Creating a custom file type and having it open in the same window by default?
 

I’m trying to design a file type [XPI] used by Firefox and other Mozilla products to auto-open when clicked on opening in any current browser window you have. I was successful in making the file type but getting it to open in the same window was a whole different story. Can anyone tell me how to correctly write the commands in Edit [Under Folder Options > File Types > then choosing the file type > Edit] so that they do in fact open in a current window than trying to open in a completely new one?

Thanks.

Okay... I've gone ahead and pulled the entries IE uses in the registry to open html files in the same window via the context menu:
Somehow I'm getting the hint I need to use DDexec commands [I have no idea what those are]?

Anyone?

Surely someone must know... :(

You might have better luck over in Tilted Programming

I'm not too sure about that...

I realize that this isn't really programming at all. However, since you didn't seem to be having much luck here, I thought I'd bring that up as a possible alternative. Since our programming forums won't work, have you tried <a href="http://www.neowin.net/forum">Neowin</a>? There are alot of knowlegable people there as well. If that doesn't yield a result, I'm afraid I'm out of ideas. Sorry I coudln't be of more help.
