Check to see if Active X Control is installed and display instructions if needed

[Jay Douglas]

I have a 3rd parth ActiveX control that needs to be displayed within a web
page. If the user doesn't have the ActiveX control installed on their
computer I would like to display instructions on installing the ActiveX
control (using IE v6 SP 2)..

I'm having a hard time determining client or server side if the ActiveX
control is installed.

If you have any links or suggestions I would appreciated them.

Thanks.

When you use the <object> tag and the browser cannot create the
control, it will instead display any HTML markup you have inside.

For example, try something like:

<OBJECT CLASSID="...">
<SPAN STYLE="color:red">To install this control...
</SPAN>
</OBJECT>

You can do something like
if(Request.Browser.ActiveXControl)
{
Response.Write("<script>var obj = server.createobject("customcontrol");
if (obj == null) alert('need control blahble')</script>");

}
roughly
