<！ -
body {}
＃ box1 {< span class =code-attribute> position ： 绝对; top ： 0px; left ： 0px; width ： 150px; height ： 35px; z-index ： 1; }
- >
< / style >
< / head >
<跨度类= 代码关键字>< <跨度类= 代码leadattribute>体 <跨度类=代码 - 属性> bgcolor = ＃FFFFFF >
< div id = <跨度类= 代码关键字> BOX1 <跨度类= 代码关键字 >>
<跨度类= 代码关键字>< applet
codebase = ../ applets /
< span class =code-attribute> archive = s7api.jar，s7util.jar，s7gui.jar，s7applets.jar
code = de.siemens.simaticnet.itcp.applets.S7GetApplet.class
name = Get_Applet_Name
可能 script < span class =code-attribute>
< span class =code-attribute> width = 150
height = 35
hspace = 0
vspace = 0
align = top >
< param name = RACK value = 0 >
< param 名称 = SLOT value = 0 >
< ; param name < span class =code-keyword> = LANGUAGE 值 = en >
< param name = BACKGROUNDCOLOR value = 0xFFFFFF >
< param name = 编辑 value = true >
< param name = FORMAT value = Var_Name_1 = \F >
< param 名称 = VARTYPE value = 0x08 >
< param name = VARCNT value = 1 >
< param 名称 = VARAREA value = 0x84 >
< param name = VARSUBAREA value = 1 >
< param name = VAROFFSET value = 0 >
< param name = CYCLETIME value = 5000 >
< / ap plet >
< / div >
< / body >
< / html >
我想从html获取applet控件并读取值。但是，我无法从我的C＃代码中读取applet控件。
请帮忙。谢谢。

Hi,
I'm facing a problem with read data from Java control in html to C#. Here is code in html:

<style type="text/css">

body { }
#box1 { position:absolute; top:0px; left:0px; width: 150px; height: 35px; z-index:1; }
-->
</style>
</head>
<body bgcolor="#FFFFFF">
<div id="box1">
<applet
codebase ="../applets/"
archive ="s7api.jar, s7util.jar, s7gui.jar, s7applets.jar"
code ="de.siemens.simaticnet.itcp.applets.S7GetApplet.class"
name ="Get_Applet_Name"
mayscript
width ="150"
height ="35"
hspace ="0"
vspace ="0"
align ="top">
<param name="RACK" value="0">
<param name="SLOT" value="0">
<param name="LANGUAGE" value="en">
<param name="BACKGROUNDCOLOR" value="0xFFFFFF">
<param name="EDIT" value="true">
<param name="FORMAT" value="Var_Name_1 = \F ">
<param name="VARTYPE" value="0x08">
<param name="VARCNT" value="1">
<param name="VARAREA" value="0x84">
<param name="VARSUBAREA" value="1">
<param name="VAROFFSET" value="0">
<param name="CYCLETIME" value="5000">
</applet>
</div>
</body>
</html>
I want to get the applet control from html and read the value. However, I cannot read the applet control from my C# code.
Please help. Thank you.
