how to set parameter for activex control.

hi, i'm working in vs2005.
i bought ip camera and i wanna develop my program to use activex control(.ocx) in software.
it works in html when i set parameter in html code like this...
<OBJECT ID="IPCam_Plugin" CLASSID=clsid:b015b944-7316-49ae-ac84-acca9379ea32 ALIGN="CENTER" WIDTH="320" HEIGHT="240" Codebase="/IPCamPluginMJPEG.cab#version=1,0,7,0">
<PARAM name="IP" value="192.168.1.200">
<PARAM name="Port" value="5150">
<PARAM name="Login" value="5BBB31144D">
<PARAM name="Password" value="E39FACB1A2">
<PARAM name="Code" value="899EDF974454DDB53917AD">
<PARAM name="Debug" value="0">
</OBJECT>
....
but i want to use application in this control.
when i add activex control in vs2005, i can see message to set parameter for this ocx.
how can i fix it?
can i get snippet code?
and any suggestion will be welcome.
best regards.
so

I would think they would be exposed as properties or functions of the class.
