加载mxd 报异常System.Windows.Forms.AxHost+InvalidActiveXStateException

Question

加载mxd 在执行CheckMxFile方法的时候，报异常System.Windows.Forms.AxHost+InvalidActiveXStateException
新手 不知道为什么？ 代码贴出来：
public partial class Form1 : Form
    {
        public System.Windows.Forms.OpenFileDialog openFileDialog1;
        public ESRI.ArcGIS.Controls.AxMapControl axMapControl1;        public Form1()
        {
            InitializeComponent();
        }        private void button1_Click_1(object sender, EventArgs e)
        {
            openFileDialog1 = new System.Windows.Forms.OpenFileDialog();
            axMapControl1 = new ESRI.ArcGIS.Controls.AxMapControl();
            openFileDialog1.Title = "打开地图文档！";
            openFileDialog1.Filter = "Map Documents (*.mxd)|*.mxd";
            openFileDialog1.ShowDialog();
            string mxFilePath = openFileDialog1.FileName;
            if (mxFilePath == "")
            {
                return;
            }
            if (axMapControl1.CheckMxFile(mxFilePath) == true)
            {
                axMapControl1.LoadMxFile(mxFilePath, Type.Missing, "");
                axMapControl1.Enabled = true;
            }
            else
            {
                MessageBox.Show(mxFilePath + " is not a valid ArcMap document");
                return;
            }
        }
    }

转自http://hi.baidu.com/chlinet/blog/item/7dde2a7fe9d2a40029388a6b.html引发类型为“System.Windows.Forms.AxHost+InvalidActiveXStateException”的异常 解决办法出现题目的异常，多是引用第三方控件引起的。在NEW时，需要初始化该对象。             AxESACTIVEXLib.AxESActiveX ax = new AxESACTIVEXLib.AxESActiveX();            ((System.ComponentModel.ISupportInitialize)(this.ax)).BeginInit();
            this.Controls.Add(ax);
            ((System.ComponentModel.ISupportInitialize)(this.ax)).EndInit();这样就OK了。
