ArcEngine开发问题总结

问题：遇到'异常来自 HRESULT:0x80040228’

解决方法：添加一个license控件就行了.

问题：遇到‘ArcGIS version not specified. You must call RuntimeManager.Bind before creating any ArcGIS components.’

解决方法：

View Code 
/// <summary>
        /// 应用程序的主入口点。
        /// </summary>
        [STAThread]
        static void Main()
        {
        //添加一下语句    ESRI.ArcGIS.RuntimeManager.Bind(ESRI.ArcGIS.ProductCode.EngineOrDesktop);
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Form1());
        }

 

问题：

解决办法：

将嵌入互操作类型设置为false。
