; Features automatic backup system and UPDATEFILEASSOC macro for
|
|
; shell change notification.

|
|
; |> How to use <|
|
|
; To associate a file with an application so you can double-click it in explorer, use
|
|
; the APP_ASSOCIATE macro like this:
|
|
;
|
|
; Example:
|
|
; !insertmacro APP_ASSOCIATE "txt" "myapp.textfile" "$INSTDIR\myapp.exe,0" \
|
|
; "Open with myapp" "$INSTDIR\myapp.exe $\"%1$\""
|
|
;
|
|
; Never insert the APP_ASSOCIATE macro multiple times, it is only meant
|
|
; to associate an application with a single file and using the
|
|
; the "open" verb as default. To add more verbs (actions) to a file
|
|
; use the APP_ASSOCIATE_ADDVERB macro.
|
|
;
|
|
; Example:
|
|
; !insertmacro APP_ASSOCIATE_ADDVERB "myapp.textfile" "edit" "Edit with myapp" \
|
|
; "$INSTDIR\myapp.exe /edit $\"%1$\""
|
|
;
|
|
; To have access to more options when registering the file association use the
|
|
; APP_ASSOCIATE_EX macro. Here you can specify the verb and what verb is to be the
|
|
; standard action (default verb).
|
|
;
|
|
; And finally: To remove the association from the registry use the APP_UNASSOCIATE
|
|
; macro. Here is another example just to wrap it up:
|
|
; !insertmacro APP_UNASSOCIATE "txt" "myapp.textfile"
|
|
;
|
|
; |> Note <|
|
|
; When defining your file class string always use the short form of your application title
|
|
; then a period (dot) and the type of file. This keeps the file class sort of unique.
|
|
; Examples:
|
|
; Winamp.Playlist
|
|
; NSIS.Script
|
|
; Photoshop.JPEGFile
|
|
;
|
|
; |> Tech info <|
|
|
; The registry key layout for a file association is:
|
|
; HKEY_CLASSES_ROOT
|
|
; <applicationID> = <"description">
|
|
; shell
|
|
; <verb> = <"menu-item text">
|
|
; command = <"command string">
