C# – How to get a TabControl to use the full width of its parent

.netc++tabcontrolwinforms

The standard System.Windows.Forms.TabControl component draws a border around the TabPages it contains. If you set its Dock to Fill, these borders run up to the edge of the parent control, but they're still there, taking up screen space.

In Visual Studio, if you dock two windows in the same place, you get a TabControl-like set of tabs along the bottom, but no borders along the sides.

Is it possible to get a TabControl to display its TabPages in this manner, with no wasted screen space at the sides? If possible, I'd like to avoid solutions that involve painting the control myself.

Best Solution

Remove the height and width attributes from TabControl
Set horizontal and vertical alignment to stretch

e.g. won't stretch;

<TabControl Height="373" Width="609" HorizontalAlignment="Stretch" Name="tabControl1" VerticalAlignment="Stretch"  VerticalContentAlignment="Stretch" HorizontalContentAlignment="Stretch">

e.g. will stretch;

<TabControl HorizontalAlignment="Stretch" Name="tabControl1" VerticalAlignment="Stretch"  VerticalContentAlignment="Stretch" HorizontalContentAlignment="Stretch">

C# – How to get the path of the assembly the code is in

I've defined the following property as we use this often in unit testing.

public static string AssemblyDirectory
{
    get
    {
        string codeBase = Assembly.GetExecutingAssembly().CodeBase;
        UriBuilder uri = new UriBuilder(codeBase);
        string path = Uri.UnescapeDataString(uri.Path);
        return Path.GetDirectoryName(path);
    }
}

The Assembly.Location property sometimes gives you some funny results when using NUnit (where assemblies run from a temporary folder), so I prefer to use CodeBase which gives you the path in URI format, then UriBuild.UnescapeDataString removes the File:// at the beginning, and GetDirectoryName changes it to the normal windows format.

C# – How to use reflection to call a generic method

You need to use reflection to get the method to start with, then "construct" it by supplying type arguments with MakeGenericMethod:

MethodInfo method = typeof(Sample).GetMethod(nameof(Sample.GenericMethod));
MethodInfo generic = method.MakeGenericMethod(myType);
generic.Invoke(this, null);

For a static method, pass null as the first argument to Invoke. That's nothing to do with generic methods - it's just normal reflection.

As noted, a lot of this is simpler as of C# 4 using dynamic - if you can use type inference, of course. It doesn't help in cases where type inference isn't available, such as the exact example in the question.
