I used Spy++ to figure this out a while ago and discovered that it&#39;s just a standard Win32 Static control -- the equivalent of the WinForms Label.  Steps for getting the same effect:

 1. Add a Label control to your form.
 2. Set Label Text to empty.
 3. Set BorderStyle to Fixed3D.
 4. Set AutoSize to false.
 5. Set Height to 2 (most easily accomplished by typing 2 into the Size/Height field under Label Properties).


I use the following function to calculate log base 2 for integers:

    public static int log2(int n){
        if(n &lt;= 0) throw new IllegalArgumentException();
        return 31 - Integer.numberOfLeadingZeros(n);
    }

Does it have optimal performance?

Does someone know ready J2SE API function for that purpose?

**UPD1** *Surprisingly for me, float point arithmetics appears to be faster than integer arithmetics.*

**UPD2** *Due to comments I will conduct more detailed investigation.*

**UPD3** *My integer arithmetic function is 10 times faster than Math.log(n)/Math.log(2).*

Sometimes I try a customization/command in my vimrc. Everything seens to be correct, but it just doesn&#39;t work.

It&#39;s difficult to know what&#39;s happening when vim starts, and know which command failed or not, so it&#39;s really difficult to debug what can be causing a problem in my vimrc. It&#39;s a trial-error approach, which is time consuming and really a PITA. For example, I&#39;m having problems [with snipmate plugin in some files][1] and just don&#39;t have a clue on how to discover the problem.

Is there a &quot;runtime log&quot; when vim starts, telling which commands it executed, which ones failed and such? This would help me a lot.

In the standard windows installer there is a divider between the control buttons on the bottom and the main part of the form. Does anyone know how this would be done in winforms/.net? I&#39;ve tried fiddling around with the border settings on Panel controls etc, but haven&#39;t been able to get the same result...

How do I read an embedded resource (text file) using `StreamReader` and return it as a string?  My current script uses a Windows form and textbox that allows the user to find and replace text in a text file that is not embedded. 

    private void button1_Click(object sender, EventArgs e)
    {
        StringCollection strValuesToSearch = new StringCollection();
        strValuesToSearch.Add(&quot;Apple&quot;);
        string stringToReplace;
        stringToReplace = textBox1.Text;

        StreamReader FileReader = new StreamReader(@&quot;C:\MyFile.txt&quot;);
        string FileContents;
        FileContents = FileReader.ReadToEnd();
        FileReader.Close();
        foreach (string s in strValuesToSearch)
        {
            if (FileContents.Contains(s))
                FileContents = FileContents.Replace(s, stringToReplace);
        }
        StreamWriter FileWriter = new StreamWriter(@&quot;MyFile.txt&quot;);
        FileWriter.Write(FileContents);
        FileWriter.Close();
    }

which one is better? at a glance optional parameter seems better (less code, less XML documentation, etc), but why do most MSDN library classes use overloading instead of optional parameters?

Is there any special thing you have to take note when you choose to use optional parameter (or overloading)?

I&#39;m a little fuzzy on what the difference between a &quot;group&quot; and a &quot;capture&quot; are when it comes to .NET&#39;s regular expression language.  Consider the following C# code:

    MatchCollection matches = Regex.Matches(&quot;{Q}&quot;, @&quot;^\{([A-Z])\}$&quot;);

I expect this to result in a single capture for the letter &#39;Q&#39;, but if I print the properties of the returned `MatchCollection`, I see:

    matches.Count: 1
    matches[0].Value: {Q}
    matches[0].Captures.Count: 1
    matches[0].Captures[0].Value: {Q}
    matches[0].Groups.Count: 2
    matches[0].Groups[0].Value: {Q}
    matches[0].Groups[0].Captures.Count: 1
    matches[0].Groups[0].Captures[0].Value: {Q}
    matches[0].Groups[1].Value: Q
    matches[0].Groups[1].Captures.Count: 1
    matches[0].Groups[1].Captures[0].Value: Q

What exactly is going on here?  I understand that there&#39;s also a capture for the entire match, but how do the groups come in?  And why doesn&#39;t `matches[0].Captures` include the capture for the letter &#39;Q&#39;?

I need to get all controls on a form that are of type x. I&#39;m pretty sure I saw that code once in the past that used something like this:

    dim ctrls() as Control
    ctrls = Me.Controls(GetType(TextBox))

I know I can iterate over all controls getting children using a recursive function, but 
is there something easier or more straightforward, maybe like the following?

    Dim Ctrls = From ctrl In Me.Controls Where ctrl.GetType Is Textbox

Does the task parallel library have anything that would be considered a replacement or improvement over the BackgroundWorker class? 

I have a WinForms application with a wizard-style UI, and it does some long-running tasks. I want to be able to have a responsive UI with the standard progress bar and ability to cancel the operation. I&#39;ve done this before with BackgroundWorker, but I&#39;m wondering if there are some TPL patterns that can be used instead?
