How to create two instances using Shell Instance Objects
hayate
After reading the article "Creating Shell Extensions with Shell
Instance Objects" written by Raymond Chen, I use the method to create a
context menu. Here is an example
REGEDIT4
[HKEY_CLASSES_ROOT\Directory\Background\shellex\ContextMenuHandlers\SuperHidden]
@="{537F6DED-62F4-45f9-B832-F0E86BD0F136}"
[HKEY_CLASSES_ROOT\CLSID\{537F6DED-62F4-45f9-B832-F0E86BD0F136}\InProcServer32]
@=hex(2):25,53,79,73,74,65,6d,52,6f,6f,74,25,5c,73,79,73,74,65,6d,33,32,5c,73,\
68,64,6f,63,76,77,2e,64,6c,6c,00
"ThreadingModel"="Apartment"
[HKEY_CLASSES_ROOT\CLSID\{537F6DED-62F4-45f9-B832-F0E86BD0F136}\Instance]
"CLSID"="{3f454f0e-42ae-4d7c-8ea3-328250d6e272}"
[HKEY_CLASSES_ROOT\CLSID\{537F6DED-62F4-45f9-B832-F0E86BD0F136}\Instance\InitPropertyBag]
"method"="ShellExecute"
"Param1"="D:\\Program Files\\SuperHidden\\SuperHidden.vbs"
"command"="Display/Hidden Files"
"CLSID"="{13709620-C279-11CE-A49E-444553540000}"
It works well. But now I need an other menu for other task, I found it
cannot display two menus if I add similar keys to the registry.
Is it possible to create 2 instance of object or display mutiple menus
in one instance.
Thx

From the single instance you can add many menu items. There's no need
to add further registry settings, just modify the code in your
QueryContextMenu function to insert additional menu items.

U misunderstanded me. I didn't create a shell extension of COM server,
I just created some reg keys. you can see this article
http://msdn2.microsoft.com/en-us/library/ms997573.aspx for reference.
Or U can import my registry file the above and see the result.

Ah my mistake, I wasn't even aware of those.

The problem is that the Automation context menu object uses the "open" verb for its menu item. The shell automatically removes menu items with duplicate verbs, which is why your second instance object doesn't appear. And if the "open" verb had already existed in the Directory\Background menu, your first instance object wouldn't have showed up either.

Is there a way to change the verb the object use?
I searched the whole internet and couldn't find anything more about
Shell Instance Object except the article of raymond. can U plz tell how
to fetch the detailed info about something like this. Sometimes I need
internal info about some tech and I found nowhere to get it.
For instance, the value here such as "ShellExecute" "Command" "Param1",
How to get the names of these values and the usage?

Unfortunately not - it's hard coded.

Well, the Automation context menu object isn't documented and presumably is only intended for the shell's internal use. How did you discover it - just by trawling the registry?
