我刚刚关闭了退出的应用程序,并收到Win32异常错误创建窗口句柄可能会这样做

本文关键字:创建 错误 Win32 窗口句柄 异常 这样做 退出 应用程序 | 更新日期: 2024-11-03 16:33:41

我在某处读到关闭应用程序时需要处理对象?

我有这个属性,我在拖曳函数中使用它们,我需要调用它们,因为我使用后台工作者。

在大多数情况下,当我关闭我的应用程序时,还可以,但现在我得到了这个异常。

private string CpuTextLabelProperty
        {
            set
            {
                if (InvokeRequired)
                {
                    BeginInvoke(new Action(() => CpuTemperature_label.Text = value), null);
                }
            }
            get
            {
                return CpuTemperature_label.Text;
            }
        }
        private Point CpuLocationLabelProperty
        {
            set
            {
                if (InvokeRequired)
                {
                    BeginInvoke(new Action(() => CpuTemperature_label.Location = new Point(210, 200)), null);
                }
            }
            get
            {
                return CpuTemperature_label.Location;
            }
        }
        private string GpuTextLabelProperty
        {
            set
            {
                if (InvokeRequired)
                {
                    BeginInvoke(new Action(() => GpuTemperature_label.Text = value), null);
                }
            }
            get
            {
                return GpuTemperature_label.Text;
            }
        }
        private Point GpuLocationLabelProperty
        {
            set
            {
                if (InvokeRequired)
                {
                    BeginInvoke(new Action(() => GpuTemperature_label.Location= new Point(210,100)), null);
                }
            }
            get
            {
                return GpuTemperature_label.Location;
            }
        }
        private string Label4TextProperty
        {
            set
            {
                if (InvokeRequired)
                {
                    BeginInvoke(new Action(() => label4.Text = value), null);
                }
            }

        }

例外是在属性上:GpuTextLabel属性在获取行中:

返回GpuTemperature_label。发短信;

Win32异常 - 创建窗口句柄时出错

我的 Form1 结束活动:

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            if (MessageBox.Show("Are you Sure you want to Exit. Click Yes to Confirm and No to continue", "WinForm", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.No)
            {
                e.Cancel = true;
            }
            else
            {
                this.BeginInvoke((MethodInvoker)delegate { this.Close(); }); 
            }
        }

如果我需要处理一些东西?又如何?

这是使用属性的函数:
