visual-studio - Visual C# - InvalidActiveXStateException

Question

尝试将 Flash (.swf) 文件嵌入到我的 Visual C' 表单时出现错误 - 我注意到这是一个相当常见的错误，尽管解决方案对我来说意义不大。
这是我的代码:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using AxShockwaveFlashObjects;
using ShockwaveFlashObjects;

namespace WindowsFormsApplication1
{
    public partial class Form6 : Form
    {
        public Form6()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            Form1 frm1 = new Form1();
            frm1.ShowDialog();

        }

        private void axShockwaveFlash2_Enter(object sender, EventArgs e)
        {

            **//this.axShockwaveFlash1.LoadMovie(0, "C:\\Documents and Settings\\Gary\\My Documents\\Flash File\\CalmBay1.swf");**
        }

        private void Form6_Load(object sender, EventArgs e)
        {
            AxShockwaveFlash axShockwaveFlash = new AxShockwaveFlash(); 
            axShockwaveFlash.Location = new System.Drawing.Point(50, 50);

            this.Controls.Add(axShockwaveFlash);
            **axShockwaveFlash.Movie = ("C:\\Documents and Settings\\Gary\\My Documents\\Flash File\\CalmBay1.swf");**
            //ShockwaveFlash.Size = new System.Drawing.Size(150, 150);// set size as required
            axShockwaveFlash.Play(); 

        }
    }
}

带星号的那一行是错误所在，但正如我所说，我不知道如何解决它!

尽管问这个问题已经几个月了，但我还是遇到了同样的问题。以编程方式创建 AxShockwaveFlash 对象时，您必须初始化:

var flashObj = new AxShockwaveFlash();
((ISupportInitialize) (flashObj)).BeginInit(); // <--
flashObj.Dock = DockStyle.Fill;
flashObj.Enabled = true;
((ISupportInitialize) (flashObj)).EndInit(); // <--

Controls.Add(flashObj);

flashObj.AutoSize = true; // All of these properties won't work unless the component has been initialized
flashObj.ScaleMode = 1;
flashObj.AlignMode = 0;
flashObj.LoadMovie(0, @"movie.swf");
flashObj.Stop();
flashObj.Play();

希望这将为 future 的读者节省一些时间。
