如何控制C＃windows应用程序中的闪烁问题以显示串口数据？

本文介绍了如何控制C＃windows应用程序中的闪烁问题以显示串口数据？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 大家好， 我在串口显示标签中的数据。数据显示正常，但数据闪烁的标签控件。如何停止这个闪烁的问题是为了正确显示数据。 这是我的代码 - Hello all,I am showing data in label from serial port.Data display is OK but the label control on which data is flickering.How can i stop this flickering problem to display data properly.Here is my code-private void button1_Click(object sender, EventArgs e) { SerialPort mySerialPort = new SerialPort("COM1"); mySerialPort.BaudRate = 9600; mySerialPort.Parity = Parity.None; mySerialPort.StopBits = StopBits.One; mySerialPort.DataBits = 8; mySerialPort.Handshake = Handshake.None; mySerialPort.RtsEnable = true; SerialPort sp = (SerialPort)sender; label1.Text = sp.ReadExisting(); mySerialPort.Open(); mySerialPort.Close(); } 这里是新代码 - here is the new code--public partial class MainForm : Form { SerialPortManager _spManager; public MainForm() { InitializeComponent(); DoubleBuffered = true; UserInitialization(); } private void UserInitialization() { _spManager = new SerialPortManager(); SerialSettings mySerialSettings = _spManager.CurrentSerialSettings; serialSettingsBindingSource.DataSource = mySerialSettings; portNameComboBox.DataSource = mySerialSettings.PortNameCollection; baudRateComboBox.DataSource = mySerialSettings.BaudRateCollection; dataBitsComboBox.DataSource = mySerialSettings.DataBitsCollection; parityComboBox.DataSource = Enum.GetValues(typeof(System.IO.Ports.Parity)); stopBitsComboBox.DataSource = Enum.GetValues(typeof(System.IO.Ports.StopBits)); _spManager.NewSerialDataRecieved += new EventHandler<SerialDataEventArgs>(_spManager_NewSerialDataRecieved); this.FormClosing += new FormClosingEventHandler(MainForm_FormClosing); } private void MainForm_FormClosing(object sender, FormClosingEventArgs e) { _spManager.Dispose(); } void _spManager_NewSerialDataRecieved(object sender, SerialDataEventArgs e) { if (this.InvokeRequired) { this.BeginInvoke(new EventHandler<SerialDataEventArgs>(_spManager_NewSerialDataRecieved), new object[] { sender, e }); return; } int maxTextLength = 1000; // maximum text length in text box if (tbData.TextLength > maxTextLength) tbData.Text = tbData.Text.Remove(0, tbData.TextLength - maxTextLength); string str = Encoding.ASCII.GetString(e.Data); tbData.AppendText(str); tbData.ScrollToCaret(); DoubleBuffered = true; label1.Text = str; } private void btnStart_Click(object sender, EventArgs e) { _spManager.StartListening(); } private void btnStop_Click(object sender, EventArgs e) { _spManager.StopListening(); } } 谢谢 我尝试了什么： 我用过以下代码 - protected override CreateParams CreateParams { 得到{ CreateParams cp = base.CreateParams; cp.ExStyle | = 0x02000000; //打开WS_EX_COMPOSITED 返回cp; } } ThanksWhat I have tried:I have used below code-protected override CreateParams CreateParams { get { CreateParams cp = base.CreateParams; cp.ExStyle |= 0x02000000; // Turn on WS_EX_COMPOSITED return cp; }}推荐答案 尝试将DoubleBuffered设置为true：控制。 DoubleBuffered属性（System.Windows.Forms） [ ^ ] - 从标签开始，然后是表格。Try setting DoubleBuffered to true: Control.DoubleBuffered Property (System.Windows.Forms)[^] - start with the label, and then the form. 这篇关于如何控制C＃windows应用程序中的闪烁问题以显示串口数据？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
