i am wondering how to build a c# applet. i built a class library with a custom control. but the browser (ie6) fails to render it as an object. do you have some examples to show how to achieve this? by the way, can a c# applet be run under platforms without the .net framework pre-installed?
there's no such concept as a c# "applet". at most, there are custom windows forms controls that are embedded on a page. of course, just like in java, you can't run it if you don't have the corresponding runtime on the client machine. you can use the <object> tag to add it to an html page: (zzj0820注：其實并沒有所謂的c# applet的概念，通常所說的c# applet指的是嵌入到瀏覽器里的窗體控件。當然，跟java類似，必須在客戶端機器上安裝相應的運行時庫才能使用嵌入在html頁面里的object標簽控件)
the class id contains the url of the dll for downloading and the fully qualified name of the class that implements the control. the library must not be placed on the /bin folder of a web application in order to be served by iis/asp.net
下面有兩個簡單的例子，希望有所幫助j

/*
* a simple c# program that displays some text in a webpage.
public class helloworldapplet : system.windows.forms.control {
public helloworldapplet() {
// create a "label" control
label label = new label();
label.text = "hello world!";
label.forecolor = color.blue;
label.font = new font("arial", 24, fontstyle.bold);
label.autosize = true;
// insert the label
controls.add(label);
}

c# applet by lloyd dupont
i want to tell you how to write c# applet, display it in a web page and the requirement.
the requirement first, your c# applet won't work anywhere nor from anywhere. you should put (and test) it on iis, for unknown reason (at last unknown to me) this won't work locally or with apache. btw http://www.brinkster.com make free ".net" hosting.
not any client could display a c# applet, you surely need ie6 and probably .net sdk (at last with these configuration this work everywhere i know).
after you wrote your custom system.windows.forms.control, create it with a parameterless constructor (which will be called by ie) and wrap it in an assembly.
after you could display it very easily in a web page like this:
