Seek -- by Phi

Navigating the Start Menu can be a hassle, especially if you have installed many programs over time. 'Seek' lets you specify a case-insensitive key word/phrase that it will use to filter only the matching programs and directories from the Start Menu, so that you can easily open your target program from a handful of matched entries. This eliminates the drudgery of searching and traversing the Start Menu.

;  I have a lot of fun coding this, and hope you will

;
; HOW TO 'SEEK':
;
; 1. 'Seek' is an AutoHotkey script. You can either run it
;    as Seek.ahk (original script) or Seek.exe (compiled
;    executable).
;
;    To obtain Seek.exe, you can download Seek.zip (includes
;    both the source code and the compiled binary) from
;    http://home.ripway.com/2004-10/188589/
;    Otherwise, you can compile Seek.ahk on your own by
;    using AutoHotkey's Ahk2Exe.exe compiler, or you can
;    ask me for a copy via email. The filesize is small at
;    about 200 kbytes. I can be reached at: phi1618 (*a.t*)
;    gmail :D0T: com.
;
;    To use Seek.ahk, first, you'll need to install
;    AutoHotkey v1.0.25 or higher on your PC (download from
;    http://www.autohotkey.com). Next, run the command:
;
;    X:\myTools\AutoHotkey\AutoHotkey.exe Y:\myAHK\Seek.ahk
;
;    Remember to replace X:\myTools and Y:\myAHK with
;    the proper directory names on your PC.
;
; 2. You can place the executable Seek.exe anywhere you
;    want. There is no installation required, it doesn't
;    write anything to your registry, and it doesn't
;    access the Internet at all (no phoning home). To
;    uninstall, simply delete Seek.exe.
;
;    The only 2 files 'Seek' creates are placed in your
;    TMP directory:
;
;      a. _Seek.key  (cache file for last query string)
;      b. _Seek.list (cache file for directory listing)
;
;    If you're a purist, you can delete them manually
;    when you decide to remove 'Seek' from your system.
;
; 3. The most convenient way to run 'Seek' is via a
;    shortcut/hotkey. If you are not already using any
;    hotkey management program on your PC, I highly
;    recommend AutoHotkey. If you don't intend to install
;    any hotkey management program at the moment, you can
;    make use of Windows shortcut feature and bind a
;    shortcut key (e.g. ALT-F1) to launch 'Seek'. This is
;    important so that you can run 'Seek' at anytime and
;    anywhere.
;
; 4. When you run 'Seek' for the first time, it'll scan
;    your Start Menu, and save the directory listing into
;    a cache file.
;
;    The following directories are included in the scanning:
;    - %A_StartMenu%
;    - %A_StartMenuCommon%
;
;    By default, subsequent runs will read from the
;    cache file so as to reduce the loading time. For
;    more info on options, run 'Seek.exe -help'. If you
;    think your Start Menu doesn't contain too many
;    programs, you can choose not to use the cache and
;    instruct 'Seek' to always do a directory scan (via
;    option -scan).  That way, you will always get the
;    latest listing.
;
; 5. When you run 'Seek', a window will appear, waiting
;    for you to enter a key word/phrase. After you have
;    entered a query string, a list of matching records
;    will be displayed. Next, you need to highlight an
;    entry and press <Enter> or click on the 'Open'
;    button to run the selected program or open the
;    selected directory.
;
;*****************************************************************
;
; TECHNICAL NOTES:
;
; - 'Seek' requires Chris Mallett's AutoHotkey v1.0.25
;   or higher version (http://www.autohotkey.com).
;   Thanks to Chris for his great work on AutoHotkey. :)
;
; - The following environment variables must be valid:
;   a. TMP
;
;*****************************************************************
;
; KNOWN PROBLEMS:
;
; - Nil
;
;*****************************************************************
;
; IMPLEMENTED SUGGESTIONS:
;
; - Highlight 1st matching record by default so that
;   user can just hit <Enter> to run it.
;   (Suggested by Yih Yeong)
;
