Xin chào các bạn, bài viết hôm nay mình tiếp tục hướng dẫn các bạn tạo hiệu ứng Blur Effect Acrylic, Mica and Tabbed của Windows 11 trên Winform bằng ngồn ngữ VB.NET

[VB.NET] How to Blur Effect Acrylic, Mica, Tabbed Windows 11

Giao diện demo ứng dụng:

AcrylicBlurWindows11_web

Ở màn hình này, các bạn có thể chọn giao diện Theme Dark/Light ở nút button.

Video demo ứng dụng Blur Effect VB.NET:

Đầu tiên các bạn tạo 1 class Pinvoke.vb:

Imports System.Runtime.InteropServices

Public Class PInvoke
    Public Class ParameterTypes
        <Flags>
        Public Enum DWMWINDOWATTRIBUTE
            DWMWA_USE_IMMERSIVE_DARK_MODE = 20
            DWMWA_SYSTEMBACKDROP_TYPE = 38
        End Enum

        <StructLayout(LayoutKind.Sequential)>
        Public Structure MARGINS
            Public cxLeftWidth As Integer
            Public cxRightWidth As Integer
            Public cyTopHeight As Integer
            Public cyBottomHeight As Integer
        End Structure
    End Class

    Public Class Methods
        <DllImport("DwmApi.dll")>
        Public Shared Function DwmExtendFrameIntoClientArea(ByVal hwnd As IntPtr, ByRef pMarInset As ParameterTypes.MARGINS) As Integer
        End Function

        <DllImport("dwmapi.dll")>
        Public Shared Function DwmSetWindowAttribute(ByVal hwnd As IntPtr, ByVal dwAttribute As ParameterTypes.DWMWINDOWATTRIBUTE, ByRef pvAttribute As Integer, ByVal cbAttribute As Integer) As Integer

        End Function

        Public Shared Function ExtendFrame(ByVal hwnd As IntPtr, ByVal margins As ParameterTypes.MARGINS) As Integer
            Return DwmExtendFrameIntoClientArea(hwnd, margins)
        End Function

        Public Shared Function SetWindowAttribute(ByVal hwnd As IntPtr, ByVal attribute As ParameterTypes.DWMWINDOWATTRIBUTE, ByVal parameter As Integer) As Integer
            Return DwmSetWindowAttribute(hwnd, attribute, parameter, Marshal.SizeOf(Of Integer)())
        End Function
    End Class
End Class

Và tiếp theo là source code cho Form1.vb

Imports System.Net
Imports System.Windows.Interop
Imports AcrylicBlurWindows11.PInvoke.ParameterTypes
Imports AcrylicBlurWindows11.PInvoke.Methods

Public Class Form1
    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Dim bounds As MARGINS = New MARGINS
        Dim hwnd As IntPtr = Handle
        With bounds
            .cxLeftWidth = 0
            .cxRightWidth = 0
            .cyTopHeight = Me.Height - 105 'Screen.PrimaryScreen.Bounds.Height - 60
            .cyBottomHeight = 0
        End With


        Dim result As Integer = DwmExtendFrameIntoClientArea(hwnd, bounds)
        Me.BackColor = Color.Black

        Dim Panel As New Panel
        With Panel
            .Size = New Size(Me.Width, Me.Height - 60)
            .Location = New Point(0, 0)
            .Anchor = AnchorStyles.Left Or AnchorStyles.Right Or AnchorStyles.Top Or AnchorStyles.Bottom
            .BackColor = Color.FromKnownColor(KnownColor.Control)
        End With
        'Panel.Dock = DockStyle.Fill
        ' Me.Controls.Add(Panel)
    End Sub

    Private Sub rdoArcylic_CheckedChanged(sender As Object, e As EventArgs) Handles rdoArcylic.CheckedChanged
        If rdoArcylic.Checked Then
            SetWindowAttribute(Me.Handle, DWMWINDOWATTRIBUTE.DWMWA_SYSTEMBACKDROP_TYPE, 3)
        End If
    End Sub

    Private Sub rdoMica_CheckedChanged(sender As Object, e As EventArgs) Handles rdoMica.CheckedChanged
        If rdoMica.Checked Then
            SetWindowAttribute(Me.Handle, DWMWINDOWATTRIBUTE.DWMWA_SYSTEMBACKDROP_TYPE, 2)
        End If
    End Sub

    Private Sub rdoTabbed_CheckedChanged(sender As Object, e As EventArgs) Handles rdoTabbed.CheckedChanged
        If rdoTabbed.Checked Then
            SetWindowAttribute(Me.Handle, DWMWINDOWATTRIBUTE.DWMWA_SYSTEMBACKDROP_TYPE, 4)
        End If
    End Sub

    Private Sub rdoNone_CheckedChanged(sender As Object, e As EventArgs) Handles rdoNone.CheckedChanged
        If rdoNone.Checked Then
            SetWindowAttribute(Me.Handle, DWMWINDOWATTRIBUTE.DWMWA_SYSTEMBACKDROP_TYPE, 1)
        End If
    End Sub

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        If Button1.Tag.ToString() = "0" Then
            SetWindowAttribute(
            Me.Handle,
             DWMWINDOWATTRIBUTE.DWMWA_USE_IMMERSIVE_DARK_MODE,
             1)
            Button1.Tag = "1"
            Button1.Text = "Light"
        Else
            SetWindowAttribute(
           Me.Handle,
            DWMWINDOWATTRIBUTE.DWMWA_USE_IMMERSIVE_DARK_MODE,
            0)
            Button1.Tag = "0"
            Button1.Text = "Dark"
        End If

    End Sub
End Class
