Custom Column handler for All folders

Shravan Kumar · Sep 16, 2003

Hi group, and especially Kelly from whom I have high hopes of answering this
question!

Is there a way for me to add my custom column handler
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/pl
atform/shell/programmersguide/shell_int/shell_int_extending/extensionhandler
s/columnproviderhandlers.asp) to all folders on Windows XP ?

If my users install my custom column handler, I want it to get enabled for
all folders.

Thanks!

Hi,

Have you started from the basics and worked your way up?

HKEY_CLASSES_ROOT\Folder\shellex\ColumnHandlers. Subkey: GUID (UUIDGEN).

If so, I would have to mess with it. Good luck!

Hi Kelly,

I have created that HKEY_CLASSES_ROOT\Folder\shellex\ColumnHandlers key and
added my column handler.

The problem is that for each folder I need to right click on the details
bar, select "More..." and then I am finally able to 'check' my custom
column.

Once I added it, I used your suggestion given in another post here to apply
the same folder settings to all folders.

Now, this required a bit of user interaction from my end.

What I ideally want to do is package my shell extension in an installer, and
from it run some kellys-magic-reg-script, and viola! the column come up on
its own for the details view on its own!

Am I asking for too much

Thanks!

Hi Kelly,

I am attaching a sample Column handler that give information about MP3s
The ClassID is {AC146E80-3679-4BCA-9BE4-E36512573E6C}

On registering it, I am able to add columns like "MP3 Year" to my details
view.

How could I package this dll with a reg script in an installer, so it gets
enabled when the installer is run, and users dont need to add this column on
their own?

Thanks!
