If you are using IntPtr as handles in C# code and wish to avoid handle leaks you may use :
IntPtr handle = some handle;
Marshal.Release(handle);
Google search didn't give me correct answer instantly so I added it here :)

height and width of text with specific font
When you draw a string on a C# form if you want to figure out how many pixel wide and high the text will be use:
TextRenderer Class
To measure the size you may use
TextRenderer.MeasureText :
It returns back System.Drawing.Size which has height and width of the text you wanted.
To draw text you may use:
private void RenderText1(PaintEventArgs e)
{
TextRenderer.DrawText(e.Graphics, "Regular Text", this.Font,
new Point(10, 10), SystemColors.ControlText);
}

Disable right click pop up on textbox in C# winform
It took me almost 3 hours to google the correct way to fix this one...
There are 2 ways of disabling right click on textbox in a C# winform.
1. create a new context menu and add it to the text box control :
TextBox textbox1 = new TextBox();
ContextMenu cm = new ContextMenu();
textbox1.controls.add(cm);
and you are done.
2. Just do
textbox1.ShortcutsEnabled = false;
second one is short and sweet....
