I wanted to ensure that my switch statement in my implementation of IInternetSecurityManager::ProcessURLAction had a case for every possible documented URLACTION. I wrote the following short command line sequence to see the list of all URLACTIONs in the SDK header file not found in my source file:

grep URLACTION urlmon.idl | sed 's/.*\(URLACTION[a-zA-Z0-9_]*\).*/\1/g;' | sort | uniq > allURLACTIONs.txt
grep URLACTION MySecurityManager.cpp | sed 's/.*\(URLACTION[a-zA-Z0-9_]*\).*/\1/g;' | sort | uniq > myURLACTIONs.txt
comm -23 allURLACTIONs.txt myURLACTIONs.txt

I'm not a sed expert so I had to read the sed documentation, and I heard about comm from Kris Kowal's blog which happilly was in the Win32 GNU tools pack I already run.

But in my effort to learn and use PowerShell I found the following similar command line:

diff 
(more urlmon.idl | %{ if ($_ -cmatch "URLACTION[a-zA-Z0-9_]*") { $matches[0] } } | sort -uniq) 
(more MySecurityManager.cpp | %{ if ($_ -cmatch "URLACTION[a-zA-Z0-9_]*") { $matches[0] } } | sort -uniq)

In the PowerShell version I can skip the temporary files which is nice. 'diff' is mapped to 'compare-object' which seems similar to comm but with no parameters to filter out the different streams (although this could be done more verbosely with the ?{ } filter syntax). In PowerShell uniq functionality is built into sort. The builtin -cmatch operator (c is for case sensitive) to do regexp is nice plus the side effect of generating the $matches variable with the regexp results.

When you run clip.exe, whatever comes into its standard input is put onto the clipboard. So when you need to move the result of something in your command window somewhere else you can pipe the result into clip.exe. Then you won't have to worry about the irritating way cmd.exe does block copy/pasting and you avoid having to manually fixup line breaks in wrapped lines. For instance, you can put the contents of a script into the clipboard with:

more cdo.cmd | clip

I've got a lot of stuff dumped in my bin folder that I sync across all my PCs so I didn't realize that clip.exe is a part of standard Windows installs.

Nice for avoiding the block copy in cmd.exe but I'd prefer to have the contents sort of tee'd into the clipboard and standard output. So TeeClip.ps1:

$input | tee -var teeclipout | clip;
$teeclipout;

I've made two simple command line tools related to the console window and Win7 jump lists. The source is available for both but neither is much more than the sort of samples you'd find on MSDN =).

• SetAppUserModelId
• SetJumpList

SetAppUserModelId lets you change the Application User Model ID for the current console window. The AppUserModelId is the value Win7 uses to group together icons on the task bar and is what the task bar's jump lists are associated with. The tool lets you change that as well as the icon and name that appear in the task bar for the window, and the command to launch if the user attempts to re-launch the application from its task bar icon.

SetJumpList lets you set the jump list associated with a particular AppUserModelId. You pass the AppUserModelId as the only parameter and then in its standard input you give it lines specifying items that should appear in the jump list and what to execute when those items are picked.

I put these together to make my build environment easier to deal with at work. I have to deal with multiple enlistments in many different branches and so I wrote a simple script around these two tools to group my build windows by branch name in the task bar, and to add the history of commands I've used to launch the build environment console windows to the jump list of each.

I previously described my desire to hook my Outlook calendar up to my Google calendar. I just found out that I can do this and the reverse as both support publishing calendars to the Internet. The following are how I set this up under Outlook 2010 and Google Calendar:

In Outlook, I go to the calendar view, right click on my calendar and select "Share Publish to Office.com". At this point I can change the permissions to allow anonymous Internet access, and under Detail change between 'Full details' (full calendar), 'Limited details' (subject lines & availability only), 'Availability only'. Availability only is almost just what I want -- I'd also like to include location but availability only is good enough. After hitting OK here I get a 'Do you want to send an invitation...' dialog box. I hit 'Yes' and I can copy the webcals:// URL out of the email window that opens up. Next, to add it to my Google calendar, I open http://www.google.com/calendar/, and under 'Other calendars', I select 'Add Add by URL', paste in that webcals:// URL but change the 'webcals' at the start to 'https'.

In Google Calendar, I can click on my calendar name under 'My calendars', select 'Calendar settings', and on the new page, look under 'Calendar Address', click the ICAL icon, and copy the URL in the new dialog. Now back in Outlook I go to the Calendar view, right click on 'My Calendars', and select 'Add Calendar From Internet...'. In the new dialog that pops up I paste in the URL from Google Calendar.

In this fashion I can share public calendar data between my personal and work calendars.
