I want to shell "wordpad.exe" from my application. So, in my code I am going to the registry to find path to the "wordpad.exe" and get return from windowsXP as it is in registry:
%programfiles%\windowsnt\accessories\wordpad.exe



When I put this path into shell(...) I obviously get error "file not found" , because %programfiles% cannot be recognized.

So , now I am looking for some way to find in the windows system were this " environment variable" is decoded to transform it in the real path.

Appreciate your advise.
