reference execuatable's full path

This is an extension to the questions I asked previously.
I need to find out the full path of my executable written in VC.    argv[0] only shows what's typed at the command line, but not including the FULL path.

I tried to use FindExecutable function. Once I included 'shellapi.h".  compile errors are all refering to the shellapi.h.  But I didn't change anything to it.  Any other files I need to include before shellapi.h?

what's the best way to find out the full path of a excutable?  or if you can reference it like you do to the working directory, that'll be good.

You should be able to find the full path from using the information that is available in argv[0].  Remember, there are three ways that the program got found initially.  Either the pathname specified in argv[0] is fully qualified (i.e. C:\x\y\z\file.exe) and it can be found directly.  It may be relative (i.e. ..\x\y\z\file.exe or x\y\z\file.exe) and it can be found by using the current working directory as a base.  Lastly, it may be found from the PATH environment variable which can be searched and the file located.  There is no "magic" way to get the full pathname, but using the above information you can find it the same way that the operating system does.
