A nice little control to help the user notice you're trying to tell him something...

Introduction

This is a simple project, a control that mimics the Microsoft® Outlook® 2003 mail alert.

Features

This control has several features. Among them, you'll find:

Progressive appearance - transparency

MSN Messenger like pop-ups (any size, color, etc.)

Another sample

This control is 100% drawn in the code, there is absolutely no other dependencies than System.Drawing and System.Windows.Forms.

You can include a ContextMenuStrip when clicking on the "down arrow" button.

Using the code

The controls is made of two basic classes:

A form (the part that will actually show up).
A class that contains all the properties that will be includable on forms.

The class contains two timers, one used for the appearing/disappearing animation, the other (configurable) is used to define how much time the popup is shown before it disappears.

This is how the form is actually shown:

fPopup.Size = Size
fPopup.Opacity = 0
fPopup.Location = _
  New Point(Screen.PrimaryScreen.WorkingArea.Right_
   - fPopup.Size.Width - 1, _
   Screen.PrimaryScreen.WorkingArea.Bottom)
fPopup.Show()

The form is does the drawing in the Paint event.

I'm using these functions to obtain a color that is similar but lighter/darker. There might exist another method.

Private Function GetDarkerColor(ByVal Color As Color) As Color
    Dim clNew As Color
    clNew = Drawing.Color.FromArgb(255, DedValueMin0(CInt(Color.R), _
            Parent.GradientPower), DedValueMin0(CInt(Color.G), _
            Parent.GradientPower), DedValueMin0(CInt(Color.B), _
            Parent.GradientPower))
    Return clNew
End Function

And to avoid flickering...

Me.SetStyle(ControlStyles.OptimizedDoubleBuffer, True)
Me.SetStyle(ControlStyles.ResizeRedraw, True)
Me.SetStyle(ControlStyles.AllPaintingInWmPaint, True)
