FiLeTyPeS, 2 Q's, (Don't need to be guru tu answer this)

[kedaman]

Ok, i've done some rearch about filetypes in registry, to make my recent app complete. I'm thinking about making a dll, for you that want to create your own filetypes fast and easy. So i have to ask you guys two qwestions.

1. Have anyone done this already? If, so could you send me the dll (or whatever)

2. When i'm ready with this, do you want to have my dll? I suppose there must be at least some people out there who have tried to make their own filetypes

'The filetype type is pretty self-explanatory.
'Extension contains the file type extension.
'Proper name is the name of the type, which you would
'refer to the type as (do not use spaces).
'FullName is the description of the file type.
'ContentType is the description that you would see
'in your Internet browser, if you were to download a
'file of this type. You could think of the extension
'as the "shortcut key", the proper name as the "name",
'and the fullname as the "caption".

'This Commands part of the filetype contains
'the "verbs" for the file type. When you right-click on
'a file of this type, you would see these options.
'Open is set as the default "verb", so when you double
'click on the file type, it executes the command associated
'with "Open". You can add others, such as "Print" as needed.

'Be careful with registry editing, as it can have disasterous effects.

Ok, thanks,

OK, I have some more Q's here:
1. The association work's fine, but i have to restart for the icon and file type name to show. How do i update them immediately?
2. I need to associate to mp3's with two extra commands. I know how to do it but,
a) Will winamp be affected?
b) What happens if winamp terminates it's association with mp3's?
c) If winamp's not installed my assosiation is still needed, but when winamp installs or reassociate with mp3's will it's command appear next to mine? I wan't my commands to be always come in second.
3. There are two copies of the filetype in registry, in root and localmachine. The second is created automatically, will it also remove automatically, if i terminate my association by removing the keys in the first?

Also who those who want's to know what i'm doing, i'm still working on my mp3-integrated lyrics editor for winamp.
And if anyone is still interested in solving my so easy scrolling dilemma, just reply here, (ok it's not that easy as even fox didn't manage to get it work properly)

I think if you install Winamp after your App. It will erase your commands and replace it with it's own.
