HlinkNavigateString Navigating in same browser

Hi,

My ActiveX control calls HlinkNavigateString function for hyperlinking.

If the use has two browsers installed
e.g. IE and FireFox, and FireFox is the default browser,

If I HlinkNavigateString when the page is opened in IE,
HlinkNavigateString opens the specified link in the default browser, i.e. FireFox.

What should I use to open the link in current browser window instead of the default browse window

Thanks,
Praj.
