在Vista系統之後,微軟為表單程式提供了Aero磨砂的效果,如。那麼用C#如
何來實現這種磨砂效果呢?
代碼:
using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;using System.Reflection;using System.Runtime.InteropServices;//引用DLL申明namespace WindowsFormsApplication1{ public partial class Form1 : Form { //DLL申明 [StructLayout(LayoutKind.Sequential)] public struct MARGINS { public int Left; public int Right; public int Top; public int Bottom; } //DLL申明 [DllImport("dwmapi.dll", PreserveSig = false)] static extern void DwmExtendFrameIntoClientArea(IntPtr hwnd, ref MARGINS margins); //DLL申明 [DllImport("dwmapi.dll", PreserveSig = false)] static extern bool DwmIsCompositionEnabled(); //直接添加代碼 protected override void OnLoad(EventArgs e) { if (DwmIsCompositionEnabled()) { MARGINS margins = new MARGINS(); margins.Right = margins.Left = margins.Top = margins.Bottom = this.Width + this.Height; DwmExtendFrameIntoClientArea(this.Handle, ref margins); } base.OnLoad(e); } //直接添加代碼 protected override void OnPaintBackground(PaintEventArgs e) { base.OnPaintBackground(e); if (DwmIsCompositionEnabled()) { e.Graphics.Clear(Color.Black); } } public Form1() { InitializeComponent(); } }}
這中效果的實現主要是調用了系統的dwmapi.dll。
dwmapi.dll是Microsoft Desktop Window Manager API(桌面視窗管理員DWM 的公用介面)的動態連結程式庫,正常檔案,主要用作案頭效果的api。
DWM 是一種新介面,在除 Windows Vista Home Basic 之外的所有 Windows Vista 版本中均提供 DWM 介面。所以這種效果只能在Vista之後的系統中使用。
