 3 lines
            IRunnable r = assembly.CreateInstance(&quot;TestRunner&quot;);
            if (r == null) throw new Exception(&quot;broke&quot;);
            r.Run();

        }
    }

I want to dynamically build an assembly (.dll), and then load the assembly, instantiate a class, and call the Run() method of that class. Should I try casting the TestRunner class to something? Not sure how the types in one assembly (dynamic code) would know about my types in my (static assembly / shell app). Is it better to just use a few lines of reflection code to call Run() on just an object? What should that code look like?

How can I do a select in linq to entities to select rows with keys from a list?  Something like this:

    var orderKeys = new int[] { 1, 12, 306, 284, 50047};
    var orders = (from order in context.Orders 
                  where (order.Key in orderKeys) 
                  select order).ToList();
    Assert.AreEqual(orderKeys.Count, orders.Count);

I tried using the *Contains* method as mentioned in some of the answers but it does not work and throws this exception:

*LINQ to Entities does not recognize the method &#39;Boolean Contains[Int32](System.Collections.Generic.IEnumerable`1[System.Int32], Int32)&#39; method, and this method cannot be translated into a store expression.*

I need to remove the focus from several TextBoxes. I tried using:

    textBox1.Focused = false;

Its `ReadOnly` property value is `true`.

I then tried setting the focus on the form, so as to remove it from all the TextBoxes, but this also fails to work:

    this.Focus();

and the function returns `false` when a textbox is selected.

So, how do I remove the focus from a TextBox?

I&#39;ve been fighting with this for a while, and have found that a number of other people struggle with the TableLayoutPanel (.net 2.0 Winforms) as well.

**Problem**

I am attempting to take a &#39;blank&#39; tablelayoutpanel, which has 10 columns defined, then at runtime programmatically add rows of controls (i.e. one control per cell).

One might have thought that it should be as simple as 

    myTableLayoutPanel.Controls.Add(myControl, 0 /* Column Index */, 0 /* Row index */);

But that (for me) doesn&#39;t add the rows. So maybe adding in a row style

    myTableLayoutPanel.RowStyles.Clear();
    myTableLayoutPanel.RowStyles.Add(new RowStyle(SizeType.Absolute, 30F));

But that doesn&#39;t work either. I&#39;ve dug around and found out that the `myTableLayoutPanel.RowCount` usage changes from design time to run time, hence doing `myTableLayoutPanel.RowCount++;` doesn&#39;t actually add another row, not even before/after adding a RowStyle entry for it!

Another related issue I am encountering is that the controls will be added to the display, but they all simply get rendered at point 0,0 of the TableLayoutPanel, additionally they are not even constrained to be within the Cell bounds that they are supposed to be displayed within (i.e. with Dock = DockStyle.Fill they still appear way too large/small).

Does someone have a working example of adding rows &amp; controls at runtime?

Okay, I&#39;ve checked Environment.SpecialFolder, but there&#39;s nothing in there for this.


I want to get the home directory of the current user in C#. (e.g. `c:\documents and settings\user` under XP, `c:\users\user` under Vista, and `/home/user` under Unix.)

I know I can read enviroment variables to find this out, but I want to do this in a cross-platform way.

Is there any way I can do this with .NET (preferably using mscorlib)?

**UPDATE**: Okay, this is the code I ended up using:

    string homePath = (Environment.OSVersion.Platform == PlatformID.Unix || 
                       Environment.OSVersion.Platform == PlatformID.MacOSX)
        ? Environment.GetEnvironmentVariable(&quot;HOME&quot;)
        : Environment.ExpandEnvironmentVariables(&quot;%HOMEDRIVE%%HOMEPATH%&quot;);

I see that the `Finally` in `Try .. Catch` will always execute after any parts of the execution of the try catch block.
 
Is it any different to just skip the `Finally` section and just run it after, outside the try catch block?

