|
||
* About verbs. A registry key (the name of that key is known as ProgID)
|
||
* can contain a "shell" subkey, which can then contain a number of verb
|
||
* subkeys (the most common being the "open" verb), and each of these
|
||
* contains a "command" subkey, which has a default string value that
|
||
* is the command to be run.
|
||
* Most ProgIDs are in HKEY_CLASSES_ROOT, but some are nested deeper in
|
||
* the registry (such as HKEY_CURRENT_USER\\Software\\<softwarename>).
|
||
*
|
||
* Verb selection works like this (according to https://docs.microsoft.com/en-us/windows/win32/shell/context ):
|
||
* 1) If "open" verb is available, that verb is used.
|
||
* 2) If the Shell subkey has a default string value, and if a verb subkey
|
||
* with that name exists, that verb is used.
|
||
* 3) The first subkey found in the list of verb subkeys is used.
|
||
* 4) The "openwith" verb is used
|
||
*
|
||
* Testing suggests that Windows never reaches the point 4 in any realistic
|
||
* circumstances. If a "command" subkey is missing for a verb, or if it has
|
||
* an empty string as its default value, the app launch fails
|
||
* (the "openwith" verb is not used, even if it's present).
|
||
* If the command is present, but is not valid (runs nonexisting executable,
|
||
* for example), then other verbs are not checked.
|
||
* It seems that when the documentation said "openwith verb", it meant
|
||
* that Windows invokes the default "Open with..." dialog (it does not
|
||
* look at the "openwith" verb subkey, even if it's there).
|
||
* If a verb subkey that is supposed to be used is present, but it lacks
|
||
* a command subkey, an error message is shown and nothing else happens.

%~ - replace with all parameters starting with and following the second parameter
|
||
%0 or %1 the first file parameter. For example "C:\\Users\\Eric\\Destop\\New Text Document.txt". Generally this should be in quotes and the applications command line parsing should accept quotes to disambiguate files with spaces in the name and different command line parameters (this is a security best practice and I believe mentioned in MSDN).
|
||
%<n> (where N is 2 - 9), replace with the nth parameter
|
||
%s - show command
|
||
%h - hotkey value
|
||
%i - IDList stored in a shared memory handle is passed here.
|
||
%l - long file name form of the first parameter. Note win32 applications will be passed the long file name, win16 applications get the short file name. Specifying %L is preferred as it avoids the need to probe for the application type.
|
||
%d - desktop absolute parsing name of the first parameter (for items that don't have file system paths)
|
||
%v - for verbs that are none implies all, if there is no parameter passed this is the working directory

%w - the working directory
