InfoPath Dev

i am looking out for some kind of article or code snippet or some lead/help in creating a custom control that would appear on a web enabled infopath form 2007. I checked out on the net, i could find lot of articles that would allow me to create controls for infopath forms (links shown below), but these controls are to be created as a dotnet usercontrol and using COMInterop, convert and publish it as a ActiveX control, these control cannot be used for a web enabled infopath forms.

IPFS does not support custom controls other than the contact selector.

I think you would need to use a seperate frame and then tie them together via code or create your own custon app.

i would appreciate if you could provide me some code level help or direct me towards an article for implementing a custom control for browser based infopath forms.

This infopath form would be published to a sharepoint site and displayed within a WebPart (XMLFormView) on a ASPX Page.
