This article mainly introduces "the basic concept of VB.NET notification control". In daily operation, I believe that many people have doubts about the basic concept of VB.NET notification control. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "basic concepts of VB.NET notification control". Next, please follow the editor to study!

The VB.NET notification control consists of two basic classes:

A form (the part that will actually be displayed). A class that contains all the attributes that can be included in the form.

Class contains two timers, one to control the fading animation effect, and the other can be configured to define how long the pop-up window is displayed. Here is a demonstration:

FPopup.Size = Size

FPopup.Opacity = 0

FPopup.Location = _ New

Point (Screen.PrimaryScreen.

WorkingArea.Right_-

FPopup.Size.Width-1

_ Screen.PrimaryScreen.

WorkingArea.Bottom)

FPopup.Show ()

Form finishes drawing in the Paint event. The author uses the following function to get a lighter / darker color than the specified color, but is not sure if there is a better way.

Private Function GetDarkerColor ()

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

To avoid flickering: Me.SetStyle (ControlStyles.

OptimizedDoubleBuffer, True)

Me.SetStyle (ControlStyles.

ResizeRedraw, True)

Me.SetStyle (ControlStyles.

AllPaintingInWmPaint, True)
