• 关于c# winForm窗体最大化的设置


    http://blog.csdn.net/cnkivm/archive/2010/05/30/5635166.aspx

    private void btnFormMax_Click(object sender, EventArgs e)
    {
         if (this.WindowState == FormWindowState.Maximized)
         {
       this.WindowState = FormWindowState.Normal;
         }
    else
         {
       this.WindowState = FormWindowState.Maximized;
         }
    }
    此时this.FormBorderStyle. 默认为 Sizable

    2. 窗体最大化时 会全屏 及遮盖任务栏
    private void btnFormMax_Click(object sender, EventArgs e)
    {
          if (this.WindowState == FormWindowState.Maximized)
          {       
             this.WindowState = FormWindowState.Normal;
          }
          else
          {
             this.FormBorderStyle. = FormBorderStyle.None;
             this.WindowState = FormWindowState.Maximized;
          }
       }
    此时this.FormBorderStyle. 为 None 不会显示窗体标题栏等相关

    3. 窗体最大化时 非全屏 不会遮盖任务栏
    private void btnFormMax_Click(object sender, EventArgs e)
    {
          if (this.WindowState == FormWindowState.Maximized)
          {       
             this.WindowState = FormWindowState.Normal;
          }
          else
          {
             this.FormBorderStyle. = FormBorderStyle.None;
             this.MaximumSize = new Size(Screen.PrimaryScreen.WorkingArea.Width, Screen.PrimaryScreen.WorkingArea.Height);
             this.WindowState = FormWindowState.Maximized;
          }
       }

    此时this.FormBorderStyle. 为 None 不会显示窗体标题栏等相关

    using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Drawing;
    using System.Text;
    using System.Windows.Forms;
    namespace WindowsApplication1
    {
    public partial class FormRegion : Form.
    {
    private const long WM_GETMINMAXINFO = 0x24;
    public struct POINTAPI
    {
    public int x;
    public int y;
    }
    public struct MINMAXINFO
    {
    public POINTAPI ptReserved;
    public POINTAPI ptMaxSize;
    public POINTAPI ptMaxPosition;
    public POINTAPI ptMinTrackSize;
    public POINTAPI ptMaxTrackSize;
    }
    public FormRegion()
    {
    InitializeComponent();
    this.MaximumSize = new Size(Screen.PrimaryScreen.WorkingArea.Width, Screen.PrimaryScreen.WorkingArea.Height);
    }
    protected override void WndProc(ref System.Windows.Forms.Message m)
    {
    base.WndProc(ref m);
    if (m.Msg == WM_GETMINMAXINFO)
    {
    MINMAXINFO mmi = (MINMAXINFO)m.GetLParam(typeof(MINMAXINFO));
    mmi.ptMinTrackSize.x = this.MinimumSize.Width;
    mmi.ptMinTrackSize.y = this.MinimumSize.Height;
    if (this.MaximumSize.Width != 0 || this.MaximumSize.Height != 0)
    {
    mmi.ptMaxTrackSize.x = this.MaximumSize.Width;
    mmi.ptMaxTrackSize.y = this.MaximumSize.Height;
    }
    mmi.ptMaxPosition.x = 1;
    mmi.ptMaxPosition.y = 1;
    System.Runtime.InteropServices.Marshal.StructureToPtr(mmi, m.LParam, true);
    }
    }
    }
    }  

    MessageBox.Show("当前窗体标题栏高度"+(this.Height - this.ClientRectangle.Height).ToString());//获得当前窗体标题栏高度获取表示控件的工作区的矩形
    MessageBox.Show(SystemInformation.PrimaryMonitorSize.ToString()); //获取主显示器屏幕的尺寸(像素获取主显示器当前当前视频模式的尺寸(以象素为单位菜单栏高度"+SystemInformation.MenuHeight.ToString()); //获取标准菜单栏的高度标题栏高度"+SystemInformation.CaptionHeight.ToString()); //获取标准标题栏的高度获取一个菜单行的高度(以象素为单位获取窗口的标准标题栏区域的高度(以象素为单位)
