トリックは、HwndSourceを取得し、そのAddHook()メソッドを呼び出すことです。これは動作します:
Imports System.Windows.Interop
Class Window1
Protected Overrides Sub OnSourceInitialized(ByVal e As System.EventArgs)
MyBase.OnSourceInitialized(e)
DirectCast(PresentationSource.FromVisual(Me), HwndSource).AddHook(AddressOf WndProc)
End Sub
Private Const WM_SYSCOMMAND As Integer = &H112
Private Const SC_MAXIMIZE As Integer = &HF030
Private Function WndProc(ByVal hWnd As IntPtr, ByVal msg As Integer, ByVal wp As IntPtr, ByVal lp As IntPtr, ByRef handled As Boolean) As IntPtr
If msg = WM_SYSCOMMAND AndAlso wp.ToInt32() = SC_MAXIMIZE Then
Me.ResizeMode = ResizeMode.NoResize
Me.WindowStyle = WindowStyle.None
Me.WindowState = WindowState.Maximized
handled = True
End If
End Function
End Class
のWinformsフォームで同じコード:
Public Class Form1
Private Const WM_SYSCOMMAND As Integer = &H112
Private Const SC_MAXIMIZE As Integer = &HF030
Protected Overrides Sub WndProc(ByRef m As Message)
If m.Msg = WM_SYSCOMMAND AndAlso m.WParam.ToInt32() = SC_MAXIMIZE Then
Me.FormBorderStyle = FormBorderStyle.None
Me.WindowState = FormWindowState.Maximized
Return
End If
MyBase.WndProc(m)
End Sub
Protected Overrides Function ProcessCmdKey(ByRef msg As Message, ByVal keyData As Keys) As Boolean
'' Restore window when the user presses Escape
If Me.WindowState = FormWindowState.Maximized AndAlso keyData = Keys.Escape Then
Me.FormBorderStyle = Windows.Forms.FormBorderStyle.Sizable
Me.WindowState = FormWindowState.Normal
End If
Return MyBase.ProcessCmdKey(msg, keyData)
End Function
End Class
ありがとうございました。あなたは、私がタスクバーを隠したり隠したりするために必要なものの例を教えてもらえますか? – giodamelio
試しましたか?タスクバーを非表示にする必要はなく、境界線のないウィンドウは重複することができます。 –
それは私にエラーのロードを与えます。 '' OnSourceInitialized 'は' System.Windows.Forms.Form''のメンバーではありません – giodamelio
