    Dim val = DirectCast([Enum].Parse(GetType(Gender), &quot;Male&quot;), Gender)

&gt; how can I convert a string &quot;Male&quot; to the Gender enum&#39;s Male value?

The accepted solution returns an Enum object. To return the value you want this solution:

    dim MyGender as string = &quot;Male&quot;
    dim Value as integer
    Value = DirectCast([Enum].Parse(GetType(Gender), MyGender), Integer)

Can also do it this way:

    value = cInt([enum].Parse(GetType(Gender), MyGender))


If you want the parse to be case insensitive, you can use the following:

    [Enum].Parse(Gender, DirectCast(MyGender, String), True)

This will handle `dim MyGender as string = &quot;Male&quot;` or `dim MyGender as string = &quot;male&quot;`

I&#39;m currently working in another country, and my PC has a non-English version of Windows installed. I don&#39;t care about this, but I do care a lot when Visual Studio shows error messages because they are also localized to the same language as Windows.

Sometimes I spend a good time trying to find what it means, which is pretty boring...

Is there any way to configure Windows or Visual Studio to display the messages in English?

I have a large server log file (~750 MB) which I can&#39;t open with either Notepad or Notepad++ (they both say the file is too large).

Can anyone suggest a program (for Windows) that will only read a small part of the file into memory at a time?

Or do I need to write my own app to parse this file?

How can I parse a string in VB.NET to enum value?

Example I have this enum:

    Public Enum Gender
        NotDefined
        Male
        Female
    End Enum

how can I convert a string &quot;Male&quot; to the `Gender` enum&#39;s `Male` value?

I would like to append one DataTable to another DataTable. I see the DataTable class has two methods; &quot;Load(IDataReader)&quot; and &quot;Merge(DataTable)&quot;.  From the documentation, both appear to &#39;merge&#39; the incoming data with the existing DataTable if rows exist. I will be doing the merge in a data access layer.

I could use an `IDataReader` and use the Load method to merge the DataTables. Or I could load a DataSet using the `IDataReader`, get the DataTable from the DataSet, and then use the Merge method to merge the DataTables.

I was wondering if someone could tell me which is the proper method to use?

Alternatively, let me know if you have a different suggestion on how to accomplish this task.

Is it considered an acceptable practice to use Modules instead of Classes with Shared member functions in VB.NET?

I tend to avoid Modules, because they feel like leftover remains from Visual Basic 6.0 and don&#39;t really seem to fit in anymore. On the other hand, there doesn&#39;t seem to be much difference between using a Module and a Class with only Shared members. It&#39;s not that often that I really have much need for either, but sometimes there are situations where they present a simple solution.

I&#39;m curious to hear whether you have any opinion or preferences one way or the other.


Classes vs. Modules in VB.NET

For example:

    BitmapImage bitmap = new BitmapImage();
     
    byte[] buffer = GetHugeByteArray(); // from some external source
    using (MemoryStream stream = new MemoryStream(buffer, false))
    {
        bitmap.BeginInit();
        bitmap.CacheOption = BitmapCacheOption.OnLoad;
        bitmap.StreamSource = stream;
        bitmap.EndInit();
        bitmap.Freeze();
    }

Can you tell me any more about `using`?

**Edit:**

As was discussed in the comments of JaredPar&#39;s post, this question is more concerned with an implementation of `Using` in VS2003.  It was pointed out that `Using` was not introduced until .NET 2.0 (VS2005).  JaredPar posted an equivalent workaround.

Is there anyway, in a program, to detect if a program is being run from inside a remote desktop session or if the program is being run normal in .NET 2.0? What I&#39;m trying to do is, I create a timeclock application which will clock a person in and out and keep track. But this particular person, I suspect, is remoting into their computer at work, from home, and clocking in and out. 

Any ideas how I can solve this issue (and taking away remote desktop access is not an option)? My idea is, if there is a way to detect remote desktop sessions, I will simply implement this into the progam and prevent them from clocking in remotely.

How can I get the number of items defined in an enum?

Total number of items defined in an enum

For people suggesting throwing an exception:  
Throwing an exception doesn&#39;t give me a compile-time error, it gives me a runtime error. I know I can throw an exception, I&#39;d rather die during compilation than during runtime.

First-off, I am using eclipse 3.4.

I have a data model that has a mode property that is an Enum.

    enum Mode {on(...), off(...), standby(...); ...}

I am currently writing a view of this model and I have the code

    ...
    switch(model.getMode()) {
    case on:
       return getOnColor();
    case off:
       return getOffColor();
    case standby:
       return getStandbyColor();
    }
    ...

I am getting an error &quot;This method must return a result of type java.awt.Color&quot; because I have no default case and no return xxx at the end of the function.
**I _want_ a compilation error in the case where someone adds another type to the enum (e.g. shuttingdown) so I don&#39;t want to put a default case that throws an AssertionError, as this will compile with a modified Mode and not be seen as an error until runtime.**

My question is this:  
Why does EclipseBuilder (and javac) not recognize that this switch covers all possibilities (or does it cover them?) and stop warning me about needing a return type. Is there a way I can do what I want without adding methods to Mode?

Failing that, is there an option to warn/error on switch statements that don&#39;t cover all of the Enum&#39;s possible values?

Edit: 
Rob: It is a compile *error*. I just tried compiling it with javac and I get a &quot;missing return statement&quot; error targeting the last } of the method. Eclispe just places the error at the top of the method.

a lot of people have answered the question of how to bind an enum to a combo box in WinForms. Its like this:

    comboBox1.DataSource = Enum.GetValues(typeof(MyEnum));

But that is pretty useless without being able to set the actual value to display.

I have tried:

    comboBox1.SelectedItem = MyEnum.Something; // Does not work. SelectedItem remains null

I have also tried:

    comboBox1.SelectedIndex = Convert.ToInt32(MyEnum.Something); // ArgumentOutOfRangeException, SelectedIndex remains -1

Does anyone have any ideas how to do this?

Binding an enum to a WinForms combo box, and then setting it

I&#39;d like to create a generic method for converting any System.Enum derived type to its corresponding integer value, without casting and preferably without parsing a string.

Eg, what I want is something like this:

    // Trivial example, not actually what I&#39;m doing.
    class Converter
    {
        int ToInteger(System.Enum anEnum)
        {
            (int)anEnum;
        }
    }

But this doesn&#39;t appear to work. Resharper reports that you can not cast expression of type &#39;System.Enum&#39; to type &#39;int&#39;.

Now I&#39;ve come up with this solution but I&#39;d rather have something more efficient.

    class Converter
    {
        int ToInteger(System.Enum anEnum)
        {
            return int.Parse(anEnum.ToString(&quot;d&quot;));
        }
    }

Any suggestions?

How to convert from System.Enum to base integer?

I have a class called `Questions` (plural). In this class there is an enum called `Question` (singular) which looks like this.

    public enum Question
    {
        Role = 2,
        ProjectFunding = 3,
        TotalEmployee = 4,
        NumberOfServers = 5,
        TopBusinessConcern = 6
    }

In the `Questions` class I have a `get(int foo)` function that returns a `Questions` object for that `foo`. Is there an easy way to get the integer value off the enum so I can do something like this `Questions.Get(Question.Role)`?
