Embedding the Controls in a Web Page

Embedding the Controls in a Web Page

The HTML <OBJECT> tag is used to embed ActiveX controls in a Web page. For controls with a graphical user interface, such as the View controls, the <OBJECT> tag is inserted where you want the control to appear on your page. Controls without a user interface, such as the MediaServer control, can be inserted anywhere between the <BODY> and </BODY> tags.

The following code is an example of how to use the <OBJECT> tag to insert the MediaServer control in a Web page:

<OBJECT CLASSID = "clsid:ADB3EC9B-1820-11D1-B062-0000C040BCDB"
ID = MediaServer
CODEBASE = "nstadmin.ocx#Version=4.0.0.1632">
</OBJECT>

In the preceding example, the <OBJECT> tag has only three attributes:

CLASSID. This attribute is used to create an instance of an ActiveX control by assigning to it the Global Class Identifier (CLSID) of the control. Here we intend to launch the MediaServer control. The following table presents the CLSIDs of all the NetShow Theater Server Administration controls.

Control	Class ID
MediaServer	ADB3EC9B-1820-11D1-B062-0000C040BCDB
ClientView	CE0CD7C0-3B6C-11D1-A40A-00600831F336
ServerView	66E9EFF1-36DD-11D1-A5FE-00AA00BF93E3
TitleView	1E1BAAB1-3614-11D1-A5FE-00AA00BF93E3
TraceView	F8B8F885-1FF6-11D1-85F8-0000F8040045

ID. This attribute specifies the instance of the control. This is the name of the object when it is accessed by a script.
CODEBASE. This attribute specifies a Uniform Resource Locator (URL) to the control if it is not on the user's system. Optionally, it can also specify the version number of the control. This attribute is not required; however, it is strongly recommended.

Controls with user interfaces also require HEIGHT and WIDTH attributes to specify the dimensions, in pixels, of the controls.
