问题
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

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