切换界面时界面刷新慢，怎么解决

headgo 2011-04-09 07:05:07
刚接触VC#不久，做了一个界面，上面有个tab，里面放置了3个按键，20个label和20tTextBox，这些空间放置在几个groupBox中进行分组。程序才刚刚进行界面设计，没有其他操作。发现在本程序内部从其他tab页切换到这个tab页时，甚至从其他程序切换到本程序时，这个界面刷新比较慢，能明显看到控件重画的过程。

目前主流机器，所以不应该是机器慢的问题。

也听说过双缓存，在界面构造函数中调用如下代码也不起作用：
this.SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint | ControlStyles.DoubleBuffer, true);

刷新慢尽管不影响程序使用功能，但给使用者的体验肯定不好，所以希望解决这个问题，请大家赐教。

GDI的性能本来就不高，你也可以测试用WPF来开发你的应用。

偶用的是VS2005，.net 2.0。WPF是.net3.0的容。现在VS2005是不是太落后了。

同一个界面上的控件太多了 winForm就是这样的 尝试重新布局控件，比如做做分组，放在不同的TabControl页中。

能明显看出画控件的步骤？

估计真是电脑硬件问题。~

可能描述有些夸张，但能明显感觉到闪烁是确实的，机子是主流机器。

论坛有没有上传附件的功能？
在回复里上传代码太麻烦了，稍微复杂点的界面就超过10000字符了，再加上只能连续3次回复的限制，上传代码好麻烦啊。

谢谢各位，受限于论坛只能连续发3个回复，代码没有发完全。今天继续。
另外要强调一下的是，界面构造函数和Load函数中可以说几乎没有自己写的代码，别的地方也没有代码，可以说就是一个原始的界面设计。但在进行程序切换或tab切换时能明显感觉到闪烁。

程序已经被我简化成最简单了，只有三个文件，出了设置双缓存代码以外，没有任何自写的代码了：
Program.cs文件：


using System;

using System.Collections.Generic;

using System.Windows.Forms;



namespace HMI

{

    static class Program

    {



        /// <summary>

        /// 应用程序的主入口点。

        /// </summary>

        [STAThread]

        static void Main()

        {

            Application.EnableVisualStyles();

            Application.SetCompatibleTextRenderingDefault(false);

            Application.Run(new MainForm());

        }



    }

}


文件MainForm.cs：


using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Reflection;

using System.Text;

using System.Windows.Forms;

using System.Diagnostics;





namespace HMI

{

    public partial class MainForm : Form

    {



        public MainForm()

        {

            InitializeComponent();





            #region 设置双缓存，解决闪烁问题

            //Type type = tabPage1.GetType();

            //PropertyInfo pi = type.GetProperty("DoubleBuffered", BindingFlags.Instance | BindingFlags.NonPublic);

            //pi.SetValue(tabPage1, true, null);



            this.SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint | ControlStyles.DoubleBuffer, true);// 设置双缓冲，防止图像抖动,忽略系统消息，防止图像闪烁

            #endregion

        }



        private void MainForm_Load(object sender, EventArgs e)

        {



        }



        private void MenuItemExit_Click(object sender, EventArgs e)

        {

            this.Close();

        }      



    }

}

我觉得有可能是系统的问题，没听说过切换个tab，还卡的。
你放到另一台电脑上看看还卡不卡

load事件和构造方法检查一下，估计是程序问题，我们用过4个tab的也不慢
