Writing AxShockwaveFlash Flash Object to File C#

Question

hi guys,
i was wonder if there is any way one can read-write (or save/load) AxShockwaveFlash Flash Object to a (binary/text)file?

I have a Winform with AxShockwaveFlash Flash Object on it and want it to be save to a
file ,but serialization doesnt not work as type AxShockwaveFlash is not marked for Serialization?
(Basically trying to dynamically write .swf to file.)

Any ideas??

Thanks and regards
Amit

Try the sample provided on this link.

Hi guys,

i tried this and it worked for me.

I dervied a class from AxShockwaveFlashObjects.AxShockwaveFlash and implemented ISerializable interface.

Implemented GetObjectData and serialization constructor . not much coding in them.

[Serializable()]
class MyCustomFlash : AxShockwaveFlashObjects.AxShockwaveFlash, ISerializable
{
    public MyCustomFlash()
    {

    }

    public MyCustomFlash(SerializationInfo info, StreamingContext ctxt)
    {
       //dont think this is required.
        this.OcxState = (State)info.GetValue("ocxstate", typeof(State));              

    }

    #region ISerializable Members
    public void GetObjectData(SerializationInfo info, StreamingContext context)
    {
       //dont think this is required.
       // info.AddValue("movie", this.Movie);
        info.AddValue("ocxstate", this.OcxState);
    }
    #endregion
}

I was using winform. so ensure that you Embed the movie using

    axShockwaveFlash1.EmbedMovie = true;
   //loadMovie follows

Then try Normal binary serialization/deserilzation.

During deserialization , i tried to add the serialized flash to another form.
But keep getting AxHost+InvalidActiveXStateException and the control didnt appear on form . i think the control was not inited on the form.
Just copy designer initialsation code to it .and then it works.

           string serialFilePath = @"E:\test\serialFiles\DataFile.dat";               
            FileStream myFS = new FileStream(serialFilePath, FileMode.Open);
            // Create a binary formatter object to deserialize the data
            BinaryFormatter myBF = new BinaryFormatter();

            MyCustomFlash flashObj;
          //where class MyCustomFlash : AxShockwaveFlashObjects.AxShockwaveFlash, ISerializable

            flashObj = (MyCustomFlash)myBF.Deserialize(myFS);
           //this is code from VS designer..need to initialise flash control
            ((System.ComponentModel.ISupportInitialize)(flashObj)).BeginInit();
            myFS.Close();
            flashObj.Enabled = true;
            this.Controls.Add(flashObj);
            ((System.ComponentModel.ISupportInitialize)(flashObj)).EndInit();

            flashObj.Name = "Axflash";
            flashObj.Visible = true;
            flashObj.Location = new System.Drawing.Point(12, 12);
            flashObj.Size = new System.Drawing.Size(309, 207);

Hope this helps :)

thx
