devexpress带计时器的等待窗口

在执行一个时间较长的操作时，往往需要设计一个等待窗口，网上找了很多，都没有计时功能，今天自己写一个。

运用到的技术有：devexpress的SplashScreenManager，线程调用。

直接上效果图！！！！！！

接下来是设计思路：

1.设计等待窗口 

等待窗口设计器代码：

namespace IMS_TOOLS.UI.UserForm
{
    partial class WaitForm1
    {
        /// <summary>
        /// Required designer variable.
        /// </summary>
        private System.ComponentModel.IContainer components = null;
 
        /// <summary>
        /// Clean up any resources being used.
        /// </summary>
        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }
 
        #region Windows Form Designer generated code
 
        /// <summary>
        /// Required method for Designer support - do not modify
        /// the contents of this method with the code editor.
        /// </summary>
        private void InitializeComponent()
        {
            this.progressPanel1 = new DevExpress.XtraWaitForm.ProgressPanel();
            this.tableLayoutPanel1 = new System.Windows.Forms.TableLayoutPanel();
            this.labelControl1 = new DevExpress.XtraEditors.LabelControl();
            this.tableLayoutPanel1.SuspendLayout();
            this.SuspendLayout();
            // 
            // progressPanel1
            // 
            this.progressPanel1.Appearance.BackColor = System.Drawing.Color.Transparent;
            this.progressPanel1.Appearance.Options.UseBackColor = true;
            this.progressPanel1.AppearanceCaption.Font = new System.Drawing.Font("Microsoft Sans Serif", 12F);
            this.progressPanel1.AppearanceCaption.Options.UseFont = true;
            this.progressPanel1.AppearanceDescription.Font = new System.Drawing.Font("Microsoft Sans Serif", 8.25F);
            this.progressPanel1.AppearanceDescription.Options.UseFont = true;
            this.progressPanel1.Caption = "请稍后";
            this.progressPanel1.Description = "正在加载...";
            this.progressPanel1.ImageHorzOffset = 20;
            this.progressPanel1.Location = new System.Drawing.Point(0, 16);
            this.progressPanel1.Margin = new System.Windows.Forms.Padding(0, 3, 0, 3);
            this.progressPanel1.Name = "progressPanel1";
            this.progressPanel1.Size = new System.Drawing.Size(246, 35);
            this.progressPanel1.TabIndex = 0;
            this.progressPanel1.Text = "progressPanel1";
            // 
            // tableLayoutPanel1
            // 
            this.tableLayoutPanel1.AutoSize = true;
            this.tableLayoutPanel1.AutoSizeMode = System.Windows.Forms.AutoSizeMode.GrowAndShrink;
            this.tableLayoutPanel1.BackColor = System.Drawing.Color.Transparent;
            this.tableLayoutPanel1.ColumnCount = 1;
            this.tableLayoutPanel1.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent, 100F));
            this.tableLayoutPanel1.Controls.Add(this.progressPanel1, 0, 0);
            this.tableLayoutPanel1.Dock = System.Windows.Forms.DockStyle.Fill;
            this.tableLayoutPanel1.Location = new System.Drawing.Point(0, 0);
            this.tableLayoutPanel1.Name = "tableLayoutPanel1";
            this.tableLayoutPanel1.Padding = new System.Windows.Forms.Padding(0, 13, 0, 13);
            this.tableLayoutPanel1.RowCount = 1;
            this.tableLayoutPanel1.RowStyles.Add(new System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Percent, 100F));
            this.tableLayoutPanel1.Size = new System.Drawing.Size(246, 67);
            this.tableLayoutPanel1.TabIndex = 1;
            // 
            // labelControl1
            // 
            this.labelControl1.Location = new System.Drawing.Point(207, 36);
            this.labelControl1.Name = "labelControl1";
            this.labelControl1.Size = new System.Drawing.Size(19, 14);
            this.labelControl1.TabIndex = 2;
            this.labelControl1.Text = "0秒";
            // 
            // WaitForm1
            // 
            this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);
            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
            this.AutoSize = true;
            this.AutoSizeMode = System.Windows.Forms.AutoSizeMode.GrowAndShrink;
            this.ClientSize = new System.Drawing.Size(246, 67);
            this.Controls.Add(this.labelControl1);
            this.Controls.Add(this.tableLayoutPanel1);
            this.DoubleBuffered = true;
            this.Name = "WaitForm1";
            this.StartPosition = System.Windows.Forms.FormStartPosition.Manual;
            this.Text = "Form1";
            this.FormClosed += new System.Windows.Forms.FormClosedEventHandler(this.WaitForm1_FormClosed);
            this.Load += new System.EventHandler(this.WaitForm1_Load);
            this.tableLayoutPanel1.ResumeLayout(false);
            this.ResumeLayout(false);
            this.PerformLayout();
 
        }
 
        #endregion
 
        private DevExpress.XtraWaitForm.ProgressPanel progressPanel1;
        private System.Windows.Forms.TableLayoutPanel tableLayoutPanel1;
        private DevExpress.XtraEditors.LabelControl labelControl1;
    }
}

 等待窗口代码：

using System;
using System.Collections.Generic;
using System.Windows.Forms;
using DevExpress.XtraWaitForm;
using System.Threading;
 
namespace IMS_TOOLS.UI.UserForm
{
    public partial class WaitForm1 : WaitForm
    {
        // 启动新线程用于计时
        System.Threading.Timer myTimer;
        long TimeCount;
 
        delegate void SetValue();
        
        // 线程执行计时任务
        private void TimerUp(object state)
        {
            if (this.IsHandleCreated)
            {
                this.Invoke(new SetValue(ShowTime));
                TimeCount++;
            }
        }
 
        public void ShowTime()
        {
            TimeSpan t = new TimeSpan(0, 0, (int)TimeCount);
            labelControl1.Text = t.TotalSeconds + "秒";
        }
 
        public WaitForm1()
        {
            InitializeComponent();
            progressPanel1.AutoHeight = true;
        }
 
        private void WaitForm1_Load(object sender, EventArgs e)
        {
            myTimer = new System.Threading.Timer(new TimerCallback(TimerUp), null, Timeout.Infinite, 1000);
 
            // 计时开始
            TimeCount = 0;
            myTimer.Change(0, 1000); 
        }
 
        // 计时结束
        private void WaitForm1_FormClosed(object sender, FormClosedEventArgs e)
        {
            if (myTimer != null)
            {
                myTimer.Change(Timeout.Infinite, 1000);
                myTimer = null;
            }
        }
 
    }
}

2.封装SplashScreenManager共通类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using DevExpress.XtraSplashScreen;
 
namespace IMS_TOOLS.Unit
{
    public class SplashFormUtil
    {
        /// <summary>
        /// 设置等待窗口的标题
        /// </summary>
        /// <returns></returns>
        public static void SetCaption(string caption)
        {
            if (SplashScreenManager.Default != null && !string.IsNullOrEmpty(caption))
            {
                SplashScreenManager.Default.SetWaitFormCaption(caption);
            }
        }
 
        /// <summary>
        /// 设置等待窗口的描述文字
        /// </summary>
        /// <returns></returns>
        public static void SetDescription(string description)
        {
            if (SplashScreenManager.Default != null && !string.IsNullOrEmpty(description))
            {
                SplashScreenManager.Default.SetWaitFormDescription(description);
            }
        }
 
        /// <summary>
        /// 显示等待窗口
        /// </summary>
        /// <returns></returns>
        public static void ShowSplashScreen(Type type)
        {
            CloseSplashScreen();
            SplashScreenManager.ShowForm(null, type, false, false, true);
        }
 
        /// <summary>
        /// 关闭等待窗口
        /// </summary>
        /// <returns></returns>
        public static void CloseSplashScreen()
        {
            if (SplashScreenManager.Default != null)
            {
                SplashScreenManager.CloseForm(true);
            }
        }
    }
}

3.其他类调用

SplashFormUtil.ShowSplashScreen(typeof(WaitForm1));
   /***耗时长的操作***/
SplashFormUtil.CloseSplashScreen();
