二次开发小技巧

1. VM安装目录

Samples内包含C#,QT,VC应用程序

Documetnations内包含C#和C语言的帮助文档

2. 错误码

        private void button4_Click(object sender, EventArgs e)
        {
            try
            {
                VmSolution.Load(textBox1.Text);
                listBox1.Items.Add("方案加载成功.");
                listBox1.TopIndex = listBox1.Items.Count - 1;
            }
            catch (VmException ex)
            {

                MessageBox.Show("VM SDK异常:" + Convert.ToString(ex.errorCode, 16));
            }
            catch (Exception ex) {
                MessageBox.Show("系统异常:"+ex.Message);
            }
            
        }

3. 资源管理

程序启动时杀死进程,关闭VM

        public Form1()
        {
            KillProcess("VisionMasterServerApp");
            KillProcess("VisionMaster");
            KillProcess("VmModuleProxy.exe");
            InitializeComponent();
            
        }

        private void KillProcess(string strKillName)
        {
            foreach (var item in System.Diagnostics.Process.GetProcesses())
            {
                if (item.ProcessName.Contains(strKillName))
                {
                    try
                    {
                        item.Kill();
                        item.WaitForExit();
                    }
                    catch (Exception ex)
                    {

                        Console.WriteLine(ex.Message);
                    }
                }
            }
        }

程序关闭时释放资源

        private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            VmSolution.Instance.Dispose();
        }
