海康二次开发学习笔记5-二次开发小技巧

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();}
