How can I make variables from SWFObject dynamic?

1. You will have to include the java script file in the html part of your asp.net application as
<script type="text/javascript" src="swfobject.js"></script>
2. In the code behind, You will have call


// Define the name and type of the client scripts on the page.
    String csname = "swfObjectScript";
    Type cstype = this.GetType();

    // Get a ClientScriptManager reference from the Page class.
    ClientScriptManager cs = Page.ClientScript;
// Check to see if the client script is already registered.
    if (!cs.IsClientScriptBlockRegistered(cstype, csname))
    {
   StringBuilder cstext = new StringBuilder();
            cstext.Append("<script type=\"text/javascript\">");
            cstext.AppendFormat("swfobject.embedSWF(\"{0}\",\"{1}\",\"{2}\",\"{3}\");",value1,myContent,value2,value3);
            cstext.Append("</script>");
      cs.RegisterClientScriptBlock(cstype, csname, cstext.ToString(), false);
    }

** correction of point 2

In the code behind, you have to register the java script using registerclientscriptblock

may be asking this question can be a little silly but I a new in coding... Would you mind to explain me the term "the client script is already register"? register in what?

what happens if the javascript if not registered? How do I register?
THank you again for all your help!

Register  the java script block with the page.  html\javascript is in the aspx (html portion of asp.net web page) and code behind (cs\vb.net) code is in the aspx.cs (code behind portion of the asp.net web page)

registering the client script means that it is being registered with the page. An equivalent java script snippet is emitted at runtime.

Read this for better understanding
http://msdn.microsoft.com/en-us/library/0skaxdwf.aspx

IsClientScriptBlockRegistered method is used to check if its already registered
RegisterClientScriptBlock method is used to register the script block

You cannot register more than one script block with the same key. you can think of Key\Value pairs where keys are unique.

Hope u understand

Hi,
May be I am doing something wrong here, Would you mind to check my code?
There is an error  saying that the Element "script" is missing the its closing tab.
I am guessing somewher ein the AppendForm I forgot to close the script.

Thanks

        protected void Page_Load(object sender, EventArgs e)
        {
            // Define the name and type of the client scripts on the page.
            String csname = "swfObjectScript";
            Type cstype = this.GetType();
            string value1 = "SWFDocuments/SCICalculatorUK.swf";
            string value2 = "myContent";
            string value3 = "600";
            string value4 = "680";
            // Get a ClientScriptManager reference from the Page class.
            ClientScriptManager cs = Page.ClientScript; 
            // Check to see if the client script is already registered.
            if (!cs.IsClientScriptBlockRegistered(cstype, csname))
            {
                System.Text.StringBuilder cstext = new System.Text.StringBuilder();

                //StringBuilder cstext = new StringBuilder();
                cstext.Append("<script type=\"text/javascript\">");
                cstext.AppendFormat("swfobject.embedSWF(\"{0}\",\"{1}\",\"{2}\",\"{3}\");", value1, value2, value3, value4);
                cstext.Append("</script>");
                cs.RegisterClientScriptBlock(cstype, csname, cstext.ToString(), false);
            }
        }

I check and I figured out the problem but still I don't see the Swf in the page.
