Get Executable path

A while ago I was developing an addin that utilised Winzip and realised that not every one puts the Winzip exe file (or even uses winzip, perhaps opting for another zip utility) in the default setup location, so I needed to come up with a way to get this.
eg on my system the exec file or default application to open it……..
C:Program FilesWinZipWINZIP32.EXE

This is what I came up with ….. I’d be interested in other ways you may have to get the files asscociated exec
program & location, possibly using the Registry, let us all know.

So if you ever need to know the default or current user setup application and location to run a particular document then give this a try.

Just plug in the file extension or the path to a document to get the executable file & location that opens it.

Try plugging in your own to see what you get………….

PROS: Utilises core API so every Win32 OS should be able to run this.
CONS: It gets the ASSOCIATED Application i.e what ever the user has set-up to run a particular file extension
so don’t assume they run the same application as you. i.e if you expect them to be using winzip then
check the associated program before utilising your code that may depend on winzip.

I have left the extraction of the various elements of “Path only” & “Executable only” up to you. There are a number of ways out there to get these elements :)
