Object Context

[Object Parameters]Main Parameter[/Object]

Executes the external Windows ActiveX control or Java class file, and displays the text of the result.

To embed the results of an external function (which could be a Windows ActiveX DLL or Java class file on any platform) into one of your pages, put an Object context with appropriate parameters into a template. The parameters are sent to the external module, and the result of the external call are displayed as text in place of the context. Any [xxx] tags inside the context are first substituted for their real values before the Object is executed.

Example (normally you would put the following text into a .TPL file on your server and use a web browser to link to it):

[OBJECT objname=MS.CUSTOM[!]
[/!]&call=MyFunction&param1=Hello&param1type=text&param2=2000&param2type=num]
[/OBJECT]

The ActiveX control DLL "MS.CUSTOM" will be loaded and "MyFunction" will be executed with the following parameters:
Parameter 1: Hello Type: text
Parameter 2: 2000 Type: num
