Help - Flash Remoting with .NET - data does not get displayed

P: n/a
Hi,

I have a problem with Flash remoting via .NET . I seem to have all the
code right, but flash does not seem to display the data at all.

Here's is what Ive done so far...

(1) Ive installed Flash Remoting MX, and copied over the contents of
wwwroot\flashremoting\bin into my web application's folder\bin.

(2) In my web application, I have included the FlashGateway.dll as a
reference.

(3) The aspx file that holds the embed tag for the flash control has
the following code:

<OBJECT id="template1"
codeBase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,0,0"
height="550" width="600" align="middle"
classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000"
VIEWASTEXT>
<PARAM NAME="_cx" VALUE="15875">
<PARAM NAME="_cy" VALUE="14552">
<PARAM NAME="FlashVars" VALUE="">
<PARAM NAME="Movie"
VALUE="template.swf?gatewayPath=http://localhost/MyWebApp/gateway.aspx">
<PARAM NAME="Src"
VALUE="template.swf?gatewayPath=http://localhost/MyWebApp/gateway.aspx">
<PARAM NAME="WMode" VALUE="Window">
<PARAM NAME="Play" VALUE="-1">
<PARAM NAME="Loop" VALUE="-1">
<PARAM NAME="Quality" VALUE="High">
<PARAM NAME="SAlign" VALUE="">
<PARAM NAME="Menu" VALUE="-1">
<PARAM NAME="Base" VALUE="">
<PARAM NAME="AllowScriptAccess" VALUE="sameDomain">
<PARAM NAME="Scale" VALUE="NoBorder">
<PARAM NAME="DeviceFont" VALUE="0">
<PARAM NAME="EmbedMovie" VALUE="0">
<PARAM NAME="BGColor" VALUE="FFFFFF">
<PARAM NAME="SWRemote" VALUE="">
<PARAM NAME="MovieData" VALUE="">
<PARAM NAME="SeamlessTabbing" VALUE="1">
<embed src="template.swf?gatewayPath=http://localhost/MyWebApp/gateway.aspx"
width="650" height="600" id="Template" align="middle"/>
</embed>
</OBJECT>

(4) The gateway.aspx file referred to is a blank (default) aspx file
available in the Web App's path.

(5) The flash file "template.swf" is also available in the Web App's
path.

(6) The "template.swf" file has the code burnt in to refer to
"dataToFlash.aspx" to get the input data in the form of an XML string.

(7) In the "dataToFlash.aspx" I have the Register directive:

<%@ Page Language="vb" AutoEventWireup="false"
Codebehind="dataToFlash.aspx.vb" Inherits="VentureMap.dataToFlash"%>
<%@ Register TagPrefix="MM" Namespace="FlashGateway"
Assembly="flashgateway" %>

(8) The "dataToFlash.aspx" has the default Web Form Designer code
after adding the Register directive:

#Region " Web Form Designer Generated Code "

'This call is required by the Web Form Designer.
<System.Diagnostics.DebuggerStepThrough()> Private Sub
InitializeComponent()

End Sub
Protected WithEvents Flash As FlashGateway.Flash

'NOTE: The following placeholder declaration is required by the
Web Form Designer.
'Do not delete or move it.
Private designerPlaceholderDeclaration As System.Object

Private Sub Page_Init(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Init
'CODEGEN: This method call is required by the Web Form
Designer
'Do not modify it using the code editor.
InitializeComponent()
End Sub

#End Region

(9) The function call to Page_Load in "dataToFlash.aspx" is as
follows:

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
'Put user code to initialize the page here

Dim xmlDoc As New XmlDocument
xmlDoc.Load("XMLTemplate.xml")
Dim sw As New StringWriter
Dim xw As New XmlTextWriter(sw)
xmlDoc.WriteTo(xw)
Dim strXMLOutput As String
strXMLOutput = sw.ToString()

Flash.Result = strXMLOutput

End Sub

I have tested that the "strXMLOutput" variable has the correct and
entire XML output from the xml file.

(10) The "template.swf" has the script built in to read the input XML
string, parse it, and display data within the flash controls.

But the flash control on the browser, never seems to read the data and
display it.

Is there anything Im missing ? Are any of these declarations /
object-naming portions case-sensitive ?

Ive tried everything I could find on various message groups / Google /
Macromedia FAQ.

If anyone could help me out, it would be just great.

Thanks,
Uma