; - Enable double-click on the listing of the search
;   results to launch the program.
;   (Suggested by Yih Yeong & Jack)
;
; - Auto real-time incremental search.
;   (Suggested by Rajat)
;
; - Fuzzy search when user enters multiple query strings,
;   separated by space.
;   (Suggested by Rajat)
;
;*****************************************************************
;
; SUGGESTED FEATURES (MAY OR MAY NOT BE IMPLEMENTED):
;
; - Log the launch history. List the most frequently
;   used programs at the top of the search results.
;   (Suggested by Yih Yeong)
;
; - Instead of using list box, can it display a series
;   of application icons so that hovering the cursor
;   over the icon will display a tooltip containing the
;   program information (path, etc).
;   (Suggested by Yih Yeong)
;
; - Instead of matching text in the middle, match only
;   those program/directory names that begin with the
;   query string.
;   (Suggested by Stefan)
;
; - Add favorites management. Launch group of programs
;   in a single run.
;   (Suggested by Atomhrt)
;
; - Integrate Seek into the Windows taskbar/toolbar so that
;   it is always available and there is no need to bind a
;   hotkey to launch Seek.
;   (Suggested by Deniz Akay)
;
; - Search by wildcards/regex.
;   (Suggested by Steve)
;
;*****************************************************************
;
; CHANGE HISTORY:
;
; * v1.1.0
; - Initial release.
;
; * v1.1.1
; - Removed maximise-window option since some programs don't
;   function well with it.
; - Added double-click detection to trigger 'Open' function.
;
; * v2.0.0
; - Integrated the 'Seek' popup window into the output screen
;   so that user can re-enter the query string to search for
;   something else without having to exit and run Seek again.
; - Added 'Scan Start-Menu' button.
; - Added real-time incremental search which will auto
;   filter for matching records while you type away,
;   without waiting for you to press <Enter>.
; - Added internal switch (TrackKeyPhrase) to track search-string.
; - Added internal switch (ToolTipFilename) to show filename
;   using tooltip.
;
; * v2.0.1
; - Added horizontal scrollbar to ListBox so that very
;   long records will not be cut-off in the middle.
;
; * v2.0.2
; - Allowed user to add their own customised list of directories
;   to be included in the scanning. User just needs to create a
;   text file 'Seek.dir' in the same directory as Seek.exe or
;   Seek.ahk, and specify the full path of the directory to be
;   added, one directory per line. Do not enclose the path in
;   quotes or double-quotes.
;
; * v2.0.3
; - Added /on option to DIR-command to sort by name.
; - Fuzzy search when user enters multiple query strings,
;   separated by space, for e.g. "med pla". It's a match
;   when all the strings ("med" & "pla") are found. This
;   will match "Media Player", "Macromedia Flash Player",
;   "Play Medieval King", "medpla", "plamed".
; - Corrected tab-movement sequence by adding all buttons
;   right from the start, but disable them until they can
;   be used.
; - Added status bar to replace tooltip-feedback.
; - Removed obsolete internal switch (ToolTipFilename).
; - Replaced the use of "dir" command with AutoHotkey's
;   own "Loop" command for scanning directory contents.
;   "dir" cannot handle extended character set and thus
;   non-English (e.g German) directory and filename are
;   captured wrongly. (Thanks Wolfgang Bujatti and
;   Sietse Fliege for testing this modification)
; - Added internal switch (ScanMode) to define whether
;   files and/or directories are to be included in scan.
; - Replaced hardcoded directory paths of Start Menu with
;   built-in variables A_StartMenu, A_StartMenuCommon.
;   With this, Seek now works for different locales with
;   different naming convention of the Start Menu.
;   (Thanks Wolfgang Bujatti and Sietse Fliege for help
;   in testing another method before these new variables
;   are available.)
; - Added the pre-selection of the last-run program
;   record so that a quick double-<ENTER> will run it.
