VB net, Draw Text On Glass Window

Text On Glass Window

When you make a glasses window, and you drop a label to the form designer, you will see that the label is not good. to fix this problem, you can use this way (sample code):

Imports System.Runtime.InteropServices

Imports System.Drawing.Drawing2D

Public Class Form1

    Private Sub Form1_Paint() Handles Me.Paint

        Dim g As Graphics = Me.CreateGraphics

        Dim tx As New GraphicsPath

        'Set black to get nice transparent

        Me.BackColor = Color.Black

        'Set this form transparent

        DwmExtendFrameIntoClientArea(Me.Handle, New MARGINS(-1, -1, -1, -1))

        'begin draw text

        tx.AddString("Klampok Child", New FontFamily("Tahoma"), FontStyle.Regular, 30,

                     New Point(12, 12), StringFormat.GenericDefault)

        ' Set Smoothing Mode to get smooth text

        g.SmoothingMode = SmoothingMode.AntiAlias

        'Fill form with text and color (brush)

        g.FillPath(New SolidBrush(Color.Black), tx)

    End Sub

    Private Sub Form1_ResizeEnd() Handles Me.ResizeEnd

        ' When form resize, re-draw the form and show it smooth again

        Me.Refresh()

    End Sub

    ' DwmApi To Call Glasses Window

    <StructLayout(LayoutKind.Sequential)> _

    Public Structure MARGINS

        Public LeftWidth As Integer

        Public RightWidth As Integer

        Public TopHeight As Integer

        Public Buttomheight As Integer

        Public Sub New(ByVal left As Integer, ByVal right As Integer, ByVal top As Integer, ByVal bottom As Integer)

            LeftWidth = left

            RightWidth = right

            TopHeight = top

            Buttomheight = bottom

        End Sub

    End Structure

    <DllImport("dwmapi.dll")> _

    Shared Sub DwmExtendFrameIntoClientArea(ByVal hwnd As IntPtr, ByRef mrg As MARGINS)

    End Sub

End Class
