FlashVars won't work in VB

I am trying to create a simple FlashPlayer in VB. I used the following:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load

Dim axShockwaveFlash As New AxShockwaveFlash

axShockwaveFlash.Location = New System.Drawing.Point(10, 10)

Me.Controls.Add(axShockwaveFlash)

axShockwaveFlash.Movie = "D:\Projects\Flash\Learning\Learning-2.swf"



axShockwaveFlash.Size = New System.Drawing.Size(400, 400)

Dim flvFileName As String = "D:\Video\Clips\PoliceBikeChase.flv"

Try

axShockwaveFlash.FlashVars = "flvurl=" & flvFileName

'axShockwaveFlash.CallFunction("<invoke name=""loadFLV""
returntype=""xml""><arguments><string>" + flvFileName +
"</string></arguments></invoke>")

' The above generates an error

Catch ex As Exception

End Try

axShockwaveFlash.Play()



End Sub

When I inspect FlashVars, it shows as blank, both before and after the
statement inside Try above. Also the commented out statement immediately
below that generates and error:

{"Error HRESULT E_FAIL has been returned from a call to a COM component."}
System.Exception

How do I get it to work?

Thanx in advance,
 
Try dropping the control on a form, from the toolbox, instead of creating it
in the form load event.

Note that after adding Shockwave Flash Object control to your toolbox,
it has a bug with VS when you try to place it fails, and you need to
also reference OLE Automation in COM tab to solve error.

Formerly, i remember the problem was being solved by rebuilding
project more than one time, having flash9f, i couldn't confirm
rebuilding is a solution, but OLE Automation still works to make
Shockwave Flash Object work.

Hope this helps,

Yes, that is why I did not insert the control from the Toolbox (as Dick
suggested in the previous message) - it gives all kinds of errors. What
exactly do you mean by "reference OLE Automation in COM tab to solve
error."?

After you added "Shockwave Flash Object" in your toolbox by right-
clicking -> "Choose Items" in Toolbox, also right-click your project
in Solution Explorer -> "add reference", look at "COM" tab, select
"OLE Automation" to add reference, then re-try placing the flash
control.

I don't know why, after updating flash to Flash9f.ocx, rebuilding does
not work anylonger but it seems OLE Automation does.

Thanks,

That worked! At least in part. Now the line:
AxShockwaveFlash.CallFunction("<invoke name=""loadFLV""
returntype=""xml""><arguments><string>" & flvFileName &
"</string></arguments></invoke>"

does not give an error message, Now I have to figure out how to write a
function in Flash (don't know much about Flash). But the FlashVars still
remain blank. Strange...

I was mistaken, it doesn't work! I still get the same error - it just
happened to be in Try Catch without any handler. Also, could you point me
to a resource on how I could write the function LoadFLV in Flash?

Ok, as you added flash control to your form also with referencing OLE
Automation, as far as i know it supports SWF extensions natively and
look at "Movie" at properties window of flash control and enter sth
like: http://www.domain.com/file.swf or a local swf path.

Flash player control may not be able to play FLV files alone as it may
require a FLV player which is needed to be embedded like in popular
video sharing websites.
