HtmlDocument and Object Tag

Greetings,

i have a question regarding the HtmlDocument class. Im building a small app that integrates the WebBrowser. At runtime i want to add applets to the source code.

Although i can add the applets, there is a small problem:

This is the code i want to generate in the Browser:
<object style="position:absolute; top: 1px; left: 1px" codetype="application/java" classid="..." width="10" height="10">
<param name="code" value="..." />
<param name="codebase" value="..." />
</object>

Unfortunally, i cant seem to be able to add any child elements to the object element... this is the code i am using:

public static void AddNewEditor(HtmlDocument document, Point point)

{

HtmlElement element, param;

element = document.CreateElement("object");

element.SetAttribute("codetype", "application/java");

element.SetAttribute("classid", "...");

element.SetAttribute("id", "editor");

element.Style = "width=1; height=1; position:absolute; top: " + point.Y + "px; left:
" + point.X + "px";

document.Body.AppendChild(element);

param = document.CreateElement("param");

param.SetAttribute("name", "code");

param.SetAttribute("value", "...");

element.AppendChild(param);

param = document.CreateElement("param");

param.SetAttribute("name", "codebase");

param.SetAttribute("value", "...");

element.AppendChild(param);

}

i cant seem to call the element.AppendChild(param);... but it should ve a valid child for object...

I tried all i could think of, as editing the inner html of the object tag, etc, but nothng seems to work... Sad Any clue??

Thanks in advance Big Smile

In most cases you cannot modify the <param>s of an <object> tag after it has been rendered to the browser, try appending the params to the <object> before appending the <object> to the document <body>.

Ron, thanks for your reply Smile

Actually as soon as i create the object tag, it has the property CanHaveChildren as false.

Trying to add a param element creates an exception, even before adding the object to the HtmlDocument.

Creating other tag's, like div, allows the HtmlElement to have children... but what i really need is to add an applet to the html... You dont know of a workaround?

Finally i've been able to had the applet... instead of using the <object> tag, i used the <applet> and defined all the params as attributes to the tag (This should not be done this way, i read somewhere, as the <object> is the correct form but... :)

Anyway, now the applet does not run unless there was an applet running before on the page i am changing. Does anyone know how to make my instance of the WebBrowser to start the JVM?

Thanks,
