I am interested to know how can I do the same thing that the apllication listed below does:
Start Menu Calculator

I want to know how can I create an custom tab in Start Menu Search and then handle it with my WPF application. It should only be enabled until my application is running.( Just like what The calculator does )

I read something about windows API Code Pack and I downloaded it but I don’t know how can I use it. I searched through it but I didn’t find anything.( If you know how I could do this using with Windows API Code Pack, please write an example that explains how to do it in C#)

    • The main exe “Start Menu Calculator.exe” installs a windows hook (using SetWindowsHookEx) into explorer.exe. The hook is implemented as usual in SBLib.dll which is then injected into Windows Explorer’s memory space.

    • This hook searches for window handles belonging to the search box. See a discussion around this here:
      How do I get a “handle” on the Windows Search textbox? and probably sub classes the search box windows (if you kill the “Start Menu Calculator.exe” process abruptly, it crashes Windows Explorer too… which kinda confirms this)

    • It then reacts to key presses, and I suppose it butchers up the result window. In the hierarchies of Windows, I think it’s a Window named “Desktop Search Open View”, you can get to it with SPY++ under “Start Menu”, aside the windows mentioned in the msdn forum above.

    So, no nice API behind this nice application. Massive hacks instead 🙂

    I think however, some level of integration is possible, using documented behavior, with the search box. I have not dug further, but there is the notion of federated search in Windows (Windows 7 Federated Search). I don’t see if this would be capable of reacting instantaneously to what the user types in though…

    As a side note, if you’re also looking for a way to run javascript code from C#, there is a question here on SO that says it all: parse and execute JS by C#
