Webmaster Forum / Flash / Flash Remoting / November 2004

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 Vivek