Example 1, Try ... Catch ... Finally ... End Try
----------------------------------------

        Try
            &#39;Do something
        Catch ex As Exception
            &#39;Handle exception
        Finally
            &#39;Do cleanup
        End Try

Example 2, Try ... Catch ... End Try ... Do the finally stuff outside
----------------------------------------


        Try
            &#39;Do something
        Catch ex As Exception
            &#39;Handle exception
        End Try
        &#39;Do cleanup


Why use Finally in Try ... Catch

What&#39;s the difference between **or** and **OrElse**?

    if temp is dbnull.value or temp = 0

produces the error:
&gt; Operator &#39;=&#39; is not defined for type &#39;DBNull&#39; and type &#39;Integer&#39;.

while this one works like a charm!?

    if temp is dbnull.value OrElse temp = 0

I&#39;m trying to match on some inconsistently formatted HTML and need to strip out some double quotes.

Current:

    &lt;input type=&quot;hidden&quot;&gt;

The Goal:

    &lt;input type=hidden&gt;


This is wrong because I&#39;m not escaping it properly:

&gt; s = s.Replace(&quot;&quot;&quot;,&quot;&quot;);

This is wrong because there is not blank character character (to my knowledge):

    s = s.Replace(&#39;&quot;&#39;, &#39;&#39;);

What is syntax / escape character combination for replacing double quotes with an empty string?


Strip double quotes from a string in .NET

I recently learned of the IIF(A,B,C) function. I&#39;m a long time VB/VB.NET Coder who recently spent a lot of time coming up to speed in SQL coding.

One (obvious) common thing to do in SQL is something like the following:

    select (case where @var = 0 then MyTable.Val1 else MyTable.Val2 end) from MyTable

IIF(A,B,C) will allow me to do this in VB.NET... all on one line. 

However, I have read that both B and C are evaluated no matter what A evaluates to. 

I can think of some obvious situations where this is a bad thing such as:

    Dim X as integer = IIF(SomeBoolean = true, ExpensiveFunction1(), ExpensiveFunction2())

As I will be including this in my repertoire, are there any more subtle situations where I may get myself into trouble using IIF?

It&#39;s a pretty big departure in some situations from using the old fashioned:

    Dim X as integer
    if SomeBoolean = true then
      X = ExpensiveFunction1()
    else
      X = ExpensiveFunction2()
    end if

I&#39;m hoping to save myself some annoying performance issues and/or bugs in the future. 

# Update 2016

For the past few years, a new VB.NET feature exists which eliminates the need to use the IIF() function.

    if(Something = true, ExecuteA(), ExecuteB())

Only ExecuteA() OR ExecuteB() are executed. Finally, inline IF with shortcircuiting. 

So, if you are using later versions of VB.NET (as of 2016), use this instead if you can. 

VB.NET - IIF(,,) - Both &quot;sides&quot; are evaluated. What situations should I watch out for?

In my webproject I&#39;m using 4 resources files in my `App_GlobalResources` folder. One of them (`lang.resx`) has been created before my arrival on the project. It has the correct namespace (`WebApplication.App_GlobalResources`) and access modifier : `public`.

On the other hand, the three others Resource files that I just created have a different namespace (`Resources`) and `internal` access modifier, and I can&#39;t change it on the Resource File Form from Visual Studio because it&#39;s disabled. If I try to change it directly in the designer.cs file, the modifications are cancelled on the next save of the file.

It&#39;s not a critical bug but it can be misleading for the others developers on the project to find different namespaces and access modifiers for the resources files they will use.

Changing Resource files (resx) namespace and access modifier

I have a localized application, and I am wondering if it is possible to have the `DisplayName` for a certain model property set from a Resource.

I&#39;d like to do something like this:

    public class MyModel {
      [Required]
      [DisplayName(Resources.Resources.labelForName)]
      public string name{ get; set; }
    }

But I can&#39;t to it, as the compiler says: &quot;An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type&quot; :(

Are there any workarounds? I am outputting labels manually, but I need these for the validator output!

DisplayName attribute from Resources?

Is it possible to add some value from resource file right into the XAML markup? Or for localization we always have to make something like this in *.cs file:

    txtMessage.Text = Messages.WarningUserMessage;

Where `Messages` is resource, and `txtMessage` is TextBlock.
