使用Windows窗体主机在WPF中嵌入SWF文件？ [英] Embedding SWF file in WPF using Windows Forms Host?

问题描述

我目前需要在我的WPF表单中嵌入一个SWF文件。我读过它，至少有两种方法可以实现这一点：

• 将SWF嵌入到HTML文件中，并将后者嵌入到我的form。


• 使用AxShockwaveFlashObjects程序集嵌入SWF。因为这是为了在WinForms中使用，而不是在WPF中使用，所以我将不得不使用Windows窗体主机，并将Shockwave Flash Object放入其中。

由于我的应用程序的一些要求（基本上是shockwave对象的GetVariable函数），我选择了第二个选项。我把Windows窗体主机放在我的WPF窗体中，并将​​下面的代码放在它的构造函数中：

pre $ public MainWindow（）
{
InitializeComponent（）;

AxShockwaveFlash flash = new AxShockwaveFlash（）;

flash.Location = new System.Drawing.Point（0，0）;
flash.Size = new System.Drawing.Size（200，200）;
flash.Enabled = true;
flash.Movie =http://www.example.com/file.swf;

windowsFormsHost1.Child = flash;

$ / code>

但是，当我调试代码，我得到这个错误启动： p>

'类型'Flash_in_WPF.MainWindow'中与指定绑定约束匹配的构造函数的调用引发了一个异常'行号'4'和

如果我移动该代码以在单击按钮时运行，则会得到不同的错误消息： / b>

引发类型为System.Windows.Forms.AxHost + InvalidActiveXStateException的异常。

为什么我会收到这些错误？

编辑：解决了！将整个初始化代码移动到Grid_Loaded事件而不是在我的ctor。

预先感谢

解决方案

解决它！我想应该把问题设置为已解决。

原来我需要将整个初始化代码移到Grid_Loaded事件中，而不是在我的ctor中。

I'm currently in need of embedding an SWF file inside my WPF form. I read about it and there are at least two ways to accomplish this:

• Embedding the SWF inside an HTML file and embed the latter in my form.
• Embedding the SWF using the "AxShockwaveFlashObjects" assemblies. since this is meant to be used in WinForms and not in WPF, I will have to use a Windows Forms Host and put the Shockwave Flash Object inside of it.

Because of some of the requirements of my application (basically the "GetVariable" function of the shockwave object) I chose the second option. I put a Windows Forms Host in my WPF form, and put the following code in its constructor:

    public MainWindow()
    {
        InitializeComponent();

        AxShockwaveFlash flash = new AxShockwaveFlash();

        flash.Location = new System.Drawing.Point(0, 0);
        flash.Size = new System.Drawing.Size(200, 200);
        flash.Enabled = true;
        flash.Movie = "http://www.example.com/file.swf";

        windowsFormsHost1.Child = flash;
    }

But when I debug the code, I get this error on startup:

'The invocation of the constructor on type 'Flash_in_WPF.MainWindow' that matches the specified binding constraints threw an exception.' Line number '4' and line position '106'.

If I move that code to run when a button is clicked, I get a different error message:

Exception of type 'System.Windows.Forms.AxHost+InvalidActiveXStateException' was thrown.

Why am I getting these errors?

Edit: solved it! turns out I needed to move the whole initialization code to the "Grid_Loaded" event instead of in my ctor.

Thanks in advance

解决方案

Solved it! Figured I should set the question as solved.

Turns out I needed to move the whole initialization code to the "Grid_Loaded" event instead of in my ctor.
