Register an ActiveX Control as Viewer for a MIME Type

Hi,

i have written an ActiveX Control which displays compressed images. In order to use this control as a viewer for this kind of images (in IE for example) i have create and register a MIME type "image/ABC". On my HTML page i want to use the EMBED tag like this:

<EMBED SRC="image.abc" TYPE="image/ABC" ..... >

Now if i read this HTML page my ActiveX Control start correctly (because of the MIME type), but i do not know, how to transmit the SRC string to the right property of my control.

Thanks in advance!
