1.自定义窗体
项目中都保持一个窗体风格，比如窗体标题栏，最小化最大化按钮。建立一个form窗体，修改后，编译生成dll，添加引用此dll,继承此dll窗体。
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using MyFormDLL; namespace WindowsFormsApplication2 { public partial class Form1 : FrmBaseWindow { public Form1() { InitializeComponent(); } private void panelTitle_Paint(object sender, PaintEventArgs e) { } private void Form1_Load(object sender, EventArgs e) { CanResize = true; MyWindowTitle = "999988888"; } } }
自定义的窗体，FormBorderStyle 设置成None,放置Panel，在Panel放置最大化最小化关闭按钮
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace MyFormDLL { public partial class FrmBaseWindow : Form { private string _myWindowTitle; [DefaultValue(typeof(string), "TTC 称重管理平台")] public string MyWindowTitle { get { return _myWindowTitle; } set { _myWindowTitle = value; lblTitle.Text = _myWindowTitle; } } //是否允许窗体改变大小 public bool CanResize{get;set;} public FrmBaseWindow() { InitializeComponent(); } private void FrmBaseWindow_Load(object sender, EventArgs e) { } private void btnMaxSize_Click(object sender, EventArgs e) { if (this.WindowState == FormWindowState.Maximized) { this.WindowState = FormWindowState.Normal; } else { this.WindowState = FormWindowState.Maximized; } } private void btnMinSize_Click(object sender, EventArgs e) { this.WindowState = FormWindowState.Minimized; } private void btnClose_Click(object sender, EventArgs e) { this.Close(); } protected override void WndProc(ref Message m) { switch (m.Msg) { //case Win32.WM_ERASEBKGND: // m.Result = IntPtr.Zero; // break; case Win32.WM_NCHITTEST: WmNcHitTest(ref m); break; default: base.WndProc(ref m); break; } } //调整窗体大小 private void WmNcHitTest(ref Message m) { int wparam = m.LParam.ToInt32(); Point mouseLocation = new Point(LOWORD(wparam), HIWORD(wparam)); mouseLocation = PointToClient(mouseLocation); if (WindowState != FormWindowState.Maximized) { if (CanResize == true) { if (mouseLocation.X < 5 && mouseLocation.Y < 5) { m.Result = new IntPtr(Win32.HTTOPLEFT); return; } if (mouseLocation.X > Width - 5 && mouseLocation.Y < 5) { m.Result = new IntPtr(Win32.HTTOPRIGHT); return; } if (mouseLocation.X < 5 && mouseLocation.Y > Height - 5) { m.Result = new IntPtr(Win32.HTBOTTOMLEFT); return; } if (mouseLocation.X > Width - 5 && mouseLocation.Y > Height - 5) { m.Result = new IntPtr(Win32.HTBOTTOMRIGHT); return; } if (mouseLocation.Y < 3) { m.Result = new IntPtr(Win32.HTTOP); return; } if (mouseLocation.Y > Height - 3) { m.Result = new IntPtr(Win32.HTBOTTOM); return; } if (mouseLocation.X < 3) { m.Result = new IntPtr(Win32.HTLEFT); return; } if (mouseLocation.X > Width - 3) { m.Result = new IntPtr(Win32.HTRIGHT); return; } } } m.Result = new IntPtr(Win32.HTCAPTION); //标题栏随最大化移动 //panelTitle.Width = mouseLocation.X - 2; } /// <summary> /// 取低位 X 坐标 /// </summary> public static int LOWORD(int value) { return value & 0xFFFF; } /// <summary> /// 取高位 Y 坐标 /// </summary> public static int HIWORD(int value) { return value >> 16; } protected override void OnMouseMove(MouseEventArgs e) { base.OnMouseMove(e); } protected override void OnMouseDown(MouseEventArgs e) { base.OnMouseDown(e); if (e.Button == MouseButtons.Left) { Win32.ReleaseCapture(); Win32.SendMessage(this.Handle, Win32.WM_NCLBUTTONDOWN, Win32.HTCAPTION, 0); } } private void panelTitle_MouseDown(object sender, MouseEventArgs e) { base.OnMouseDown(e); if (e.Button == MouseButtons.Left) { Win32.ReleaseCapture(); Win32.SendMessage(this.Handle, Win32.WM_NCLBUTTONDOWN, Win32.HTCAPTION, 0); } } private void FrmWindow_SizeChanged(object sender, EventArgs e) { // this.lblTitle.Location = new System.Drawing.Point(50, 2); //标题栏随最大化移动 panelTitle.Width = this.Width; //移动控制按钮 this.btnMinSize.Location = new System.Drawing.Point(this.Width - 140, 2); this.btnMaxSize.Location = new System.Drawing.Point(this.Width - 90, 2); this.btnClose.Location = new System.Drawing.Point(this.Width - 50, 2); } } }
